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.

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.
