SMR FUEL CYCLE OPTIMIZATION AND CONTROL ROD DEPLETION USING NESTLE AND LWROPT

摘要

The multi-cycle BWR fuel cycle optimization code BWROPT has been generalized to handle PWRs and SMRs and renamed LWROpt (Light Water Reactor Optimizer) and an eighth core symmetric shuffle option has also been implemented. The new features of the optimizer are tested using a test case based on an SMR model previously developed manually. Also, preliminary tests of a spatially-dependent and movable-region isotopic tracking feature under development in NESTLE are illustrated with the ultimate goal of assessing control rod depletion for very long SMR rodded cycles.
