Availability Notice


The first fuel cycle of the BEAVRS PWR benchmark was simulated and analyzed. Models were prepared using the SCALE package, TRITON depletion sequence and NEWT as a lattice physics solver. A set of branch and burnup calculations were prepared, and group constants in the form of PMAXS libraries were generated using GenPMAXS for PARCS nodal diffusion core simulator. The hot zero power reactor physics measurement data and hot full power data were used to perform model validation simulations for the 1st fuel cycle. The core inventories for the BOC and EOC were calculated on the basis of PARCS and TRITON results with a dedicated computer code and compared with ORIGEN-ARP point burnup calculations.
