ASN Report 2018

T he Orléans division regulates nuclear safety, radiation protection and the transport of radioactive substances in the 6 départements of the Centre-Val de Loire region. Centre-Val de Loire region In 2018, ASN carried out 145 nuclear safety and radiation protection inspections: 101 inspections of the nuclear installations of the EDF sites of Belleville‑sur‑Loire, Chinon, Dampierre‑en‑Burly and Saint-Laurent-des-Eaux, and 44 inspections in small-scale nuclear activities in the Centre‑Val de Loire region. ASNcarried out 67 days of labour inspections in the nuclear power plants. In 2018, 11 significant events rated level 1 on the INES scale were reported by the licensees of the EDF nuclear installations in the Centre‑Val de Loire region, to which can be added 7 general events rated level 1 on the INES scale which concerned some of the region’s NPPs. In small-scale nuclear activities, one event rated level 1 on the INES scale was reported in 2018, while 3 events concerning radiotherapy patients were rated level 1 on the ASN-SFRO scale. ASN inspectors issued three violation reports in the exercise of their oversight duties Belleville-sur-Loire nuclear power plant The Belleville‑sur‑Loire NPP is situated in the north- east of the Cher département , on the left bank of the river Loire, at the crossroads of four départements (Cher, Nièvre, Yonne and Loiret) and two administrative regions (Bourgogne‑Franche‑Comté and Centre‑Val de Loire). The NPP comprises two reactors of 1,300 MWe, which were commissioned in 1987 and 1988 and constitute BNIs 127 and 128 respectively. ASN considers that the performance of the Belleville‑sur‑Loire NPP is on the whole in line with the general assessment of EDF in the areas of radiation protection and the environment. The performance with regard to safety remains below average, despite the notable improvements made in 2018 and which remain to be consolidated. In the area of safety, there are still numerous significant events resulting from a lack of rigour in operational control of the facility and ASN observes only slight progress in this respect, despite the alerts of the previous years. To give an example, EDF reported a significant event rated REGIONAL OVERVIEWOF NUCLEAR SAFETY AND RADIATION PROTECTION THE INSTALLATIONS AND ACTIVITIES TO REGULATE COMPRISE: ཛྷ ཛྷ BNIs: ݸݸ the Belleville-sur-Loire NPP (2 reactors of 1,300 MWe); ݸݸ the Dampierre-en-Burly NPP (4 reactors of 900 MWe); ݸݸ the Saint‑Laurent‑des‑Eaux site: the NPP in operation (2 reactors of 900 MWe), and the 2 French Gas-Cooled Reactors (GCR) undergoing decommissioning and the irradiated graphite sleeve storage silos; ݸݸ the Chinon site: the NPP in operation (4 reactors of 900 MWe), the 3 French GCRs undergoing decommissioning, the Irradiated Material Facility (AMI) and the Inter-Regional Fuel Warehouse (MIR); ཛྷ ཛྷ small-scale nuclear activities in the medical sector: ݸݸ 8 external-beam radiotherapy departments; ݸݸ 3 brachytherapy departments; ݸݸ 10 nuclear medicine departments; ݸݸ 35 centres performing fluoroscopy-guided interventional procedures; ݸݸ 38 computed tomography scanners; ݸݸ some 2,700 medical and dental radiology devices; ཛྷ ཛྷ small-scale nuclear activities in the veterinary, industrial and research sectors: ݸݸ 10 industrial radiography companies; ݸݸ about 330 industrial, veterinary and research radiography devices; ཛྷ ཛྷ activities linked to the transport of radioactive substances. see p. 200 see p. 230 see p. 256 ASN report on the state of nuclear safety and radiation protection in France in 2018  41
