Abstracts ASN Report 2019

With regard to maintenance, ASN considers that the situation is generally satisfactory, in a context of intense activity linked to the ten-yearly outage of reactor 1. ASN notes the progress in monitoring work operations, but the monitoring is still not sufficiently relevant and appropriate for the facility modification activities. The licensee must also ensure rigorous traceability in the processing of anomalies observed on the equipment. With regard to radiation protection, ASN considers that the licensee has managed to continue correcting the malfunctions in worker protection measures observed in the previous years.

ASN notes a positive trend in environmental protection, but considers that the licensee must remain vigilant regarding the on-site management of effluents and the containment of liquid substances. Lastly, the oversight ensured through the labour inspections revealed no major nonconformities: ASN focused particular attention on the conformity of the fuel handling machine during the ten-yearly outage of reactor 1, further to the corrections made by the licensee. ɖƫƺ ɯƏɀɎƺ ƳǣɀȵȒɀƏǼ ǔƏƬǣǼǣɎɵ ɖɎǝȒȸǣɀƺƳ ƫɵ Ə (ƺƬȸƺƺ Ȓǔ ژג ³ƺȵɎƺȅƫƺȸ ׏ ژחזח ƏȇƳ ƬȒȅ ٮ missioned in January 1992, the Aube repository (CSA) took over from the Manche repository which ceased its activities in July 1994, while benefiting from the experience gained with the latter.

ASN considers that the CSA is operated under satisfactory conditions with regard to safety, radiation protection and environmental protect. In 2019, with the authorisation of ASN, the CSA commissioned the package inspection facility which gives it more effective means of checking the quality of the received packages. The CSA has moreover started the construction of new waste disposal structures. The technical analysis of the CSA’s periodic safety review report, intended in particular to assess the safety of the facility according to the planned development of its activities over the next ten years, continued in 2019. ASN shall give its opinion on the conditions of operation of the CSA in 2020.
