Abstracts ASN Report 2021

especially unscheduled activities, and the management of deviations during works performance can be improved. In the area of occupational radiation protection, the year was marked by a deterioration in the radiation protection culture of workers, mainly outside contractors. An increase in situations of non-compliance with the elementary radiation protection measures, such as wearing a dosimeter, was observed. ASN has moreover regularly noted shortcomings in the risk analysis of work sites and in the implementation of the defences planned for by these analysis during maintenance activities, which have led in particular to internal exposures of workers. Effective measures are required in order to restore proper consideration of the radiation protection issues. With regard to environmental protection, ASN considers that the site’s good results of the preceding year have been conf irmed. The licensee must nevertheless be vigilant regarding control of the volume of waste present in the effluents treatment building. The labour inspection actions focused essentially on the conformity of the electrical installations and the prevention of the risk of falling from height. EDF must be particularly attentive to the meeting of commitments and to the compliance work on the electrical installations. Aube waste disposal facility Authorised by a Decree of 4 September 1989 and commissioned in January 1992, the Aube repository (CSA) took over from the Manche repository which ceased its activities in July 1994, while benef iting from the experience gained with the latter. This facility, located in Soulaines-Dhuys, has a disposal capacity of one million cubic metres (m3) of low and intermediate-level, short-lived waste (LL/ILW-SL). It constitutes BNI 149. The operations authorised in the facility include the packaging of waste, either by injecting mortar into metal containers of 5 or 10 m3 volume, or by compacting 200-litre drums. At the end of 2021, the volume of waste in the facility had reached about 363,000 m3, or 36% of the authorised capacity. According to the estimates made by Andra in 2016 in the concluding report on the CSA periodic safety review, the CSA could be completely f illed by 2062 rather than 2042 as initially forecast, this estimate being based not only on better knowledge of the future waste and the waste delivery schedules, but also an optimisation of waste management through the compacting of certain packages. In 2021, the activity of the centre facilities returned to normal (post-crisis due to the Covid-19 pandemic). The construction of new disposal structures for the future waste continued at the same time. ASN considers that the CSA is operated satisfactorily in the areas of safety, radiation protection and the environment. The inspections conducted in 2021 revealed more specifically: • satisfactory management of modif ications; • appropriate implementation of the commitments made concerning control of the f ire risk following the second periodic safety review; • the quality and rigour of the CSA’s dosimetric monitoring and the availability and regulatory conformity of the means of verif ication. Deep geological disposal repository project ASN considers that the scientif ic experiments and work conducted by Andra in the underground laboratory at Bure continued in 2021 with a good standard of quality, comparable with that of the preceding years. 62 ABSTRACTS – ASN Report on the state of nuclear safety and radiation protection in France in 2021 REGIONAL OVERVIEWOF NUCLEAR SAFETY AND RADIATION PROTECTION
