Les Cahiers de l’ASNR #07 - 1300 MWe Nuclear Reactors

The twenty nuclear reactors with a capacity of 1,300 MWe in service today in France are approaching their 40th year of operation.
Following extensive analysis and expert assessment, as well as broad public involvement in the review process, ASNR* has reached a decision on the conditions necessary for the continued operation of the reactors, and on the safety improvements that EDF will have to implement during the periodic safety review.

As the licensee, EDF is required to carry out a periodic safety review* of each of its reactors every ten years.
During each periodic safety review, the condition of the facility is checked, its compliance with applicable rules is verified, and safety improvements are implemented, taking into account the requirements that apply to the most recent facilities in France and abroad.

As the independent authority tasked with monitoring nuclear safety, ASNR is responsible for analysing the studies carried out by the licensee and for defining the conditions for continued operation of the reactors. This “Cahier de l’ASNR” brochure presents ASNR’s conclusions on the fourth periodic safety review of the 1,300 MWe reactors with regard to areas such as component ageing, resistance to natural hazards (earthquakes, floods and fires), and safety enhancements to the spent fuel pools.
