Abstract:

Following the Fukushima Daiichi nuclear accident, CNSC staff identified the need for detailed computational models to analyze highly unlikely severe accident scenarios involving an irradiated fuel bay (IFB).

This presentation will start by summarizing the foundational work on an IFB phenomena and key parameter identification and ranking table (PKPIRT), which determined that the development of an analysis code was feasible and that an adequate knowledge base existed.

The presentation will then discuss the development and capabilities of the IFB severe accident code BAYLOCA, a lumped parameter code that can generate results quickly to meet the requirements of CNSC emergency operations centre processes and is sophisticated enough to also be used to inform regulatory decisions.
