~ l 2 Plant Operations - (71707) General The inspection staff reviewed plant operations throughout the reporting period to verify conformance with regulatory requirements, Technical Specifications, and administrative controls. Control logs, shift supervisors' logs, shift relief records, LC0 status logs, night orders and standing orders, lifted wires and jumper logs, and clearance logs were routinely reviewe Discussions were conducted with plant operations, maintenance, chemistry, health physics, engineering support'and technical support personnel. Daily plant status meetings were routinely attende Activities within the control room were monitored during shifts and shift changes. Actions observed were conducted as required by the licensee's procedures. The complement of licensed personnel on each shift met or exceeded the minimum required by TSs. Direct observations were conducted of control room panels, instrumentation and recorder traces important to safety. Operating parameters were observed to verify they were within TS limits. The inspectors also reviewed DCs to determine whether the licensee was appropriately documenting problems and implementing corrective action Plant tours were taken during the reporting period on a routine basi They included, but were not limited to, the turbine building, the auxiliary building, electrical equipment rooms, cable spreading I rooms, NSCW towers, DG buildings, AFW buildings and the low voltage switchyar I During plant tours, housekeeping, security, equipment status and radiation control practices were observe The inspectors verified that the licensee's health physics policies / procedures were followe This included observation of HP practices and review of area surveys, radiation work permits,
!
i postings, and instrument calibration.
- The inspectors verified that the security organization was properl manned and security personnel were capable of performing their i assigned functions; persons and packages were checked prior to entry

resulting from the West Macintosh 500 XV line being out of nervic Power was returned to 90% on March 5, repairs to HDP A we"e completed and power was increased to 99%. On March 6, an ESF actuation occurred due to a voltage transient on the B train de system that i l
resulted isolation.in a control room ventilation and containment ventilation l The ESF actuation had no effect on power operation The unit operated at full power through the end of the report perio Unit 2 Summary
-
The unit began the pt:riod in Mode 3 following an automatic reactor trip on Overtemperature Delta T due to a circuit card failure. On February 24, criticality was achieved; the unit entered Mode 1 and the main generator was tied to the grid. The unit reached 100% power on February 25 and operated at full power until March 16. On March 16, the unit was shutdown for a planned outaga to install a main turbine EHC modification and to repair a leak on a SG #4 handhol The on unit 2 March achieved criticality and the generator was tied to the grid Unplanned Emergency Diesel Generator Start '
On March 21, during performance of procedure 14608-1, SSPS Slave Relay K601 Train A Test Safety Injection, an unplanned start of the 1A EOG occurred. Personnel performing the surveillance had incorrectly depressed the " Test SI" push button instead of the "SI OR U/V Test Output Switch 1A & IC" as called for in the procedure. The personnel involved had walked through the procedure prior to its performance and during the walk through had incorrectly identified which test push button was to be used. Three licensed personnel were present during the walkdown and none noticed that the panel pushbutton which they intended to use was not the one described in
, the procedure. This event was not considered to be reportable since the EDGs are not, by definition, ESF equipment. However, the licensee did write a DC, 1-91-079, which will require a formal' -
disposition as to reportability and corrective actions. The licensee stated that the specific procedure step will be reworded and that a
- broadness review of similar procedures will be performed to eliminate possible future misinterpretations. The resident inspectors consider this event to be an example of operator inattention to detail in following a plant procedur Unit 2 SG Secondary Side Access Handhole Leak Repair During recent Unit 2 operation, a leak developed around the seating surface'of a secondary side handhole on SG #4. The leak became apparent when the Containment Air Cooler Condensate Leak Detection system was alarming continuously. An analysis of the leak off determined the leak was not from the RCS. Walkdowns in containment determined that the leak was from a secondary side handhole close to

the tube sheet on the #4 steam generato Calculations on the magnitude of the leak ranged up to 4 gp l The licensee developed a repair scheme which called for shutting down the unit to Mode 3 (Hot Standby) and pressure injection of a sealant compound into the handhole cover plate. This repair scheme was intended to seal the void between the handhole cover and the SG shel Injection of the sealant compound involved drilling holes !
into the handhole cover plate. The licensee's safety evaluation of the leak repair technique involved the assessment of two issues: an evaluation of the structural aspects of the SG shell to determine that SG integrity was maintained; and the resultant effect on secondary side chemistry following introduction of the sealant compoun The inspectors reviewed the licensee's temporary modification request and 10 CFR 50.59 safety evaluation and were satisfied the licensee was taking a safe and conservative approac ,
'
Over the weekend of March 16, Unit 2 was shutdown to Mode 3 to perform the leak repair. The first attempt to stop the leak faile Following this attempt, the licensee discovered that the sealant used in the effort was inadequate for the temperature and pressure involved. Apparently, at normal operating temperature and pressure, the sealant turned to powder. The licensee in preparing the Temporary Modification Request failed to adequately consider the i i
effects of temperature. A second attempt at injecting sealant, using a metal clamp around the outside diameter of the flange and a different sealant, also failed to stop the leak. On March 20, Unit 2 ,
was taken to Mode 5 (Cold Shutdown). The #4 steam generator was drained and the leaking flange was removed for inspection and repai At the end of the inspection period the repairs had been completed and the unit was returning to powe f. Technical Specification Clarifications During this inspection report period, the inspectors noted three occasions where the licensee found it necessary to clarify or evaluate TS for continued conduct of operations. These three evaluations were all associated with the leak on the Unit 2 #4 steam generato In all three cases, the inspectors assessed the licensee's clarifications as safe and conservative. The inspectors paid particular attention to these interpretations because they all involvedweighingsafetyandeconomicfactors. The conservatism of
-
the licensee s interpretations have been questioned in the pas The first clarification involved the Containment Air Cooler Condensate Leak Detection system being in constant alarm (TS 3.4.6.1). The question was whether the constant alarm rendered this portion of the RCS leak detection system inoperable. The licensee's conclusion was that the alarm function is not required for the system

to perform its functio The system was operable as long as it was capable of being used for leakage detection. The licensee initiated a surveillance to calculate leak rate from air cooler condensate once per shif l The second decision involved a judgement on whether to go to Mode 4 I (Hot Shutdown) or Mode 5 (Cold Shutdowa) for removal and/or repair of the SG handhole. In Mode 4, the Containment Integrity TS was still applicable. With the potential removal of the handhole cover, the question arose whet 5er Containment Integrity would be violated if the plant was still in Mode 4. After considering this and other factors, l the licensee decided to go to Mode l The third clarification, applicable in Mode 5 only, involved a footnote in TS 3.4.1.4.1 which requires a RCP not be started unless secondary water temperature of each SG is less than 50 degrees F above each RCS cold leg temperature. The licensee wanted to start a i RCP with no RCPs running (in Mode 5) after securing the only running l RCP upon receiving a high vibration alarm (which later proved false). '
The basis for this TS is to prevent RCS pressure transients through energy addition from the secondary side. With SG #4 drained for the handhole repair a question arose as to applicability of'the TS to the empty SG. The licensee performed a thermodynamic analysis of air and l water and concluded it was acceptable to start a RCP with a SG draine g. ESF Actuations - Containment Ventilation Isolation And Control Room Isolation
l On March 6, personnel were troubleshooting an electricai ground in the Unit 1 125 vde switchgear. As a part of this process, the IB -
battery output breaker, 18D1-01, was opened creating a disconnect between the battery charge:rs and the batteries. When the battery chargers began making varnble pitched noises and the indicator light on the bus began to fluctuate in intensity the equipment operator I reclosed the breaker. In the control room a large number of annunciators were recie.ved including indications that a containment i ventilation isolation and control room isolation had occurred. All valves and dampers actuated as designe l The licensee's investigation determined that when circuit breaker 1BD1-01 was opened one of the two battery chargers (1BDICA)
experienced voltage fluctuations from 90 to 140 volts. A protection circuit in inverter 18D1112 automatically shutdown inverter operation when voltage from the chargers went below 105 volt When the inverter tripped, power was lost to various radiation monitors and other equipment that had annunciated in the control room. This caused the radiation monitors to send ESF actuation signals upon loss

! On March 19, the inspectors completed a system walkdown cf both trains of j the Unit 1 Containment Spray Sy: tem. The purpose of the walkdown was to
- determire whether the system lineup procedure, Containment Spray System
- Alignment, 11115-1, Rev. 5, agreed with the plant piping and
- instrumentation diagram, 1X4DB131, Rev. 22 and to identify equipmer.t
! conditions and items that might degrade plant performance.

Material condition of those areas inspected was good and nothing was ;
i observed which might affect system operability. However, several !
i discrepancies were noted regarding labeling of components. Specifically, l l two valves were missing plastic identification tags, the wording on seven j vaive identification tags did not exactly match the valve description in
- the system alignment procedure, and all twelve electrical breaker ID tags
, differed from the alignment procedure written description. These labeling j discrepancies were discussed with the licensee and corrective action will i be take The inspectors had no other concerns regarding this Containment j Spray System walkdown.

14980-2 Diesel Generator Operability Test 28911-2 Seven Day Battery Inspection And Maintenance Main Feedwater Regulating Valves And Bypass Valves Testing-During the licensee's review of Generic Letter 89-19, " Safety Implication of Control Systems in LWR Nuclear Power Plants", it was identified that the MFRVs and BFRVs, according to Westinghouse, are credited in tho safety analysis as a backup to the Feedwater Isolation Valves. Termination of main feedwater flow to a faulted steam generator is assumed in the steam line break and feed line break analyses in order to-limit the RCS cooldown and mass release from the break. As a result, the licensee added the MFRVs and BFRVs to the active valve list in the FSAR and included them in the Inservice Testing Program. When the Unit 1 active list IST program, and TS were originally developed the MFRVs and BFRVs were deliberately excluded because it was though'E thsi they were not required by the safety analyse To date, the Unit 1 BFRVs and the Unit 2 MFRVs and BFRVs have been tested with satisfactory results. The only remaining valves are the Unit 1 MFRVs which will not be tested within the time requirements now established in the testing program (MFRVs can only be tested with the plant shutdown).
Due-to the inability to stroxe test the MFRVs at power, the resident inspectors requested that the licensee justify the capability of the MFRVs to close within the specified time until the plant is in a mode in which the valves can be tested. The licensee, using completed ESF Response Time Summation procedures and I&C loop calibration

i procedures, obtained data which included times for the sensors, SSPS processing and closure times for the MFRVs. The response times for l each of the MFRVs was calculated to verify that they could meet the i' feedwater isolation response time requirements and the inservice testing requirements. All the calculations were within the specified time requirement ,

Reactor power was reduced to 90% of rated thermal power and was maintained at that power until previously scheduled maintenance on
the heater drain pump was completed. The manual actuation pin for the HDT high level dump valve was disengaged and the valve was i returned to automatic operation. The pins were modified so that they
' are now restrained in the automatic position. Licensed operators were trained during a subsequent requalification class on the i
conditions that led up to and caused the over power event.
