issued on December 17, 1986, concerning activities conducted at your Catawba
-facility.
In regard to - Violation 50-413/86-45-01, failure to use calibrated
instrumentation for Techr ical Specification required surveillance, we have
evaluated your response ' and found that it meets the requirements of
We will examine the implementation of your corrective actions
during future inspections.
We have reviewed your response to Violations 50-413/86-45-02 and 50-414/86-48-01,
.
failure to provide adequate procedures for nuclear service water valve
verification, and have concluded, for the reasons presented in the enclosure to
,
this letter, that the violations occurred as stated in the Notice of Violation.
The NRC documented in the inspection report that manual valves in the service
water system were not verified in their correct position at least once per 31
days, and these valves were not locked, sealed, or otherwise secured as required
l
by the Technical Specifications.
Therefore, in accordance with the requirements
l
of 10 CFR 2.201, and within 30 days of the date of this letter, please submit a
(
supplemental response to the Notice. This response should include actions that you have
taken or planned to assure the adequacy of other valve verification surveillance
checklists.

ENCLOSURE
STAFF EVALUATION OF LICENSEE RESPONSE
DATED JANUARY 16, 1987
Violation "A" cites Technical Specification 4.7.4.a which requires that at least
two nuclear service water loops shall be demonstrated operable at least once per
31 days by verifying that each valve (manual, power operated, or automatic)
servicing safety-related equipment that is not locked, sealed, or otherwise
secured in position, is in its correct position.
The Duke Power Company response denies this violation on the following
contentions.
The Operations Management Procedure 2-19, Rounds Sheets,. requires
verification of pump seal, lubrication, and cooling water flows to operating
pumps twice each day.
This verification does not ensure that adequate flow
would be supplied to the non-operating pump on an emergency start.
The denial
states that inservice pumps are frequently rotated and that a review of plant
records for the last four months have confirmed this.
Objective evidence was
not presented that pumps were rotated at a frequency that would meet technical
specification requirements or that a valve lineup was performed that would
ensure proper valve position.
The denial also states that operators routinely
verify lubrication and . seal water flow rates to non-operating pumps.
This'is
not documented and cannot be considered an acceptable alternative for valve
verification.
The denial further states that indication exists in the control
room to warn the operator in the event that a nuclear service water pump is
started without adequate cooling water supply.
The indication is a high
temperature alarm and this may not be adequate to prevent damage to the pump
seals and bearings if the pump was started without cooling and seal water.
As stated in the inspection report, the seal water supply valves were not
included in the monthly valve verification procedure PT/1/A/4400/02C change 7.
The valves were not administratively controlled to ensure compliance with
Technical Specifications.
