Abstracts ASN Report 2019

In 2019, ASN examined the requests to push back the deadlines for recovery of the legacy fission products solutions stored ǣȇ Ɏǝƺ ³¨I ژא ɖȇǣɎً Ɏǝƺ ɯƏɀɎƺ ǔȸȒȅ ɀǣǼȒ ׏ ב ׎ً ǔȸȒȅ ɀǣǼȒ R…ƏȇƳ from the SOC pools.

In view of the difficulties with the waste retrieval and conditioning projects, ASN has started an exploratory approach for monitoring the progress of the legacy waste retrieval and decommissioning projects on the La Hague site, which included a licensee self-assessment and an in-depth inspection at the end of 2019. ASN observes that the licensee has defined a satisfactory project management methodology, but progress is required in the actual management of these projects in order to meet the time lines. ɀɀƺɀɀȅƺȇɎ Ȓǔ Ɏǝƺ nƏ RƏǕɖƺ ɀǣɎƺ ASN considers that the performance of the Orano Cycle nƏ RƏǕɖƺ ɀǣɎƺ ǣȇ א ׎׏ ژח ǣɀ ɀƏɎǣɀǔƏƬɎȒȸɵ ǣȇ Ɏǝƺ ƏȸƺƏɀ Ȓǔ ȇɖƬǼƺƏȸ safety, radiation protection and environmental protection. With regard to nuclear safety, ASN notes an improvement ٫ɎȒ ƫƺ ƬȒȇɀȒǼǣƳƏɎƺƳ٫ ǣȇ Ɏǝƺ ȅƏȇƏǕƺȅƺȇɎ Ȓǔ Ɏǝƺ ȵƺȸǣȒƳǣƬ checks and tests resulting from the integration of the lessons learned from the significant events reported in the last few years. ASN has nevertheless observed several cases where the time intervals between checks have been exceeded because organisational deficiencies have affected their integration in the tracking tool. The licensee must also significantly improve its organisation for managing risks involving hazardous substances. During several inspections, ASN has observed shortcomings in the prevention of major accidents involving hazardous substances and a lack of means to control the conformity of the site’s Installations Classified for Protection of the Environment (ICPEs). ASN considers that the licensee must continue the efforts made in the monitoring of outside contractors, notably ƫɵ ژ ǣȅȵȸȒɮǣȇǕ Ɏǝƺ ȅȒȇǣɎȒȸǣȇǕ ȵǼƏȇ ȵȸƺȵƏȸƏɎǣȒȇ methodology and the formalising of the monitoring ƳȒƬɖȅƺȇɎɀِ ³z ژ ȇȒɎƺɀ ɎǝƏɎ Ɏǝƺ ǼǣƬƺȇɀƺƺ ǝƏɀ ǣȇǣɎǣƏɎƺƳ Ə ژ ȵǼƏȇ Ȓǔ ƏƬɎǣȒȇ ǣȇ Ɏǝǣɀ ȸƺɀȵƺƬɎ ƏȇƳ ɯǣǼǼ ƫƺ ƏɎɎƺȇɎǣɮƺ ɎȒ ژ Ɏǝƺ ژ ƳƺȵǼȒɵȅƺȇɎ Ȓǔ ȇƺɯ ȵȸƏƬɎǣƬƺɀ ǣȇ א ׎ א ׎ِ ASN considers that the licensee’s fire risk organisation is satisfactory. Orano Cycle must nevertheless ensure that the fire response times given in its nuclear safety case are in line with those observed during exercises. Furthermore, the licensee must improve the prioritising of the fire- fighting teams’ interventions. In 2020, ASN will remain attentive to the consistency between the intervention actions to accomplish and the human resources mobilised on the site. With regard to radiation protection, ASN notes that the organisation of the La Hague site and the results obtained are satisfactory, particularly with respect to dosimetry optimisation during work interventions. Random checks have nevertheless revealed delays on the performance of radiation protection technical controls, and insufficient rigour in the keeping of the entry registers for limited-stay areas and prohibited areas, and in tracking the mobile radiation monitors. ASN considers that the licensee’s environmental protection organisation is satisfactory. Orano Cycle must nevertheless increase the rigour of waste management in the facilities, particularly with regard to storage conditions and radiological checks. With regard to the management of the decommissioning and legacy waste retrieval and packaging projects, ASN considers that the organisation and project management must undergo fundamental improvements in order to meet the deadlines for the commitments made by Orano and transcribed in ASN requirements or decrees. ASN notes positively the integration of the lessons learned ǔȸȒȅ Ɏǝƺ ɀǣǼȒ ׏ ב ׎ ژ ȵȸȒǴƺƬɎ ɯǣɎǝ Ɏǝƺ Əǣȅ Ȓǔ ǣȅȵȸȒɮǣȇǕ Ɏǝƺ performance of the tests important to the safety for the HAO silo project and control of the fire risks in the project to retrieve the legacy waste from silo 115. The efforts must however be increased and widened. Orano must take all appropriate measures to allocate the necessary resources, whether internal or external, over the medium and long term in order to guarantee the effectiveness of its project management. Furthermore, ASN will ensure that Orano provides rigorous justification for the changes in scenario and durations of the associated operations, and will be attentive to the rigour of project management.
