Abstract

The Canadian Super Critical Water Reactor design was simulated using G4STORK. The results of the simulation showed the expected trends but the determined Keff of 1.253±0.003 with a Coolant Void Reactivity (CVR) of -25mk differed greatly from the results achieved using MCNP of Keff=1.2914 and a CVR of -14mk. This discrepancy is partly due to the different data libraries used and the mixing of different temperature libraries in MCNP but is also likely due to a difference in the physics methodology. Work is ongoing to further clarify reasons for discrepancies and improve the efficiency of the simulation.
