Validation of the Nodal Drift Method on a CANDU LOCA and First Application to the TWIGL Seed-Blanket REA
Abstract : The Nodal Drift Method (NDM) has been developed for a broad and coarse safety review of
promising thorium-fueled High Conversion Water Reactor (HCWR) options. Conceived as a missing link
between too approximate point kinetics and too sophisticated industrial codes, NDM is based on 2-group
diffusion theory and a lumped parameter model with maximized mesh size. It has been validated on a
CANDU LOCA (Loss Of Coolant Accident) benchmark, without any need for thermal calculations. With
same principle of pre-tabulated cross sections and as a first application to PWR-like REA (Rod Ejection
Accident), the well-known TWIGL benchmark of a ramp transient within a heterogeneous core has been
calculated. From its good results have been deduced a few perspectives towards future HCWR studies.
