Abstracts ASN Report 2019

ASN tested the ILL’s emergency organisation and resources during an inspection with an unannounced exercise outside working hours. ASN noted appropriate responsiveness, good knowledge of the facility and of the actions to take in an accident situation, and fluidity in the actions of the response teams. The periodic safety review concluding report is currently being examined. The licensee’s responsiveness and the quality of the information provided for the purpose of the examination are considered satisfactory. ASN carried out a tightened inspection focusing on the hypotheses and the conclusions of the ILL periodic safety review and the defining and implementation of its plan of action. ASN will continue its examination of the safety review report ǣȇ א ׎ א ׎ ژ ƏȇƳ ɯǣǼǼ ƫƺ ƏɎɎƺȇɎǣɮƺ ɎȒ Ɏǝƺ ɮƏȸǣȒɖɀ ƏƬɎǣȒȇ ȵǼƏȇɀ implemented by the ILL as a follow-up to the inspections of א ׎׏ ژח ƏȇƳ ǼǣǔɎǣȇǕ Ȓǔ Ɏǝƺ ƬȒȅȵǼǣƏȇƬƺ ȇȒɎǣƬƺِ XȒȇǣɀȒɀ ǣȸȸƏƳǣƏɎȒȸ The company Ionisos operates an industrial irradiator in Dagneux, situated in the Ain département .

The level of safety of the facility was found to be satisfactory in 2019. The ASN inspection focused specifically on the sealed source requalification operations carried out within the facility; these operations were conducted properly. An inspection targeting the periodic safety review was also carried out in 2019, and highlighted points requiring particular attention in the assimilation of the studies and conclusions of the safety review and the experience feedback analysis. !0«z ƏƬƬƺǼƺȸƏɎȒȸɀ ƏȇƳ ȸƺɀƺƏȸƬǝ ƬƺȇɎȸƺ Following the signing of an international agreement between IȸƏȇƬƺً ³ɯǣɎɿƺȸǼƏȇƳ ƏȇƳ !0«z Ȓȇ ׏ ژד zȒɮƺȅƫƺȸ א ׎׏׎ً ³z ƏȇƳ the OFSP (Swiss Federal Office of Public Health) –the Swiss radiation protection oversight body– are contributing to the verification of the safety and radiation protection requirements applied by CERN.

ASN considers that the safety of Superphénix decommissioning operations and of APEC operation is on the whole satisfactory. ASN has authorised commencement of the second Superphénix decommissioning phase, which consists in opening the reactor pressure vessel to dismantle its internal components, in dedicated facilities constructed in the reactor building, by direct or remote manipulation. The safety and radiation protection measures implemented by EDF for these operations are on the whole satisfactory.

More generally, ASN notes that EDF was good about meeting its various commitments in 2019, but will remain attentive to the way defence in depth is taken into account and to the implementation of the plan addressing equipment obsolescence.
