SUMMARY
OF OPERATING EXPERIENCE UNIT TWO MAY, 1983 5-1 to 5-3 Unit Two entered the. month operating at a power level of 543 MWe but shortly thereafter the "B" feedwater check valve developed a gasket leak' causing'the unit to be shutdown.
5-4 to 5-31 Following repair of the leaking gasket, the unit was returned to power and operated continuously the remainder of the month (with normal power reductions on weekends for surveillances),
reaching a power level of 826 MWe with a capacity factor of 80.79% and an availability of 94.02%.
