In April 2016, Andra sent ASN the safety options file (DOS) for the Cigeo radioactive waste deep disposal project. Submission of a DOS means that the project becomes part of a process governed by the regulations concerning basic nuclear installations (BNI), more specifically by article 6 of the decree of 2 November 2007. ASN examined this file. In this respect, it requested an expert assessment from its technical support organisation, IRSN. It had this file assessed by the Advisory Committees of experts reporting to it. It also submitted it for review by experts from foreign safety regulators, coordinated by the IAEA. Following this technical examination phase, ASN consulted the public about its draft opinion from 1 August to 15 September 2017. After analysis of the contributions received, ASN issued its opinion on 11 January 2018. The management solution adopted in France for high level, or intermediate level long-lived radioactive waste (HLW/ILW-LL) is deep geological disposal. The Cigeo project aims to implement this principle as enshrined in law. ASN considers that the Cigeo project has on the whole achieved sufficient technical maturity at the safety options file stage. It also considers that the safety options file is documented and substantiated and constitutes a significant step forward with respect to the previous files submitted to ASN for its opinion.
