SUBJECT:

ANNUAL ASSESSMENT LETTER - CLINTON POWER STATION (05000461/2008001)

Dear Mr. Pardee:

On February 13, 2008, the NRC staff completed its performance review of Clinton Power Station. Our technical staff reviewed performance indicators (PIs) for the most recent quarter and inspection results for the period from January 1 through December 31, 2007. The purpose of this letter is to inform you of our assessment of your safety performance during this period and our plans for future inspections at your facility.

This performance review and enclosed inspection plan do not include security information.

A separate letter designated and marked as "Official Use OnlySecurity Related Information" will include the Security Cornerstone review and resultant inspection plan.

Overall, Clinton Power Station operated in a manner that preserved public health and safety and fully met all cornerstone objectives. Plant performance for the most recent quarter was within the Licensee Response column of the NRCs Action Matrix, based on all inspection findings being classified as having very low safety significance (Green) and all PIs indicating performance at a level requiring no additional NRC oversight (Green). Therefore, we plan to conduct reactor oversight process (ROP) baseline inspections at your facility.

While plant performance for the most recent quarter is within the Licensee Response column of the Action Matrix, there was a safety significant inspection finding affecting the first three quarters of the assessment cycle. Specifically, Clinton Power Station was in the Regulatory Response Column of the NRCs Action Matrix for the first, second, and third quarters of CY 2007 based on one White finding in the Mitigating Systems Cornerstone for failure to adequately address vortexing in the reactor core isolation cooling (RCIC) storage tank and its effect on operability of the high pressure core spray (HPCS) and RCIC system. On June 6, 2007, we were notified by your staff of your readiness for the NRC to conduct a supplemental inspection to review the actions taken to address the White finding in the Mitigating Systems Cornerstone. We completed supplemental inspection procedure 95001 on September 7, 2007. Based on the results of this inspection, no findings of significance were identified. The enclosed inspection plan details the inspections, including baseline and other infrequently conducted inspections, less those related to security, scheduled through June 30, 2009. The inspection plan is provided to allow for the resolution of any scheduling conflicts and personnel availability issues well in advance of inspector arrival onsite. Routine resident inspections are not listed due to their ongoing and continuous nature. The inspections scheduled include:

triennial fire protection, engineering modifications/50.59, and biennial PI&R inspection. The inspections in the last nine months of the inspection plan are tentative and may be revised at the mid-cycle review.

In accordance with 10 CFR 2.390 of the NRCs Rules of Practice, a copy of this letter and its enclosure will be made available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRCs document system (ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

If circumstances arise which cause us to change this inspection plan, we will contact you to discuss the change as soon as possible. Please contact Mark Ring at 630-829-9703 with any questions you may have regarding this letter or the inspection plan.

Sincerely,

/RA/
