ASN's annual reports

Every year, this report presents the state of nuclear safety and radiation protection in France. It also presents all ASN actions performed during the past year to supervise and improve the safety of French civil nuclear facilities and of the transport of radioactive materials, and to check and minimise exposure of workers, patients, the public and the environment to ionising radiation.
Since 2004, via the "ASN multiyear strategic plan", it also presents ASN's orientations and goals for the coming 3-year period.
This report, which is the fruit of collective analysis and synthesis work, in which all ASN entities take part, provides an annual record of the changes and difficulties encountered, in both the technical and organisational spheres, within the companies and organisations subject to supervision. It also widens the scope of the debate to include nuclear safety and radiation protection projects and prospects.
The report and its summary are sent to many of ASN's partners abroad, notably the nuclear safety authorities of various countries. Since 1996, the report has been translated into English to further exchanges between nuclear safety authorities and inform all foreign stakeholders in the nuclear safety and radiation protection sector.

ASN Report on the state of nuclear safety and radiation protection in France in 2022

In 2022, the level of safety in the nuclear installations remained at a satisfactory level, as did radiation protection in the industrial, medical and radioactive substances transport sectors.
However, the year 2022 was marked by issues in the nuclear installations hitherto never encountered, as well as by a period of intense heatwave.
These events once again highlighted the need to maintain safety margins and to anticipate the challenges ahead, including dealing with exceptional situations linked to climate change.

ASN Report on the state of nuclear safety and radiation protection in France in 2021

In 2021, the safety of nuclear facilities and radiation protection in the medical, industrial and radioactive substances transport sectors remained at a satisfactory level, in line with the level observed in 2021.
What are most striking about 2021, in particular its second part, are the industrial vulnerabilities affecting all nuclear facilities and the debate concerning energy policy choices and the position of nuclear power in these choices.

ASN Report on the state of nuclear safety and radiation protection in France in 2020

The year 2020 was profoundly marked by the crisis caused by the Covid-19 pandemic. ASN considers that the level of nuclear safety and radiation protection achieved remained satisfactory and that those responsible for nuclear activities were able to adapt and cope with the situation.
In early 2021, the health crisis is still not over and prudence is required with regard to the lessons to be learned, in an uncertain and changing context.
ASN considers that this situation raises systemic questions which could apply, in the same terms, in the event of a nuclear crisis. This notably concerns trust in scientific expertise and in the authorities by the population and the conditions determining the acceptability of the restrictive population protection measures.
More generally, ASN considers that the first analyses of the problems encountered during this health crisis confirm the absolute need, which it has regularly underlined, to strengthen the culture of anticipation and precaution among all those concerned by nuclear matters.

Regulatory Updates Newsletter

Regulatory Updates is the monthly newsletter of the French Nuclear Safety Authority. It keeps you informed on ASN national and international activities as well as on the current events of the nuclear installations under its control.
It is regularly distributed to ASN counterparts at international meetings.
You can find the latest copy of Regulatory Updates and its publication history in this section.

Les cahiers de l’ASN brochure

The first issue of Les cahiers de l’ASN brochure was published in September 2018. This new collection is part of a pedagogical information approach on topics related to nuclear safety and radiation protection.
This brochure is also distributed in forums, trade shows, public meetings and among stakeholders.

French National Plan for the Management of Radioactive Materials and Waste for 2013-2015

The National Radioactive Materials and Waste Management Plan (PNGMDR) is a key tool in ensuring the long-term implementation of the principles laid down in the Programme Act of 28th June 2006 concerning the sustainable management of radioactive materials and waste. It aims primarily to produce a regular picture of radioactive substances management policy, to evaluate new requirements and to determine the objectives to be met in the future, particularly with regard to studies and research. Its validity was confirmed at a European level, by the adoption on 19th July 2011 of the directive establishing a community framework for the responsible and safe management of spent fuel and radioactive waste.
