At present, more than one quarter of the BNIs ٢ ژדב ȒɖɎ Ȓǔ ׏ דא ٣ Əȸƺ ɀǝɖɎƳȒɯȇ Ȓȸ ƫƺǣȇǕ ƳǣɀȅƏȇɎǼƺƳِ ASN observes numerous delays in the decommissioning projects. There would appear to be a number of reasons for this: technical and organisational difficulties, human and financial resources allocated, etc. However, since 2015, the TECV Act has stipulated “ decommissioning as rapidly as possible ” after shutdown of the facility. One of the specific features of assessing the decommissioning dossiers is that the safety issues in these facilities differ from those of the facilities in service. These issues concern the waste recovery and dismantling operations themselves, which are sometimes complex and which sometimes require the workers to intervene in close proximity to hazardous substances, but also the speed at which they progress. The time associated with reduction of the source term is a significant component in the safety of these facilities, which frequently do not meet current safety standards. The robustness of the strategy and the ability of the licensee to carry out its project on-time are therefore important factors ǣȇ ژ Ɏǝƺ ɀƏǔƺɎɵ Ȓǔ Ɏǝƺ ǔƏƬǣǼǣɎǣƺɀ ƫƺǣȇǕ ƳƺƬȒȅȅǣɀɀǣȒȇƺƳِ The analysis of these dossiers thus requires expertise appropriate to the specific features and the competence of the experts making up the GPDEM reflect this need. For example, some members of the GPDEM have specific project management skills. Owing to their composition and their skills, the Advisory Committees can offer the critical perspective needed for the drafting of their opinions, in order to inform the decisions taken by ASN on the regulatory dossiers submitted to it on the occasion of the major milestones in the life of the BNIs (creation, commissioning, decommissioning). Their opinion is drafted on the basis of technical debates and the judgement of their experts regarding the organisations and processes of the licensees. In their debates, the Advisory Committees can draw on the IRSN opinion presented during specific sessions in the ASN premises (lasting one or more days). In February 2019, the GPDEM met for the first time to examine the periodic safety review conclusions report ƏȇƳ Ɏǝƺ ƳƺƬȒȅȅǣɀɀǣȒȇǣȇǕ ƳȒɀɀǣƺȸ ǔȒȸ zX ٫ או ³ȒǼǣƳ áƏɀɎƺ Management Zone (ZGDS) in CEA’s Saclay centre.
