Evaluation and Demonstration of Methods for Improved Nuclear Fuel Utilization: Tenth Progress Report, July 1, 1985-December 31, 1986

摘要

The objective of this Department of Energy sponsored project is to demonstrate the extended burnup capability for Combustion Engineering 16 x 16 fuel. A demonstration of this is in progress at the Arkansas Nuclear One Unit 2 (ANO-2) reactor located near Russellville, Arkansas. This reactor is a 2815 MWt pressurized water reactor (PWR) owned and operated by Arkansas Power and Light. It is the first Combustion Engineering reactor to utilize the 16 x 16 fuel design. The extended burnup objective will be realized by demonstrating that the current fuel design is capable of increasing batch average exposure at discharge to 52 GWd/MtU and by evaluating advanced fuel designs with the potential to offer increased performance margins over the current design at similar discharge exposures. Analyses are included to assure that the extended burnup objective can be realized with conventional and low leakage fuel management schemes. During this period, test Assembly D040, which contains standard fuel rods and rods with advanced fuel designs, was visually and dimensionally examined during the EOC-5 refueling outage of ANO-2. The assembly was then reinserted into Reactor Cycle 6 for a 5th exposure cycle. 12 refs., 8 figs., 1 tab. (ERA citation 13:008788)
