The inspectors used the definitions and guidance contained in NEI (Nuclear Energy Institute) 99-02, Regulatory Assessment Performance Indicator Guideline, Revision 5, to assess the accuracy of PSEGs collection and reporting of PI data. The documents reviewed by the inspectors are listed in the Attachment.
Cornerstone: Initiating Events
- Unplanned Scrams per 7000 Critical Hours
- Unplanned Scrams with Complications
- Unplanned Power Changes per 7000 Critical Hours The inspectors reviewed the data reported for these PIs for the period January 1 through December 31, 2008. The records reviewed included PI data summary reports, licensee event reports, monthly operating reports, and operator narrative logs. The inspectors verified the accuracy of the number of critical hours reported, and interviewed the system engineers responsible for data collection and evaluation.
Cornerstone: Emergency Preparedness
- Drill and Exercise Performance
- ERO Drill Participation
- ANS Reliability For the PIs listed above, to verify the accuracy of the reported data, the inspectors reviewed the PI data, supporting documentation and the information PSEG reported, from the second quarter through the fourth quarter of 2008
b. Findings
No findings of significance were identified.
4OA2 Identification and Resolution of Problems
.1 Review of Items Entered into the Corrective Action Program:
As required by Inspection Procedure 71152, Identification and Resolution of Problems, and in order to help identify repetitive equipment failures or specific human performance issues for follow-up, the inspectors performed a daily screening of all items entered into PSEG's corrective action program. This was accomplished by reviewing the description of each new notification and attending daily management review committee meetings.
4OA3 Event Followup
.1 (Closed) LER 05000354/2009-001, Reactor Manual Scram Due to Turbine Runback
On January 17, 2009, operators initiated a manual reactor scram in response to a main turbine runback caused by a loss of main generator stator cooling. The loss of stator cooling occurred due to a turbine auxiliary cooling system isolation valve that failed shut.
The solenoid for the valve was determined to have a detached lead. This lead had been replaced approximately one week prior to the event. This condition was not caused by a performance deficiency associated with the maintenance activity.
The resident inspectors responded to the site and verified that plant systems responded as designed to the transient and operator response was consistent with plant procedures. The inspectors reviewed control board indications, plant logs, computer alarm data, and other post-transient records and data. The inspectors also reviewed PSEGs prompt investigation, apparent cause evaluation, and root cause evaluation for this event.
The inspectors reviewed LER 05000354/2009-001 and determined that the direct cause, the solenoid failure, was not within PSEG's ability to foresee and correct, and therefore would not meet the screening criteria for a finding. The inspectors identified no findings of significance and determined there was no violation of NRC requirements. This LER is closed.
4OA5 Other Activities
.1 Quarterly Resident Inspector Observations of Security Personnel and Activities
a. Inspection Scope
During the inspection period, the inspectors conducted observations of security force personnel and activities to ensure that the activities were consistent with PSEG security procedures and regulatory requirements relating to nuclear plant security. These observations took place during both normal and off-normal plant working hours. These quarterly resident inspector observations of security force personnel and activities did not constitute any additional inspection samples. Rather, they were considered an integral part of the inspectors normal plant status review and inspection activities.
b. Findings
No findings of significance were identified.
.2 TI 2515/173, Review of the Implementation of the Industry Ground Water Protection
Voluntary Initiative
a. Inspection Scope
On March 9-13, 2009, the inspectors assessed PSEGs ground water protection program to verify that PSEG implemented the voluntary industry Ground Water Protection Initiative (GPI). The GPI was unanimously approved by a formal vote of the Nuclear Energy Institute (NEI) member utility chief nuclear officers. This established the industrys commitment to implement the initiative. The GPI identifies the actions the industry deemed necessary for implementation of a timely and effective ground water protection program.
The inspectors verified that the following objectives for the GPI were contained in PSEG's program:
1.1 Site Hydrology and Geology 1.2 Site Risk Management 1.3 On-Site Ground Water Monitoring 1.4 Remediation Process 1.5 Record Keeping 2.1 Stakeholder Briefing 2.2 Voluntary Communication 2.3 Thirty-Day Reports 2.4 Annual Reporting 3.1 Perform a Self-Assessment 3.2 Review the Program Under the Auspices of NEI Unit 2 Emergency Sump The inspectors reviewed documentation and PSEG actions related to the identification of tritium in the Unit 2 emergency sump, located below the 54 elevation in the turbine building. The inspectors discussed with PSEG the testing and reviews conducted to determine the source of the tritium. PSEG's investigation determined that the source of the tritium was condensation from the turbine building administrative area heating ventilation and air conditioning (HVAC) unit, and that the tritium from the condensation came from the Technical Specification/Offsite Dose Calculation Manual authorized effluent releases from the plant vents being drawn into the HVAC intake. The inspectors confirmed that the information developed from PSEG's investigation, including various system testing and data collection, supported this conclusion.
The inspectors also reviewed PSEG's investigation efforts and actions taken to determine the cause of frequent makeup of water volume to the condensate storage tank. While investigation is still continuing, PSEG's efforts did provide basis to conclude that there were no leaks to ground water in associated underground piping, valving, or the tank.
b. Findings
No findings of significance were identified.
.3 Correction to NRC Cross-Cutting Aspect Coding of NRC Finding NCV
05000354/2009006-03, Failure to Follow Procedures Contributes to Emergency Diesel Generator Inoperability NRC Inspection Report 05000354/2009006 dated March 16, 2009, documented a Green finding associated with PSEGs failure to follow a surveillance test procedure. The finding had a cross-cutting aspect in the area of human performance and the aspect of work practices, procedural compliance, because PSEG personnel did not follow procedures. However, the finding documentation in Inspection Report 05000354/2009006 contained a typographical error. Specifically, in analysis section for the finding and the summary of findings section for the report the cross-cutting aspect code for this finding was incorrectly listed as H.2(b). The correct cross-cutting aspect code for this finding was H.4(b).
.4 TI 2515/175, Emergency Response Organization, Drill/Exercise Performance Indicator
Program Review The inspectors performed TI 2515/175, ensured the completeness of PSEGs completed 1 from the TI, and then forwarded the data to NRC, HQ.
4OA6 Meetings, Including Exit
The resident inspectors presented the inspection results to Mr. George Barnes and other members of PSEG staff on April 8, 2009. The inspectors verified that proprietary material reviewed by the inspectors during this period was properly controlled and the content of the report includes no proprietary information.
