The inspection scope and findings were summa"ized on December 2,.1985, with those persons indicated in, paragraph 1.above. The inspector described the areas inspected and discuss 3d thi inspection findings. -The licensee did not identify as proprietary any of the materials provided 'to or reviewed by the

inspectors during:the-inspectio . Onsite ' Followup of Events .and Subsequent Written Reports of Nonroutine-Events at Power Reactor Facilities (92700, 90714, 93792)',

For ' nonroutine : events selected for onsite followup, the inspectors

' determined that the licensee had taken corrective action (s) as stated in written' reports of the events and that these responses to the events were adequate and met regulatory requirements, license . conditions, and commitments. During the reporting period, the inspectors selected the following nonroutine events for onsite followup:

-(Closed) IFI 84-37-02 " COMMITMENT TO IMPLEMENT PROCEDURE CHANGE TO REQUIRE VERIFICATION OF ALL AUTO START / BLOCK FUNCTIONS OF LOAD SEQUENCERS." The Licensee implemented STP 125-011 and STP 125-010 to replace the old ST These new procedures verify the capability of load sequencer to energize component cooling pump "A" and to block auto start of certain " swing" pumps, (i.e. component cooling pump "C", service water pump "C" and charging pump

"C"). The corrective action appears to be adequate to satisfactorily-address the event and prevent recurrence. This item close .

Monthly Surveillance Observation (61726)

The inspectors observed surveillance activities of safety-related systems

'and components to ascertain that these activities were conducted in accordance with license requirements. The inspectors observed portions of selected surveillance tests including all aspects of one major surveillance test' involving safety-related systems. The inspectors determined that the

.-

p

. .

.

surveillance test ~ procedure conformed to Technical Specifications (TS)

requirements and verified that Limiting Conditions for Operations (LCO's)

.were met. a'nd ' that the surveillance test -was completed at the required frequency. The ) inspectors also verified that the required administrative approvals and t'agouts were obtained prior _to initiating the test, that the testing was ' accomplished by qualified -personnel in accordance with an a approved test procedure and that any required test instrumentation was properly calibrated. Upon completion of the testing, the inspectors observed that the~ recorded test data was accurate, complete and met TS requirements; verified any test discrepancies were properly rectified, and; independently verified that the systems were properly returned to service. The following specific surveillance activities were observed:

STP 445.007 -

MOVATS Testin STP 125.011 -

Train "B" Intergraded Safeguards Tes Within the areas inspected, no violations or deviations were identifie . Monthly Mainteriance Observation (62703)

-The inspectors observed maintenance activities of safety-related systems and components .to ascertain that these activities were conducted in accordance withf approved procedures, Technical Specifications (TS) and appropriate *

industry codes and standards. The inspectors determined that these activities were not violating Limiting Conditions for Operations (LCO's) and that redundant components were operable. The inspectors also determined (1)

that the procedures used were adequate to-control the activity, (2) that QC

hold -pointx were established where required, (3) that required administra-

.tive approvals and tagouts were obtained prior to work initiation, (4) that

_ proper radiological and appropriate ignition / fire prevention controls were implemented, and (5) that replacement r'r and materials used were properly

. certified. The inspectors verified teit t ese activities were accomplished by qualified personnel using al'reve, procedure The inspectors independently verified that equw;r unt s. properly tested before being returned U to service. Additionally, the inspectors reviewed several outstanding job orders to determine that the licensee was giving priority to safety-related maintenance and a backlog which might affect its performance was not developing on a - given system. The following specific maintenance activities were observed:

The-inspectors reviewed licensee progress _to ascertain whether pre-refueling activities specified in the Technical Specifications (TS) have 'been completed and whether refueling activities are being conducted as required by TS or approved procedures. Specifically, the inspectors.(1) verit'ied that all surveillance testing required by_the TS and licensee procedures for fuel handling had been ' completed prior to the handling of fuel in the core, (2)_

verified that the periodic testing of refueling related ' equipment is being

. performed as . required by TS or- licensee administrative procedures, (3)

6 ESF System Walkdown (71710)

The inspectors verified the operability of an engineered safety features (ESF) system by- performing a-walkdown of the accessible portions of the

- systems listed below. The inspectors confirmed that the licensee's system

. lineup procedures matched plant drawings and the as-built configuration. The inspectors looked for equipment conditions and items that might degrade performance (hangers and supports were operable, housekeeping, etc.) and

_ inspected the interiors of _ electrical and instrumentation cabinets for l debris, . loose material, jumpers, evidence of rodents, etc. The inspectors verified- that valves, including _ instrumentation isolation valves, were ;in

. proper position, power was available, and valves were locked as appropriat The inspectors compared both local and remote position indication , SOP 106 -

The inspectors observed licensee activities to ascertain that the facility-was being operated safely and in conformance with regulatory requirements, and'that the licensee's management control system is effectively-discharging its responsibilities for continued safe operation by direct observation of ~

activities,Ltours of the facility, interviews and discussions with licensee personnel , ; independent verification of safety system status- and limiting conditions for operation, and reviewing facility record STP 128.004 -

The inspectors reviewed licensee preparations for refueling including the adequacy of procedures and administrative controls for the refueling activities / outage and for the receipt of new fuel. As part of this activity, the inspectors verified that technically adequate, approved procedures were available covering (1) the receipt, inspection and storage of new fuel, (2)

fuel handling, transfers and core verification, (3) the inspection of fuel to be reused, and (4) the handling and inspection of any other core internal ,
