With regard to the assessment of costs, and in the light of the DGEC’s competence with respect to monitoring and regulating the ring-fencing of funding for the long-term costs, ASN involved it in this oversight approach from the outset.

It first of all required a more detailed understanding of the baseline requirements and project management organisation at Orano. ASN underlines the licensee’s proactive attitude, which facilitated the discussions during the working meetings. In October 2019, ASN carried out an in-depth inspection Ȓȇ Ɏǝƺ (IJ ٢nȒɯ JȸƏȇɖǼȒȅƺɎȸɵ áƏɀɎƺ٣ ȵȸȒǴƺƬɎ ǣȇ zX ژבבژ ƏɎ…ȸƏȇȒ nƏ ژ RƏǕɖƺ ٢ȵǼƏȇɎ Ȩ גٮא ׎׎٣ِ Áǝǣɀ ȵȸȒǴƺƬɎ ƬȒȇɀǣɀɎɀ in retrieval of the filtration residues stored in settling tanks, units and pits in the former plant, their transfer and conditioning in a new building containing a waste homogeneous cementation treatment process.

This in-depth inspection was carried out with the DGEC, the Institute for Radioprotection and Nuclear Safety (IRSN) and the Cleanuc firm, a complex projects management expert. This inspection confirmed the benefits of new control methods applied to a complex decommissioning project. It also more clearly identified the numerous difficulties involved on many subjects with significant risk implications, along with fundamental areas for improvement. Furthermore, the results of this exploratory approach identified methods, currently still at the testing stage, enabling Orano to inform the authorities of the progress of its projects, notably through the development of new project monitoring and tracking tools. In 2020, ASN will assess the effectiveness of the changes implemented as a result of this inspection, notably with regard to monitoring the progress of projects at Orano. ASN will also be deploying this exploratory approach at EDF and French Alternative Energies and Atomic Energy Commission (CEA), with the same objectives, in order to ensure more global experience feedback. 340 ASN Report on the state of nuclear safety and radiation protection in France in 2019 ׏ ٲ ב DECOMMISSIONING OF BASIC NUCLEAR INSTALLATIONS
