Development of a Graphical Animation Interactive Feature to Assess MAAP-CANDU Simulation Results

Abstract

MAAP-CANDU is an integrated severe accident analysis code for CANDU plant simulations that necessitates the assessment and post-processing of extensive amounts of information obtained from code run results. The MAAP-CANDU GRaphical Animation Package Extension (GRAPE) is a flexible, efficient, interactive and integrated visualization tool for analyzing plant behaviour during postulated accidents including accident management actions for single and multi-unit CANDU plants. GRAPE was developed by FAI in consultation with CNL (AECL) and CNSC from the FAI MAAP-GRAAPH code used in MAAP (LWR version). CNSC plans to use MAAP-CANDU and GRAPE as one of the tools in their Emergency Operations Centre‎.
