The inspector observed plant operations during six offshifts during the month of April, 1979 The inspector also made visual observations of the roccine surveillance and functional tests in progress during the period. This review was conducted to verify that facility operations were in conformance with the requirements established under Technical Specifications, 10 CFR, and Administrative Procedures.

A review of the licensee's deviation reports for the period was conducted to verify that no violatiens of the licensee's Technical Specifications were made.

The inspector conducted a tour of Units 1, 2 and 3 reactor bui'. dings and turbine bui3 dings throughout the period

8.

Review of Plant Operations Prior to Startup after Refueling Outage, Unit 2 The inspector verified that plans existed to test the primary cooling system, nuclear instrumentation system, feedwater system, control rod drive system, and emergency core cooling systems which underwent maintenance or were disturbed during the refueling outage and that the plant startup procedures require adherence to the licensee's Technical Specifications and commitments, as they pertain to startup testing and power operation prerequisites.

No items of noncompliance or deviations were identified.

9.

Review and Followup on Licensee Event Reports Through direct observations, discussions with licensee person-nel, and review of records, the following event reporta were reviewed to determine that reportability requirements were fulfilled, immediate corrective action was accomplished, and corrective action to prevent recurrence had been accomplished in accordance with Technical Specifications.

-5-353 085

.

Unit 1 LER 78-24, Backup diesel generator inoperative due to failure of fuel oil transfer pump.

Unit 2 LER 78-23, HPCI system isolated and declared inoper-ative during surveillance testing.

LER 78-35, Fuel storage racks cracked.

LER 73-45, Auto blowdown switch, PS 2-1430-1466D, failed to trip within Technical Speci-fication limits.

LER 78-57, Core spray system flow test valve, 2-1402-4B, failed to shut against pump pressure.

LER 78-68, Recirculation system discha ge bypass valve breaker tripped.

LER 79-01, Torus level in excess of Technical Specification limits.

LER 79-02, HPCI failed to start.

LER-79-03, LPCI/ Core spray pump discharge on auto blowdown permissive, PS 2-1430-1466D, tripped in excess of Technical Specifi-cation limits.

LER 79-04, LPCI full flow test valve, MO-2-1501-38A, failed.

LER 79-05, "D" Main steamline radiation monitor failed.

LER 79-08, LPCI minimum flow valve failed to shut.

LER 79-09, Loss of stack gas monitor.

LER 79-13, Unit 2/3 DG cooling water pump failure.

-6-353 086

.

LER 79-14, Unit 2 DG failed to start.

LER 79-15, Generic loss of reactivity on control rod blades.

LER 79-16, Crack on 1 inch drain line on LPCI System.

LER 79-17, Containment isolation valves, A0-2-1601-23, 24, 60, 61 and 63, leakage exceeded Technical Specification limits.

Regarding LER 79-01, the inspector determined that on January 3, 1979 the maximum level in the torus as specified by Technical Specifications Section 3.7.A.1 was exceeded while troubleshooting a failure of the motor speed changer on the HPCI system.

The inspector further determined the cause of exceeding Limiting Condition for Operation was personnel error rather than an inadequate procedure, as was reported by the licensee on January 31, 1979.

The licensee agreed to change to event report to indicate personnel error.

The cause of personnel error was attributed to his attention being directed to the operation of the HPCI turbine during repeated starting and stopping and the lack of continued monitoring of the torus level. This is considered an item of noncompliance (237/79-12-01).

The licensee has cautioned operators on the importance of continuous monitoring of torus level during HPCI system testing and has initiated procedure changes to delineate more explicitly maximum and minimum levels to be maintained in the torus and to specifically caution the operator when evolu-tions are in progress which could affect torus level. The inspector has no further concerns on this matter. We will review the procedure changes when they have been completed.

Unit 3 LER 79-01, Main steamline high flow isolation switch, DPIS 3-261-2C, trip exceeded Technical Specification limits.

LER 79-03, Main steamline radiation monitor failed.

LER 79-04, Failure to perform full core scram testing on two control ~ rod drives.

Regarding LER 79-04, the licensee determined during a quality assurance audit that control rod drives H-8 and K-8 were not-7-353 087

scram tested on May r 1978, as is required by Technical Specifications 4.3.C.I.

Corrective actions to prevent recurrence have been completed. This is considered a licensee identified item.

No items of noncompliance or deviations were identified, e: cept as previously described.

10.

Refueling Activities, Unit 2 The inspector verified that prior to the handling of fuel in the core, all surveillance testing required by the Technical Specifications and licensee's procedures had been completed; verified that during the outage the periodic testing of refueling related equipment was performed as required by Technical Specifications; observed all shifts of the fuel handling operations (removal, inspection and insertion) and verified the activities were performed in accordance with the Technical Specifications and approved procedures; verified that containment integrity was maintained as required by Technical Specifications; verified that good housekeeping was maintained on the refueling area; and, verified that staffing during refueling was in accordance with Technical Specifications and approved procedures.

No items of noncompliance or deviations were identified.

11.

Surveillance of Safety Related Systems /Cemponents Required by Technical Specifications The inspector observed Technical Specifications required sur-veillance testing (other than calibrations and checks) on the emergency core cooling system, Automatic Depressurization System (ADS) and High Pressure Coolant Injection (HPCI) system and verified that testing was performed in accordance with technically adequate procedures, that test results were in conformance with Technical Specifications and procedure requirements and were reviewed by personnel other than the individual directing the test, and that any deficiencies identified during testing were properly reviewed and resolved by appropriate management personnel.

No items of noncompliance or deviations were identified.

12.

Calibration of Safety Related Components Required by Technical Specifications The inspector observed calibration of the high drywell pressure emergency core cooling and isolation pressure switches (DIS 1600-4) and verified conformance with Technical Specifications and use of a technically adequate procedure.

No items of noncompliance or deviations were identified.

13.

Exit Interview The inspector met with licensee representatives (denoted in Paragraph 1) on April 6, 20 and 27, 1979, and summarized the scope and findings of that weeks' inspection activities.

The licensee acknowledged the item of noncompliance discussed on April 27, 1979.
