    Abstract

    This paper reports the results obtained in a Nordic Nuclear Safety Research project during the second intercomparison exercise for the determination of difficult to measure radionuclides in decommissioning waste. Eight laboratories participated by carrying out radiochemical analysis of 3H, 14C, 36Cl, 41Ca, 55Fe and 63Ni in an activated concrete. In addition, gamma emitters, namely 152Eu and 60Co, were analysed. The assigned values were derived from the submitted results according to ISO 13,528 standard and the performance assessments were determined using z scores. The measured results were compared with activation calculation result showing varying degree of comparability.

    Funding

    The authors would like to thank the Nordic Nuclear Research NKS-B programme (www.nks.org) for funding the DTM Decom project in which the intercomparison exercise was carried out. The authors would also like to thank the other participating laboratories, namely Technical University of Denmark, Cyclife Sweden AB, Fortum Power and Heat Oy, IFE Kjeller and IFE Halden for provision of data and collaboration. National fundings were given by Finnish Research Programme on Nuclear Waste Management KYT 2022. A-LABOS-EX-PR-SC-01 project is thanked for the CEA self-funding. The authors would also like to thank FiR1 decommissioning personnel for the provision of studied material and collaboration.
