Management Interviews Licensee Action on.Previous Inspection Findings Not inspected.
Unresolved Items No unresolved items were identified during this inspection.
Plant Operations The inspector kept informed on a daily basis of the overall plant status and any significant safety matters related to plant operations.
Daily discussions were held with plant management and various members of the plant operations staff.
Frequent visits were made to the shift engineers'ffice and control rooms to review current reactor operating status and activities.
Special visits were made to other locations in the plant to observe activities and to verify system or component statu Selected portions of the daily journals and other operating records were reviewed on at least a weekly basis during the report period.
The inspector made general plant tours on November 30 and December 3, 1979.
Selected areas in the turbine building, reactor buildings and outside areas were visited.
Observations included witnessing work activities in progress, status of operating and standby safety systems, valve positions, snubber condition, instrument readings and recordings, annunciator alarms, house-keeping, radiation area controls and vital area controls.
Informal
'discussions were held with operators and other personnel about work activities and equipment status.
Some of the specific activities observed were:
a.
Unit 2 control room operations following a reactor trip due to a flux spike on November 29, 1979.
Recording charts and log entries were reviewed and discussion held with control room operations personnel.
b.
Unit 2 control room operations involving return to power operations on November 30 1979.
c.
Unit 3 instrumentation readings during the hydrostatic test of the primary system on November 30, 1979.
d.
Portions of the Unit 3 startup from the refueling outage ending on December 6,
1979.
Included were low level power operations from cold conditions to operating conditions.
e.
Shift turnover in the Unit 2 control room on November 29 and 30, 1979.
No items of noncompliance or deviations were identified by the inspector in
,the above areas.

The inspector's questions were satisfactorily answered.
7.
Special Operator Training The inspector reviewed with the Training Coordinator the content of the special training provided to licensed operators for Unit 3, prior to startup from the recent refueling outage.
The training covered modifications to the LPCI system, the new accoustical monitoring system in the main steam relief valves and modifications to the controls on certain primary containment isolation valves.
All affected licensed personnel received the subject training prior to December 6,
1979.
8.
Plant Physical Protection During the course of routine inspection activities, the inspector made observations of certain plant physical protection activites.
These included personnel badging, personnel search and escort, vehicle search and escort, vital area access control and physical barriers.
No items of noncompliance or deviations were note I 0
