Abstract

In this report is summarized the work performed in CHEMPC project. The aim in the project was to study the transport and chemistry of fission products in primary circuit and in containment during a hypothetical severe accident. The fission product chemistry in primary circuit was experimentally studied at VTT and at IRSN. The reactions on surfaces were also investigated. Experimental studies on fission product transport in SGTR sequences were conducted in international ARTIST and ARTIST-2 programs at PSI. The radiolytical oxidation of iodine in containment conditions was studied in co-operation with Chalmers University of Technology. Experiments were conducted both at VTT and at Chalmers. Based on previous experiments, modelling studies on the behaviour of ruthenium oxides in air-ingress accident were conducted. As a part of international co-operation, CHEMPC project included also 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 (SAFIR 2010), VTT, Nordic Nuclear Safety Research (NKS), Institut de Radioprotection et de Sûreté Nucléaire (IRSN) and Fortum Nuclear Services Ltd.
