_P_lant Operations a.
Logs and Records Weekly reviews did not identify any areas of concern.
b.
Tours _of the Plant The inspector conducted tours of accessible areas of the plant to observe monitoring instrumentation, radiatiou controls.
- housekeeping conditions, fluid leaks, piping vibrations, selected valve and switch positions, and hold tags. The inspector also verified control room manning and equipment status and inspected for fire hazards.
No areas of concern were identified. The inspector noted minor flange and valve packing leaks that had been identified for repair and verified that radiation control procedures had been implemented where required.

Redirtion Protection a.
Exposur d ntrol The inspector examined several radiation work permits (RWP's)
and observed work being performed. No deficiencies were identified.
'
b.
_ Posting and Control Posting of high radiation areas (areas with dose rates between 100 mrem /hr and 1 Rem /hr.) showed some inconsistencies.
Soce areas with " hot spots" greater than 100 eRec/hr were designated as high radiation areas, although the area measurement
"whole body dose rate" was less than 100 mrem /hr. The licensee reviewed the RWP's and redesignated those that were over-conservative.
- The inspector observed that one RWP for a high radiation area i
did not designate a requirement for radiation monitor that continuously indicates the radiation dose rate, bewever, the operators authorized to enter the area are routinely required to wear the constant indicating monitor. The licensee took
,
inmediate action to add the requirement to the RWP.
No items of noncompliance were identified.
4.
Cleanliness The inspector reviewed the licensee's procedures for control of tools and access during refueling and for general control of housekeeping activities.
.
The inspector toured the accessible areas of the plant including Unit I containment and shield building. Housekeeping was good in all areas, with exception of storage of some scaffolding in the
'
Unit 1 shield building. The licensee plans to remove the scaffolding to be used during the upcoming Unit 2 refueling outage, and will provide a storage area in the auxiliary building.
No items of noncompliance were identified.
5.
Securin
,
The inspector conducted periodic observations of access control, issuing of badges, vehicle inspection, escorting, and communications checks.
.
No items of noncompliance were identified.

The inspector reviewed several work requests (WR's) and work request authorizations (WRA's) and verified that all required reviews and approvals had been completed. The inspector witnessed completion of work authorized by WRA-BS252-2CQ, to remeve actuators from Unit 1 Tan Coil Unit Discharge Dacper No. CD34078, verified that all Technical Specification requirements for testing redundant systems was cocpleted, and verified that system operability requirements were maintained.
The inspector observed preparations for containment entry, radiation survey and monitoring during the maintenance activity and surveys of components removed from containment. No areas of concern were identified.
