    Abstract

    This report summarizes the activities performed in CHEMPC project. The aim of the project was to study transport and chemistry of fission products in primary circuit as well as in containment during a hypothetical severe accident. Experimental studies on fission product chemistry in primary circuit were conducted at VTT and at IRSN. Fission product transport in SGTR sequences was experimentally studied in international ARTIST program at PSI. Experiments on radiolytic oxidation of iodine in containment conditions were carried out together with Chalmers University of Technology at VTT. Based on previous experiments, modelling studies on the behaviour of ruthenium oxides in air-ingress accident were conducted. As a part of international collaboration, CHEMPC project also included follow-up of Phebus FP and ISTP programs as well as ISTC program project EVAN. CHEMPC project is funded by Finnish Research Programme on Nuclear Power Plant Safety 2007-2010 (SAFIR2010), VTT, Nordic Nuclear Safety Research (NKS), Institut de Radioprotection et de Sûreté Nucléaire (IRSN) and Fortum Nuclear Services Ltd.
