ASN Report 2017

212 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 Bourgogne-Franche-Comté The Dijon division regulates nuclear safety, radiation protection and the transport of radioactive substances in the 8 départements of the Bourgogne-Franche-Comté region. I n 2017, ASN conducted 71 inspections in the Bourgogne- Franche-Comté region, comprising 28 inspections in the medical sector, 30 inspections in the industrial research and veterinary sectors, 3 inspections concerning radon exposure, 3 oversight inspections of the activity of approved organisations and laboratories and 7 inspections on the transport of radioactive substances. Among the significant events notified and analysed to draw lessons, 4 events concerning radiotherapy patients were rated level 1 on the ASN-SFRO scale. The manufacturing plants of Areva NP situated in the Bourgogne-Franche-Comté region were also the subject of particular scrutiny by ASN in 2016 and 2017 following the discovery of irregularities in components manufactured by Creusot Forge. The steps taken by ASN in this respect are described in chapter 12. The installations and activities to regulate comprise: ཛྷ ཛྷ small-scale nuclear activities in the medical sector: -- 8 external-beam radiotherapy departments (21 accelerators, 2 contact therapy devices); -- 4 brachytherapy departments; -- 14 nuclear medicine departments, 3 of which practice internal vectorised radiotherapy; -- 37 centres performing fluoroscopy- guided interventional procedures; -- 51 computed tomography scanners; -- about 800 medical radiology devices; -- about 2,000 dental radiology devices; ཛྷ ཛྷ small-scale nuclear activities in the veterinary, industrial and research sectors: -- 208 veterinary practices; -- 390 industrial and research establishments, including 28 companies exercising an industrial radiography activity, 166 users of devices for detecting lead in paint, 1 cyclotron accelerator for research and the production of medical imaging drugs and 2 industrial accelerators for radiography and polymer cross-linking; ཛྷ ཛྷ approved laboratories and organisations: -- 3 organisations approved for radiation protection controls, with 6 agencies; -- 5 organisations approved for radon monitoring and 1 laboratory approved for measuring radioactivity in the environment. 1. Assessment by domain 1.1 Radiation protection in the medical field Radiotherapy and brachytherapy ASN performed 5 inspections of radiotherapy and brachytherapy activities in 2017. Three commissioning inspections of new items of equipment were also carried out. On the whole, the inspected departments have complied with ASN resolution 2009-DC-0150 requiring the setting up of a specific organisation to ensure treatment safety and quality. Two of the inspected departments must however make improvements, particularly in the studies of the risks for patients. The inspections revealed a continued dynamic approach to adverse event analysis and significant event notification. In 2017, 4 significant events concerning the radiation protection of radiotherapy patients were rated level 1 on the ASN-SFRO scale. Three of these events concerned errors in the medical procedure while the fourth was due to equipment failure. ASN had placed the University Hospital of Besançon (CHRUB) under tightened monitoring since the second quarter of 2015 on account of substantial changes in its organisation and being significantly behind schedule in radiation protection in the areas of radiotherapy and interventional practices.
