Status of SOPHAEROS Fission-Product Transport Code Validation

Abstract

The IPSN (France) code SOPHAEROS has been selected to simulate FP transport and deposition in the PHTS for CANDU safety and licensing analysis. SOPHAEROS 2.0 was acquired by AECL on behalf of COG and will be validated for heat transport system conditions representative of several CANDU accident scenarios. The validation plan is summarized in this paper. SOPHAEROS 2.0 simulations offifteen phenomena will be validated using thirty validation data sets. The first sets of data to be used for the validation are BTF-104 and FALCON FAL-ISP. A brief description of these experiments is provided, along with the status of the validation work.
