REPORT DETAILS

Summary of Plant Status

Crystal River Unit 3 began the inspection period at 100 percent power. On July 3, theoperators reduced power to approximately 84 percent due to an unexpected trip of one of four non-safety related circulating water pumps (CWP-1D). The unit was returned to full power operation on July 5. The unit operated at essentially full power until August 19 when the unit was shutdown to mode 5 (cold shutdown) to repair a main feedwater leak. The unit was restarted on August 23 and was returned to full power on August 24. The unit remained at essentially full power until September 30 when power was manually reduced to approximately 57 percent when one of the two condensate pumps lost control power due to an electrical fault.

Power was raised to approximately 68 percent later that day.1.

12Enclosure4OA2Problem Identification and Resolution.1Daily Screening of Items Entered Into the Corrective Action Program

a. Inspection Scope

As required by inspection procedure 71152, "Identification and Resolution ofProblems," and in order to help identify repetitive equipment failures or specific human performance issues for follow-up, the inspectors performed a daily screening of items entered into the licensee's CAP. This review was accomplished by attending daily plant status meetings, interviewing plant operators and applicable system engineers, and accessing the licensee's computerized database.

b. Findings

No findings of significance were identified.

.2 Annual Sample Review

a. Inspection Scope

The inspectors selected NCRs 196164 and 188885 for a detailed review. In additionthe inspectors reviewed the operator workaround program to verify the licensee is identifying workarounds at an appropriate threshold and is entering them in the corrective action program. The inspectors performed an evaluation of the potential cumulative effect of all outstanding operator workarounds. The NCRs were initiated to evaluate 1) on May 31, 2006, as-found voltage for EGDG-1B was below the acceptance criteria during SP-354B, monthly functional test of the emergency diesel generator EGDG-1B, and 2) corroded piping and supports on piping to RWP-3A. The inspectors checked that the issue had been completely and accurately identified in the licensee's CAP, and that safety concerns were properly classified and prioritized for resolution, apparent cause determinations were sufficiently thorough, and appropriate corrective actions were implemented in a manner consistent with safety and compliance with plant technical specifications and 10 CFR 50. The inspectors also evaluated the NCR using the requirements of the licensee's CAP as delineated in corrective action procedure CAP-NGGC-200, Corrective Action Program.

b. Findings and Observations

No findings of significance were identified. NCR 196164 documented finding EGDG-1B voltage outside of the acceptance criteriaduring a routine monthly (May 2006) surveillance. The licensee initially determined that the voltage was low due to incorrect setting of the local manual Rheostat. A second NCR (196165) addressed the fact that the operator failed to inform the control room supervisor (CRS) of the out of specification as-found values. The second NCR specified an enhancement to discuss with the operator involved, the need to inform the 13EnclosureCRS when unexpected conditions arise. In August, the as-found voltage for EGDG-1Bwas again found outside the acceptance criteria during the monthly surveillance (NCR 204386). The Rheostat was subsequently replaced. The inspectors determined that since April 2006, there were three additional instances when the voltages for EGDG-1B were found outside of the acceptance criteria. Each time the voltages were adjusted by the surveillance procedure however, NCRs were not written. After discussions with the licensee, NCR 206491 was written to address the failure to write NCRs. The licensee re-evaluated the emergency diesel generator loading calculation and determined the as-found low voltages did not affect EGDG-1B operability. The inspectors noted that NCR 196164 was inappropriately classified as priority 5 for trending only. A more thorough review would have determined that the as-found voltages were outside the acceptable range during the previous two monthly surveillances and was due to equipment degradation. The inspectors identified that the licensee had not thoroughly documented the seismicevaluation of corroded pipe supports that had been found on decay heat closed cycle cooling water (DC) piping to RWP-3A motor cooler. Two NCRs describing similar issues relating to corrosion on DC pipe and its supports had been written. NCR 188885 was written to evaluate corrosion identified on the piping. NCR 188942 was written to evaluate corroded pipe supports on the same piping. NCR 188942 referenced an evaluation documented in NCR 188885. The evaluation described the technical basis for concluding that the pipe had adequate wall thickness to maintain a leak free pressure boundary. However, the inspectors noted that the evaluation did not address the corrosion on the pipe supports that had been identified in NCR 188942.

After reviewing this issue with the licensee, engineering determined that the evaluation had been completed but that the documentation had not been added to the NCR as had been planned. NCR 188885 was reopened and updated to address the corroded pipe supports. The inspectors did not identify any operability or regulatory issues. The inspectors determined that, in general, the licensee was identifying workarounds atan appropriate threshold and is entering them in the corrective action program for resolution. The inspectors did find one degraded component, feedwater valve FWV-217 (non-safety auxiliary feedwater discharge valve to B steam generator) that required manual actions for approximately one week that was not screened as an operator workaround. Since this valve was used in emergency operating procedures, the manual actions would have classified it as a Category 1 operator workaround under the licensees program. All compensatory actions necessary for a Category 1 workaround were in place, however it was not screened as a workaround. The licensee initiated NCR 206113 to address this issue. 40A3Followup of Events and Notices of Enforcement Discretion
