Agenda

• Opening remarks

• Power uprate review process

• Inspection program

• Status of NRC review of the Vermont Yankee power uprate application

• Concluding remarks

• Questions and answers

fI Ei Nuclear Regulatory Commission Protecting public health and safety

• Why we are here tonight

• What we hope to accomplish

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

• Listen to your concerns

Nuclear Regulatory Commission L: .1 -- r 77- - -.

• What we will discuss

• Where we are in the review process

• Next steps and opportunities for public participation

• What we are unable to discuss

• Results of our review - More analysis and inspection are needed

• We will be back

Extended Power Uprate Review Process William H. Ruland Project Directorate Ill Division of Licensing Project Management Office of Nuclear Reactor Regulation

License Amendment Process Amendment request submitted by licensee

• NRC reviews application for completeness

• Public Notification (Federal Register Notice)

- Public Comments & Hearing Rights

• Technical Safety and Regulatory Review

- Preparation of Safety Evaluation

• Administrative and Legal Review

• Preparation and Issuance of Amendment

Extended Power Uprate Review

• Review now conducted using a new Review Standard

• 17 different technical groups in NRR involved in review

• 4000 staff-hours

• Reviews typically result in 100 to 200 questions to the licensee

Review Standard Factors Considered in Development of Review Standard

• Standard Review Plan for the review of the safety analysis reports for nuclear power plants

• Maine Yankee Lessons Learned

• Public comments

• Lessons learned from previously reviewed EPU applications

• Operating experience from plants with approved EPUs

Purpose of the Review Standard

• Defines a disciplined process for and scope of EPU amendment reviews

• Points to guidance for technical review

• Includes template safety evaluations for documenting NRC review

Safety Review Process

-, , ,, * , * = - , -- - - I,, -, ,

• The licensee must provide sufficient justification that safety is maintained under uprated power conditions

• Review is based on the current licensing basis for the plant

-Vermont Yankee Is the first plant where the NRC is using the Review Standard

Review Effort

• Review Standard

• Review of information submitted by licensee and other material

• Questions to the licensee

• Previous experience with power uprates and generic topical reports

• On-site audits of licensee and contractor programs, if appropriate

• NRC conducts independent calculations

Summary

• Licensee must make the safety case for the power uprate

• Extensive review effort by the NRC

• Review Standard incorporates Maine Yankee Lessons Learned and operating experience

• Vermont Yankee is the first plant where NRC is using the new Review Standard

Inspection Program If Reactor Oversight Process t:'. _^ Y e 5 = D -~ ---4

• NRC inspectors onsite mAdditional inspectors from the regional office conduct inspections

- Plant performance indicators are also tracked by the NRC as indications of performance

• If a plant's performance decreases, NRC inspection and oversight increase

• NRC conclusions about Vermont Yankee w_ ale is w1 - : I I o A- .4 A-% I D -N

Inspections Focused on Engineering Assessment mA number of NRC inspections have assessed Vermont Yankee engineering

• NRC's inspection program requires an engineering inspection every 2 years

• Vermont Yankee's performance in the engineering area is considered to be xx

• By law, Vermont Yankee is required to report deficiencies that meet threshold criteria

Previous Engineering Team

_- .n Inspections- - T -

• Architect/Engineer inspection 1997

• Followup to Architect/Engineer - 1997

• Basis for Maintaining Operations Process-1 998

• Pre-ROP Engineering Core - 1998

• ROP Safety System Design - 2000 & 2002

Inspection Activities for Power U prates

• Special inspections are conducted to support the NRC review of a power uprate which look at the following areas:

- Flow assisted corrosion

- Erosion Corrosion programs

- Integrated testing to verify safety functions

- Other areas based on NRC review of application

• NRC has also reviewed the engineering approach for power uprates used by General Electric (a key contractor supporting the power uprate)

Status of NRC Review Rick Ennis Senior Project Manager Office of Nuclear Reactor Regulation rxe @ nrc gov

Vermont Yankee Application

• Application and 3 supplements submitted in September and October 2003

• Public meeting held in October 2003

• NRC determined more information was required

• NRC accepted the application for review in February 2004

• Review completion date forecast for Jan. 31, 2005

Status of Technical Review

• NRC has already provided approximately 60 questions to Entergy as part of the technical review. Entergy responded on January 31, 2004

• We anticipate more questions as the detailed review continues

Opportunities for Public Involvement

• 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 for public comments or request for a hearing

High Focus Issues

• Steam dryer integrity

• Flow-induced vibration issues

• Flow-accelerated corrosion

• Power uprate testing

• Grid stability

• Emergency core cooling system performance
