.The inspection scope and findings were summarized on January 31, 1986, with those persons indicated in paragraph I above. The inspector described the areas inspected and discussed.the 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)

For nonroutine events selected for onsite followup, the inspectors deter-mined 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 commitment During the reporting period, nonroutine events were reported and the inspectors selected the following for onsite followup: (0 pen) Special Report -(SPR.85-021). The reactor building containment tendon third period surveillance completed on December 18, 1985

identified 's'everal tendons where the lift off forces were less than

. required by Technical' Specifications (TS) 4.6.1.6.1(b). Tendons found to be below the TS requirements were retensioned to within acceptable values. A long term evaluation is still in process with an anticipated-complete date of late 1986. This item was reported to Region II on January 17, 1986. The item remains ope .

2 (0 pen) LER 85-03 On Decembei- 25, -1985, Pressurizer Spray Valve PCV4440, failed in the' open position. This resulted in rapid system depressurization of the Reactor Coolant System (RCS) with a manual reactor trip. and an automatic safety injectio This item was discussed in inspection report 85-46 and identified as an unresolved item (UNR 85-46-01). A report on this event was submitted to Region II on January 24, 1986. _The inspector has reviewed the short term corrective actio The item remains open to review the long term corrective actio (Closed) Special Report (SPR 84-007). The inspector reviewed the documentation .and corrective action taken by the licensee and they appear to be satisfactory. This item is close (Closed) Special Report (SPR 84-011). The inspector reviewed the licensees documentation and corrective action on this item. They appear to be adequate.to preclude recurrence. This item is close Within the areas inspected, no violations or deviations were identifie ' Monthly Surveillance Observation (61726)

The inspectors observed suriail".ance activities of safety-related systems and components to ascertain Mt these activities were conducted in accordance with procedure and license requirements. The inspectors observed portions of selected surveillance tests including all aspects of one majo surveillance test involving safety related system The inspectors also verified that the required administrative approvals were obtained prior to initiating the test, that the testing was accomplished by qualified personnel, that required test instrumentation was properly calibrated, that data met TS requirements, that test discrepancies were properly rectified, and independently verified that the systems were properly returned to service. The following specific surveillance activities were observed:

STP 145.003 Gaseous Radwaste Treatment and Ventilation Exhaust Treatment System Operability Test STP 125.002 Diesel Generator Operability Test STP 133.001 Axial Flux Difference Calculation STP 134.001 Shutdown Margin Within the areas inspected, no violations or deviations were identifie . Monthly Maintenance U servation (62703)

The inspectors observed maintenance activities of safety-related systems and components to ascertain that these activities were conducted in accordance with approved procedures, TS and appropriate industry codes and standards. The inspectors also. determined that the procedures used were

The inspector reviewed the action taken by the licensee in response to IE 4 Information Notice No. 85-94, Potential for loss of Minimum Flow Paths

' Leading to ECCS Pump Damage During a LOC A review of the applicable systems at Summer by the licensee and the resident inspector determined that

,

this notice could be applicable to the Charging and Volume Control System (CVCS), Residual Heat Removal (RHR), and Emergency' Feedwater-(EFW). System The CVCS system, which is also the high head safety injection system, has an individual motor operated valve fcr each pump and a motor operated valve in the common.line that goes to the seal water heat exchanger and then to the Volume Control tank. These are normally open valves with main control board

' indication. To preclude operating the pumps with a valve / valves shut, instruction have been provided to the operators which require that they declare the pump inoperable if the valve / valves or shut for any reason. The

notice has not been completed. The interim steps taken by the licensee is considered acceptable. The inspector will review the licensee's final resolution and actions taken on this notice when it is complete Within the areas inspected, no violations or deviations were identifie . ESF System Walkdown (71710)

The inspectors verified the operability of an engineered safety features system by performing a walkdown of the accessible portions of Diesel The inspectors confirmed that the licensee's system

lineup procedures matched plant drawings and the as-built configuratio 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 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 indications for status agreemen .Within the areas inspected, no violations or deviations were identifie . Operational Safety Verification (71707)

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,' tours of the facility, interviews and discussions with licensee personnel, independent verification of safety system status and limiting conditions for operation, and reviewing facility records. Verifications and l

observation of control room staffing and shif t turnovers were adequate in operational area Observation of instrumentation and recorder traces control room annunciators, personnel performance, and review of control room i logs confirmed that appropriate actions to return the situations to normal was adequate.

Information Meeting With Local Officials (94600)

= Hugh C. Dance, Section Chief, Division of Reactor Projects, Region . II and the Sen.ior Resident Inspector met with the Fairfield County Administrator and the Director of' Emergency Preparedness on January 28, 1986. This meeting -was held to update t.hese officials on the NRC mission . and to introduce the recently assigned Senior Resident Inspector. In addition, an informal visit and review of the materials in the Public Document Room at the Fairfield County Library was conducte The material was well maintained and readily available for public use.
