NRC Performance Goals PRIMARY GOALS Ensure protection of the public health and safety and the environment Ensure the secure use and management of radioactive materials OTHER GOALS

• Ensure openness in NRC regulatory process

• Ensure that NRC actions are effective, efficient, realistic, and timely

• Ensure excellence in NRC management to carry out the NRCs strategic objective

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

Performance Thresholds Safety Significance Green: Very low safety issue White: Low-to-moderate safety issue Yellow: Substantial safety issue Red: High safety issue NRC Inspection Efforts Green: Only Baseline Inspections White: May increase NRC oversight Yellow: Increased NRC oversight Red: Increased NRC oversight and other NRC actions

Watts Bar CY 2005 Assessment Results

• Watts Bar performance at the end of the assessment year was within the Licensee Response Column of the NRCs Action Matrix

• All finalized inspection findings for CY 2005 were classified as very low safety significance (Green)

• All performance indicators (PI) for CY 2005 were Green

CY 2005 Assessment Results Contd

• Watts Bar performance for the first three quarters was in the Regulatory Response Column of the NRCs Action Matrix due a White Finding identified in the fourth quarter of CY 2004

• White Finding was in the Mitigating Systems Cornerstone and involved silting in the raw water cooling system

CY 2005 Assessment Results Contd

• Supplemental Inspection conducted in July 2005 determined corrective actions were thorough and appropriate

• November 22, 2005 Regulatory Performance Meeting reviewed licensee actions

• White Finding closed after four quarters

CY 2005 Assessment Results Contd

• Substantive cross-cutting human performance issue identified during mid-cycle assessment in the Mitigating Systems and Barrier Integrity Cornerstones

• Common performance deficiency of failure to implement procedures

CY 2005 Assessment Results Contd

• Licensee presented corrective actions to Region II management during two meetings

• Routine daily PI&R reviews and planned annual samples to focus on human performance issues

CY 2005 Assessment Results Contd

• Inspection activities and reviews determined that the licensee adequately addressed the substantive cross-cutting issue as demonstrated by performance trends, low number of subsequent findings and ongoing corrective actions such as the TVA Human Performance Improvement Plan

• The substantive cross-cutting issue was closed by NRC letter dated March 2, 2006

Watts Bar Assessment Summary TVA operated Watts Bar in a manner that preserved public health and safety All cornerstone objectives were met NRC plans baseline inspections at Watts Bar for the remainder of CY 2006
