ASN notes that the storage yard facilities are well kept. The licensee must nevertheless still deal with several damaged legacy packages. Following its inspections in 2019, ASN asked the licensee to review the retention structure inspection practices, to improve the monitoring of the anomalies observed during the patrol inspections and to ascertain that all nuclear materials are correctly labelled in accordance with the regulations. ASN is expecting the licensee to make progress with regard to the emergency management building and the equipment it contains. The facility baseline requirements must effectively be upgraded to guarantee operation of the emergency centre and mobile equipment. ¨ ژדב ǔƏƬǣǼǣɎɵ Following on from the delicensing process of the Pierrelatte ( zX ژ ƫɵ (ƺƬǣɀǣȒȇ Ȓǔ Ɏǝƺ ¨ȸǣȅƺ xǣȇǣɀɎƺȸً zX ژ ׏ ٹژחו ¨ ٺדב ǝƏɀ ƫƺƺȇ created.

The start-up of the last bench, which will finalise the complete commissioning of the facility, was planned for 2019. However, substantial difficulties were encountered with the sealing of the bench. These difficulties led Orano Cycle to carry out sealing reinforcement operations under conditions that ASN, after inspection, considered inappropriate. More generally, ASN considers that the licensee must continue its efforts to increase its operational rigour in this facility. The licensee must also improve its oversight of the teardown of worksites entrusted to outside contractors. In 2020, ASN will be extremely vigilant regarding the recon- ditioning of the third UF 6 ژ ƏȇƏǼɵɀǣɀ ƏȇƳ ɀƏȅȵǼǣȇǕ ƫƺȇƬǝ ƫƺǔȒȸƺ any active tests are performed.

Activity transfer and tooling disassembly continued in 2019. ASN considers that the level of safety of the BCOT is on the whole satisfactory. In 2019, ASN verified the modifications the BCOT made to its facility for cutting up the used RCC guide tubes of the pressurised water reactors operated by EDF. In 2020, ASN will be attentive to the resumption of these operations and the last equipment removal operations.
