Westronics, an instrument vendor, reports that certain Westronics Series
CSVC "Smartview" nuclear safety-related videographic recorders need
hardware modifications to ensure accurate measurement if they are used to
measure temperatures from thermocouple inputs.  The hardware
modifications require installation of capacitors associated with the
Dallas 1620 Temperature Compensation Chips.  Instruments requiring the
modification were shipped between July 16, 1998 and July 7, 2000.
Affected nuclear power plants include River Bend, Shearon Harris, and
Brunswick.

The vendor's stated that affected customers will be notified in
accordance with the requirements of 10 CFR Part 21.

The NRC will post ensuing reports on this subject on its website at
http://www.nrc.gov/NRC/PUBLIC/PART21/2000.

Subject: TURBINE DRIVEN AUXILIARY FEEDWATER PUMP FAILURE

Discussion:

On November 28, 2000, the turbine driven auxiliary feedwater (AFW) pump
failed to rotate when control room operators attempted to start the pump.
The AFW pump had been operated briefly, approximately 30 minutes earlier,
with normal shaft rotation observed.

The pump was partially disassembled and a cap screw from the hydraulic
balancing drum was found broken.  Further analysis determined that the
cap screw head had dislodged and wedged between the rotating balance drum
and the stationary housing causing the pump shaft to bind. The hydraulic
balancing drum contains a total of four (4) cap screws which were
subsequently replaced and the pump was successfully post maintenance
tested at on November 30.

Preliminary failure analysis indicated corrosion fatigue as the primary
cause of the cap screw failure.  The licensee determined that the cap
screw material did not match the vendor specification, and that the
applied torque as specified by the vendor and described in the
maintenance procedure may have been too high.  The licensee staff
investigation is continuing.

Regional Action:

The resident inspectors observed the repair activities associated with
the auxiliary feedwater pump and continue to monitor the licensee's
investigation.
