Summarv of Plant Status At the beginning of this inspection period, Unit 1 was operating at 100 percent reactor power. On June 19, reactor power was reduced to 80 percent for increased safety margin during the repair of Steam Generator Feedwater Pump 13. The unit was returned to full power on June 22. On June 28, Unit 1 was removed from service for the purpose of testing the rod cluster control assemblies. At the end of this inspection period, the Unit 1 reactor was subcritical in Mode At the beginning of this inspection period, Unit 2 was operating at 13 percent reactor power. On May 18, the unit was removed from service to replace a flexible boot that had failed on Main Transformer 28. The unit was returned to power the same day and achieved 100 percent power on May 19. At the end of this inspection period, the Unit 2 reactor was operating at 100 percent steady-state powe .

Manual calculations properly verified the accuracy of the plant computer primary j calorimetric routine. Operators were maintaining reactor thermal power at or below '
licensed limits within instrument accuracie E1.2 Minimum Reactor Coolant System Boron Concentration (37551)
The inspectors reviewed Revision 5 to Procedure OPSP10-DM-0003. This revision authorized the use of a conservative minimum Xenon worth in determining .
shutdown margin limits during control rod drop time testing. The purpose of this method of determining shut down margin was to reduce the amount of boric acid added to the reactor coolant system during mid-cycle testing. Therefore, licensed operators saved time and water in returning the unit to powe The inspectors concluded that taking credit for the negative reactivity provided naturally by the postshutdown Xenon peak, was sound and provided sufficient conservatism to ensure that shutdown margin limits were met throughout the l testing evolution. In addition, independent calculations were performed to verify the accuracy of the engineers calculation E8 Miscellaneous Engineering issues (92903)
E (Closed) LER 50-498/94-019: Failure to fully meet the requirements of Technical Specifications for time response testing of the reactor containment fan cooler, and t the control room envelope heating, vcntilation and air conditioning systems, t
On November 9,1994, licensee engineers were reviewing the safety injection activation and response time test surveillance procedure as part of the surveillance -
procedure enhancement program and determined that the response time testing of ,
the reactor containment fan cooler, control room envelope and fuel handling building heating, ventilation and air conditioning systems was not complete. This condition was caused by inadequacies in the 18-month surveillance test procedure. A
.
determination was made that the spin-up times of the fans had not been considered I int he time response acceptance criteri L
! f
' The licensee entered Technical Specification 4.0.3 for both units, in order to !
complete the surveillance requirements. The spin-up times were obtained for the .
[ affected fans of both Units using motor current decay measurements. Those times l were applied to times to breaker closure and verified to be less than the Technical i Specification required values. Both units exited Technical Specification 4.0.3 on
November 10,1994.

The licensee's corrective action included:
- Spin-up times had been obtained for the affected fans of both Units using motor current decay measurements. Those times were added to times to breaker closure and verified to be less than the Technical Specification required values for overall requirement * The safety injection actuation and response time test surveillance procedure was revised to include spin-up time for reactor containment fan cooler and the control room enveloped heating, ventilation and air conditioning system * The licensee recognized deficiencies in the surveillance procedures and dealt with them under the Surveillance Procedure Enhancement Progra The inspector determined that these corrective actions fully met the requirements of the Technical Specifications. In addition, the NRC staff had been monitoring the licensee's progress with respect to surveillance procedure upgrades and have noted continual improvements with the station procedures. However, the failure to fully meet the Technical Specification surveillance requirements because of an- l l inadequate surveillance procedure is a violation. This licensee-identified and corrected viohtion is being treated as a noncited violation, consistent with Section Vll.B.1 of the NRC Enforcement Policy (498;499/97004-01).
E8.2 (Closed) LER 50-499/95-001: Pctential Slight Degradation of Decay Heat Removal Capacity Via Natural Circulatio ,
l On January 19,1995, licensee engineers had reviewed an industry experience notification concerning a degraded standby decay heat removal capability even They determined that there had been three instances when only one residual heat removal train was operable with the reactor coolant system vented to atmosphere and credit being taken for steam generators as backup decay heat removal source Although the licensee had met the Technical Specifications conditions, the ability to remove decay heat via the stream generators may have been slightly degraded during the period that the reactor coolant system'was open to the atmospher The cause of the event was a failure to fully evaluate the thermodynamic basis of the Technical Specifications. The specifications basis assumption was that the steam generators would be capable of removing decay heat by natural circulation whenever the reactor coolant system loops were full. This capability was challenged with the reactor coolant system vented to the atmosphere. An engineering evaluation completed on February 21,1995, concluded that the steam generators would have been capable of removing decay heat for at least 75 hours8.680556e-4 days <br />0.0208 hours <br />1.240079e-4 weeks <br />2.85375e-5 months <br /> before boiling would have occurred. That would have been sufficient time for
'
action to be taken to mitigate any adverse event.

. The licensee's corrective action included:
e Voluntary submission of Inis LER to inform the NRC of the problem
e Licensed operators were briefed concerning this issue and the thermodynamic basis to ensure that a similar event does not occu e Appropriate procedures were revised to ensure guidance provided to rely upon natural circulation would be adequate for plant condition The inspector determined that these corrective actions were sufficient to resolve the potential concern of a degraded decay heat removal capacity via natural circulatio No violation was identifie IV. Plant Support R1 Radiological Protection and Chemistry Controls R1.1 Tours of Radioloaical Controlled Areas Insoection Scope (71750)
The inspectors routinely toured the mechanical-auxiliary and fuel-handling buildings in Units 1 and 2. These tours included observation of work, verification of proper radiological work permits, sampling of locked doors, and observations of personnel entrance to and egress from the radiological controlled area Observations and Controls Radiological housekeeping in the areas toured was very good. Doors required to be locked in accordance with Technical Specification 6.12.2 and the licensee's radiological program were properly secured. No entrance / egress discrepancies were identified. Postings and labeling of radiological areas were perforrned in accordance with the licensee's procedures. These procedures met the requirements identified in 10 CFR Part 2 In addition, the inspectors reviewed the control room monitors for the plant stack, vents, and effluent releases, and determined that allindications were within the required specifications indicating no uncontrolled release During the Unit 1 shutdown on June 28, the inspectors noted an iodine activity level spike in the reactor coolant system. The system engineer stated that the spike had been anticipated based on the presence of small fuelleaks in the core and past operational history. The inspectors reviewed the acceptance criteria for iodine levels and verified that the magnitude of the spike had not exceeded any of the specification _ _ _ _ _ _ __ _ ._ _ _ . . _ . . _ _ _ . _ _ . _ . . _

R1.2 Scread of Contamination in the Unit 1 Mechanical-Auxiliary Buildina (71750) Event Descriotion On May 21, a reactor plant operator identified water backing up through the normal i -- floor drains located on the 41-foot elevation level of the mechanical-auxiliary j' building (MAB). Operations personnel were in the process of pumping down the sump area between the fuel handling building and the reactor containment buildin Valve 1-WL-0311 was found to be not fully opened, and the sump pump capacity
-
exceeded the capacity of the partially opened valve. As a result, the excess water l backed up through the MAB floor drains. The water being pumped from'the sump area was clean, ground seepage water, but the drain piping had been slightly i
contaminated causing the water backing up through the drains and onto the floor of
'
the MAB to also be slightly contaminate The condition was identified shortly after pumping had commenced. Engineers estimated that approximately 100-300 gallons of water had backed up into the
! drains and onto the floor area. Operators and the radiation protection technicians
! immediately took control of the area, limiting access and commenced an inspection j of the affected floor area including other areas and floors that may have been L affected. Operators quickly identified the problem of the partially opened valve and ~
l corrected the error. Radiation protection personnel were then able to clean and l decontaminate the affected areas. Condition Report CR 97-9009 was written to document and evaluate the even Observations and Findinas !
Upon hearing the announcement by control room operators of limiting access to the
identified areas of the MAB, the inspectors reported to the control room. The
! operators thoroughly explained the event and current clean up activities. The l inspectors reviewed the condition report and subsequent investigation reports l pertaining to the event. The inspector also interviewed several operators and radiation protection personnel in conjunction with the event and found the actions ;
taken to be responsive and appropriate for the event. The licensee's investigation into the problem of the partially opened valve identified that one of the multiple knuckles on a valve reach rod had broken providing the operator a response similar
! to that of a fully opened valve.
