NRC Strategic Goals z Safety: Ensure adequate protection of public health and safety and the environment z Security: Ensure adequate protection in the secure use and management of radioactive materials

Reactor Oversight Process Strategic Performance Areas Safety Cornerstones Baseline Inspection Performance Indicator Results Results Significance Significance Threshold Threshold Action Matrix Regulatory Response

Examples of Baseline Inspections z Equipment Alignment ~80 hrs/yr z Triennial Fire Protection ~200 hrs every 3 yrs z Operator Response ~125 hrs/yr z Emergency Preparedness ~80 hrs/yr z Rad Release Controls ~110 hrs every 2 yrs z Worker Radiation Protection ~90 hrs/yr z Corrective Action Program ~250 hrs every 2 yrs z Corrective Action Case Reviews ~60 hrs/yr

Significance Threshold Performance Indicators Green: Only Baseline Inspection White: May increase NRC oversight Yellow: Requires more NRC oversight Red: Requires more NRC oversight Inspection Findings Green: Very Low safety issue White: Low to moderate safety issue Yellow: Substantial safety issue Red: High safety issue

Action Matrix Concept Licensee Regulatory Degraded Multiple/Rep. Unacceptable Response Response Cornerstone Degraded Performance Cornerstone Increasing Safety Significance Increasing NRC Inspection Efforts Increasing NRC/Licensee Management Involvement Increasing Regulatory Actions

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-cutting issue in the area of Problem Identification & Resolution (PI&R)

Cross-Cutting Aspect: appropriate and timely corrective actions Biennial PI&R inspection rescheduled for Oct. 2008 (instead of 2009)

PI&R program effectiveness will be a focal point 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
