ASN Report 2017

211 ASN report on the state of nuclear safety and radiation protection in France in 2017 Chapter 08  - Regional overview of nuclear safety and radiation protection AUVERGNE-RHÔNE-ALPES Romans-sur-Isère and Tricastin organised public information meetings on nuclear activities and on their work. The Lyon division and the CLIs of the Auvergne-Rhône-Alpes region participated in the meeting of the Rhône Valley CLIs held on 18th and 19th May in Marseille. This event brought together about ten CLIs and the stakeholders (local authorities, departmental and regional councils, ASN, IRSN, licensees, etc.). Three themes (relations between the public, the licensee and ASN; the performance of independent analyses and expert assessments; waste management) were adopted with a view to sharing experience, and should lead to the creation in 2018 of a national working group on the management of very low level radioactive waste. 2.2 International action The Lyon division continued its bilateral exchanges with the NRA (Japan’s Nuclear Regulation Authority) on inspection practices and the actions deployed further to the Fukushima Daiichi accident. A delegation of NRA inspectors was received in Lyon on this account. The exchanges focused on the organisational changes made at the NRA to reform oversight of the nuclear installations, and the conditions of putting the Japanese reactors back into service. The NRA inspectors visited the Bugey, Saint-Alban/Saint-Maurice and Areva NP Romans sites and took part in discussions with the licensees. A visit to the Bugey site was organised. The Lyon division also received a delegation of inspectors from the Norwegian nuclear regulation Authority, which took part in a joint waste management inspection at the ILL in Grenoble in July 2017. The two Authorities discussed inspection practices on the sidelines of this inspection. Lyon division inspectors visited a nuclear fuel manufacturing facility in Russia in order to compare the safety standards of that facility with those of the Areva NP plant in Romans-sur-Isère. One inspector also participated in a working group with the U.S. Nuclear Regulatory Commission (NRC), on decommissioning practices, the objectives of post-operational clean-out, and the management of nuclear waste in the United States. A visit was organised to the decommissioning worksite of the Zion NPP (Illinois), whose installations are very similar to those of the French pressurised water reactors. The Lyon division also continued its cross-inspection practices with the Swiss nuclear safety and radiation protection Authorities. Inspectors from the Swiss safety Authority (ENSI) took part in inspections on the Tricastin and Cruas-Meysse sites in April 2017. Inspectors from the Lyon division took part in an inspection at the Swiss Leibstat NPP and the Paul Scherrer Research Institute in September 2017. The Lyon division also continued its joint oversight actions with the Swiss Federal Office of Public Health, which is responsible for radiation protection oversight, and monitoring CERN in particular. Broadly speaking, these exchanges have permitted the sharing of good practices in the oversight of nuclear activities and radiation protection and in methods of decommissioning. 2.3 The other notable events ASN deployed its emergency organisation for 2 notable events that occurred on the Bugey NPP, namely a fire in the roof of a nuclear building and the failure of a reactor control component, neither of which had any consequences on the installation or the environment. These two situations demonstrated ASN’s ability to deploy its organisation to support the public authorities. In contrast, the national emergency exercise, planned to take place on the Saint-Alban/Saint-Maurice NPP on 28th and 29th November 2017, was partially cancelled due to the intrusion of an association on the Cruas-Meysse site. Only the post-accident management phase could be played out, on the second day.
