operator workarounds at an appropriate threshold, entered the issues into the CAP, and
planned or implemented appropriate corrective actions.  The inspectors reviewed the
actions taken to verify that the licensee had adequately addressed the following
attributes:
*
Complete, accurate, and timely identification of the problem
*
Evaluation and disposition of operability and reportability issues
*
Consideration of previous failures, extent of condition, generic or common cause
implications
*
Prioritization and resolution of the issue commensurate with the safety
significance
*
Identification of the root cause and contributing causes of the problem
*
Identification and implementation of corrective actions commensurate with the
safety significance of the issue
The inspectors reviewed the associated corrective action for AR 250203, Unit 2 high
pressure coolant injection pump seal failure that occurred on October 10, 2007.

Semi-Annual Trend Review
    a.
Inspection Scope
The inspectors performed a review of the licensees CAP and associated documents to
identify trends that could indicate the existence of a more significant safety issue.  The
review was focused on repetitive equipment issues but also considered the results of
frequent inspector CAP item screening (discussed above), licensee trending efforts, and
licensee human performance results.  The review considered the period of July through
December 2007.  The review further included issues documented outside the normal
CAP in major equipment lists, repetitive and/or rework maintenance lists, operational
focus list, control room deficiency list, outstanding work order list, quality assurance
audit/surveillance reports, key performance indicators, and self-assessment reports.
The inspectors compared and contrasted their results with the results contained in
multiple root cause evaluations the licensee has performed over the last 2 quarters.
Corrective actions associated with a sample of the issues identified in the licensees
trend reports were reviewed for adequacy.  The inspectors also evaluated the reports
against the requirements of the licensees CAP as specified in Nuclear Generation
Group Standard Procedure CAP-NGGC-0200, Corrective Action Program, and 10 CFR
50, Appendix B. 
    b.
Assessment and Observations
No findings of significance were identified.  The inspectors noted a trend in the control
and retrieval of foreign material in systems and the adverse effects this has had on
system performance; this was exemplified by the following identified issues:
1) Foreign material found in the 1B Residual Heat Removal (RHR) Room cooler
(AR243465); 2) Metallic foreign material found in the 1B RHR Heat Exchanger
(AR246790); 3) 1D RHRSW Booster pump failed to start was bound by valve pin (AR
243867); 4) Unit 2 HPCI main pump inboard seal failure due to blockage of seal cooling
line (AR250203).  The inspectors have determined that the licensee has addressed all
immediate operability concerns, and is currently developing long-term improvements.
4OA6 Meetings, Including Exit
Exit Meeting Summary
On January 24, 2008, the resident inspectors presented the inspection results to
Mr. Waldrep and other members of his staff.  The inspectors confirmed that proprietary
information was not provided or examined during the inspection.

Temporary Plant Modifications

a.

Inspection Scope

The inspectors reviewed Operating Manual 0PLP-22, Temporary Changes, to assess

the implementation of Engineering Change (EC) 67830, Reactor Core Isolation Cooling

System Low Suction Pressure Trip Delay which was implemented on October 21, 2007.

The inspectors reviewed the EC to verify that the modification did not affect the

functional capability of the EDG, that the modification was properly installed, and

appropriate post-installation testing was performed.

b.

Findings

No findings of significance were identified.

Enclosure

High Pressure Coolant Injection System

Reactor Core Isolation Cooling System

A sample of plant records and data was reviewed and compared to the reported data to

verify the accuracy of the PIs. The licensees corrective action program records were

also reviewed to determine if any problems with the collection of PI data had occurred.

Documents reviewed are listed in the Attachment.

b.

Findings

No findings of significance were identified.

4OA2 Identification and Resolution of Problems

.1

Routine Review of ARs

To aid in the identification of repetitive equipment failures or specific human

performance issues for followup, the inspectors performed frequent screenings of items

entered into the licensees CAP. The review was accomplished by reviewing daily ARs.

.2

Annual Sample Review

a.

Inspection Scope

The inspectors performed an in-depth annual sample review of plant operator

workarounds as documented in licensees operator workaround program and corrective

action documents. This review was performed to verify that the licensee identified

operator workarounds at an appropriate threshold, entered the issues into the CAP, and

planned or implemented appropriate corrective actions. The inspectors reviewed the

actions taken to verify that the licensee had adequately addressed the following

attributes:

Complete, accurate, and timely identification of the problem

Evaluation and disposition of operability and reportability issues

Consideration of previous failures, extent of condition, generic or common cause

implications

Prioritization and resolution of the issue commensurate with the safety

significance

Identification of the root cause and contributing causes of the problem

Identification and implementation of corrective actions commensurate with the

safety significance of the issue

The inspectors reviewed the associated corrective action for AR 250203250203 Unit 2 high

pressure coolant injection pump seal failure that occurred on October 10, 2007.

Findings and Observations

No findings of significance were identified.

.3

Semi-Annual Trend Review

a.

Inspection Scope

The inspectors performed a review of the licensees CAP and associated documents to

identify trends that could indicate the existence of a more significant safety issue. The

review was focused on repetitive equipment issues but also considered the results of

frequent inspector CAP item screening (discussed above), licensee trending efforts, and

licensee human performance results. The review considered the period of July through

December 2007. The review further included issues documented outside the normal

CAP in major equipment lists, repetitive and/or rework maintenance lists, operational

focus list, control room deficiency list, outstanding work order list, quality assurance

audit/surveillance reports, key performance indicators, and self-assessment reports.

The inspectors compared and contrasted their results with the results contained in

multiple root cause evaluations the licensee has performed over the last 2 quarters.

Corrective actions associated with a sample of the issues identified in the licensees

trend reports were reviewed for adequacy. The inspectors also evaluated the reports

against the requirements of the licensees CAP as specified in Nuclear Generation

Group Standard Procedure CAP-NGGC-0200, Corrective Action Program, and 10 CFR 50, Appendix B.

b.

Assessment and Observations

No findings of significance were identified. The inspectors noted a trend in the control

and retrieval of foreign material in systems and the adverse effects this has had on

system performance; this was exemplified by the following identified issues:

1) Foreign material found in the 1B Residual Heat Removal (RHR) Room cooler

(AR243465243465; 2) Metallic foreign material found in the 1B RHR Heat Exchanger

(AR246790246790; 3) 1D RHRSW Booster pump failed to start was bound by valve pin (AR

243867); 4) Unit 2 HPCI main pump inboard seal failure due to blockage of seal cooling

line (AR250203250203. The inspectors have determined that the licensee has addressed all

immediate operability concerns, and is currently developing long-term improvements.
