The assessment of containment codes by experiments simulating severe accident scenarios
The experimental background to the behaviour of containment under severe accident conditions is summarised, including a description of the main features of important containment test facilities. Scaling and operational procedures of the available test facilities are important factors in the suitability of experimental data for code validation purposes. A provisional code validation matrix based on a careful selection of experiments performed during past years in relevant test facilities, under various operating conditions, is proposed. The execution of code validation based on the proposed matrix would complement code validation findings obtained in previous ISP (International Standard Problem) activities, performed under the umbrella of CSNI/OECD or the CEC. The code validation matrix focusses on the thermohydraulic aspects of the containment behaviour as an important first step. Past code application activities have shown that most problems may be traced back to inaccurate thermohydraulic parameters governing gas or aerosol distribution events.
