NRC Annual Performance Assessment of Vermont Yankee 2006 Reactor Oversight Process

2 Purpose of Todays Meeting Discuss Vermont Yankee Plant Performance for CY 2006 Provide Entergy management the opportunity to respond to the NRCs Annual Performance Assessment and to identify new or existing programs to continue to improve performance Provide stakeholders the opportunity to engage the NRC staff on plant performance issues and our role in ensuring safe plant operations

3 Agenda

• Introduction

• NRC organization and performance goals

• Reactor oversight process

• National summary of plant performance

• Vermont Yankee plant performance assessment

• Entergy managements response and remarks

• NRC closing remarks

• Break

• NRC available to address public questions

4 Region I Organization Samuel J. Collins Regional Administrator Marc L. Dapas Deputy Regional Administrator David C. Lew Director, Division of Reactor Projects James W. Clifford Deputy Director Marsha K. Gamberoni Director, Division of Reactor Safety Darrell J. Roberts Deputy Director Raymond Powell Branch Chief Regional Specialists Vermont Yankee Resident Inspectors David Pelton - SRI Beth Sienel - RI Project Engineers Barry Norris - Senior PE Nicole Sieller - PE

5 NRC Performance Goals

• Safety: Ensure protection of public health and safety and the environment

• Security: Ensure the secure use and management of radioactive materials

• Openness: Ensure openness in our regulatory process

• Effectiveness: Ensure NRC actions are effective, efficient, realistic, and timely

• Management: Ensure excellence in agency management to carry out NRCs strategic objective

13 NRC 2006 Inspection Activities Vermont Yankee

• 4887 hours0.0566 days <br />1.358 hours <br />0.00808 weeks <br />0.00186 months <br /> of inspection and related activities

• 2 resident inspectors on-site

• 12 regional inspections

• 3 major team inspections:

Power Uprate Component Design Bases Inspection Licensed Operator Requalification Inspection

14 NRC Performance Indicators and Inspection Findings

• All performance indicators for Vermont Yankee for CY 2006 were Green

• There were 6 findings for Vermont Yankee in CY 2006 - 5 Green (very low safety significance) and 1 White (low to moderate safety significance)

15 NRC Inspection Findings White, a failure to properly prepare and ship a package containing radioactive material in a manner that assured conformance with DOT radiation level limitations on the external surface of the package.

Green, a failure to correct a previously identified condition that allowed the continued accumulation of dust on a grounding resistor bank. This dust accumulation contributed to the inadvertent initiation of the east switchgear room CO2 fire suppression system, declaration of an Unusual Event, and performance of a rapid power reduction.

Green, a failure to incorporate operating experience into the preventive maintenance strategy for the reactor building closed cooling water system pump motor.

Green, a failure to conduct surveillance tests to verify 10 CFR 50, Appendix R (Fire protection Program) components remained in an operable condition.

Green, a failure to establish an adequate off-normal procedure to address degraded service water system flow conditions.

Green, a failure to correct a condition that caused flow oscillations in both the high pressure coolant injection system and the reactor core isolation cooling system.

16 NRC Annual Assessment Summary Vermont Yankee Entergy operated the plant safely and in a manner that preserved public health and safety and protected the environment Vermont Yankee plant performance was in the Licensee Response column of the NRCs Action Matrix for the first 3 quarters of 2006, and moved to the Regulatory Response column in the 4th quarter of 2006 due to a White finding All cornerstone objectives were fully met NRC plans baseline inspections and one supplemental inspection at Vermont Yankee for CY2007
