SUBJECT:
NINE MILE POINT UNIT 2 CIRCUIT BREAKER INSPECTION REPORT
NO. 50-410/98-18
Dear Mr. Mueller:
This letter refers to a circuit breaker team inspection conducted from September
21 - 25,
1998 at Nine Mile Point Unit 2. The purpose of the inspection was to determine whether
activities authorized by the license were conducted safely, and in accordance with NRC
requirements.
At the conclusion of the on-site inspection on September 25, 1998, the
findings were discussed with members of your staff.
Additional findings from information
provided by your staff subsequent to the on-site inspection were discussed with Mr. G.
Gresock on October 14, 1998.
The inspection was directed toward areas important to public health and safety.
The areas
examined during this inspection included your medium-voltage and low-voltage circuit
breaker maintenance
pro'gram, maintenance
procedures,
voltage calculations, operating
experience review, vendor manual and interface programs, circuit breaker testing, and self-
assessment
audits.
Within these areas, the inspection consisted of selective examinations
of procedures
and representative
records, interviews with personnel,
and observation of
activities in progress.
Although the overall breaker maintenance
program was acceptable, the team determined
that there were several areas of weakness
in the program.
These areas were identified by
your staff during recent self-assessment
audits, including the vendor interface program for
breaker maintenance, the controls of breaker vendor manuals, the "periodic re-contact" of
breaker vendors, and the operating experience review program.
The self-assessment
audits reflected good identification of problem areas.
The NRC team identified additional examples which confirmed weaknesses
in those areas.
Of particular concern is the area of operating experience review, Some reviews were
found to contain incorrect conclusions due to incomplete database
searches
and personnel
not familiar with plant equipment; others were narrowly focused and did not consider
generic applicability. Weak operating experience reviews resulted in missed opportunities
to prevent breaker failures in the past.
