ASNR'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 2016

On the whole, 2016 was satisfactory despite a worrying context.
The year was marked by the detection of a serious generic anomaly. Eighteen EDF reactors were potentially affected by excess carbon in the steel used in the manufacture of the steam generators. Specific checks were ordered by ASN on all these reactors and five of them had to be shut down early.

ASN Report on the state of nuclear safety and radiation protection in France in 2015

2015 is similar to previous years: the nuclear safety and radiation protection situation is on the whole satisfactory. The operating safety of the nuclear installations has in particular been maintained at a good level, although radiation protection requires particular vigilance, especially in the medical field, with about ten level 2 incidents occurring in 2015. However, this positive evaluation for 2015 should be moderated as the context is a worrying one, with significant concerns for the future.

Les cahiers de l’ASNR brochure

The first issue of Les cahiers de l’ASNR 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.

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.

Les cahiers de l'ASN #06 - Radioactive Waste

Nuclear power is a major source of energy in a large number of countries. In France, it accounts for more than 70% of all the electricity produced. Although nuclear production of electricity emits very little in terms of greenhouse gases, it does have other environmental implications, such as radioactive waste.

Les cahiers de l'ASN #05 - 1300 MWe Nuclear Reactors Operation beyond 40 years

In France, 20 nuclear reactors with a power of 1,300 MWe, spread over 8 sites, will reach their 40th year of operation within the next few years. On this occasion, these reactors will undergo a periodic safety review*, which will be able to define the conditions that will determine their continued operation for a further 10 years.
