The inspections of ITER Organisation –the nuclear licensee of the facility– conducted by ASN on the Cadarache site and in South Korea on the manufacturing site of some of the sectors of the vacuum chamber, conclude that the safety requirements are taken into account in a generally satisfactory manner by the entire chain of outside contractors, as from the facility design stage. ɀɀƺɀɀȅƺȇɎ Ȓǔ Ɏǝƺ !0 !ƏƳƏȸƏƬǝƺ ƬƺȇɎȸƺ ASN considers that the level of nuclear safety of Ɏǝƺ !0 !ƏƳƏȸƏƬǝƺ ƬƺȇɎȸƺ ǣȇ א ׎׏ ژח ǣɀ Ȓȇ Ɏǝƺ ɯǝȒǼƺ satisfactory. It does nevertheless note persistent disparities between the facilities of the centre. ASN considers that the BNIs are operated satisfactorily on the whole, especially the control of the condition of the equipment, compliance with the operating baseline requirements and, more generally, the radiation protection measures taken by the senior management of the centre. Improvements are however expected in waste management and the control of fire risks. Nuclear safety management is on the whole satisfactory, but, as in 2018, ASN considers that the sharing of experience feedback and good practices between facilities must be improved, as must the management of deviations. Moreover, despite a noted improvement in 2019, the licensee’s monitoring of outside contractors and subcontractors shows contrasts; the activities carried out under contracts concerning the centre must be monitored with the same rigour as those carried out under contracts concerning the BNIs. ASN considers that the organisation in place for the periodic safety reviews of the facilities in on the whole satisfactory. The extent to which the results of studies are taken on board or the human resources allocated to performing them seem ȇƺɮƺȸɎǝƺǼƺɀɀ ɎȒ ɮƏȸɵ ǔȸȒȅ Ȓȇƺ zX ژ ɎȒ ƏȇȒɎǝƺȸِ ³z ɯǣǼǼ ƫƺ ƏɎɎƺȇɎǣɮƺ ɎȒ Ɏǝƺ ƏȵȵǼǣƬƏɎǣȒȇ Ȓǔ Ɏǝƺ zX ژ ȵƺȸǣȒƳǣƬ safety review action plans, particularly with regard to carrying out the work identified in the reviews. ASN considers that the CEA ensures the on-site transport of radioactive substances at the Cadarache centre in a satisfactory manner. Improvements have been made in the centre’s baseline requirements with regard to organization and support to the BNIs, particularly as concerns the maintenance of packages and vehicles. With regard to emergency situation management, the CEA has initiated a plan of action to meet the ȸƺȷɖǣȸƺȅƺȇɎɀ Ȓǔ ³z ȸƺɀȒǼɖɎǣȒȇ א ׎׏ ٮ!(ٮו ׎ ژאחד Ȓǔ ׏ ژב hɖȇƺ א ׎׏ ו ِ Áǝƺ ȅƏǣȇ ǣȅȵȸȒɮƺȅƺȇɎɀ ƏƬǝǣƺɮƺƳ Ȓȸ ژ ɖȇƳƺȸ ɯƏɵ ƬȒȇƬƺȸȇ Ɏǝƺ ƺȅƺȸǕƺȇƬɵ ȅƏȇƏǕƺȅƺȇɎ agreements signed with the outside organisations, the emergency exercises, the instruction and training of the personnel involved in emergency management and learning lessons from experience feedback.

ASN and ASND have made a position statement on the CEA’s decommissioning and waste management strategy. This strategy leads to changes in the projects for facility renovation and the construction of new facilities for the CEA Cadarache centre, in favour of certain priority decommissioning work projects. ASN will nevertheless make sure that the CEA keeps the in-service facilities at the right operating level, while at the same time ensuring the progress of the priority decommissioning and legacy waste retrieval and packaging projects. ASN considers that the radiation protection situation of the CEA centre is satisfactory. Lastly, ASN observes that the level of environmental protection is relatively satisfactory. With regard to discharge management, the licensee has proposed an action plan to improve the management of stormwater ǣȇ ƬƺȸɎƏǣȇ ȒǼƳ zXɀ ٢ zX ٮובژ ƏȇƳ zX ژהדژ ǣȇ ȵƏȸɎǣƬɖǼƏȸ٣ ɎȒ ƬȒȅȵǼɵ ɯǣɎǝ Ɏǝƺ ȸƺȷɖǣȸƺȅƺȇɎɀ Ȓǔ Ɏǝƺ…ȸƳƺȸ Ȓǔ ژו IƺƫȸɖƏȸɵ א ׎׏ א ƏȇƳ ³z ȸƺɀȒǼɖɎǣȒȇ א ׎׏ ٮ!(ٮב ׎ הב ׎ ژ Ȓǔ ׏ ژה hɖǼɵ א ׎׏ ב ِ ASN has asked that the plan be supplemented.
