2 GENERAL PRESENTATION OF CODES
2.3 Background Information on JSME
Historically, detailed technical rules and requirements on the design and construction activities for nuclear power plants in Japan were provided by the government as part of the government regulation system such as MITI Ordinance No. 62 and Notification No. 501. During the late 1990s, shortly after the WTO/TBT agreement came into in effect in 1994, there evolved discussions that the government regulation should be performance-based and that codes and standards of Standards Development Organizations (SDOs) should be applied as detailed technical codes (Reference [4]).
The Committee on Power Generation Facility Code was established within the Japan Society of Mechanical Engineers (JSME) in October 1997 to provide technically sound codes and standards to protect people’s safety from industrial hazards and to promote industry development and competitiveness. Behind the scene, a consensus was reached between the regulator and the industry that the regulatory body would endorse and apply SDO codes and standards for their regulation of nuclear power plants in Japan.
Under the main committee, there are four subcommittees that include thermal power, nuclear power, fusion power and materials, as are shown in Figure 6. The subcommittee on nuclear power is responsible for developing, maintaining, and revising JSME nuclear codes and standards, and has in its under-tier 12 subgroups such as design and construction, materials, fitness for service, and so on.
The organization of the subcommittee on nuclear power is shown in Figure 7. Each of these subgroups is responsible for a code book and many of these subgroups have several working groups.
As of today, a total of about 350 volunteers are actively committed to the JSME Codes and standards development and maintenance activities. These volunteers come from various sectors. These include industry (utilities, nuclear systems, component suppliers, and steel makers), laboratories and research institutes, university academia, government organizations, and regulatory agencies.
Since its foundation in 1997, the committee has issued a number of codes in the fields of thermal power, nuclear power, and fusion power. The latest editions of the JSME nuclear codes are listed in Figure 8 and the standards referenced in the JSME Code are listed in Figure 9. Note that the codes for spent fuel transport/storage casks and for spent fuel reprocessing facilities are included in JSME nuclear codes. Beside these code books, a number of code cases have been issued.
The first nuclear code published by JSME was JSME S NA1-2000, Rules on Fitness-for-Service for NPPs, which was a counterpart of ASME Section XI. The first edition of Rules on Design and Construction for NPPs, which is a counterpart of ASME Section III, was published in 2001. Since then, the JSME nuclear code editions have basically been published every three to five years.
Between these editions, addenda have been issued generally on a yearly basis.
As was mentioned earlier, these JSME nuclear codes are subjected to technical evaluation conducted by the Japan Nuclear Energy Organization (JNES)1, and then endorsed by the Nuclear and Industry Safety Agency (NISA).
Among these nuclear codes, JSME S NA1-2008, Rules on Fitness-for-Service for NPPs;
JSME S NB1-2007, Rules on Welding for NPPs; and JSME S NC1-2007, Rules on Design and Construction for NPPs, Div. 1 LWRs, have been endorsed by NISA, the government regulatory body, and applied to the regulation of LWR nuclear activities of design, construction, maintenance, and repair.
