ASN Report 2018

ÎLE-DE-FRANCE REGIONAL OVERVIEWOF NUCLEAR SAFETY AND RADIATION PROTECTION the management of inspections and periodic tests, the handling of deviations and the tracking of maintenance operations. To give an example, CIS bio international reported a significant event rated level 1 on the INES scale for deficiencies in the management and traceability of inspections and periodic tests. ASN also observed that, in view of the delays that have built up in recent years and despite the efforts made since the end of 2016, the licensee had difficulty in complying with the requirements resulting from the previous periodic safety review. By ASN resolution 2018-DC-0628 of 15 March 2018, ASN gave CIS bio international formal notice to comply with the unfulfilled requirements, setting deadlines of mid-2018 and end of 2018. ASN checked compliance with these new deadlines in inspections. Alongside this, the application of new regulatory requirements is not adequately anticipated. This has more specifically led ASN to give CIS bio international, through resolution2018-DC-0629 of 15 March 2018, formal notice to draw up a waste management study and establish corresponding general operating rules that are in conformity with resolution 2015-DC-0508. Lastly, complementary studies concerning the consequences of accident situations are currently being examined. The risks created by the installation shall be significantly reduced in the medium term. This reduction will be due to the stopping of the activity associated with disused high- level sealed sources and the production of iodine-131-based radiopharmaceuticals. These changes in operation, for which the deadline is the end of 2019, will be examined during the examination of the periodic safety review report submitted in the 2nd half of 2018. More broadly speaking, ASN expects a lasting turnaround of CIS bio international. Operating rigour, the safety culture, the oversight of operations, the cross-functionality of the organisation, and compliance with the baseline requirements of the facility and ASN resolutions must all be improved. CEA’s Fontenay‑aux‑Roses centre Created in 1946 as the CEA’s first research centre, the Fontenay‑aux‑Roses site is continuing its transition from nuclear activities towards research activities in living sciences. The Fontenay-aux-Roses centre comprises two BNIs, namely Procédé (BNI 165) and Support (BNI 166). BNI 165 accommodated the research and development activities on nuclear fuel reprocessing, transuranium elements, radioactive waste and the examination of irradiated fuels. These activities were stopped in the 1980s-1990s. BNI 166 is a facility for the characterisation, treatment, reconditioning and storage of legacy radioactive waste and waste from the decommissioning of BNI 165. More generally, the CEA’s decommissioning and waste management strategy is subject to examination by ASN (see chapter 13). Procédé and Support installations – CEA Centre The decommissioning of these two installations which constitute BNI 165 and 166 respectively, was authorised by two Decrees of 30 June 2006. The initially planned duration for the decommissioning operations was about ten years. The CEA informed ASN that, due to strong presumptions of radioactive contamination beneath one of the buildings, to unforeseen difficulties and to a change in the overall decommissioning strategy of the CEA’s civil centres, the decommissioning operations would extend beyond 2030, and in June 2015 it filed an application to change the prescribed decommissioning time frames. ASN deemed that the first versions of these files were not admissible. In accordance with its commitments of 2017, in the 1st quarter of 2018 the CEA sent the new version of the files aiming to extend the decommissioning authorisation for the nuclear installations of the Fontenay‑aux‑Roses centre. 2018 witnessed slippages in the performance of the studies, in project scheduling and in the decommissioning operations schedule. Thus, the complements to the on-site emergency plan expected in 2017 were not submitted to ASN until the end of 2018 and will be examined in 2019. Assessment of the CEA Fontenay‑aux‑Roses centre ASN observes that the CEA once again has numerous difficulties in meeting the deadlines of projects that are fundamental for safety. ASN expects an improvement in the quality of the studies submitted by the CEA, which must be self-sufficient and include more detailed analyses. Control of the fire risk remains a major issue. ASN registered improvements in 2018; the CEA provided elements demonstrating control of the fire risk at the end of the year. Alongside this, equipment qualification compliance and discharge monitoring are satisfactory, but meeting commitments and control of containment must still be improved. Likewise, there is room for improvement in the detection of deviations and the monitoring of service providers. ASN never-theless notes the responsiveness of the personnel and good organisation of the various themes inspected, especially waste management.
