ASME Section III has been the most important Code for the design and construction of nuclear components for over 30 years in Korea. During that time, some difficulties have been recognized in compliance with the Code due to the differences in industrial practices and regulatory system between Korea and the U.S. In case of NCA (General Requirements for Division 1 and 2), the administrative and procedural requirements have been applied as modified to suit domestic industry practices. For technical aspects, supplemental requirements have been added to ASME Code in order to satisfy regulatory guides. Preheating and PWHT requirements of ASME Section III are slightly different from those of ASME B 31.1. The differences are discussed in this presentation. With the issuance of MOST (Ministry of Science & Technology) notice 96-32 in 1996 regarding KEPIC (Korea Electric Power Industry Code) application, KEPIC MN has been used in selected documents instead of ASME Sec. III. Ulchin 5&6 is the first project that applied to KEPIC. The application of KEPIC - MN has been gradually expanding to the subsequent nuclear projects. For consistent use of KEPIC, some measures for foreign vendors’ application of KEPIC should be considered.

The development of low-carbon electric power industry plays a vital role in sustainable economic development due to the supporting role of electricity in the Gross Domestic Product GDP. The electric carbon productivity indicator is introduced to investigate the provincial economic development and electric industry-related indicators. The refined Laspeyres decomposition technique is adopted to decompose provincial economic change into the quantitative influence of CO2 emission, electric carbon productivity, and emission structure for the first-stage decomposition; the electric carbon productivity change is sub-decomposed into the influence of factors such as electricity-economic productivity, electricity import-export, and generation carbon efficiency. Through decomposition analysis for the research period of 2005 to 2015, scientific and reasonable suggestions are made for improvement of electric carbon productivity and provincial economic development: (1) The main obstacle to electric carbon productivity improvement is emissions from the power industry. (2) There is interaction between the green economic development mode and the low-carbon electric power industry. In others words, provincial future economy development mode formulation should consider not only economic and industrial factors but also power industry factors. (3) The issue of electric carbon productivity improvement and regional development mode is partially consistent with geographic locations, which is a comprehensive effect of economy level, power industry, energy resources, technological development level, environmental awareness, etc. (4) Due to the existence of regional protection, provincial local incentives should be promulgated to break the GDP-driven development mode to realize coordination among the economy, power industry, and the environment.
