ASN Report 2017

235 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 Ile-de-France The Orléans and Paris divisions jointly regulate nuclear safety, radiation protection and the transport of radioactive substances in the 8 départements of the Ile-de-France region. A SN carried out 205 inspections in the Ile-de-France region in 2017, of which 39 were in the field of nuclear safety, 146 in small-scale nuclear activities and 20 in the transport of radioactive substances. Five Safety-related Significant Events (ESS) in BNIs in Ile-de- France were rated level 1 on the INES scale. In small-scale nuclear activities, 10 Significant Radiation Protection Events (ESR) were rated level 1 and 3 events were rated level 2 on the INES scale. In addition to these, 14 events involving radiotherapy patients were rated level 1 and one event rated level 2 on the ASN-SFRO scale. The installations and activities to regulate comprise: ཛྷ ཛྷ BNIs regulated by the Orléans division -- the 8 BNIs in the CEA Saclay centre, including the Osiris and Orphée experimental reactors; -- the UPRA (Artificial Radionuclide Production Plant) operated by CIS bio international in Saclay; -- the 2 BNIs undergoing decommissioning in CEA’s Fontenay-aux- Roses centre. ཛྷ ཛྷ small-scale nuclear activities in the medical sector regulated by the Paris division: -- 26 external-beam radiotherapy departments; -- 13 brachytherapy departments; -- 59 nuclear medicine departments; -- about 170 centres performing fluoroscopy-guided interventional procedures; -- more than 200 centres in possession of at least one Computed Tomography (CT) scanner ; -- about 850 medical radiology centres; -- about 8,000 dental radiology devices; ཛྷ ཛྷ small-scale nuclear activities in the industrial and research sectors under the oversight of the Paris division: -- about 650 users of veterinary radiology devices; -- 9 industrial radiography companies using gamma radiography devices; -- more than 200 licenses concerning research activities involving unsealed radioactive sources; ཛྷ ཛྷ organisations approved by ASN: -- 11 organisations approved for radiation protection controls. 1. Assessment by domain 1.1 The nuclear installations CEA’s Saclay Centre ASN considers that the safety of operation of the CEA Saclay Centre BNIs is satisfactory. In 2017, the Saclay and Fontenay-aux-Roses centres were brought together within a single centre (CEA Paris-Saclay). ASN points out that particular attention must be paid to the control of safety and radiation protection in the Saclay BNIs during the consolidation of this new organisation. As no decommissioning authorisation application file had been submitted for the Osiris reactor, ASN issued resolution 2017-DC-0599 of 1st August 2017 requiring submission of this file before 29th June 2018. Pending its decommissioning authorisation, operations to remove radioactive and hazardous substances and to prepare for decommissioning are in progress with an organisation adapted to the new status of the reactor. The schedule for these operations was detailed at the end of 2016 and is giving rise to technical examinations by ASN. The CEA moreover stated on 7th October 2017 that it wished to push back the shutdown of BNI 72, inwhich the solidwaste from the Saclay centre facilities is treated, from 31st December 2017
