Description

The DB-MHR (Deep Burn-Modular Helium Reactor) concept was proposed by GA to achieve a very high burnup of the LWR TRU fuel. Instead of the original 3- fuel-ring concept, the candidate DB-MHR core was modified to use the 5-fuel-ring configuration for a higher discharge burnup. This study intends to characterize the decay heat impact on the maximum transient fuel temperature of the various TRU compositions. The volumetric packing fractions (PF) of 4.9%, 5.9% and 6.9% are applied for the TRISO of (0.2%UO2+99.8%(PuO1.8+NpO2)+ 0.6mole SiC getter) and the PFs of 7.0% and 8.0% are used for the TRISO of (30%UO2+70%(PuO1.8+NpO2)+ 0.6mole SiC getter), respectively, with the kernel diameter of 350 μm and the buffer layer thickness of 100 μm
