Optimum fuel rod dimensions

Description

ABB Combustion Engineering (ABB CE) evaluated two fuel rod designs with different moderator-to-fuel ratios: (1) a standard ABB CE rod for 16 X 16 fuel with high uranium loading: value-added pellets, and (2) a thinner rod with reduced clad surface area, clad thickness, and uranium loading: here called the 16 X 16 OFA (optimized fuel assembly). It is well known that all pressurized water reactors are under-moderated; this ensures a negative moderator temperature coefficient (MTC). Increasing the lattice moderation is thus expected to improve uranium utilization while having a detrimental effect on MTC. This study was performed to quantify the uranium utilization benefit and other effects of increased moderation
