Abstracts ASN Report 2019

At the design and construction stage, ASN –aided by its technical support organisation– assesses the safety analysis reports describing and justifying the design principles, equipment and system design calculations, utilisation rules and test procedures, and quality organisation provisions implemented by the prime contractor and its suppliers. It also analyses the facility’s environmental impact assessment. ASN regulates and oversees the construction and manufacture of structures and equipment, in particular that of the main primary system and the main secondary systems of Pressurised Water Reactors (PWR). In accordance with the same principles, it checks the packages intended for the transport of radioactive substances. Once the nuclear facility has been commissioned, following ASN authorisation, all changes to the facility or its operation made by the licensee that could affect security, public health and safety, or the protection of the environment, are notified to ASN or submitted to it for authorisation. Moreover, the licensee must perform periodic safety reviews to update the assessment of the facility, taking into account any changes in techniques and regulations, and experience feedback. The conclusions of these reviews are submitted by the licensee to ASN, which can issue new binding requirements for continued operation. • Áǝƺ ȒɎǝƺȸ ǔǣǼƺɀ ɀɖƫȅǣɎɎƺƳ ƫɵ zX ǼǣƬƺȇɀƺƺɀ A large number of dossiers concern specific topics such as fire protection, fuel management in PWRs, relations with the outside contractors, etc. The licensee therefore periodically provides activity reports as well as summaries of water intake, liquid and gaseous discharges and waste produced. 629 Personnel and organisation 651 Nuclear safety 174 General inspection and others 128 Radiation protection 252 0ǔˢɖƺȇɎً ɯƏɀɎƺ and environmental monitoring 264 Pressure equipment TOTAL 2,283 60 Emergency management 125 Prevention of risks ǣȇƬǼɖƳǣȇǕ ˡȸƺ GRAPH 1 Breakdown of inspection days in the BNIs by topic in 2019 (*) 433 Fluoroscopy-guided interventional practices 224 External radiotherapy 61 Computed tomography 6 Other medical activities TOTAL 949 169 Nuclear medicine 56 Brachytherapy 45 % 3 % 28 % 33 % 35 % % = percentage of the pool inspected GRAPH 3 Breakdown of inspection days in the medical field by nature of activity in 2019 (*) * Inspection day figures rounded off. 25 Industry 16 On-site transport operations (BNI Order) 2 Rail, air and maritime transport 18 Packaging (package design; manufacture or maintenance of packaging) 2 Fabrication TOTAL 141 33 BNI consignments 45 Medical GRAPH 2 Breakdown of inspection days in the transport of radioactive substances by topic in 2019 (*) 103 Distribution 102 X-ray and accelerators 197 Gamma radiogaphy 25 Gamma densitometry TOTAL 692 43 Veterinary surgeons 156 Other activities 66 Other NPX activities GRAPH 4 Breakdown of inspection days in small-scale nuclear industrial and veterinary activities by nature of activity in 2019 (*) ASN Report on the state of nuclear safety and radiation protection in France in 2019 147 03 ׎ ٲ ב REGULATION OF NUCLEAR ACTIVITIES AND EXPOSURE TO IONISING RADIATION
