摘要

The objective of this Department of Energy sponsored program is to demonstrate increased burnup in 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 program includes a demonstration of advanced fuel designs to a batch average discharge exposure of 53 GWD/T and of the current fuel design to a batch average discharge exposure of 43 GWD/T. Analyses are included to assure that the high burnup objective can be realized with both conventional and low leakage fuel management schemes. This report describes the design, fabrication, characterization and incorporation into two ANO-2 Batch D fuel assemblies, of fuel rods which employ three advanced fuel concepts. These concepts include grahitel-coated Zircaloy cladding, annular fuel pellets and large-grained fuel pellets. It is expected that these design modifications will eventually allow batch average fuel burnups in excess of 53 GWD/T. (ERA citation 07:050166)
