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.

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.
