NRC INSPECTION REPORT 50-275/95-01;
50-323/95-01
Thank you for your letter of May 5.
1995, in response
to NRC Inspection
Report 50-275/95-01;
50-323/95-01,
which discussed
our review of your motor-
operated
valve program developed in response to Generic Letter 89-10,
"Safety-
Related Motor-Operated
Valve Testing
and Surveillance,"
and requested
additional information regarding your Generic Letter 89-10 program.
In your May 5 letter, you described:
(1) your plans to apply the Electric
Power Research
Institute motor-operated
valve performance prediction
methodology to confirm your setup of the main feedwater
isolation valves.
and
the block valves for the power -operated relief valves;
(2) your formalization
of motor-operated
valve grouping following the guidance of Supplement
6 to
(3) your plans to continue to investigate the possible
effects of motor-operated
valve reassembly
using neolube
by a followup dynamic
test
on
a sample valve; (4).your periodic verification program,
including
static diagnostic testing
on two to six refueling cycle frequencies
and
dynamic diagnostic testing of nine motor-operated
valves over the next couple
of outages,
and your plans to evaluate
ASME guidelines
under development
for
your long-term motor -operated
valve program;
(5) your determination that at
least
5 percent
margin exists for valve factor degradation for each Generic Letter 89-10 motor-operated
valve;
and,
(6) closure of your quality assurance
audit findings related to the Generic Letter 89-10 program.
By telephone
on
July 18,
1995.
your staff notified the Office of Nuclear Reactor
Regulation
Project
Manager of the completion of your formalization of motor-operated
valve grouping using Supplement
6 to Generic Letter 89-10.
and your update of
appropriate
documents to reflect the valve factor degradation
allowance.
We found your May 5,
1995, letter to be responsive to our request.
Your plans
for periodic verification of motor-operated
valve design-basis
capability
sufficiently meet the intent of Generic Letter 89-10 for us to close our
review of your Generic Letter 89-10 program.
In the long term, the
NRC staff
is preparing
a generic letter specifically to addr ess periodic verification of
motor-operated
valve design-basis
capability that might recommend further
action in this area.
