Description

Technical Field

[0001] The present application relates to the technical field of nuclear power plant equipment, and in particular to a method and device for identifying safety-related characteristics of general industrial products used in nuclear power plant safety systems. Background Art

[0002] Safety systems, critical to nuclear power plant safety, are used to ensure safe reactor shutdown under all operating conditions, remove heat from the core, and limit the consequences of anticipated operational events and accident conditions. These systems perform safety functions. In safety system applications, only certain equipment, such as safety-grade cables, can be purchased as safety-rated products. Most products cannot be purchased as safety-rated products and must be purchased as general industrial products. However, these products must be identified for safety-related characteristics that affect their intended safety functions and then verified for compliance before they can be used in safety systems.

[0003] Conventional nuclear power plants do not identify safety-related characteristics of general industrial products in safety systems. Instead, they verify these products by integrating them into cabinets and performing environmental, seismic, and electromagnetic compatibility (EMC) tests. However, these tests do not fully cover the safety-related characteristics of general industrial products, leading to frequent batch quality issues during use. Another approach, to ensure commercial-grade quality, involves testing and verifying all design features of products upon receipt. While this approach ensures full coverage of safety-related characteristics, it significantly increases application costs. Summary of the Invention

[0050] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0051] The present application is further described in detail below with reference to specific embodiments. These embodiments should not be construed as limiting the scope of protection claimed in this application.

[0052] The following describes, with reference to the accompanying drawings, a method and apparatus for identifying safety-related characteristics of general industrial products for a nuclear power plant safety system according to an embodiment of the present application.

[0053] Figure 1 FIG. 1 is a flow chart of a method for identifying safety-related characteristics of general industrial products for a nuclear power plant safety system according to an embodiment of the present application. Figure 1 As shown, the method includes the following steps:

[0054] S1, determine whether the general industrial product is applied to the security system to perform security-level functions.

[0055] In nuclear power plant safety systems, only certain equipment, such as safety-grade cables, can be purchased as safety-grade products. Most products are not available, requiring the purchase of general industrial products. Therefore, it is necessary to first verify the general industrial products to determine whether they can be used to perform safety-grade functions within the safety system. For example, if the general industrial product can ensure safe reactor shutdown under all operating conditions, remove heat from the core, or limit the consequences of anticipated operational events and accident conditions, then it can be considered to perform safety-grade functions within the safety system.

[0056] S2: If the general industrial product is applied to the security system to perform a security-level function, then design information of the general industrial product is obtained.

[0057] In one embodiment of the present application, design information can be extracted from design materials provided by the product manufacturer. The design materials may include product manuals, technical specifications, etc. These design materials typically contain design information for general industrial products, and the design information for the general industrial products can be obtained from them.

[0058] In addition, some industry-related regulations and standard requirements also stipulate the design information of some general industrial products, and this design information can also be obtained from the relevant regulations and standard requirements.

[0059] S3, sort out the design characteristics of general industrial products based on the design information.

[0060] After obtaining the design information, the design information can be sorted to obtain the design characteristics of general industrial products. Design characteristics may include physical characteristics, performance characteristics, and reliability characteristics. Among them, physical characteristics specifically include the physical characteristics of the product, such as structure, size, etc. Performance characteristics specifically include the functions of the product and function-related performance, as well as the ability to perform functions under expected environmental conditions (such as earthquake, temperature, humidity, radiation, and electromagnetic compatibility). Reliability characteristics (or development process characteristics) are unique characteristics of digital equipment, mainly digital equipment life cycle process control characteristics, such as configuration management, traceability, etc.

[0061] S4, analyzing the design characteristics of general industrial products based on predetermined safety functions, and obtaining safety-related characteristics of the general industrial products.

[0062] Specifically, through Failure Mode and Effects Analysis (FMEA), the design characteristics of general industrial products can be analyzed to identify safety-related characteristics that affect the product's safety functions. This means analyzing and identifying design characteristics whose failure will affect the execution of safety functions. These design characteristics are considered safety-related characteristics. Overlapping characteristics can also be identified to avoid repeated verification.

[0063] In addition, S5, if the general industrial product is not applied to a safety system to perform a safety-level function, it is not necessary to identify the safety-related characteristics of the general industrial product.

[0064] The nuclear power plant safety system of the embodiment of the present application uses a method for identifying safety-related characteristics of general industrial products. By applying general industrial products to the safety system to perform safety-level functions, the design information of the general industrial products is obtained, and the design characteristics of the general industrial products are sorted out based on the design information. The design characteristics of the general industrial products are analyzed based on predetermined safety functions, and the safety-related characteristics of the general industrial products are obtained. This can ensure that the complete range of safety-related characteristics is covered, and the correctness and consistency of the identification of safety-related characteristics are guaranteed, thereby saving verification time and cost and ensuring the safety function of the safety system.

[0065] In another embodiment of the present application, Figure 2 As shown in the figure, the method for identifying safety-related characteristics of general industrial products for nuclear power plant safety systems also includes:

[0066] S6, generate a list of safety-related characteristics of general industrial products.

[0067] After obtaining the safety-related characteristics of general industrial products, a safety-related characteristics list of general industrial products can be generated, thereby providing a basis for the subsequent verification process of general industrial products.

[0068] The following describes a specific embodiment.

[0069] like Figure 3 As shown in FIG, the method for identifying safety-related characteristics of general industrial products for nuclear power plant safety systems includes the following steps:

[0070] S31, determining whether the general industrial product is a safety-level application.

[0071] Specifically, it is necessary to determine whether the general industrial product is used in a safety system to ensure safe reactor shutdown under all operating conditions, remove heat from the core, or limit the consequences of anticipated operational events and accident conditions. If so, the process proceeds to step S32; if not, the process proceeds to step S36.

[0072] S32, identifying safety functions.

[0073] Identify the specific safety functions of general industrial products in safety applications, such as reactor shutdown and dedicated safety facilities.

[0074] S33, collect product design information.

[0075] Obtain formal design information from product manufacturers, such as product manuals and technical specifications, and organize all the product's design features. In addition, supplement and improve the design features in accordance with relevant regulations and standards.

[0076] S34, Failure Mode and Effects Analysis.

[0077] All design characteristics are divided into three categories: physical characteristics, performance characteristics, and reliability characteristics. Physical characteristics include the physical features of the product, such as structure and dimensions. Performance characteristics include the product's functions and function-related performance, as well as its ability to perform functions under expected environmental conditions (such as earthquake, temperature, humidity, radiation, and electromagnetic compatibility). Reliability characteristics (or development process characteristics) are unique to digital devices and primarily address lifecycle process control characteristics, such as configuration management and traceability.

[0078] Through Failure Mode and Effects Analysis (FMEA), the relevance of all design features to their intended safety functions is identified. This means analyzing and identifying design features whose failures may affect the execution of safety functions. These design features are considered safety-related features. Overlapping features are also identified to avoid repeated verification.

[0079] Take relay as an example, Figure 4 The following table shows the information related to the identification of safety-related characteristics of relay failure mode and effect analysis. Relays are mainly used in reactor protection system shutdown and dedicated safety facility control circuits. Their safety functions include two aspects:

[0080] 1) Shutdown control function (de-energization of the relay coil and disconnection of the contacts can trigger shutdown);

[0081] 2) Special safety facility control function (when the relay coil is energized and the contacts are closed, the special safety facility can be triggered to operate).

[0082] Figure 4 The relay also displays information such as its design characteristics and their sources, failure modes, safety function impact, and whether it is a safety-related characteristic. For example, the relay's operating threshold voltage, a characteristic derived from the GB14048.4 standard, is considered safety-related because its failure mode is an excessively high operating threshold voltage, which affects the safety function.

[0083] S35, generating a safety-related feature list.

[0084] Organize the safety-related characteristics identified by the failure mode and effects analysis into Figure 5 The safety-related characteristics list shown shows the physical and performance characteristics of the relay that are determined to be safety-related.

[0085] S36, no need to identify safety-related characteristics

[0086] The method for identifying safety-related characteristics of general industrial products for a nuclear power plant safety system according to an embodiment of the present application has the following beneficial technical effects:

[0087] 1) By obtaining design information from the manufacturer and identifying design features in combination with relevant regulatory standards, the full range of safety-related features can be covered. 2) By performing failure mode and effects analysis, the correctness of safety-related feature identification can be ensured. 3) By classifying safety-related features, the consistency of safety-related features can be ensured.

[0088] In order to implement the above embodiments, the present application also proposes a device for identifying safety-related characteristics of general industrial products for a nuclear power plant safety system.

[0094] The acquisition module 62 is further configured to acquire design information from regulations and standard requirements corresponding to general industrial products.

[0095] The sorting module 63 is used to sort out the design characteristics of general industrial products based on the design information.
