Abstracts

The research presented here focuses on simulating approach-to-critical experiment of Experimental Breeder Reactor II using DIF3D computer code and applying Modified Source Multiplication method. Historical EBR-II approach-to-critical measured data was obtained from Argonne National Laboratory reports. The dry and wet critical experiment reports include reactor fuel loading configurations, neutron source and detector locations, and count rates of each detector. Traditional approach-to-critical experiment of EBR-II was simulated, and neutron flux and adjoint flux were calculated by using DIF3D. The MSM correction factor was calculated. The measured 1/M data was corrected. Finally, the improvement factor (IF) was developed to assist in confirming the improvement from ASM to MSM.
