Approach to the safety of third generation nuclear reactors in France

Over the last twenty years, the need to improve the safety of future reactors compared with existing reactors has been progressively recognized, at least at national level and within the European framework, with the definition of voluntarily ambitious objectives, particularly with regard to reducing the probability of core meltdown and reducing environmental emissions. This article presents the safety objectives and approach adopted for Generation III nuclear reactors in France. While there is now a broad consensus on the major safety objectives for these reactors, their implementation in terms of technical design and operating choices differs greatly depending on the manufacturer's plans. Demonstrating the ability of these projects to meet these major safety objectives is also the subject of debate. Safety requirements and approaches differ from country to country, depending on regulations and historical practices. Without calling into question the principle of national sovereignty, a harmonization of nuclear safety practices is being sought.
