Nuclear safety analysis uses computer codes to predict the response of a nuclear power plant under a wide range of possible accident scenarios. Ensuring those predictions are trustworthy requires qualifying not only the computer code itself, but also the assumptions and decision choices behind scaling criteria, importance ranking, and even the selection of the validation test facilities. The entire method constitutes the Evaluation Model (EM) which must satisfy the EMDAP steps outlined in Regulatory Guide 1.203.
FPoliSolutions is a recognized industry leader at developing Evaluation Models. With a proven record in this field, FPS works on code development as well as code assessment following an exhaustive two-tier qualification strategy. Additionally, FPS provides modeling guidance for various nuclear power plant sub-systems consistent with current validation test facilities. These are just a few examples of the extensive work FPS performs on a daily basis in developing EMs for the nuclear industry.
Collaborating with the Idaho National Laboratory (INL), FPS is also at the forefront of developing strategies for handling 10 CFR 50.46c, which deals with an integrated ECCS/cladding acceptance criteria.
