Osiris and Isis experimental reactors may continue to operate
In its assessment of 27 May 2011 (2011-AV-0121), ASN determined that the Osiris reactor can continue operation until 2015, at which time the reactor should be shut down in compliance with ASN Commission decision 2008-DC-0013 of 16 September 2008. For its part, the Isis reactor can continue to operate for an additional ten years from the date on which its most recent safety review file was submitted, i.e., until 2019. The two experimental reactors constitute basic nuclear installation 40 operated by the CEA in the municipality of Saclay (Essonne).

CSA: ASN issues its opinion concerning the methodologies adopted by the operators
By the resolutions taken on 5 May 2011, the French Nuclear Safety Authority (Autorité de sûreté nucléaire – ASN) has required all operators of relevant basic nuclear installations, including AREVA, the French Alternative Energies and Atomic Energy Commission (Commissariat à l’énergie atomique et aux énergies alternatives – CEA), the French national power utility (Électricité de France – EDF) and the Laue-Langevin Institute (ILL) to submit by 1 June 2011 at the latest, a memorandum describing the methodology they adopted in order to conduct the complementary safety assessment (évaluation complémentaire de la sûreté – ECS) for some of their installations with respect to the nuclear accident that occurred at the Fukushima-Daiichi Nuclear Power Plant (NPP) in Japan, on 11 March 2011.

Reactor No. 1 of the Fessenheim nuclear power plant : ASN's position
In its opinion No. 2011-AV-0120 of 4 July 2011, ASN considers that subject to the forthcoming conclusions of the complementary safety assessments initiated following the Fukushima accident and in view of the result of the third periodic safety review of reactor No. 1 of the Fessenheim nuclear power plant, that reactor is capable of being operated for a period of ten more years after the third review, provided that the requirements in ASN resolution No. 2011-DC-0231 dated 4 July 2011 are complied with, particularly the following two main requirements...

Increase of requirements on radiotherapy medical devices
Two serious incidents in 2006 and 2007 led the French authorities to implement a series of measures to strengthen the security of the practice of external radiotherapy.
In line with these measures, ASN and AFSSAPS have committed a specific reflection on the relationship between the radiation protection requirements of the Directive 97/43/Euratom and IAEA recommendations to the essential requirements of Directive 93/42/EEC applicable to devices including external radiotherapy linear accelerators of electrons.

Regulatory status of small amount of radioactive substances added to lamps
HERCA, the association of the Heads of European Radiological protection Competent Authorities, approves an interim Statement promoting a consistent European approach to the processes of national assessment and regulatory decisions on the use of lamps containing small amounts of radioactive substances. With this aim, the results of national assessments and regulatory decisions on this issue will be shared in Europe through HERCA. As consumer goods are introduced in open markets in Europe, HERCA recognises more generally the need for harmonization of the radiation safety regulation of goods containing small quantities of radioactive material.

Environmental radioactivity monitoring adopted in France
To estimate radioactivity levels across French territory following releases from the Fukushima Daiichi nuclear power plant, ASN asked operators to demonstrate particular vigilance regarding the results of measurements made and to step up monitoring. Additional analyses were requested by ASN on 22 March 2011 relative to monitoring the air, entailing measuring the radioactivity levels of aerosols and gaseous iodines.

ASN asks EDF to carry out a full analysis of sensitivity and uncertainties ...
Following its examination of the “Fuel Cycle” file, ASN has asked EDF, in a letter dated 9 May 2011, to produce a full analysis of sensitivity and uncertainties relating to nuclear fuel management within a year and to update this analysis every two years; ASN has also asked EDF to submit to it a new update of the “French Fuel Cycle” file in 2016. Further requests have also been made regarding technical aspects of management of and developments in new fuels, as well as storing spent fuel.

French audit and European stress tests at nuclear facilities
ASN believes that it is essential to learn from the recent accident in Japan, in the same way as after the Three Mile Island and Chernobyl accidents. The acquisition of in-depth feedback will involve a long process stretching over several years. Some lessons, however, can already be learned.

Health and safety inspection at EPR reactor
ASN oversees occupational health and safety inspection at French nuclear power plants . It provides coordinated oversight of the health, safety, working conditions and quality of employment of EDF employees, as well as those of EDF service providers and subcontractors, just as it does for nuclear safety at facilities. This activity covers the construction, operation and decommissioning of nuclear power plants .
