EVENT TEXT
THIS PART 21 INVOLVES RECEIVING A REFURBISHED DB-25 CIRCUIT BREAKER
WITH
A MISSING PART.
THE LICENSEE RECEIVED A REFURBISHED DB-25 CIRCUIT
BREAKER(REFURBISHED IN
1992) FROM WESTINGHOUSE REPLACEMENT COMPONENTS SERVICES,
MONROEVILLE, PA.
THE REFURBISHED BREAKER WAS RETURNED TO THE LICENSEE WITH A MISSING
PIN
IN THE OPERATING MECHANISM. THE ABSENCE OF THIS PIN IS BELIEVED TO
HAVE
CONTRIBUTED TO THE FAILURE OF THE "SWP1B" CIRCUIT BREAKER TO CLOSE
ON A
MANUAL SIGNAL FROM THE MAIN CONTROL BOARD. THIS ALSO IMPLIES THAT
THE
POTENTIAL EXISTS FOR THE BREAKER NOT TO CLOSE ON AN AUTOMATIC
DEMAND AND
THEREFORE NOT BE AVAILABLE TO PERFORM ITS SAFETY FUNCTIONS. THERE
ARE 41
PERMANENTLY INSTALLED DB-25 BREAKERS IN THE SCREEN HOUSE AND
TURBINE
BUILDINGS AT THE SITE. ALL OF THE REMAINING BREAKERS WERE VISUALLY
INSPECTED TO VERIFY THE PIN IN QUESTION WAS INSTALLED. NO OTHER
BREAKERS
WERE FOUND TO BE MISSING THE PIN.
THE RESIDENT INSPECTOR WAS NOTIFIED.

10CFR21 INITIAL FACSIMILE NOTIFICATION
I. NAME AND ADDRESS OF THE INDIVIDUAL INFORMING THE COMMISSIONS
NAME: Joseph A. Widay
ADDRESS: Rochester Gas & Electric Corporation
89 East Avenue
Rochester, New York 14649
II. IDENTIFICATION OF THE FACILITY, THE ACTIVITY, OR THE BASIC
COMPONENT SUPPLIED FOR SUCH FACILITY WHICH FAILS TO COMPLY OR
CONTAINS A DEFECT:
The facility is the R.E. Ginna Nuclear Power Plant. The basic
component is a Westinghouse DB-25 circuit breaker. This component
was installed at Ginna Station in a Class 1E Safety Related 480 Volt
AC bus. The breaker was the power supply feed breaker for the "B"
Service Water Pump (52/SWP1B).
III. IDENTIFICATION OF THE FIRM CONSTRUCTING THE FACILITY OR
SUPPLYING THE BASIC COMPONENT WHICH FAILS TO COMPLY OR
CONTAINS
A DEFECT:
The DB-25 circuit breaker were refurbished by:
Westinghouse Replacement Component Services
Westinghouse Electric Corporation
Nuclear Services Division
Haymaker and Northern Pike Road
Monroeville, PA 15146
The current refurbishment site is:
Westinghouse Electric Corporation
Assembly & Test Facility
Cheswick Site
2000 Cheswick Avenue
Cheswick, PA 15024-1358
IV. NATURE OF THE DEFECT OR FAILURE TO COMPLY AND THE SAFETY
HAZARD
WHICH IS CREATED OR COULD BE CREATED BY SUCH DEFECT OR FAILURE
TO COMPLY:
The refurbished DE-25 circuit breaker was returned to Ginna Station
with a missing pin in the operating mechanism. The absence of this
pin is believed to have contributed to the failure of the SWP1B
circuit breaker to close on a manual signal from the Main Control
Board. This implies that the potential exists that the breaker
would not close on an auto demand and therefore not be available to
perform its safety functions.

V. THE DATE ON WHICH THE INFORMATION OF SUCH DEFECT OR FAILURE TO
COMPLY WAS OBTAINED:
The information was obtained on May 13, 1998. An attempt was made
to start the "B" Service Water Pump during testing and it failed to
close on a manual signal from the Main Control Board. During the
troubleshooting the missing part was discovered.
VI. IN THE CASE OF A BASIC COMPONENT WHICH CONTAINS A DEFECT OR
FAILS TO COMPLY, THE NUMBER AND LOCATION.OF ALL SUCH
COMPONENTS
IN USE AT, SUPPLIED FOR, OR BEING SUPPLIED FOR GINNA STATION:
There are forty-one, permanently installed DB-25 breakers in the
Screen House and Turbine Buildings at Ginna Station. Of these,
eleven breakers are Class 1E Safety Related.
VII. THE CORRECTIVE ACTION WHICH HAS BEEN, IS BEING, OR WILL BE
TAKEN; THE NAME OF THE INDIVIDUAL OR ORGANIZATION RESPONSIBLE
FOR THE ACTION; AND THE LENGTH OF TIME THAT HAS BEEN OR WILL BE
TAKEN TO COMPLETE THE ACTION:
A spare DB-25 circuit breaker was inspected, tested and installed to
restore the "B" Service Water Pump to service.
All of the remaining DB-25 breakers were visually inspected to
verify that the pin in question was installed. No other breakers
were found to be missing the pin.
VIII. ANY ADVICE RELATED TO THE DEFECT OR FAILURE TO COMPLY ABOUT
THE
FACILITY, ACTIVITY, OR BASIC COMPONENT THAT HAS BEEN, IS BEING,
OR WILL BE GIVEN TO PURCHASERS OR LICENSEES:
Both in-service and receipt inspections can verify the presence of
the pin in question. It should be noted that the "B" Service Water
Pump breaker was refurbished in 1992.
