4, Unresolved Items No unresolved items were identified during this inspection.
Plant erations The inspector kept informed on a daily basis on the overall plant operating status and any significant safety matters related to plant operations. Daily discussions were held with plant management and members of the operations staff. Selected portions of the various daily operating journals and data sheets were reviewed on at least a weekly basis during the report period.
The inspector made plant tours on the following dates: 2/8, 2/16, 2/22, 2/27 and 2/28. Selected areas of the turbine building, reactor buildings and outside areas were visited. The control rooms were visited on a more frequent basis than other areas of the plant.
Observations included work activities in progress, valve positions, status of operating and standby safety systems, >nubbers, instrument readings and recordings, panel indications, housekeeping and vital areas controls.
The tour of 2/28 was in the company of the plant electrical engineer whose responsibilities include overview of the fire protection alarm and automatic initiation systems. Emphasis was placed on valve line ups and operability of alarms and automatic controls for protection of safety-related equipment.
I H Informal discussions were held with operators and other personnel on work activities in progress and status of safety-related equipment or systems. The inspector's questions were satisfactorily answered.
Shift change was observed in the control rooms on 2/7 and,2/21. On the latter date shutdown of Unit 2 was observed in the control room.
On 2/27 startup operations including subcritical rod withdrawal and bringing the reactor critical were witnessed by the inspector. An unannounced visit to observe operations was also made on 2/19 which was a holiday. On all the above occasions, the Technical Specifica-tions staffing requirements were met.
No item of noncompliance or deviations were identified by the inspector.
Re ortable Occurrences Review The below listed licensee event reports were reviewed to determine if the information provided met NRC reporting requirements. The determi-nation included adequacy of event description and corrective action taken or planned, existence of potential generic problems and the relative safety significance.

- 7. Plant erations Review Committee (PORC)
The functions and activities of the PORC, which serves as the onsite review committee, -were reviewed for the period September 6,- 1978 through February 15, 1979 to determine conformance to Technical Speci-fications requirements and the Charter described in the Operational Quality Assurance Manual. Meeting minutes confirmed that meetings were conducted with a quorum of qualified members present within the required frequency. Items coming before the Committee included among other things, new procedures, procedure revisions, corrective section reports, Licensee Events Reports, Scram Reports, Work Plans, Proposed Technical Specification changes, License Amendments, nonconforming items, test reports and noncompliance items.
Xn addition to reviewing the records of PORC the inspector interviewed various members of the Committee on selected topics. All the inspector's question were satisfactorily answered.
- 8. Plant Dewaterin S stem E
Repairs "and modifications to the plant dewatering system, which were accomplished during the report period, were followed by the inspector.
Simultaneous failure of both dewatering pumps had led to building in-leakage problems as described in a previous inspection report (lE Report 50-259/79-4).
By the end of this report period, "B" well had a new stainless steel liner installed inside the concrete casing and the electric pump had been rebuilt with subsequent satisfactory performance. A new larger-diameter well, also with a stainless steel liner, had been sunk nearby.
This well currently has a diesel driven pump installed which test operated satisfactorily. Final determination of the type of pump for this well has not been made. This well has been designated as standby to "B" well. "A" well which had suffered casing damage will be aban-doned due to reluctance to attempt clean-out because of its close proximity to "B" well.
A program of test well drilling is under consideration to learn more about the underground water paths and the advisability of sinking additional dewatering wells. Recent experience following a heavy rainstorm has demonstrated that no in-leakage problem developed with the current system.
- 9. Plant Ph sical Protection The inspector observed on a routine basis personnel badging, searching, escort, and vehicle and escort control practices. Vital area controls were also observed. No items of noncompliance or deviations were identified.
