Analysis of Core Physics Experiments on Fresh and Irradiated BR3 MOX Fuel in REBUS Program

Abstract: As part of an international experimental program REBUS, core physics experiments have been implemented on a UO 2 core, which consists of 3.3 and 4.0 wt% UO 2 fuel rods in a square pitch of 1.26 cm, and two partial MOX cores, which replace 7 Â 7 UO 2 fuel rods in the center of the UO 2 core by fuel bundles made of fresh BR3 MOX fuel or irradiated BR3 MOX fuel with an average burnup of 20 GWd/t. Burnup calculations of the BR3 MOX fuel were performed using a general-purpose neutronic calculation code SRAC, and co… Show more

“…The underestimation of the diffusion calculations with the SRAC code has been reported for some critical experiment analyses. 9,10) The diffusion coefficient determination method using the present method will be improved in the next step. P1 transport calculations were more accurate than P0 transport calculations; 2D transport calculations with axial buckling correction were sufficiently accurate as well.…”
