The Role of Swedish Universities in Supporting SSM Activities in the Field of Deterministic Safety Analysis

• Research within nuclear safety and radiation protection is necessary in order to maintain the high level of competence required by an expert authority. In the field of reactor safety research, SSM’s goals are to support regulation and contribute to national competence in the area of nuclear safety. A technical support organization on deterministic safety analysis (TSO-DSA) has been set up to help SSM in fulfilling these goals. The TSO-DSA function was then established by SSM at two nuclear universities, i.e. Royal Institute of Technology (KTH) in Stockholm and Chalmers University of Technology in Gothenburg. Activities related to this function have been performed, emphasizing the use of best-estimate coupled codes (i.e. PARCS/RELAP5 and PARCS/TRACE) for the analyse . The activities performed by Chalmers are reported in this paper as examples. The on-going activities give a good example on how the safety authority co-operates with universities. The use of coupled codes gives satisfactory results and in good agreements with measured data. Moreover, it may reveal some phenomena that are difficult to capture with stand-alone codes.
