Abstract

COSYMA is a probabilistic accident consequence assessment system, for use in calculating the risk posed by potential nuclear accidents involving a release to atmosphere, taking into account the range of conditions which may prevail at the time of the accident. It was developed by the National Radiological Protection Board (UK) and the Forschungszentrum Karlsruhe (Germany) as a part of the Commission's European MARIA project. A simplified version of the system has been implemented on a personal computer. The system is primarily intended for routine users of the COSYMA code who do not generally want access to the more complex features included in the full version of the COSYMA. It can be used for deterministic or probabilistic assessments. Deterministic assessments give detailed results for a single set of atmospheric conditions, probabilistic assessments give results taking account of the full range of atmospheric conditions, probabilistic assessments give results taking account of the full range of atmospheric conditions and their respective frequency of occurrence. The report describes the second version of the system. The main improvements over version 1 are the incorporation of graphical presentation of the results, more detailed presentation of results of deterministic calculations and the calculation of the economic costs of the accident. This report replaces the earlier report (EUR 14916) describing version 1 of PC COSYMA.
