ASN considers that the level of nuclear safety and radiation protection of Chicade is on the whole satisfactory. With regard to environmental protection, the CEA has undertaken to review the impact study of its facility to take into account the gaseous discharges of tritiumwhich were not provided for in its baseline requirements, and to submit a request to modify the facility creation decree once the ongoing examination of the facility’s periodic safety review file is completed. !ƺƳȸƏ ɀɎȒȸƏǕƺ ǔƏƬǣǼǣɎɵ – CEA Centre ³ǣȇƬƺ א ׎׎ ה ً Ɏǝƺ !ƺƳȸƏ ǔƏƬǣǼǣɎɵ ٢ zX ژ ׏ גה ٣ ȵȸȒƬƺɀɀƺɀ intermediate-level long-lived waste (ILW-LL) pending the creation of appropriate disposal routes. The CEA forecasts that this facility will be filled to capacity by 2027. The studies concerning a project to double the storage capacity should start in 2020. The CEA sent ASN the periodic safety review report for the facility in November 2017, and ASN is currently examining it. The licensee has been asked for additional information concerning the conformity check of the facility’s baseline requirements and the external hazards.

ASN considers that the level of nuclear safety and radiation protection of the facility is relatively satisfactory. The CEAmust nevertheless improve operating rigour, in particular regarding compliance with radiation protection requirements and the formal tracking of modifications. In view of the personnel changes, particular attention must be given to maintaining skills. 0ǔˢɖƺȇɎ ƏƳɮƏȇƬƺƳ ȅƏȇƏǕƺȅƺȇɎ ƏȇƳ ȵȸȒƬƺɀɀǣȇǕ ǔƏƬǣǼǣɎɵ ٢ ǕƏɎƺ٣ – CEA Centre Áǝƺ ǕƏɎƺ ǔƏƬǣǼǣɎɵ ٢ zX ژ ׏ ו ׏٣ً ƬȒȅȅǣɀɀǣȒȇƺƳ ǣȇ א ׎׏ ژג ɎȒ ȸƺȵǼƏƬƺ zX ٮובژ ɯǝǣƬǝ ǣɀ ȇȒɯ ɀǝɖɎ ƳȒɯȇً ɖɀƺɀ Əȇ ƺɮƏȵȒȸƏɎǣȒȇ process to concentrate radioactive liquid effluents containing mainly beta- and gamma-emitting radionuclides.

In addition, the three primary/secondary heat exchangers were introduced into the dedicated bunker of the reactor building in the second half of 2019. The lining of the pools and channels of the nuclear auxiliaries building is currently being installed. The off-site manufacture of large equipment items, which includes the reflector, is still in progress. ASN considers that the nuclear safety requirements are taken properly into account in the construction of the facility and that the CEA’s management of the construction worksite is satisfactory. Deviations are managed with rigour and efficiency. Delays in construction and a third-party review of its project led the CEA to make a request to push back the commissioning ƳƺƏƳǼǣȇƺ ƫɵ ژח ɵƺƏȸɀ ɯǣɎǝ ȸƺɀȵƺƬɎ ɎȒ Ɏǝƺ ǣȇǣɎǣƏǼ ƳƺƏƳǼǣȇƺ Ȓǔ October 2019, a request which was authorised by a Decree Ȓǔ ׏׎ …ژ ƬɎȒƫƺȸ א ׎׏ ژח ƏǔɎƺȸ ȸƺƬƺǣɮǣȇǕ Ə ǔƏɮȒɖȸƏƫǼƺ ȒȵǣȇǣȒȇ ǔȸȒȅ ASN, which considered in particular that the elements essential for the protection of people and the environment were not modified and that the CEA was implementing a procedure guaranteeing proper conservation of the equipment already installed or waiting to be installed on site.
