ASN Report 2020

changes to regulations, or on a general nuclear safety or radiation protection topic. As an expert assessment body, the members of the Advisory Committees are required to abide by the provisions of the external expert assessment charter in Appendix 2 to the ASN internal rules of procedure. Each member of an Advisory Committee draws up a declaration of interest (which is made public in the particular case of the GPMED which deals with health products questions, in accordance with the health expert assessment charter of 21 May 2013 as set out in Article L. 1452-2 of the Public Health Code). The provisions concerning the prevention of conflicts of interest were reinforced at the end of 2019, with the adoption of the new internal regulations common to the eight GPEs. More specifically, an organisation was defined for identifying ties and conflicts of interest and for dealing with them in an appropriate manner. Since 2009, as part of its commitment to transparency in nuclear safety and radiation protection, ASN has published the GPE letters of referral, the opinions of the GPEs and ASN's position statements based on these opinions. The IRSN for its part publishes the summaries of the technical investigation reports it presents to the GPEs. Advisory Committee for Decommissioning (GPDEM) Chaired by Michèle Viala, the GPDEM comprises 33 experts appointed for their competence in the field of BNI decommission­ ing. The GPDEM was consulted once with regard to the decom­ missioning project for the Phébus facility. This consultation will continue in 2021. Advisory Committee for Waste (GPD) The Advisory Committee for Waste (GPD) is chaired by Pierre Bérest and comprises 38 experts appointed for their competence in the nuclear, geological and mining fields. An on-line information meeting was held in 2020, jointly with Andra and the IRSN. The GPD was thus consulted on several topics, including bituminous waste. Advisory Committee for Nuclear Pressure Equipment (GPESPN) Since 2009, the GPESPN has replaced the Standing Nuclear Section of the CCAP. This latter was replaced as of 28 December 2016 by a standing sub-committee of the CSPRT (see point 2.4.3). The GPESPN has been chaired by Matthieu Schuler since 6 October 2018 and comprises 29 experts appointed for their competence in the field of pressure equipment. In 2020, it held two plenary meetings, including the final meeting which closed the file on the in-service resistance of the 900 Megawatts electric (MWe) reactor pressure vessels. It was asked to take part in the meeting of the GPR on the results of the 4th periodic safety review of the 900 MWe reactors. Advisory Committee for Radiation Protection in Medical and Forensic Applications of Ionising Radiation (GPMED) Chaired by Bernard Aubert, the GPMED comprises 36 experts appointed for their competence in the field of radiation protection of health professionals, the general public and patients and for medical and forensic applications of ionising radiation. In 2020, it held two plenary meetings, one of which was organised jointly with the GPRADE. A call for candidates will be issued during the course of 2021, in preparation for the renewal of the Committee scheduled for December 2021.
