Follow-up Item (309/79-06-02).
the inspector reviewed the licensee's progress in this area. During a safeguards valve position verification on January 22, 1981, five valves were found not to have identifying labels. These valves were identified to the Operations Department Head for corrective action (CS-7, CS-8, CS-103, CS-104, SIA-44).
It was noted that all valves outside containment had been properly labeled. The labels on the above valves will be rechecked during a subsequent inspection.
l (Closed) Follow-up Item (309/79-10-01). The NRC Health Physics Appraisal feam evaluated the licensee's Respiratory Protection Pro-gram.
Based on their satisfactory finding the inspector had no further questions in this area.
(Closed) Unresolved Item (309/79-14-06).
Licensee procedures 5-27 Reassembly of a Reactor Coolant Pump; and 5-28, Installation of a Reactor Coolant Pump Motor were reviewed, approved and issued as of 12/1/80.
(Closed) Follow-up Item (309/79-19-02). The NRC Health Physics Appraisal Team evaluated the waste shipping program and identified no significant weaknesses. The 1979 annual audit discrepancies have been corrected. The inspector had no further questions 11 this area.

Follow-up Item (309/79-19-03). The inspector determined that the Chemistry / Health Physics Training Program had been initiated in response to the 1979 audit report. The NRC Health Physics Appraisal Team evaluated this training program.
Based on the satisfactory eval-uation of this program, the inspector had no further questions in this area.
(Closed)
Follow-up Item (309/79-19-04). The inspector determined that training sessions have been conducted pertaining to NRC and D0T requirements. The NRC Health Physics Appraisal Team evaluated this area and found it satisfactory. The inspector had no further questions in this area.
(Closed) Unresolved Item (309/80-02-02). The NRC Health Physics Appraisal Team evaluated the air sampling capability of the licensee.
Based on the satisfactory evaluation of this team and the incorpora-tion of new alpha spectroscopic equipment on site, the inspector de-termined that the licensee's air sampling capability is adequate.
The inspector ned no further questions in this area.
(Closed)
Follow-up Item (309/80-10-02). The inspector verified that the locally posted procedures had been incorporated into the controlled document distribution. No further questions were identified.
(Closed) Unresolved Item (309/80-12-03). The inspector reviewed I & C surveillance procedures.
Each calibration procedure has been retyped and reissued. The new data sheets are legible.
No further quastions were identified.
(Closed)
Noncompliance item (309/80-13-ul). The inspector reviewed the licensee's procedure 9-1-15, Snipment of Madioactive Material Rev 7. January 1981.
Precautions and verifications have been added to preclude recurrence of this event. The inspector has observed shipments leaving the site to verify proper marking.
No further instances of improper labels were identified.
(Closed) Follow-up Item (309/80-14-01). The inspector reviewed the corrective action taken with respect to this item. Operator training in this area revealed that cycling of locked valves after this verifi-cation is required procedurally in order to recirculate the sample safeguards system piping. Operators are however still responsible for returning valves to the proper locked position. Subsequent valve line-up verifications were performed by the inspector with no discre-pancies identified. Tne inspector had no further questions in this area.

3.
Review of Plant Operations - Plant Inspections The inspector reviewed plant operation through direct observation throughout the reporting period, a.
Instrumentation Control room process instruments were observed for correlation between channels and for conformance with Technical Specification requirements.
No unacceptable conditions were identified.
b.
Annunciator Alarms The inspector observed various alarm conditions which had been received and acknowledged. These conditions were discussed with shift personnel who were knowledgeable of the alarms and actions required.
During plant inspections, the inspector observed the condition of equipment associated with various alarms.
(1) Heat Tracing The inspector noted that the heat tracing malfunction alarm on the main control board is continuously in the alarmed state due to malfunction of non-safety related heat tracing circuits.
Since routine surveillance of local heat tracing e. arm panels is not accomplished, the licensee has no means to verify the operability of safety related heat tracing circuits required
!
by Technical Specification 3.5.
The inspector found no l
required heat tracing out of service. This issue is unresolved pending licensee action on interim measures to monitor safety l
related heat tracing while the annunciator is invalid.
(309/81-03-01).
c.
Shift Manning The operating shifts were observed to be staffed to meet the operating requirements of Technical Specifications, Section 5, both to the number and type of licenses. Control room and shift manning were observed to be in conformance with 10 CFR 50.54.

Primary Component Cooling Pumps P9A and P9B were placed out of service one at a time on January 23, 1981 for preventive mainten-ance. Each pump remained out of service for more than two hours.
i Pump P9A was placed out of service for corrective maintenance on January 26, 1981 and remained out of service for 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />. Tech-nical Specification 3.6 requires two redundant safeguards trains
to be operable during power operation and specifies "one component i
cooling pump" per train. This specification allows unlimited operation with one of the two pumps available in each train out of service. The secondary component cooling (SCC) system is especially sensitive as it supplies cooling for both emergency diesel generators. Operation (as permitted by Technical Specifi-cations) with only one SCC pump in service places the plant in i
the situation that a single failure of either the remaining SCC pump or its associated diesel generator would disable both safe-guards trains.
In response to the inspectors' concerns, the licen-
,
l see is proposing several changes in the component cooling systems, including supplying cooling water for one diesel generator from the primary component cooling (PCC) system and rearranging pump
-
power supplies. The licensee intends to accomplish these modifi-cations during the next refueling outage. The licensee proposed to take interim measures to verify operability of the diesel generators daily while any component cooling pump is out of service.
The adequacy of the design of the component cooling system and the current Technical Specifications has been referred to IE Headquarters for evaluation (AITS F01004861 ).
This issue is
>
unresolved pending IE/NRR review of the recomended action.
(309/81-03-02).
b.
The inspector witnessed the performance of surveillance testing of selected components to verify that the surveillance te-1 pro-
,
i cedure was properly approved and in use; test instrumentation required by the procedure was calibrated and in use; technical specifications were satisfied prior to removal of the system l
from service; test was performed by qualified personnel; the procedure was adequately detailed to assure performance of a satisfactory surveillance; and, test results satisfied the pro-cedural acceptance criteria, or were properly dispositioned.
