SUBJECT:
NRC INTEGRATED INSPECTION REPORT NOS. 50-220/99-05
AND50<1 0/99-05
Dear Mr. Mueller:
This report transmits the findings of safety inspections conducted by NRC inspectors at the
Nine Mile Point Nuclear Station, Units 1 and 2, from May.9, through June 19, 1999. At the
conclusion of the inspection, the findings were discussed with members of your staff.
During the six-week inspection period covered by this report, operation of the Nine Mile Point
Nuclear Station reflected an acceptable safety focus.
Emergent work during the Unit 1 outage,
including the core shroud weld and tie rod repairs and recirculation piping weld examinations
were well controlled from a safety perspective.
At Unit 2, additional reactor core isolation
cooling {RCIC) system performance deficiencies were identified by your staff during on-line
maintenance.
We are concerned with the quality ofwork performed by the maintenance,
engineering and operations staffs which contributed to the RCIC system degradation.
Although
the specific issues were resolved, the underlying causes warrant additional attention.
ln accordance with 10CFR2.790 of the NRC's "Rules of Practice," a copy of this letter and its
enclosures will be placed in the NRC Public Document Room.
Sincerely,
Original Signed
