The periodic safety review (PSR) related to the third ten-yearly outage of the 900 MWe nuclear power plants was launched in 2002. This PSR will have the same main objectives as the previous PSRs related to the second ten-yearly outages of the 900 MWe and 1300 MWe nuclear power plants :
· To verify the conformity of the nuclear power plants to their current safety requirements, by means of standard safety studies valid for all the 900 MWe nuclear units and of a conformity verification performed at each 900 MWe nuclear unit;
· To enhance the 900 MWe nuclear power plants safety level taking into account more recent safety requirements.
The first step of the work consisting in defining the program of the PSR has been completed. From November 2002 technical discussions took place between the radioprotection and nuclear safety general directorate (DGSNR), IRSN and Electricité de France about the scope and objectives of the PSR. In June 2003, IRSN presented to the standing group of experts the assessment of Electricité de France PSR program proposal. This text presents the main conclusions of this assessment and of the standing group of experts meeting.
