To avoid coinciding outages between its two sister units, American Electric Power Service Company (AEPSC) decided to operate one of its units in a reduced power mode and extend its cycle length an additional 500 MWd/tonne U. The unit is a four-loop Westinghouse reactor consisting of 193 17 x 17 fuel assemblies and generating 3411 MW(thermal) at full power. A previous study considered the reactor physics effects of extended reduced power operation (RPO) on some specific reactivity parameters and peaking factors. This cycle-specific analysis assessed the impacts of RPO, for as much as 11,600 MWd/tonne U, on safety parameters by re-evaluating the complete reload safety analysis checklist and the results are discussed in this report. The analysis used the Westinghouse PHOENIX-P/ANC methodology.
