Sedapsim Reactor Systems Analyzer for Design and Beyond Design Basis Accident Conditions

Abstract

SCDAPSIM is being developed as part of an international SCDAP Development and Training Program. SCDAPSIM is designed to provide a detailed, mechanistic prediction of the response of a reactor system during design basis and beyond design basis accident conditions. SCDAPSIM is the result of merging models from SCDAP/RELAP5 with state-of-the-art containment and source term models. The objectives of this paper are to (a) describe the goals of the SCDAP Development and Training Program, (b) briefly outline the overall capabilities of SCDAPSIM, (c) describe the advantages of the SCDAPSIM modeling approaches, and (d) discuss the application of SCDAPSIM to the CANDU reactor design.
