Abstract
Description
Technical Field
[0001] This invention relates to the field of nuclear power plant digital technology, and in particular to a method for generating digital RP certificates for nuclear power plants. Background Technology
[0002] The traditional method of using a radiation control area pass (RP pass) is as follows: all personnel entering the radiation control area of a nuclear power plant must obtain a radiation control area pass. Personnel identification and verification are carried out by manually scanning the QR code on the RP pass before entering the radiation control area.
[0003] Currently, applying for a radiation control area pass requires first submitting an application in the Personal Dosimetry Management System (PDMIS). After approval, staff must go to the issuing office for four steps: identity verification, whole-body counter (WBC) irradiation monitoring, RP pass collection, and information confirmation authorization activation. Once the RP pass is issued, staff can enter the radiation control area through either the reader at the health entrance of the radiation control area (reading the RP pass QR code) or by manually entering their 8-digit employee code for identification and verification.
[0004] Long-term practical experience has revealed that the existing certificate issuance process suffers from problems such as lengthy processing times, numerous manual interventions, high risk of human error, low efficiency, limited information access, and the inability to process certificates outside of working hours. Furthermore, using a reader to scan the certificate's QR code or manually entering personnel codes poses risks of malicious identity theft, accidental entry into radiation control areas using someone else's identity, and the carrying of physical RP certificates could potentially create foreign object hazards within the nuclear island. Summary of the Invention
[0005] The purpose of this invention is to provide a method for generating digital RP certificates for nuclear power plants, thereby improving the management level of radiation control zone access permits.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] On one hand, the present invention provides a method for generating a digital RP certificate for a nuclear power plant, comprising:
[0008] Step 1: Digitize key information to generate a digital identity;
[0009] Step 2: Bind the key information from Step 1 to generate a digital RP certificate;
[0010] Step 3: Register the digital identity of the digital RP certificate on the blockchain;
[0011] Step 4: The user's facial biometric information is bound to the digital RP certificate, and the digital RP certificate is used by facial scanning.
[0012] In some embodiments, step 1 specifically includes:
[0013] Step 1.1: Encrypt the applicant's ID number and facial information to generate an encrypted ASCII string;
[0014] Step 1.2: Encrypt the approval confirmation information, the approver's work ID number, and the approver's facial information to generate an encrypted ASCII string;
[0015] Step 1.3: Encrypt the approved full-body counter monitoring data and the work permit number and facial information of the full-body counter approver to generate an encrypted ASCII string;
[0016] Step 1.4: Encrypt the authorization result, the operator's work ID number, and facial information to generate an encrypted ASCII string.
[0017] In some embodiments, key information includes personal identity, approval results of the personal dose management system application process, whole-body counter monitoring data, and information confirmation authorization results.
[0018] In some embodiments, step 2 specifically includes:
[0019] Step 2.1: Generate a unique identifier;
[0020] Step 2.2: Bind application records;
[0021] Step 2.3: Encrypt the digital identity of the individual, the application process approval result of the personal dose management system, the whole-body counter monitoring data, and the information confirmation authorization result by using elliptic curves;
[0022] Step 2.4: Generate the encrypted digital RP certificate.
[0023] In some embodiments, the applicant's personal digital identity is used as the unique identifier of the person.
[0024] In some embodiments, each login record contains a digital identity consisting of an encrypted numeric string representing the individual's identity, an encrypted numeric string representing the approval result of the personal dose management system application process, an encrypted numeric string representing WBC monitoring data, and an encrypted numeric string representing the information confirmation authorization result.
[0025] In some embodiments, the digital RP certificate and metadata generated in step 2, along with a unique identifier, are registered on the blockchain.
[0026] In some embodiments, metadata includes creator, creation date, person's facial biometric information, and full-body counter history data.
[0027] On the other hand, the present invention provides a computer device including a memory and a processor, wherein the memory stores computer-readable instructions, and the processor executes the computer-readable instructions to implement the steps of the nuclear power plant digital RP certificate generation method.
[0028] On the other hand, the present invention provides a computer-readable storage medium storing computer-readable instructions, which, when executed, implement the steps of the nuclear power plant digital RP certificate generation method.
[0029] Compared with existing technologies, the method for generating digital RP certificates for nuclear power plants provided by this invention has the following advantages:
[0030] Existing technologies involve reading QR codes on documents using physical readers or manually entering personnel codes. In various work ticket modes, manual input is often required, frequently leading to errors in the input information and affecting passage efficiency. This is especially true during major maintenance periods, which can easily cause passage congestion. This invention greatly simplifies this process. Passage can be completed quickly simply by authenticating with a facial recognition device, significantly reducing errors in the input information and improving passage efficiency.
[0031] Under current methods, carrying a physical RP certificate may pose a risk of foreign objects entering the nuclear island. This invention reduces the risk of foreign objects entering the nuclear island by replacing the physical certificate with a digital RP certificate.
[0032] Under the existing working model, there is a risk that someone may maliciously impersonate another person and enter the radiation control area. This invention eliminates this risk from the system level. Attached Figure Description
[0033] To more clearly illustrate the technical solution of the present invention, the accompanying drawings used in the technical description will be briefly introduced below.
[0034] Figure 1 The flowchart illustrates the method for generating digital RP certificates for nuclear power plants provided by this invention. Detailed Implementation
[0035] The following detailed description provides further details on specific implementation methods.
[0036] This invention uses digital certificate technology to create digital radiation control zone passes (digital RP certificates), thereby replacing the use of physical RP certificates. For example... Figure 1 As shown, the present invention provides a method for generating a digital RP certificate for a nuclear power plant, comprising:
[0037] Step 1: Digitize key information to generate a digital identity.
[0038] Key information includes personal identification (ID number and facial information), approval results of the personal dosing management system application process, whole-body counter monitoring data, and information confirmation authorization results. The digital identity of these four pieces of information is used as proof of their uniqueness and authenticity through the digital RP certificate. Step 1 specifically includes:
[0039] Step 1.1: Digitizing Personal Identity. The applicant's ID number and facial information are encrypted and calculated to generate an encrypted ASCII string.
[0040] The application system's software functions obtain the applicant's ID number and facial information; the applicant's ID number and facial information are then encrypted using a method that is not disclosed, generating an encrypted ASCII string. The applicant's digitized identity information is illustrated below:
[0041] a1 = f(applicant's identity, applicant's facial data).
[0042] Step 1.2: Digitizing the Approval Result of the Personal Dosing Management System Application Process. The approval confirmation information, the approver's work ID number, and the approver's facial information are encrypted and calculated to generate an encrypted ASCII string. The digitization of the personal dosing management system application process approval result is illustrated below:
[0043] a2 = f(approval result, approver's work ID number, approver's facial data).
[0044] Step 1.3: Digitization of Full-Body Counter Monitoring Data. The approved full-body counter monitoring data, along with the approver's work ID number and facial information, are encrypted and processed to generate an encrypted ASCII string. An example of full-body counter monitoring data digitization is shown below:
[0045] a3 = f(WBC data, WBC approver's work ID number, WBC approver's face data).
[0046] Step 1.4: Digitizing the Information Confirmation and Authorization Result. The information confirmation and authorization result, the operator's work ID number, and facial information are encrypted and calculated to generate an encrypted ASCII string. An example of the digitized information confirmation and authorization result is shown below:
[0047] a4 = f(Information confirmation result, information confirmation person's face data).
[0048] Step 2: Bind the four pieces of information from Step 1 to generate a digital RP certificate. Step 2 specifically includes:
[0049] Step 2.1: Generate a unique identifier. The applicant's personal digital identity serves as the unique identifier for the individual.
[0050] Step 2.2: Bind application records. Each login record contains four types of digital identity information: encrypted numeric strings containing personal identification (ID number and facial information), encrypted numeric strings containing the approval result of the personal dose management system application process, encrypted numeric strings containing WBC monitoring data, and encrypted numeric strings containing the information confirmation authorization result.
[0051] Step 2.3: Data Encryption. Elliptic Curve Cryptography (ECC) is used to encrypt and calculate the digital identities of four pieces of information: personal identification (ID number and facial information), approval results of the personal dose management system application process, whole-body counter monitoring data, and information confirmation authorization results.
[0052] Step 2.4: Generate the encrypted digital RP certificate. The calculation and generation of the digital RP certificate is illustrated below:
[0053] DigiRP = ECC(a1,a2,a3,a4).
[0054] Step 3: Register the digital identity of the digital RP certificate on the blockchain.
[0055] The digital RP certificate and metadata (including creator, creation date, facial biometric information, and historical data from the full-body counter) generated in step 2, along with a unique identifier, are registered on the blockchain. This digital RP certificate becomes an immutable and tamper-proof digital asset. Furthermore, because it is recorded on the blockchain, the historical information related to the digital RP certificate, through the introduction of blockchain, possesses the property of being queryable but not modifiable. This makes it a reliable way to establish uniqueness and authenticity in the digital realm.
[0056] Step 4: The user's facial biometric information is bound to the digital RP certificate, and the digital RP certificate is used through facial scanning.
[0057] In addition, the present invention also provides a computer device, including a memory and a processor, wherein the memory stores computer-readable instructions, and the processor executes the computer-readable instructions to implement the steps of the above-described method for generating a digital RP certificate for a nuclear power plant.
[0058] In addition, the present invention provides a computer-readable storage medium storing computer-readable instructions, which, when executed, implement the steps of the above-described method for generating a digital RP certificate for a nuclear power plant.
[0059] Computer-readable media, including both permanent and non-permanent, removable and non-removable media, can store information using any method or technology. Information can be computer-readable instructions, data structures, program modules, or other data. Examples of computer storage media include, but are not limited to, phase-change memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), other types of random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technologies, CD-ROM, digital versatile optical disc (DVD) or other optical storage, magnetic tape, magnetic magnetic disk storage or other magnetic storage devices, or any other non-transfer medium that can be used to store information accessible by a computing device.
[0060] Therefore, this invention digitizes personal identification information, the application process and approval results of the personal dosage management system, whole-body counter monitoring data, and information confirmation and authorization results. This invention provides a method for binding digital RP certificates; and a method for registering on the blockchain and generating a unique identifier (containing historical whole-body counter data).
[0061] This invention includes historical full-body counter data and supports a built-in function to query an individual's historical full-body counter data. The user's facial biometric information is used as the public key, in conjunction with a digital RP certificate.
[0062] This invention does not require changes to the existing physical RP (Radiation Protection) certificate workflow. The RP certificate application involves almost all personnel working within radiation control areas, including full-time employees, maintenance service providers, contractors, various workers during overhauls, and government regulatory personnel. Changing the current workflow would affect almost all of these personnel.
[0063] While applying this invention, the existing workflow remains unchanged, offering several advantages:
[0064] (1) Nuclear power plants can avoid the complexity of reapplying for licenses or undergoing extensive regulatory reviews (such as the upgrade of FSAR), and any technical improvements that do not change existing operating procedures are more likely to pass regulatory reviews;
[0065] (2) Keep the work procedures of various other business departments of the power plant involved in the RP certificate application unchanged as much as possible; following the existing operating procedures can reduce the risk of human error in critical operations caused by the introduction of new technologies (new procedures) and reduce the potential risk of shutdown; this is especially important for nuclear power plants, because the consequences of errors can be very serious.
[0066] (3) The various training systems and simulators currently used in the power plant do not require changes to the standard operating procedures;
[0067] (4) Maintaining process consistency while introducing technological innovation means that the above-mentioned personnel do not need to spend extra time learning new processes, reducing negative feedback and evaluations from users on new technologies and RP management departments, thereby achieving a smooth transition to new technologies.
[0068] This invention improves the reliability and immutability of radiation dose data related to RP certificates by combining digital encryption technology and blockchain technology.
[0069] By using blockchain technology, this invention allows direct querying of historical dose data through RP certificate number and personnel identity information, increasing the ways to obtain personnel dose information and greatly improving the convenience of obtaining historical data.
[0070] The key aspect of this invention is the reduction of manual intervention, which systematically lowers the risk of human error in the entire certificate issuance process.
[0071] The key steps of this invention are all completed automatically by the system, which can also overcome the shortcomings of the current certificate processing process, such as long processing time and low work efficiency.
[0072] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
