Description

Technical Field

[0001] This application relates to the field of nuclear power plant equipment control technology, and in particular to a method and system for isolating and transferring nuclear power plant system equipment suitable for power plant commissioning. Background Technology

[0002] Currently, before a nuclear power plant can be put into operation, it needs to go through various stages such as design, civil construction, installation, commissioning and trial operation. Each system and equipment in the nuclear power plant must undergo various tests such as individual tests, start-up tests and system function tests to ensure that the installed systems and equipment meet the design requirements and relevant guidelines and regulations before they can be put into operation.

[0003] During commissioning and testing of various systems and equipment in a nuclear power plant, isolation and handover are required between different departments. However, the handover of nuclear power plant systems and equipment is generally based on the personal experience of the staff, which is prone to errors and omissions and has low efficiency.

[0004] Therefore, how to conduct high-quality and efficient handover of nuclear power plant system equipment during the isolation and handover phase has become an urgent problem to be solved. Summary of the Invention

[0005] This application aims to at least partially address one of the technical problems in the related art.

[0006] Therefore, the first objective of this application is to propose a method for the isolation and handover of nuclear power plant system equipment suitable for power plant commissioning. This method enables the nuclear power plant system equipment to be handed over with high quality and efficiency during the isolation and handover process, achieving effective isolation of system equipment to ensure the safety of commissioning and testing, and ensuring that the system equipment information is complete and detailed, thus providing a foundation for smooth handover to production and long-term stable operation of the unit.

[0007] The second objective of this application is to propose a nuclear power plant system equipment isolation and handover system suitable for power plant commissioning.

[0008] The third objective of this application is to propose an electronic device.

[0009] The fourth objective of this application is to provide a computer-readable storage medium.

[0010] To achieve the above objectives, the first aspect of this application is to propose a method for the isolation and handover of nuclear power plant system equipment suitable for power plant commissioning, comprising the following steps: After the installation of the nuclear power plant system equipment is completed, the system equipment is handed over from the construction party to the commissioning department by signing the Installation Completion Status Report (EESR) document package. The EESR document package includes all construction contents on the construction site. For the system equipment, an isolation boundary for the debugging area is defined, and an isolation transfer to business (TOB) application is initiated. After the TOB application is approved and the TOB certificate is signed, a TOB isolation area is established according to the isolation boundary, and various debugging tests are carried out in the TOB isolation area. In response to the completion of the isolation handover to the TOB of the system equipment and the completion of individual commissioning and the test run of the rotating equipment with power and medium, a maintenance handover to the TOM application is initiated, and after signing the TOM certificate, the maintenance task of the system equipment is transferred from the commissioning department to the maintenance department; In response to the system equipment having been commissioned and possessing long-term operational capability, a temporary operation transfer application to TOTO is initiated, and after signing the TOTO certificate, the temporary operation management task of the system equipment is transferred from the commissioning department to the operation management department.

[0011] Optionally, after initiating the TOB (Transfer to Business) isolation application and obtaining approval and a TOB certificate, a TOB isolation zone is established based on the isolation boundary, and various debugging tests are conducted in the TOB isolation zone, including: Enter the TOB handover plan, create a TOB application based on the TOB handover plan, and compile a TOB handover document package, wherein the TOB handover document package includes a TOB boundary list, isolation requirements, and a TOB boundary diagram; Verify the TOB handover document package; after the TOB handover document package has been approved, check for conflicts between the TOB handover boundary and external systems. Review whether the TOB handover document package that has passed the conflict detection complies with the relevant specifications and is complete, and distribute the reviewed documents to the TOB boundary receiving department and the operation isolation department; The TOB boundary receiving department and the operation isolation department conduct multiple reviews of the TOB handover document package and the TOB boundary in sequence. After the multiple reviews are passed, a joint TOB inspection is organized and a joint inspection notice is issued. The joint inspection opinions obtained through joint inspection are classified into categories and entered into the system. The classified joint inspection opinions include Category I items and Category II items. The joint inspection comments are processed, the EESR document is confirmed to be signed and the processing of the first category of items is completed, and a handover approval is proposed. After the handover approval is approved by the commissioning department and the owner's operation department multiple times, a TOB handover certificate is generated. An isolation operation order is generated based on the TOB transfer certificate, isolation is implemented according to the isolation operation order, and the isolation operation order is returned after the isolation is completed. After confirming the completion of TOB on-site isolation based on the returned isolation operation form, issue a TOB handover announcement and transfer the remaining Category II items to TOB legacy items for management.

[0012] Optionally, after the TOB boundary receiving department and the operational isolation department have conducted multiple reviews of the TOB handover document package and the TOB boundary in sequence, the method further includes: If the document fails to meet the requirements after multiple reviews, it will be returned to the debugging and handover department for modification. Resubmit the revised document for review.

[0013] Optionally, the organization's TOB joint inspection and issuance of joint inspection notices includes: defining a receiving group for the joint inspection notice and notifying relevant personnel in the receiving group of the joint inspection information via joint inspection information email.

[0014] Optionally, the step of classifying and entering the joint inspection opinions obtained through joint inspection includes: setting the latest completion time for the joint inspection opinions; the step of processing the joint inspection opinions includes: for unprocessed Category I items, determining whether to initiate the process of converting Category I items to Category II items.

[0015] Optionally, before signing the Installation Completion Status Report (EESR) document package, the method further includes: checking the Installation Completion Status Report (EESR) document package and comparing whether the information of the transferred system equipment is consistent with the actual construction situation.

[0016] Optionally, before initiating the maintenance handover TOM application, the process further includes: verifying whether the results of the unit commissioning and the energized and medium-loaded test rotation of the rotating equipment meet the preset technical standards; and before initiating the temporary operation handover TOTO application, the process further includes: assessing whether the system equipment response speed, parameter control accuracy, and continuous operating time meet the standards.

[0017] To achieve the above objectives, a second aspect of this application also proposes a nuclear power plant system equipment isolation and handover system suitable for power plant commissioning, comprising the following modules: The handover module is used to transfer the nuclear power plant system equipment from the construction party to the commissioning department by signing the Installation Completion Status Report (EESR) document package after the installation is completed. The EESR document package includes all construction content at the construction site. The debugging module is used to define the isolation boundary of the debugging area for the system equipment and initiate an isolation transfer (TOB) application. After the TOB application is approved and the TOB certificate is signed, a TOB isolation area is established according to the isolation boundary, and various debugging tests are carried out in the TOB isolation area. The first transfer module is used to initiate a maintenance transfer to maintenance (TOM) application in response to the completion of the isolation transfer (TOB) of the system equipment and the completion of individual commissioning and the test rotation of the rotating equipment with electricity and medium. After signing the TOM certificate, the maintenance task of the system equipment is transferred from the commissioning department to the maintenance department. The second transfer module is used to initiate a temporary operation transfer to TOTO application in response to the system equipment having been debugged and having long-term operational capability, and after signing the TOTO certificate, to transfer the temporary operation management task of the system equipment from the debugging department to the operation management department.

[0018] To achieve the above objectives, a third aspect of this application also provides an electronic device, comprising: at least one processor; and A memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform a nuclear power plant system equipment isolation and handover method suitable for power plant commissioning as described in any one of the first aspects above.

[0019] To achieve the above objectives, the fourth aspect of this application also proposes a non-transitory computer-readable storage medium storing a computer program thereon, which, when executed by a processor, implements the nuclear power plant system equipment isolation and handover method applicable to power plant commissioning as described in any of the first aspects above.

[0020] The technical solutions provided by the embodiments of this application bring at least the following beneficial effects: This application can be applied to the isolation and handover of nuclear power plant system equipment in different scenarios such as EPC (Engineering, Procurement, and Construction) models, realizing high-quality and planned handover of system equipment from the construction and installation team to the commissioning team, ensuring the smooth conduct of subsequent commissioning tests. Therefore, this application enables high-quality and efficient handover of nuclear power plant system equipment during the isolation and handover process, achieving effective isolation of system equipment to ensure the safety of commissioning tests, and ensuring complete and detailed system equipment information, providing a foundation for smooth handover to production and long-term stable operation of the unit. This application can significantly improve the efficiency and quality of nuclear power plant system equipment isolation and handover, reduce the cost of the isolation and handover process, and is easy to implement in practical applications.

[0021] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] The following description, with reference to the accompanying drawings, describes a method and system for isolating and transferring nuclear power plant system equipment suitable for power plant commissioning, as proposed in an embodiment of this application.

[0025] Figure 1 This is a flowchart illustrating a nuclear power plant system equipment isolation and handover method suitable for power plant commissioning, as proposed in an embodiment of this application. Figure 1 As shown, the method includes the following steps: Step S101: After the installation of the nuclear power plant system equipment is completed, the system equipment is transferred from the construction party to the commissioning department by signing the Installation Completion Status Report (EESR) document package. The EESR document package includes all construction content at the construction site.

[0026] It should be noted that this application is applicable to the isolation and handover of nuclear power plant system equipment in various scenarios, including EPC (Engineering, Procurement, and Construction) models. This application employs a multi-stage handover method combining End-of-Erection Status Report (EESR), Take Over for Blocking (TOB), Take Over for Maintenance (TOM), and Take Over for Temporary Operation (TOTO), clearly defining the handover conditions, responsible parties, and operational procedures for each stage. To enable data interaction during the isolation and handover process of nuclear power plant system equipment, this application constructs a nuclear power plant system equipment isolation and handover system. This system configures corresponding clients for various departments and personnel to facilitate data interaction such as document approval between different terminals. The approval, verification, and handover of specific document data can be processed by the corresponding clients according to preset algorithms, which will be referred to as processing by various departments or personnel in this application.

[0027] Specifically, this application first involves the handover of the EESR, with the handover process proceeding from the construction party to the commissioning party.

[0028] In one embodiment of this application, before signing the Installation Completion Status Report (EESR) document package, the method further includes: inspecting the EESR document package and comparing whether the information of the transferred system equipment is consistent with the actual construction situation.

[0029] Specifically, the EESR (Establishment of Installation Completion Report) package serves as the direct interface document for installation and commissioning activities. It must be jointly confirmed by the contractor and commissioning party to ensure its completeness and accuracy before signing, guaranteeing that the transferred system equipment information matches the actual construction situation. After the nuclear power plant system equipment installation is completed, the contractor compiles and submits the EESR package. This package is the direct interface document for installation and commissioning activities, comprehensively recording all on-site construction work completed by the contractor, including equipment installation locations, installation processes, material specifications, and construction inspection records. The contractor and commissioning party jointly review the contents of the EESR package. Once they confirm that the information matches the actual construction situation and that the system equipment installation meets design requirements, both parties sign the EESR package. At this point, the system equipment is officially transferred from the contractor to the commissioning party.

[0030] Step S102: Define the isolation boundary of the debugging area for the system equipment and initiate an isolation transfer (TOB) application. After the TOB application is approved and the TOB certificate is signed, establish the TOB isolation area according to the isolation boundary and conduct various debugging tests in the TOB isolation area.

[0031] Specifically, this application involves a TOB (Transfer-of-Business) handover, whereby the commissioning team establishes an isolated area and intervenes in the commissioning process. After obtaining the EESR (Electronic Execution Record) file transmitted by the system, the commissioning team delineates the isolation boundaries of the commissioning area and initiates a TOB application. Once the TOB certificate is signed, the operations department implements isolation and establishes the TOB isolation area. The completion of the TOB signifies the commissioning department's formal intervention in system commissioning, and the test leader conducts test activities within the TOB area.

[0032] To more clearly illustrate the specific implementation process of initiating a TOB (Transfer-of-Blank) application for isolation and transfer, establishing a TOB isolation zone based on the isolation boundary after the TOB application is approved and the TOB certificate is signed, and conducting various debugging tests in the TOB isolation zone, the following is an exemplary description of a specific isolation and transfer method proposed in one embodiment of this application. Figure 2 This is a flowchart illustrating a specific method for the isolation, handover, and commissioning of nuclear power plant system equipment, as proposed in an embodiment of this application. Figure 2 As shown, the method includes the following steps: Step S201: Enter the TOB handover plan, create a TOB application based on the TOB handover plan, and compile a TOB handover document package, which includes a TOB boundary list, isolation requirements, and a TOB boundary diagram.

[0033] Specifically, the commissioning plan engineer enters the TOB handover plan and reminds the commissioning system manager to prepare the handover application documents. The commissioning system manager creates the TOB application, enters the TOB handover document package containing the TOB boundary list, isolation requirements, and TOB boundary diagram, and submits it for approval.

[0034] Step S202: Verify the TOB handover document package. After the TOB handover document package is approved, check for conflicts between the TOB handover boundary and external systems.

[0035] Specifically, the team leader of the commissioning team verifies the TOB handover document package. After approval, it is submitted to the commissioning isolation manager; otherwise, it is returned to the person in charge of the commissioning system. Then, the commissioning isolation manager reviews the TOB handover boundary, checking for conflicts between the handover boundary and other systems that have already been handed over to TOB and TOTO. At the same time, the commissioning engineer reviews the conflicts between the TOB handover boundary and the work order.

[0036] Step S203: Review whether the TOB handover document package that has passed the conflict detection complies with the relevant specifications and whether the content is complete, and distribute the approved documents to the TOB boundary receiving department and the operation isolation department.

[0037] Specifically, after the commissioning and handover engineer reviews the document for compliance, it is submitted to the owner's handover and production engineer for review of the document's completeness. After review, the owner's handover and production engineer distributes the document to the system head and operations isolation manager of the TOB boundary receiving department for review.

[0038] Step S204: The TOB boundary receiving department and the operation isolation department conduct multiple reviews of the TOB handover document package and the TOB boundary in sequence. After the multiple reviews are passed, a joint TOB inspection is organized and a joint inspection notice is issued.

[0039] Specifically, the receiving department's contact person, the receiving department's system manager, and the operation isolation manager review the TOB handover documents and boundaries in turn. After the review is passed and the operation isolation manager agrees to the joint inspection, the commissioning and handover engineer organizes the TOB joint inspection and issues a joint inspection notice.

[0040] In this embodiment of the application, after the TOB boundary receiving department and the operation isolation department conduct multiple reviews of the TOB handover document package and the TOB boundary in sequence, the method further includes: if the results of multiple reviews are unqualified, returning the document to the debugging handover department for modification; and resubmitting the modified document for review.

[0041] Specifically, if the receiving department's contact person, the receiving department's system manager, or the operation isolation manager needs to return the document after review, they must fill in the review comments and return it to the debugging and handover engineer. The debugging and handover engineer will then organize the debugging system manager to revise the document and resubmit it for review.

[0042] In this embodiment of the application, organizing TOB joint inspections and issuing joint inspection notices includes: defining a receiving group for the joint inspection notices and notifying relevant personnel in the receiving group of the joint inspection information via joint inspection information email.

[0043] Specifically, the isolation and handover system constructed in this application has a joint inspection information email notification function. The commissioning and handover engineer can customize the receiving group of the joint inspection notification to ensure that relevant personnel receive the joint inspection information in a timely manner.

[0044] Step S205: Classify the joint inspection opinions obtained through joint inspection into categories and enter the joint inspection opinions. The classified joint inspection opinions include Category I items and Category II items.

[0045] Specifically, the commissioning and handover engineer organizes relevant personnel to classify the joint inspection comments into Category I and Category II items. After the person in charge of the commissioning system enters and processes the joint inspection comments, the comments are submitted for confirmation by the person who submitted the comments.

[0046] In this embodiment, the joint inspection feedback items obtained through joint inspection are categorized and entered into the system, including setting a latest completion time for each feedback item. That is, when the person in charge of the debugging system enters a joint inspection feedback item, they must specify the latest completion time for that item. Step S206: Process the joint inspection comments, confirm that the EESR document is signed and the processing of the first type of item is completed, submit the transfer approval, and generate the TOB transfer certificate after the transfer approval has passed multiple approvals from the commissioning department and the owner's operation department.

[0047] Specifically, after the commissioning and handover engineer confirms the signature of the EESR document and completes the processing of Category I items, he / she submits a handover approval request. After approval by the head of the commissioning department or his / her authorized representative, the owner's handover engineer, and the head of the owner's operations department or his / her authorized representative, a TOB handover certificate and handover document package are generated.

[0048] In this embodiment of the application, the processing of joint inspection comments includes: for unprocessed Category I comments, determining whether to initiate the process of converting Category I comments to Category II comments. Specifically, for Category I comments that cannot be processed, it is necessary to confirm whether to initiate the process of converting Category I comments to Category II comments, and the corresponding process is executed after confirmation by the commenter.

[0049] Step S207: Generate an isolation operation order based on the TOB transfer certificate, implement isolation according to the isolation operation order, and return the isolation operation order after the isolation is completed.

[0050] Specifically, the operations isolation manager issues an isolation operation form, which is then received by the system head of the receiving department who goes to the site to implement the isolation. After the implementation is completed, the isolation operation form is returned to the isolation office, and the operations isolation manager confirms that the isolation is complete and then reports it to the commissioning and handover engineer.

[0051] Step S208: After confirming the completion of TOB on-site isolation based on the returned isolation operation form, issue a TOB handover announcement and transfer the remaining Category II items to TOB legacy items for management.

[0052] Specifically, the commissioning and handover engineer issues a TOB handover notice, the person in charge of the commissioning system posts it on-site, and at the same time, the relevant Category II joint inspection opinions at the TOB boundary are transferred to TOB legacy item management.

[0053] Step S103: In response to the completion of the isolation handover (TOB) of the system equipment and the completion of individual commissioning and the test run of the rotating equipment with power and medium, a maintenance handover (TOM) application is initiated, and after signing the TOM certificate, the maintenance task of the system equipment is transferred from the commissioning department to the maintenance department.

[0054] Specifically, after the individual commissioning of the system equipment that has completed the TOB handover is completed and the equipment is switched to a live-line test with medium, the person in charge of the test shall initiate a TOM application. After the TOM certificate is signed, the maintenance responsibility of the system equipment shall be transferred from the commissioning department to the maintenance department.

[0055] In one embodiment of this application, before initiating a maintenance transfer application (TOM), the process further includes: verifying whether the results of unit commissioning and rotating equipment energized and subjected to medium testing meet preset technical standards.

[0056] Specifically, this application embodiment involves a TOM (Transfer of Maintenance) handover, with the transfer direction from the commissioning department to the maintenance department. For system equipment that has completed a TOB (Transfer of Business) handover, after completing individual commissioning (e.g., testing the performance and functionality of a single device to ensure it meets design parameter requirements) and a test run with the equipment energized and carrying a working medium (e.g., simulating actual operating conditions to test the stability of the equipment under energized and working medium conditions), the person in charge of the test verifies the commissioning results. Once the results are confirmed to meet preset technical standards, a TOM application is initiated. Relevant departments review the TOM application and commissioning results. Upon approval, a TOM certificate is signed, and the maintenance responsibility for the system is officially transferred from the commissioning department to the maintenance department. The maintenance department then begins to be responsible for the daily maintenance and troubleshooting of the system equipment.

[0057] In step S104, in response to the system equipment having been commissioned and having long-term operational capability, a temporary operation transfer application to TOTO is initiated, and after signing the TOTO certificate, the temporary operation management task of the system equipment is transferred from the commissioning department to the operation management department.

[0058] Specifically, after the nuclear power plant system equipment has been commissioned and has initially achieved long-term operational capability, the person in charge of the test initiates a TOTO application. After the TOTO certificate is signed, the temporary operation and management responsibility of the system equipment is transferred from the commissioning department to the operation and management department.

[0059] In one embodiment of this application, before initiating a temporary operation handover (TOTO) application, the method further includes: assessing whether the system equipment response speed, parameter control accuracy, and continuous operating time meet the standards.

[0060] Specifically, this application embodiment involves a TOTO (Temporary Operational Transfer) process, with the transfer direction from the commissioning party to the operations management department. After the system equipment has been commissioned and initially possesses long-term operational capability, the test leader needs to conduct a comprehensive assessment of the system's operating parameters (such as pressure, temperature, and flow rate), functional integrity (such as the collaborative working capability of each subsystem), and stability (such as continuous operating time and parameter fluctuation range). Once the assessment meets the standards, a Temporary Operational Transfer (TOTO) application is initiated. After review and approval and signing of the TOTO certificate, the temporary operational management responsibility of the system is transferred from the commissioning department to the operations management department. The operations management department operates and manages the system according to the temporary operational procedures, preparing the system for formal operation.

[0061] In summary, the nuclear power plant system equipment isolation and handover method applicable to power plant commissioning, as described in this application, is applicable to the isolation and handover of nuclear power plant system equipment in various scenarios, including EPC (Engineering, Procurement, and Construction) models. It achieves high-quality, planned handover of system equipment from the construction and installation team to the commissioning team, ensuring the smooth conduct of subsequent commissioning tests. Therefore, this method enables high-quality and efficient handover of nuclear power plant system equipment during the isolation and handover process, achieving effective isolation of system equipment to ensure the safety of commissioning tests, and ensuring complete and detailed system equipment information, providing a foundation for smooth handover to production and long-term stable operation of the unit. This method significantly improves the efficiency and quality of nuclear power plant system equipment isolation and handover, reduces the cost of the isolation and handover process, and is easy to implement in practical applications.

[0062] Based on the above embodiments, in order to more clearly illustrate the specific implementation process of this application for isolating and transferring nuclear power plant system equipment and establishing commissioning boundaries for commissioning activities, the following embodiment combines... Figure 3 Please provide a detailed explanation.

[0063] based on Figure 3 The principle of the system equipment isolation and handover process shown in the illustration is illustrated below. This application proposes another specific method for the isolation, handover, and commissioning of nuclear power plant system equipment, which includes the following steps: Step S1: Enter the TOB handover plan. The commissioning plan engineer enters the TOB handover plan and reminds the person in charge of the commissioning system to prepare the handover application documents.

[0064] Step S2: Create a TOB application and prepare the application documents. The person in charge of debugging the system creates a TOB application, enters the TOB handover document package, including the TOB boundary list, isolation requirements, and TOB boundary diagram, and submits it for approval after completion.

[0065] Step S3: Verify the TOB file package. The team leader of the debugging team verifies the TOB transfer file package. If the verification fails, it is returned to the person in charge of the debugging system. After the verification is approved, it is submitted to the isolation manager.

[0066] Step S4: The debugging isolation manager reviews the boundary. The debugging isolation manager reviews the TOB handover boundary and checks for conflicts with other TOB and TOTO handover systems.

[0067] Step S5: The commissioning engineer reviews the boundaries. The commissioning engineer reviews the TOB handover boundaries and checks for conflicts between the boundaries and the work order.

[0068] Step S6: Review and submit the documents to the owner for review. The commissioning and handover engineer reviews the documents for compliance with regulations and then submits them to the owner for handover to the production engineer.

[0069] Step S7: Review the document's compliance with regulations and distribute it for review. The owner's handover engineer reviews the document's completeness and, after review, distributes it to the TOB boundary receiving department's system head and operations isolation manager for review. If a return is required, fill in the review comments and return it to the commissioning handover engineer, who will then organize the commissioning system head to make revisions. Step S8: Review and coordinate internal departmental review. The receiving department's contact person reviews the TOB handover documents, and then submits them to the receiving department's system manager and operations isolation manager for review.

[0070] Step S9: Review the TOB document. The receiving department's system head reviews the TOB handover document. If it needs to be returned, it is returned to the commissioning handover engineer, who then organizes the commissioning system head to make modifications. After the operation isolation manager reviews that the TOB boundaries are qualified and the receiving department's system head agrees, an on-site joint inspection can be organized. After agreeing to the joint inspection, click "Agree to Joint Inspection" and provide feedback to the commissioning handover engineer.

[0071] Step S10: Review TOB Boundaries. The Isolation Manager reviews the TOB boundaries. If a return is necessary, the review comments are filled out and the boundary is returned to the Debugging and Transfer Engineer, who then organizes the Debugging System Manager to make modifications. Once the review is passed, feedback is sent to the receiving department's system manager confirming that the TOB boundaries are acceptable.

[0072] Step S11: Joint Inspection Notification and On-site Inspection. The commissioning and handover engineer organizes the TOB joint inspection and issues a joint inspection notification. The system must have the function of sending joint inspection information via email, and the commissioning and handover engineer can customize the receiving group.

[0073] Step S12: Classification of Joint Inspection Comments into Category I / II. The commissioning and handover engineer organizes the commissioning system manager and joint inspection personnel offline to classify the joint inspection comments into Category I / II.

[0074] Step S13: Input of Joint Inspection Comments. After completing the on-site joint inspection, determine the joint inspection comments, classify them, and then have the person in charge of the commissioning system input them into the system. The latest completion time for each joint inspection comment needs to be specified.

[0075] Step S14: Application for closure completed after processing of joint inspection comments. After the person in charge of debugging the system has processed the joint inspection comments related to the TOB boundary, they submit a confirmation from the person who proposed the joint inspection comments that Category I items can be closed. For Category I items that cannot be processed, it is confirmed whether the process can be changed from Category I to Category II.

[0076] Step S15: The person who submitted the joint inspection opinion confirms that a Category I item can be closed or transferred to a Category II item.

[0077] Step S16: Transition from Category I to Category II Items. If, for some reason, it is impossible to eliminate Category I items in the joint inspection, then the transition from Category I to Category II items will proceed.

[0078] In step S17, the system automatically determines that one type of item has been processed, which serves as a prerequisite for handover.

[0079] Step S18, Confirmation of handover conditions. The commissioning and handover engineer confirms the EESR document signature and that Category I items have been processed, meeting the handover signing conditions, and submits a handover approval request.

[0080] Step S19, Debugging Approval TOB Handover. The head of the debugging department or authorized person approves the TOB handover.

[0081] Step S20, Confirmation of Transfer Conditions. The owner's transfer engineer confirms whether the TOB meets the conditions. If it does, the transfer is submitted to the head of the operations department for approval and acceptance. If the conditions are not met, the TOB is returned to the commissioning and transfer engineer.

[0082] Step S21, Approval of TOB Acceptance. The owner's operations department head or authorized person approves the TOB acceptance and generates the TOB handover certificate and handover document package. Step S22: Issue the TOB Isolation Operation Order. The isolation manager issues the isolation operation order.

[0083] Step S23: Implement TOB isolation on-site. The person in charge of the receiving department's system receives the isolation operation form, goes to the site to implement the isolation, and then returns the isolation operation form to the isolation office.

[0084] Step S24: Confirm TOB site isolation is complete. The isolation manager confirms isolation is complete and sends a signal to the handover engineer to send a handover notification.

[0085] Step S25: Issue the TOB handover notice. The commissioning and handover engineer issues the TOB handover notice, and the person in charge of commissioning the system posts the handover notice on-site.

[0086] Step S26: Transfer the remaining TOB boundary-related joint inspection opinions to legacy item management. After confirmation of handover, the TOB boundary-related Category II joint inspection opinions will be transferred to TOB legacy item management.

[0087] The following detailed description of the method of this application is based on a specific embodiment of the isolation and transfer of circulating water system equipment of a nuclear power plant unit under a general contracting model.

[0088] First, after the installation of the circulating water system equipment is completed, the contractor compiles an EESR (Environmentally, Technically, and Sequential) document package. This package includes installation drawings, construction inspection records, material certificates, and other documents for the circulating water pumps, pipes, valves, and other equipment. The contractor and commissioning party jointly review the document package. Once both parties confirm that the circulating water pump installation locations conform to the design drawings, the pipe welding quality meets standards, and the valves operate flexibly, they sign the EESR document package, and the circulating water system is then handed over by the contractor to the commissioning party.

[0089] Secondly, the TOB handover implementation is carried out. This process includes the following steps: The first step is for the commissioning planning engineer to enter the TOB handover plan for the circulating water system and remind the person in charge of commissioning the system to prepare the handover application documents.

[0090] The second step is for the person in charge of commissioning the system to create a TOB application, enter a file package containing the TOB boundary list of the circulating water system (clearly defining the scope from the circulating water pump room to the plant boundary), isolation requirements (closing all valves within the boundary and cutting off relevant power supplies), and the TOB boundary diagram, and submit it for approval.

[0091] The third step is for the team leader to verify the file package and confirm that the boundary list is consistent with the actual system before submitting it to the debugging isolation manager.

[0092] The fourth step involves the isolation manager reviewing the boundary and discovering that the boundary intersects with the already TOB-connected cooling water system via pipes. The manager requests that the boundary range be adjusted, and the person in charge of the debugging system modifies and resubmits the changes.

[0093] The fifth step is for the commissioning engineer to review the boundaries and work order, and submit the work order to the commissioning handover engineer after confirming that there are no conflicts.

[0094] Step 6: After the commissioning and handover engineer reviews the documents for compliance, they are submitted to the owner's handover and production acceptance engineer. After the owner's handover and production acceptance engineer reviews the documents for completeness, they are distributed to the system head and operation isolation manager of the receiving department (operations department).

[0095] The seventh step involves the operations department's contact person and the system manager reviewing the data in turn, and the operations isolation manager approving the joint inspection after confirming that the boundaries are acceptable.

[0096] Step 8: The commissioning and handover engineer organizes a joint inspection, customizes the receiving group (including commissioning, operation, and owner's representatives) and sends an email notification. The on-site joint inspection found that there was one valve with missing markings (Category 1 item) and two pipelines with incomplete insulation (Category 2 item).

[0097] Step 9: The commissioning and handover engineer organizes personnel to classify the types of comments, and the person in charge of the commissioning system enters the comments (class I comments must be completed within 3 days, and class II comments within 7 days). After completing the supplementary valve labeling within 3 days, the comments are submitted to the person who proposed the joint inspection for confirmation.

[0098] Step 10: The commissioning and handover engineer confirms the EESR signature and the completion of Category I items, submits a handover approval request, and generates a TOB certificate after approval by the head of the commissioning department, the owner's handover engineer, and the head of the owner's operations department.

[0099] Step 11: The Operations Isolation Manager issues an Isolation Operation Order. After receiving the order, the Operations Department System Manager closes the valves within the boundary and cuts off the power supply on-site. Once the operation is completed, the operation order is returned.

[0100] Step 12: The Operation Isolation Manager confirms the isolation is complete and reports back to the Commissioning and Handover Engineer. The Commissioning and Handover Engineer issues a handover notice and posts it on-site, while transferring the two pipeline insulation issues to TOB legacy management.

[0101] Then, after the TOM (Transfer of Management) system completes individual unit commissioning (testing that the circulating water pump head and flow rate meet the standards) and the rotating equipment undergoes a live-line test run with media (the pump runs continuously for 48 hours with normal temperature and vibration), the person in charge of the test verifies the commissioning results, confirms that the technical standards are met, and initiates a TOM application. The maintenance department reviews the application and commissioning report, signs the TOM certificate, and the system maintenance responsibility is transferred to the maintenance department. The maintenance department establishes an equipment maintenance log and develops a daily inspection plan.

[0102] Finally, after the TOTO handover and commissioning of the circulating water system are completed, the test supervisor evaluates the system's operating parameters (stable inlet and outlet water temperatures and pressures), functional integrity (automatic flow adjustment based on unit load), and stability (continuous operation for one month without failure). If the evaluation meets the standards, a TOTO application is initiated. The operations management department reviews and approves the application and signs the TOTO certificate. Temporary operation management responsibility for the system is then transferred to the operations management department, which operates the system according to the temporary operating procedures to prepare for grid connection and power generation.

[0103] To achieve the above embodiments, this application also proposes a nuclear power plant system equipment isolation and handover system suitable for power plant commissioning. Figure 4 This is a schematic diagram of the structure of a nuclear power plant system equipment isolation and handover system suitable for power plant commissioning, as proposed in an embodiment of this application. Figure 4 As shown, the system includes: The handover module 100 is used to transfer the system equipment from the construction party to the commissioning department after the installation of the nuclear power plant system equipment is completed by signing the Installation Completion Status Report (EESR) document package. The EESR document package includes all construction content on the construction site.

[0104] The debugging module 200 is used to define the isolation boundary of the debugging area for system equipment and initiate an isolation transfer (TOB) application. After the TOB application is approved and the TOB certificate is signed, a TOB isolation area is established according to the isolation boundary, and various debugging tests are carried out in the TOB isolation area.

[0105] The first transfer module 300 is used to initiate a maintenance transfer to maintenance (TOM) application in response to the completion of the isolation transfer (TOB) of the system equipment and the completion of individual commissioning and the test rotation of the rotating equipment with electricity and medium. After signing the TOM certificate, the maintenance task of the system equipment is transferred from the commissioning department to the maintenance department.

[0106] The second transfer module 400 is used to initiate a temporary operation transfer to TOTO application in response to the system equipment having been debugged and having long-term operation capability, and after signing the TOTO certificate, to transfer the temporary operation management task of the system equipment from the debugging department to the operation management department.
