POpening remarks PPower uprate review process PInspection program PStatus of NRC review of the Vermont Yankee power uprate application PConcluding remarks PQuestions and answers Agenda 1

PWhy we are here tonight PWhat we hope to accomplish

Convey the robustness of power uprate review process and inspection program

Listen to your concerns Nuclear Regulatory Commission Protecting public health and safety 2

P What we will discuss

Where we are in the review process

Next steps and opportunities for public participation PWhat we are unable to discuss

Results of our review - More analysis and inspection are needed PWe will be back Nuclear Regulatory Commission 3

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

PAmendment request submitted PNRC reviews application for completeness PPublic Notification (Federal Register Notice)

- Public Comments & Hearing Rights PTechnical Safety and Regulatory Review

- Preparation of Safety Evaluation PLegal Review PPreparation and Issuance of Amendment License Amendment Process 5

PReview now conducted using a new Review Standard P17 technical groups in NRC involved P4000 staff-hours PReviews typically result in 100 to 200 questions to the plant owner PNRC has reviewed the engineering approach for power uprates used by General Electric (a key contractor supporting the power uprate)

Extended Power Uprate Review 6

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 Review Standard Factors Considered in Development of Review Standard

PDefines a disciplined process for and scope of EPU amendment reviews PPoints to guidance for technical review PIncludes template safety evaluations for documenting NRC review Purpose of the Review Standard 8

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

PReview Standard PReview of information submitted by plant owner and other material PQuestions to the licensee PPrevious experience with power uprates and generic topical reports POn-site audits, if appropriate PNRC conducts its own calculations Review Effort 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%

PThe plant owner must make the safety case for the power uprate PExtensive review effort by the NRC PReview Standard incorporates Maine Yankee Lessons Learned and operating experience PVermont Yankee is the first plant where NRC is using the new Review Standard Summary 13

Inspection Program Stu Richards NRC Manager responsible for Inspection Program

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

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

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 Previous Engineering Team Inspections 17

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

PSpecial 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 Inspection Activities for Power Uprates 18

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

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 Vermont Yankee Application 20

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