1R13 Maintenance Risk Assessments and Emergent Work Evaluation
a. Inspection Scope
The inspectors completed four maintenance risk assessment and emergent risk evaluation inspection samples. The inspectors reviewed the scheduling and control of the emergent work activities listed below to evaluate the effect on plant risk. The inspectors conducted interviews with operators, risk analysts, maintenance technicians, and engineers to assess their knowledge of the risk associated with the work, and to ensure that appropriate risk management actions were implemented. The actions taken were evaluated using the following Seabrook procedures: Maintenance Manual 4.14, "Troubleshooting," Revision 0 and Work Management Manual 10.1, "On-Line Maintenance," Revision 3.

1R15 Operability Evaluations (71111.15 - 5 Samples)
a. Inspection Scope
The inspectors completed five operability evaluation inspection samples. The inspectors reviewed operability evaluations and condition reports to verify that identified conditions did not adversely affect safety system operability or overall plant safety. The evaluations were reviewed using criteria specified in NRC Regulatory Issue Summary 2005-20, "Revision to Guidance formerly contained in NRC Generic Letter 91-18, Information to Licensees Regarding two NRC Inspection Manual Sections on Resolution of Degraded and Nonconforming Conditions and on Operability" and Inspection Manual Part 9900, "Operability Determinations and Functionality Assessments for Resolution of Degraded or Nonconforming Conditions Adverse to Quality or Safety." In addition, where a component was determined to be inoperable, the inspectors verified that TS limiting condition for operation implications were properly addressed.

OTHER ACTIVITIES
4OA1 Performance Indicator (PI) Verification (71151 - 3 Samples)
a. Inspection Scope
Cornerstone: Mitigating System
The inspectors reviewed NEXTera information from the second quarter of 2008 to the first quarter of 2009 for the Seabrook mitigating systems performance index (MSPI) PIs listed below:
- Cooling Water System MSPI
- Safety System Functional Failure The inspectors reviewed the consolidated data entry MSPI derivation reports for the unavailability and unreliability indexes (UAI and URI) for the monitored systems; the monitored component demands and demand failure data for the monitored systems; and the train and system unavailability data for the monitored systems. The inspectors verified the accuracy of the data by comparing it to corrective action program records, control room operators' logs, maintenance rule performance and scope reports, system performance/health reports, the equipment/operability issues database, the site operating history database, key performance indicator summary records, operating data reports and the MSPI basis document. To confirm the accuracy of the PI data reported during that period, PI definitions and guidance contained in NEI 99-02, "Regulatory Assessment Indicator Guideline," Revision 5, was used to verify the basis for reporting each data element.
Cornerstone: Barrier Integrity
- RCS Specific Activity The inspectors observed sample collection and reviewed the results of an RCS sample for iodine analysis performed on June 30, 2009, per procedure CS0910.01. The inspectors compared the analysis results of the sample performed by the chemistry department to the limits in T5 3.4.8, "Specific Activity," and previously reported RCS activity performance indicator data.
b. Findings
No findings of significance were identified.
4OA2 Identification and Resolution of Problems (71152 - 2 Samples)
.1 Review of Items Entered into the Corrective Action Program
a. Inspection Scope
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 items entered into the Seabrook corrective action program (CAP). This review was accomplished by accessing NEXTera's computerized database.
b. Findings
No findings of significance were identified.
.2 Semi-annual Review to Identify Trends
a. Inspection Scope
As required by Inspection Procedure 71152, "Problem Identification and Resolution," the inspectors performed a review of the Seabrook CAP and associated documents to identify trends that may indicate existence of safety significant issues. The inspectors' review was focused on repetitive equipment and corrective maintenance issues, but also considered the results of daily CAP item screening. The inspectors compared their results with the results contained in the Seabrook CAP Quarterly Trend Reports.
b. Assessment and Observations No findings of significance were identified. The inspectors did not identify any trends that NEXTera had not already identified.
.3 Annual Review of Operator Workarounds
a. Inspection Scope
The inspectors completed one problem identification and resolution annual inspection sample by completing a review of operator workarounds at Seabrook. The inspectors reviewed Seabrook
=s open operator workarounds and burdens to assess the cumulative impact of these issues on an operator
=s ability to implement emergency procedures or respond to plant transients. The inspectors verified that identified workarounds were properly tracked and that corrective maintenance for each issue was appropriately scheduled based on safety significance and the potential impact on plant operation.
The inspectors examined Seabrook procedure NAP-402, "Conduct of Operations,@ Attachment K, "Operator Workarounds and Burdens," to verify that the procedure provided the guidance necessary to adequately assess and address the cumulative impact of identified workarounds on the safe operation of the plant. The inspectors reviewed "turnover" information and toured the plant to verify that degraded conditions were appropriately identified and assessed as an operator workaround or burden.
b. Findings
No findings of significance were identified.
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 NEXTera security procedures and regulatory requirements related to nuclear plant security. These observations took place during both normal and off-normal plant working hours. These observations did not constitute an additional inspection sample. Rather, they were considered an integral part of the inspectors' normal plant status reviews and inspection activities.
b. Findings
No findings of significance were identified.
4OA6 Meetings, including Exit
Exit Meeting Summary
The inspectors presented the inspection results to Mr. Paul Freeman on July 1, 2009, following the conclusion of the period. NEXTera Energy acknowledged the findings presented and indicated that none of the information presented at the exit meeting was proprietary.
