Nuclear power generation facilities. Environmental fatigue evaluation method for nuclear power plants

This JNES-SS report is 'Environmental Fatigue Evaluation Guide for Nuclear Power Generation Facilities' that summarizes the results on environmental fatigue evaluation derived from the final technical results of EFT project, 'Environmental Fatigue Testing of Materials for Nuclear Power Generation Facilities'. This EFT project was advanced by commission to the Japan Power Engineering and Inspection Corporation (JAPEIC) from Ministry of International Trade and Industry (MITI) (from April 1994 to September 2003), and subsequently by subsidies to the Japan Nuclear Energy Safety Organization (JNES) from MITI (from December 2003 to March 2007). This report is to provide the final proposal of the equation to evaluate the environmental fatigue life that has been reviewed and revised, including the newest data obtained in EFT project. (J.P.N.)
