Agenda P Opening remarks P Power uprate review process P Inspection program P Status of NRC review of the Vermont Yankee power uprate application P Concluding remarks P Questions and answers 1

Nuclear Regulatory Commission Protecting public health and safety P Why we are here tonight P What we hope to accomplish

< Convey the robustness of power uprate review process and inspection program

< Listen to your concerns 2

Nuclear Regulatory Commission P What we will discuss

< Where we are in the review process

< Next steps and opportunities for public participation P What we are unable to discuss

< Results of our review - More analysis and inspection are needed P We will be back 3

Extended Power Uprate Review Process Tony McMurtray NRC Project Manager for the Power Uprate Program

License Amendment Process P Amendment request submitted P NRC reviews application for completeness P Public Notification (Federal Register Notice)

- Public Comments & Hearing Rights P Technical Safety and Regulatory Review

- Preparation of Safety Evaluation P Legal Review P Preparation and Issuance of Amendment 5

Extended Power Uprate Review P Review now conducted using a new Review Standard P 17 technical groups in NRC involved P 4000 staff-hours P Reviews typically result in 100 to 200 questions to the plant owner P NRC has reviewed the engineering approach for power uprates used by General Electric (a key contractor supporting the power uprate) 6

Review Standard Factors Considered in Development of Review Standard P Standard Review Plan for the review of the safety analysis reports for nuclear power plants P Maine Yankee Lessons Learned P Public comments P Lessons learned from previously reviewed EPU applications P Operating experience from plants with approved EPUs P Interactions with the Advisory Committee on Reactor Safeguards

Purpose of the Review Standard P Defines a disciplined process for and scope of EPU amendment reviews P Points to guidance for technical review P Includes template safety evaluations for documenting NRC review 8

Safety Review Process P The plant owner must provide sufficient justification that safety is maintained under uprated power conditions P Review is based on the current licensing basis for the plant P Vermont Yankee is the first plant where the NRC is using the Review Standard 9

Review Effort P Review Standard P Review of information submitted by plant owner and other material P Questions to the licensee P Previous experience with power uprates and generic topical reports P On-site audits, if appropriate P NRC conducts its own calculations 10

Previously Approved EPUs at Boiling Water Reactors Plant Year Approved Uprate %

Monticello 1998 6.3%

Hatch 1&2 1998 8% per unit Duane Arnold 2001 15.3%

Dresden 2&3 2001 17% per unit Quad Cities 1&2 2001 17.8% per unit Clinton 2002 20%

Brunswick 1&2 2002 15% per unit 11

Power Uprate Information Available at NRCs Public Website Http://www.nrc.gov/reactors/operating/licensing/power-uprates.html

Summary P The plant owner must make the safety case for the power uprate P Extensive review effort by the NRC P Review Standard incorporates Maine Yankee Lessons Learned and operating experience P Vermont Yankee is the first plant where NRC is using the new Review Standard 13

Inspection Program Stu Richards NRC Manager responsible for Inspection Program

Reactor Oversight Process P NRC inspectors onsite P Additional inspectors from the regional office P Plant parameters are also tracked by the NRC as indications of performance P If a plants performance declines NRC inspection and oversight increase P NRC conclusions about Vermont Yankee performance are available on the NRC website 15

Inspections Focused on Engineering P A number of NRC inspections have assessed Vermont Yankee engineering P NRCs inspection program requires an engineering inspection every 2 years P Vermont Yankees performance in the engineering area is considered to be generally good P By law, Vermont Yankee is required to report deficiencies that meet threshold criteria 16

Previous Engineering Team Inspections P Architect/Engineer inspection - 1997 P Followup to Architect/Engineer - 1997 P Basis for Maintaining Operations Process-1998 P Pre-ROP Engineering Core - 1998 P ROP Safety System Design - 2000 & 2002 17

NRC Regulatory Path VY Design Basis Reconstitution P NRC engaged VY for Design Basis Reconstitution in late 90's P NRC conducted an extensive review of the Licensees Design Basis Reconstitution P Inspections continue to review Design Basis P New NRC requirements imposed, as necessary

Inspection Activities for Power Uprates P Special inspections are conducted to support the NRC review of a power uprate which include the following areas:

- Flow assisted corrosion

- Erosion Corrosion programs

- Testing of safety functions

- Other areas based on NRC review of application 18

Status of NRC Review Rick Ennis NRC Project Manager for Vermont Yankee rxe@nrc.gov

Vermont Yankee Application P Application and 3 supplements submitted in September and October 2003 P Public meeting held in October 2003 P NRC determined more information was required P NRC accepted the application for review in February 2004 P NRC expects to complete its review by January 31, 2005 20

Status of Technical Review P NRC has already provided approximately 60 questions to Entergy as part of the technical review. Entergy responded on January 31, 2004 P We anticipate more questions as the detailed review continues 21

Opportunities for Public Involvement P Federal Register notice will be posted to the NRC Web site:

Www.nrc.gov/what-we-do/adjudicatory/hearing-license-applications.html Provides an opportunity to request a hearing 22

High Focus Issues P Steam dryer integrity P Flow-induced vibration issues P Flow-accelerated corrosion P Power uprate testing P Grid stability P Emergency core cooling system performance 23

Contact Information P NRC contact: Rick Ennis, rxe@nrc.gov P Power uprate review standard is available on the NRC Web site at www.nrc.gov/reactors/operating/licensing/power-uprates.html.

P Notice of opportunity to request a hearing will be available at www.nrc.gov/what-we-do/regulatory/adjudicatory/hearing-license-applications.html 24
