Abstract

More and more safety analyses are performed with coupled safety codes to assess in detail the reactor behaviour under abnormal conditions. The Canadian industry gives a particular attention to script-based or PVM-based coupling of reactor physics (RFSP) and thermalhydraulics (CATHENA or TUF) codes.

This work presents a first step to develop independent simulation capabilities using a script-based coupling of DONJON and CATHENA codes. This work aims to provide CNSC with a tool allowing for have independent  insights related to  CANDU reactors behaviour under  different  anticipated transients or accidents involving reactor physics and thermalhydraulics. A particular interest is being given to the assessment of the impact of RIH break opening time on the power pulse for a generic CANDU-6 reactor.
