Operational Safety Verification The inspector observed control room operations, reviewed applicable logs and conducted discussions with control room operators during the month of July 198 The inspector verified the operability of selected emergency systems, reviewed tagout records and verified proper return to service of affected component Tours of contain-ment, auxiliary and turbine buildings were conducted to observe plant equipment conditions, including potential fire hazards, fluid leaks,. and excessive vibrations and to verify that maintenance requests had been initiated for equipment in need of maintenanc The inspector by observation and direct interview verified that the physical security plan was being implemented in accordance with the station security pla A tour of the security fence was conducte The inspector observed plant housekeeping/cleanliness conditions and verified implementation of radiation protection control During the month, the inspector independently verified system lineups for operability using licensee checklists on the iodine removal system,

the alternate shutdown panel (C-33), and the emergency diesel generator system The inspector also witnessed portions of the radioactive waste systems controls and independently surveyed a radwaste truck awaiting shipmen The following items were identified and brought to the attention of appropriate licensee personnel as a result of various inspection tour Cigarette butts were noted in a non-smoking area (cable spreading room) and accumulated on the floor at an entrance to the radiation controlled are Trash bags marked "Caution - Radioactive Material" were being used for and stored as noncontaminated trash in one of the emergency diesel room On July 31 the inspector determined the monthly fire extinquisher inspection was incomplet When notified, the licensee assigned personnel sufficent to complete the inspections as require These items were also discussed at the management intervie The plant was shut down on July 11 and remained in the cold shutdown condition throughout the remainder of the month while repairs and general maintenance were completed, particularly on a primary coolant pump sea Two events occurred during the shutdown period which were specifically reviewed by the inspector. First, on July 14, an in-advertent safety injection actuation was activated on the "right" channe The breaker to Inverter No. 2 opened (for reasons not determined) causing loss of power to the vital 120 v. panel carrying one low-pressure SIS relay and associated SIS bloc When power was restored, the SIS relay actuated before the block could be re-estab-lishe The only effect on the plant was a brief primary system boratio The "right" LPSI pump was operating in the shutdown cooling mode and was unaffected, while all HPSI pumps were disabled as required for shutdown overpressure protection and could not actuat Normal conditions were restored in a matter of minutes and NRC was notified pursuant to 10 CFR 50.7 The second event involved a loss of shutdown cooling capability for about 1. 5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> on July 18 when the shutdown heat exchanger outlet valve failed closed with water in its control air syste Alternate cooling means were available but proved unnecessary as the licensee iden-tified and corrected the problem before primary system temperatures reached 200° Personnel were staged as a precaution to isolate the containment building equipment hatch should it have become necessar Core flow was maintained throughout the even In each of the above circumstances, the licensee's response actions were both timely and appropriat On July 30, the licensee notified NRC a corporate daily audit of plant activities as specified in an NRC Order dated March 9, 1981, had not been completed the previous da A description of the circumstances will be provided to NRC in writing, including proposed corrective actions, and will be reviewed during a future inspectio \\'
At the end of the month of July 1981, the licensee was preparing for plant startu The inspector reviewed numerous Equipment Outage Request packages and licensee-completed checklists to verify proper return to service of systems and components prior to the startu The above reviews and observations were conducted to verify that facility operations activities were in conformance with the require-ments established under technical specifications, 10 CFR, and controlling procedure No items of noncompliance or deviations were identifie.
Monthly Maintenance Observation Station maintenance activities of safety related systems and components listed below were observed/reviewed to ascertain that they were conducted in accordance with approved procedures, regulatory guides and industry codes or standards and in conformance with technical specification The following items were considered during this review:
the limiting conditions for operation were met while components or systems were removed from service; approvals were obtained prior to initiating the work; activities were accomplished using approved procedures and were inspected as applicable; functional testing and/or calibrations were performed prior to returning components or systems to service; quality control records were maintained; activities were accomplished by qualified personnel; parts and materials used were properly certified; radiological controls were implemented; and, fire prevention controls were implemente Replacement of an air-start motor on emergency diesel-generator 1-Primary water storage tank level instrument calibratio Preventive maintenance on breaker 152-10 Replacement of control rod drive mechanism seal Changeout of "A" primary coolant pump seal, including hydrostatic stand testing of the replacement sea Replacement of secondary position indication string No items of noncompliance or deviations were identifie Monthly Surveillance Observation The inspector observed technical specifications required surveillance testing on the systems/components identified below, and verified that testing was performed in accordance with adequate procedures, that test instrumentation was calibrated, that limiting conditions for

- operation were met, that removal and restoration of the affected components were accomplished, that test results conformed with technical specifications and procedure requirements and were reviewed by personnel other than the individual directing the test, and that any deficiencies identified during the testing were properly reviewed and resolved by appropriate management personne The inspector examined portions of the following test activities:
MI-2 MC-11 Q0-10 R0-32 Reactor Protective Trip Units Safeguards Boron Samples Containment Isolation Check Valve Test Procedure Containment Building Penetration Local Leak Rate Test (equipment hatch)
Complete data for several tests performed in June and July were re-viewed. During this time the licensee developed and was initiating new requirements for review of surveillance procedures in response 1 2 to noncompliances/problems identified in previous inspection reports.-/_/
While the new systems were still being put into effect, a test procedure was once again improperly reviewed, a situation that may be corrected as the new review process is fully implemente M0-24
"Inservice Test Procedure (Auxiliary Feedwater Pumps)" was reviewed by a shift supervisor and the steam driven auxiliary feedwater pump declared operable despite data (which the licensee now believes erroneous) showing the pump was inoperabl This mistake was dis-covered by an independent review and appropriate corrective action was taken, but the second review was not completed until seven days after the error was mad Implementation of the review process revisions, including new timeli-ness requirements, will be examined in followup to the noncompliance previously note No items of noncompliance or deviations were identifie.
Preparations for Refueling This inspection included a review of licensee procedures for the planned 1981 refueling outage, including review of the licensee's system for overall outage contro Approved procedures were judged technically adequate in the following specific areas: Fuel handling and transfers 1/
