- Denotes those attending exit interview.
The inspectors also talked with and interviewed other licensee employees
.
during the inspection.
These employees included licensed and unlicensed
'
operators, craftsmen, engineers and office personnel.
2.
Operational Safety Verification
.
The inspectors performed certain activities to ascertain that the facility is being operated safely and in conformance with regulatory requirements
and that the licensee's management controi system is errectively dis-
,
li charging its responsibilities for continued safe operation.
The inspectors activities and findings in this regard are described in the following para-graphs:
I a.
Inspection Activities Performed Several Times Per Week
,
(1) Control room observations were made which included the following items:
(a) Licensee adherence to selectr Limiting Conditions for Operations (LC0's).
(b) Observation of instrument and recorder traces for abnormalities.
'
i (c) Verification of operator adherence to approved procedures.
(d) Verification of control room and shift manning.
(2) Review of selected logs and records to obtain information on plant operations, trends, compliance with regulatory require-
'
ments, and assess the effectiveness of communication provided by these logs and records.
(3) During the course of control room observations the inspectors
-
noted the alarm status of the control room annunciators.
The alarm status was discussed with several licensed operators to i

2 determine the cause for the alarm conditions.
The inspectors determined as a result of these discussions that for the plant status these alarms were normal and the operating staff is cog-
,
nizant of the cause for the alarms.
b.
Insoection Activities Performed on a Weekly Basis l
(1) Th2 operability of selected Emergency Safeguards Features
(ESF) systems was verified by noting valve positions, breaker t
positions, instrumentation and the general condition of
!
majorsystem components.
In addition, the NRC inspectors performed a complete walk down of the following systems, using the licensee's approved valve line-up sheets:
t Lrw Pressure Safety Injection System
Engineered Safeguards Controls (2) The licensee's equipment control was reviewed for proper implementation by performing the following inspection activities:
(a) Review of maintenance order log and tag-out log to determine the licensee's compliance with LCO's and Technical Specifications action statements.
(b) Verification of " Return to operable status of selected safety-related components and systems."
-
(3) The inspectors toured accessible areas of the plant at
!
various times during the inspection to determine and/or verify equipment conditions, plant conditions, security, safety and housekeeping.
Observations included the following:
(a) General plant and equipment condition.
.
(b) Fire hazards.
(c) Control of combustible material.
(d) Fire watch postings and presence of fire watches when required.
(e) Physical security.
The inspector verified that the security plan is being implemented by observing that:

Isolation Zones are clear.
.
Vehicles are properly authorized, searched, and
.
escorted or controlled within the protected area.
Persons within the protected area display photo
.
identification badges and persons requiring escort are properly escorted.
Vital area physical barriers are not degraded.
.
Persons and packages are checked prior to entry into
.
the protected area.
The inspectors observed several shift turnovers and reviewed several shift turnover sheets.
No violations or deviations were identified.
3.
Surveillance Observations a.
The inspectors observed portions of the following surveillance test:
ST-ISI-CC-3, Rev. 8, 2/18/81, " Component Cooling Water Pump
.
Inservice Testing", item F.1.
b.
The inspectors determined through personal observatio?s and records, j
as appropriate that:
(1) Approved procedures were used.
(2) Test instrumentation was calibrated.
(3) Limiting Conditions for Operation were met when the system being tested was removed from service.
(4) The test data was recorded accurately and completely.
Selected test results were independently verified by the inspector.
(5) The surveillance test documentation was properly reviewed and test discrepancies were rectified.
)
(6) Test results met Technical Specification requirements.

4.
Maintenance Obser,:tions a.
The inspectors observed portions of the following maintenance activities:
RPS "B" channel was placed out of service on June 24 because ( t) channel power indication was down approximately 157,, (2) T was swingingerratically,and(3)sub-marginmonitorwasinalarm.hkain-tenance Order (MO) 10648 was written and approved to c.rform main-tenance on this channel.
The inspector verified th the test equip-ment being used was in. calibration.
Once repairs were completed, the inspector verified that the M0 was signed off properly and that the appropriate surveillance procedure was performed and witnessed by QC after maintenance.
Charging pump CH-1B was placed out of service for overhaul due to a history of excessive leakage that has caused packing to be replaced frequently.
MO 10555 was written and a-oved to perform this maintenance, and the pump was tagged Jr. der tagout no.81-448 which was verified by the inspector.
inspector observed work in progress after the pump was alra assembled, and observed a dye penetrant test being conu 'teo s
,ie pump block.
No violations or deviations were identi';ed.
5.
Follow up on IE Bulletins The inspector reviewed the licensee's responses to verify that:
a.
The written response was within the time specified.
b.
The written response addressed the information required.
c.
Adequate corrective action, when required, was specified.
d.
Corrective action was accon ished as specified.
