Research Fellow Nivedita S attended the annual meeting of the OSPAR’s Radioactive Substances Committee (RSC) held from 8 to 10 February 2022. She was part of the delegation of the Advisory Committee on Protection of the Sea (ACOPS), a non-governmental organisation with observer status with the OSPAR Commission. Held virtually, the main focus of this meeting was to finalise the fifth periodic evaluation (5PE) and the Radioactive Substances Thematic Assessment for the Quality Status Report 2023. The purpose of such evaluations is to analyse the progress made by Contracting Parties to the OSPAR Convention towards the strategic objective of the OSPAR Radioactive Substances Strategy, which aims to reduce discharges of radioactive substances to the North-East Atlantic either to background values or near zero. Strategic issues that the RSC monitors include floating nuclear power stations. The International Atomic Energy Agency and the World Nuclear Association also attended as observers.
