Unit 1 Assessment Results (contd) 2nd and 3rd quarters Unit 1 performance in the Licensee Response column 4th Quarter: Unit 1 performance within Degraded Cornerstone
- Unit 1 exceeds Yellow threshold for Initiating Events
- Based on number of unplanned scrams per 7000 Critical Hours
Substantive Cross-Cutting Issue NRC staff identified a cross NRC staff identified a cross--cutting issue in the area cutting issue in the area of Problem Identification & Resolution (PI&R) of Problem Identification & Resolution (PI&R)
Cross Cross--Cutting Aspect: appropriate and timely Cutting Aspect: appropriate and timely corrective actions corrective actions Biennial PI&R inspection rescheduled for Oct. 2008 Biennial PI&R inspection rescheduled for Oct. 2008 (instead of 2009)

PI&R program effectiveness will be a focal point PI&R program effectiveness will be a focal point during routine resident baseline inspections during routine resident baseline inspections
2007 Assessment Results-U2 & U3 (Jan 1 - Dec 31, 2007)
- U2 and U3 performance was within the Licensee Response Column of the Action Matrix for all four quarters.
- All Reactor Oversight Process inspection findings were classified as very low safety significance (Green).
- All performance indicators were Green.
Browns Ferry Nuclear Plant Annual Assessment Summary January 1 - December 31, 2007 TVA operated Browns Ferry in a manner that preserved public health and safety Unit 1 exceeded the Yellow threshold for the degraded cornerstone, Initiating Events, under the Unplanned Scrams per 7000 Critical Hours PI All cornerstone objectives were met for Units 2, 3 NRC plans baseline inspections at Browns Ferry Units 1,2,3 for the remainder of CY 2008 and a supplemental inspection for Unit 1 Continued Unit 1 Augmented Inspections
