ASN Report 2017

203 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 The Lyon division regulates nuclear safety, radiation protection and the transport of radioactive substances in the 12 départements of the Auvergne-Rhône-Alpes region. I n 2017, the Lyon division carried out 334 inspections in the Auvergne-Rhône-Alpes region, of which 111 were in the nuclear power plants of Bugey, Saint-Alban/ Saint-Maurice, Cruas-Meysse and Tricastin, 95 in other nuclear plants and facilities undergoing decommissioning, 118 in small-scale nuclear activities and 10 in the transport of radioactive substances. ASN also carried out 42 days of labour inspections in the four nuclear power plants and on the Creys-Malville site. ASN was notified of 22 significant events rated level 1 on the INES scale, of which 21 occurred in BNIs and 1 in small-scale nuclear activities. One event was rated level 2 on the INES scale; this is due to the fact that the embankment protecting the Tricastin facilities against flooding would not withstand the Safe Shutdown Earthquake (SSE). In the small-scale nuclear activities, 13 events concerning radiotherapy patients were rated level 1 on the ASN-SFRO scale and one was provisionally rated level 2. The installations and activities to regulate comprise: ཛྷ ཛྷ 4 NPPs operated by EDF: -- Bugey (4 reactors of 900 MWe); -- Saint-Alban/Saint-Maurice (2 reactors of 1,300 MWe); -- Cruas-Meysse (4 reactors of 900 MWe); -- Tricastin (4 reactors of 900 MWe); ཛྷ ཛྷ the nuclear fuel fabrication plants of Areva NP (now called Framatome) in Romans-sur-Isère; ཛྷ ཛྷ the nuclear fuel cycle plants operated by Areva NC (now called Orano) and its subsidiaries on the Tricastin industrial platform; ཛྷ ཛྷ the Operational Hot Unit at Tricastin (BCOT) operated by EDF; ཛྷ ཛྷ the High Flux Reactor operated by the Laue-Langevin Institute in Grenoble; ཛྷ ཛྷ the Activated waste packaging and storage facility (Iceda) under construction on the Bugey nuclear site and the Bugey Inter-Regional Warehouse (MIR) operated by EDF; ཛྷ ཛྷ the Superphénix reactor undergoing decommissioning at Creys-Malville, and its auxiliary installations; ཛྷ ཛྷ reactor 1 undergoing decommissioning at the Bugey NPP operated by EDF; ཛྷ ཛྷ the Ionisos irradiation facility in Dagneux; ཛྷ ཛྷ the nuclear fuel fabrication plant and pelletising unit of SICN in Veurey- Voroize, waiting to be delicensed; ཛྷ ཛྷ the CEA (French Alternative Energies and Atomic Energy Commission) reactors and plants in Grenoble, decommissioned and waiting to be delicensed; ཛྷ ཛྷ the CERN international research centre located on the Swiss-French border; ཛྷ ཛྷ small-scale nuclear activities in the medical sector: -- 22 external-beam radiotherapy departments; -- 6 brachytherapy departments; -- 23 nuclear medicine departments; -- about 200 centres performing fluoroscopy-guided interventional procedures; -- 120 computed tomography scanners; -- some 10,000 medical and dental radiology devices; ཛྷ ཛྷ small-scale nuclear activities in the industrial and research sectors: -- one synchrotron ; -- 700 veterinary structures (practices or clinics); -- about 30 industrial radiology agencies; -- about 600 users of ionising radiation in the industrial sector; -- about 100 research units; -- 3 head offices and 8 agencies of approved bodies. 1. Assessment by domain 1.1 The nuclear installations Nuclear power plants Bugey nuclear power plant ASN considers that the nuclear safety, radiation protection and environmental protection performance of the Bugey NPP is in line with its general assessment of EDF’s performance. Although progress was observed in 2017, the control of certain particular operating conditions must be improved. Shortcomings in the fire prevention culture led to one of the two activations of the on-site emergency plan in June 2017. With regard to nuclear safety, the Bugey NPP made progress in 2017 in the areas of reactor control, serenity in the control room and compliance with procedures. The site must nevertheless remain vigilant in the configuring of systems, an area in which EDF encountered difficulties in 2017, and in the management of the baseline requirements applicable
