The inspectors selected the following NCR for detailed review and discussion with the licensee.
- NCR 138396 Increased Wear Products in Service Water Pump (SWP-1B) Oil Sample The inspectors checked that the problem had been completely and accurately identified in the licensees corrective action program. Other attributes checked included disposition of operability, resolution of the problem including cause determination and corrective actions, and extent of condition. A number of related nuclear condition reports were reviewed by the inspectors to check for common cause or generic implication:
d. Findings and Observations
No findings of significance were identified.
Semi-Annual Trend Review
e. Inspection Scope
As required by Inspection Procedure 71152, "Identification and Resolution of Problems,"
the inspectors performed a review of the licensees corrective action program (CAP) and associated documents to identify trends that could indicate the existence of a more significant safety issue. The inspectors review was focused on repetitive equipment issues, but also considered the results of daily inspector CAP item screening discussed in section 4OA2.1 above, plant status reviews, plant tours, and licensee trending efforts.
The inspectors review nominally considered the six month period of July 2004 through December 2004, although some examples may have expanded beyond those dates when the scope of the trend warranted. The review also included issues documented outside the normal CAP in equipment problem lists such as the Equipment Performance Priority List dated November 30, 2004; the July 30, 2004 System Health Reports for the Turbine Generator, Reactor Coolant, and Main Steam, and Nuclear Services Closed Cycle Cooling systems, various nuclear assessment section reports, material condition reports (including boric acid corrosion program walkdowns) of the reactor building, and various maintenance rule assessments. The inspectors reviewed turbine vibration monitoring results for emergency feedwater pump EFP-2, maintained by the emergency feedwater system engineer, and main turbine equipment status report, 3rd Qtr 04 Equipment Walkdown Summary Report, Turbine Generator System, maintained by the main turbine system engineer. The inspectors compared and contrasted their results with the results contained in the licensees October 2004 Key Performance Indicator report. Corrective actions associated with a sample of the issues identified in the licensees trend report were reviewed for adequacy.
f. Assessment and Observations No findings of significance were identified. The inspectors in reviewing licensee performance over the last six months, noted two trends, discussed below.
First, a negative trend in fire prevention and mitigation preparedness was noted. The inspectors found on July 18, a fire extinguisher that had been missed in the licensees monthly fire extinguisher surveillance. Missed fire extinguishers during the monthly surveillance had been an area of concern in the NRC Problem Identification and Resolution inspection documented in IR 04-07. When the added example of a missed extinguisher was raised with the licensee, a CAP item was initiated and second independent checks were initiated for the remaining months of the year. (When checked, the fire extinguisher passed its surveillance check.) During fire protection walkdowns on October 14, the inspectors noted an amount of flammable debris (boxes, rolls of paper) had accumulated in the control complex locker area. Although the debris was within the licensees fire loading analysis, its storage in the control complex was unnecessary and after being identified to the licensee, it was removed. The inspectors documented a number of findings in the fire protection area in Inspection Report 04-05.
Also, the licensee had found that on October 1, 2004, a fire alarm had been disabled, but not tracked in the switch out-of-position log and this was documented in the CAP (NCR 138962). The inspectors discussed the basis for the conclusion that a trend existed with the licensee. When the inspectors raised a general concern of lowering of standards in the area of fire protection to the licensee, the licensee refocused attention on fire protection problems, the operations department established ownership of fire programs and made plant employees aware that fire prevention and mitigation were important aspects in minimizing risk. The licensee also initiated a review of adequacy of fire protection corrective actions (NCR 147824).
The second trend was identified when the inspectors found during system walkdowns a number of small boric acid leaks in the makeup, decay heat removal, and building spray systems. When identified to the licensee and consistent with their boric acid control program, work orders were written to remove the boric acid and engineering assessed the source to determine if any leakage was active. No active leaks were found by the inspectors. An active boric acid leak on the B decay heat pump was previously identified by the inspectors and documented in Inspection Report 04-05. The licensee had emphasized their program to identify any areas of suspected boric acid leakage for evaluation and repair and leaks were being repaired as identified.
4OA3 Event Followup
(Closed) LER 05000302/2004-001: Reactor Trip Caused by Failed Circuit Board in the Main Feedwater Integrated Control System
a. Inspection Scope
The event report summarized an event that occurred on March 24, 2004, caused by a failed component in the integrated control system that initiated a feedwater transient resulting in a reactor trip. The inspectors reviewed the licensee event report and the licensees review of the trip documented in their Administrative Instruction AI-704, Reactor Trip Review and Analysis Report. The inspectors also discussed aspects of the event with plant personnel. The inspectors checked the accuracy and completeness of the LER and the appropriateness of the licensees review and corrective actions. No performance deficiencies or violations of NRC requirements were identified.
b. Findings
No findings of significance were identified. The LER is closed.
4OA5 Other Activities
Institute of Nuclear Power Operations (INPO) Assessment Report Review
a. Inspection Scope
The inspectors reviewed the final report of the INPO assessment of site activities conducted in May 2004. The inspectors reviewed the report to ensure that issues identified were consistent with the NRC perspectives of licensee performance and if any significant safety issues were identified that needed further NRC followup.
b. Findings
No findings of significance were identified
4OA6 Meetings, Including Exit
Exit Meeting Summary
The resident inspectors presented the inspection results to Mr. Young and other members of licensee management at the conclusion of the inspection on January 4, 2005. The inspectors asked the licensee whether any of the material examined during the inspection should be considered proprietary. The licensee did not identify any proprietary information.
