Subject:

EXTENSION OF FORCED OUTAGE On January 15, 1988, the licensee informed the resident inspectors and the NRC Operation Center that the present unplanned outage to inspect and repair feedwater system components and supports (see PN0 I-87-117 dated December 21,1987) would be extended approximately three weeks to perform an inspection of the bushings in the reactor vessel flange, which hold the six-inch diameter reactor vessel head studs.

During the week ending 1/9 the licensee also learned that several ten year ISI inspections,' which had been scheduled for the 1986 refueling outage, were either missed or inappropriately deferred. The majority of these were weld inspections, and the licensee states that these have since been performed. An inspection of the reactor vessel flange bushings, required by ASME Code, should have been performed in 1981 when all of the head studs were replaced. The licensee has begun preparations to rezove the vessel head to perform the inspections. The licensee has not yet determined whether the 1988 refueling outage, scheduled to begin in March, will begin early or be postponed until the summer of 1988.

The resident inspectors are onsite reviewing licensee actions. This PN is issued for information only. The State of New York has been notified.
