Reactor Regulation

  • The Safety review for NPP, in general, consists of two steps, the Construction Permit (CP) and Operating License (OL). A detailed licensing procedure for NPP is summarized below.
  • Review for SDA(Standard Design Approval)
    • For the standard design of NPPs which have enhanced level of safety, the regulatory effectiveness has been improved by setting up a new licensing system, i.e., the Standard Design Approval (SDA) System. The SDA system ensures the validation of approved standard design without imposing additional regulatory requirements during a certain period of time by the law and basically excludes safety reviews for the portions of NPPs which refer to approved standard design.
  • Review for ESA(Early Site Approval)
    • In order to start a limited construction work on a proposed site before the CP is issued, an applicant may apply for an early site approval. The applicant shall file an application accompanied by a site survey report and a radiological environmental report. The objectives of the ESA are to evaluate the adequacy of the proposed nuclear site and the radiological impacts on the environment surrounding the nuclear installation.
  • Review for CP(Construction Permit)
    • The safety review on the application for a CP is conducted to confirm that the site and the preliminary design of the nuclear installation are in conformity with the relevant regulatory requirements and technical guidelines. It includes safety reviews on the principles and concepts of reactor facility design, the implementation of regulatory criteria in due course, the evaluation of environmental effects resulting from the construction, and a proposal for minimizing those effects.
      The applicant for a CP for nuclear installation shall submit an application accompanied by a radiological environmental report, a preliminary SAR, and a construction quality assurance plan. The radiological environmental report to be submitted as part of the application for a CP and also for early site approval should contain the public's opinion, if necessary, brought up by public hearing conducted in the communities surrounding the nuclear installation.
  • Safety Review for OL(Operating License)
    • The safety review on the application for an OL is conducted to confirm that the final design of the nuclear installation is in conformity with the relevant regulatory requirements and technical guidelines and that the nuclear installation may continue to operate throughout its lifetime.
      The applicant for an OL for a nuclear installation shall submit an application accompanied by technical specifications for operation, a final SAR, a quality assurance plan for operation, and a radiological environmental report.
      The approval for an amendment to the OL follows the same procedures as the application for an OL. A safety review is to be conducted for the parts whose safety is affected or may be affected by the amendment to the OL.
  • Periodic Safety Reviews(PSR)
    • The periodic safety reviews (PSRs) for operating nuclear power plants are conducted at 10 year intervals in order to complement their weak points caused by ageing degradation of components and to assure safety to be equivalent to that of newly constructed plants.
  • Continued Operation
    • Regarding the continued operation beyond the original design life, comprehensive safety assessment of the installation is to be carried out. For the licensing renewal, two additional review items such as the lifetime evaluation for major components and the radiological environmental impact assessment are to be incorporated into the periodic safety review(PSR).
      Application should be made 2 to 5 years before the end of design life for additional 10 years of operation.
