5o -JlJ CENTRAL FlLES 5)1~/efJ PALISADES END-OF-YEAR REPORT 1977 A.
Significant Events B.
The plant operated routinely during 1977 with the exception of routine maintenance items and three occurrences caused by loss of offsite power to the plant in September (LER 77-47), November (LER 77-55), and December (LER 77-58) due to a single lockout relay malfunction on the "R" (345 KV) bus supplying the plant from the switchyard.
The apparent safety concerns were forwarded to Headquarters for review.
The plant received authorization to increase power from 2200 MWt to 2530 MWt on November 1, 1977.
The plant performed the required testing and increased power to 2530 MWt on November 6, 1977.
The licensee has commenced the spent fuel pool (safety related) modifications and the addition of*a full flow condensate polishing system (nonsafety related).
Both the major modifications are due to by completed in 1978.

Inspector's Evaluation of Licensee Performance The overall performance of the Palisades plant appears to be satisfactory; but with noted areas requiring improvement:
- 1.
Full implementation of training and retraining for all plant personnel during 1978 (excluding licensed personnel training).
- 2.
Continuing pursuit of the many outstanding maintenance items which detract from the overall maintenance program.
(Discussed at the management meeting in October 1977.)
- 3.
Overall management controls appear to need improvement.
- a.
During the period of August 13-16, 1977, the plant continued to be operated even though the containment purge exhaust valve leakage exceeded the allowable (La).
(Discussed at the manage-ment meeting in October 1977.)
- b.
During the repair of the containment exhaust purge valve, the seat was sealed with an unauthorized sealant to reduce the leakage and no *safety evaluation was provided in accordance with 10 CFR 50.59.
(Discussed at the management meeting in October 1977.)
- c.
The essential instrument bus Y-01 was powered from the emergency bus without a safety evaluation as required by 10 CFR 50:59.
Palisades 3 -
- d.
Safety related surveillance procedures were modified in late 1976 and a Technical Specifications requirement was overlooked and not performed until November 1977, subsequent to an NRC audit.
- e.
The safety injection tank level switches were not maintained in the operable status resulting in the loss of water level in one tank for an indeterminate period of time.
- f.
The iodine removal system was placed into service without adequate assurance that the system was fully operational and subsequent to direct questioning by the NRC inspector, the system was discovered in the degraded mode.
- g.
The licensee continues to fail to meet commitments.
The commitment date for completion of corrective actions concerning plant 'Security training and retraining passed without completion.
The item remains open and the item of noncompliance will be closed during 1978.
- h.
The number of significant personnel errors at the plant are a continuing problem, as noted in the next section of this report.
These items specifically detract from the plant performance.
Also, the items of noncompliance concerning personnel errors and inadequate management controls are negative indicators to an operating plant.
D.
Personnel Errors No significant personnel errors occurred resulting in an event which had the potential to significantly affect the health and safety of the public.
The routine inspection requirements revealed no significant personnel errors which resulted in an event which had the potential to significantly affect the public.
Several licensee events reported were attributed to personnel errors.
- 1.
ER 77-08
- 2.
ER 77-23 1/17/77 4/19/77 Following feedwater pump trip, operator attempted to avert reactor trip by manually running in control rods, but did not switch mode selector from auto to manual resulting in one rod being driven in below the group.
Waste gas decay tank overpressured and while isolated, tank loss in violation of TS limits.

The iodine removal system (hydrazene) was placed into service with the circuit to one of the hydrazene tank outlet valves inoperable.

ER 77-64 12/1/77 HPSI pump removed from service without functionally testing the other HPSI pump to verify operability.
E.
Sununary of Unplanned Radioactive Releases Two events occurred during the year resulting in unplanned released.
- 1.
Event Report 50-255/77-23, 4/19/77, was issued as a result of a small release of radioactive gas from a waste gas decay tank due to personnel error.
The release was not detectable on the stack gas monitoring system and the calculated release was approximately 3.6 Curies of gas; primarily Xenon 133.
(IE Inspection Report No. 50-255/77-13)
- 2.
Event Report 50-255/77-56, 11/29/77, was issued as a result of a small release of radioactive gas subsequent to the tripping of the main exhaust fans during a normal release activity.
The release was 5.2 millicuries total; 0.088 microcuries of 1-131.
The procedures have been subsequently revised to assure cessation of a gaseous release when the main exhaust fans trip.
(IE Inspection Report No. 50-255/77-18)
