SUBJECT:

ANNUAL ASSESSMENT LETTER - BRAIDWOOD STATION, UNITS 1 AND 2, (05000456/2010001; 05000457/2010001)

Dear Mr. Pardee:

On February 10, 2010, the NRC staff completed its performance review of Braidwood Station, Units 1 and 2. Our technical staff reviewed performance indicators (PIs) for the most recent quarter and inspection results for the period from January 1 through December 31, 2009. 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 Only - Security Information" will include the Security Cornerstone review and resultant inspection plan.

Overall, Braidwood Station operated in a manner that preserved public health and safety and fully met all cornerstone objectives.

Plant performance for the most recent quarter at Braidwood Station Unit 1 was within the Regulatory Response Cornerstone column of the NRC's Action Matrix, based on one inspection finding being classified as having low-to-moderate safety significance (White) and all PIs indicating performance at a level requiring no additional NRC oversight (Green). The White finding involved the failure of the containment sump suction isolation valve to fully open.

When you notify us of your readiness, we will conduct a supplemental inspection for Braidwood Unit 1 using Inspection Procedure 95001, "Inspection for One or Two White Inputs in a Strategic Performance Area." In addition, we plan to conduct reactor oversight program (ROP) baseline inspections at Braidwood Unit 1.

Plant performance for the most recent quarter, as well as the first three quarters of the assessment periods at Braidwood Station Unit 2, was within the Licensee Response column of the NRC's 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 program (ROP)

baseline inspections at Braidwood Station Unit 2. The NRC also plans to conduct several special and infrequently performed inspection procedures (IPs), which include inspections related to the pre-operational testing and operation of the Independent Spent Fuel Storage Installation.

In the mid-cycle performance review letter dated September 1, 2009, [ML092440402], we advised you of a substantive cross-cutting issue in the area of human performance. The substantive cross-cutting issue was the result of several findings that involved deficiencies in human performance throughout the station. In response to the identified cross-cutting issues, you had provided us your Human Performance Improvement Plan and specific actions that you planned to take to correct the cross-cutting issue performance deficiencies.

Nevertheless, the staff has continued to have concerns with your human performance. During this assessment period, you have had three of these findings in the human performance area that shared the common cross-cutting aspect of failure to make conservative assumptions and demonstrating the proposed action is safe (H.1(b)). These findings were from more than one cornerstone (Mitigating Systems and Initiating Ev ents). Moreover, your Human Performance Improvement Plan actions have not yet proven effective in substantially mitigating the cross-cutting theme even though a reasonable duration of time has passed. Therefore, this substantive cross-cutting issue remains open until your corrective actions have resulted in a positive sustainable improvement in the area and the number of findings in the theme is reduced or maintained. Please provide a status update of the progress that was made to improve the human performance during the annual end-of-cycle public meeting to be scheduled at a later date. We will also access the human performance related issues as a Problem Identification and Resolution follow-up inspection item in accordance with IP 71152,

"Identification and Resolution of Problems," Section 03.02, "Selected Issue Follow-up Inspection."

The enclosed inspection plan details the inspections, less those related to physical protection, scheduled through June 30, 2011. Please note that we plan on conducting two infrequently performed IPs: IP 60854.1, "Preoperational Testing of an Independent Spent Fuel Storage Facility Installation at Operating Plants," and IP 60855.1, "Operation of an Independent Spent Fuel Storage Installation at Operating Plants," this year at your Braidwood Station. 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 in the last 9 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 NRC

=s A 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 NRC's document system (ADAMS). ADAMS is 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 Richard A. Skokowski at 630-829-9620 with any questions you may have regarding this letter or the inspection plan.

Sincerely,

/RA/

Steven West, Director Division of Reactor Projects
