Introduction & Agenda

• Joe Hagan

- Opening Remarks

• Gary Leidich FirstEnergySenior Vice President- Operations

- FirstEnergy Perspective

• Greg Halnon Director- Fleet Regulatory Affairs

- Insurance Claim Timeline & Process

• Dan Pace Senior Vice President- Fleet Engineering

- Exponent & Mattson Report Analysis

• Joe Hagan

- Commitments & Concluding Remarks 3

FENOC is Committed to Safety m Lessons learned from the Davis-Besse event will not be forgotten

• Strongly committed to operating all nuclear facilities safely and responsibly

- Annual Safety Culture and Safety Conscious Work Environment (SCWE) survey scores remain strong

- World class fleet industrial safety performance in 2006

- Excellence Plans drive continued performance Safe Plant SaferPatins improvement Reliable Plant Operations 4

Plant Operations Reflect Safety Commitment

• Conservative operations lead to strong operating performance mEquipment improvements ensure continued safe, reliable operations

, Industry recognizes performance improvements Oprtonm Reliable Cost-Effective Plant Operations Plant Operations 5

FENOC Response Addresses Key Issues

• FENOC accepts full responsibility for the Davis-Besse event

- Root causes and corrective actions remain valid

• Expert reports do not impact safe and reliable operation of Davis-Besse or other nuclear plants

• Lessons learned are: Safe Plant Operations

= Formal Reviews

- Early Communications Reliable Gost-Effective Plant Operations Plant Operatioin 6

Gary Leidich FirstEnergy Senior Vice President - Operations

Corporate Commitment to Nuclear Safety is Strong

- Nuclear safety is at the forefront mCorporate confidence in FENOC with full authority to -operate facilities safely and reliably

- Interfaces across corporate organizations need to improve Emphasis on safety is the highest Sate Plant Saferatins priority at all levels of FirstEnergy Reliable Cost-Effective Plant Operations Plant Operations 8

FENOC Receives Reports Dec. 5- Feb. 23- Mar. 20- May 2 - Jun. 13 -

Exponent FENOC Exponent FENOC FENOC

& Mattson initiated Report responded responded draft reports CRto sent to to NRC to NRC circulated address NRC Request Demand NEIL for Info for Info Dec. 18-safety Exponent concern; May 4-Report NRC Mattson sent to notified Report NEIL sent to NRC

FENOC Considers Exponent Report

• Commercial and nuclear processes did not sufficiently interface

" Determined no safety or inspection concern existed

• Lacked sensitivity to regulatory interest

, Improved process being developed Safe Plant Operations Reliable Plant Operations 11

FENOC Addresses May 2

Response

- Response was:

- Narrowly focused on crack and cavity development

= Not an endorsement of the entire Exponent, Report Response did not sufficiently consider:

- Exponent's overall conclusions and Safe Plant Operations assumptions

- Operational data Reliable Cost-Effective Plant Operations Plant Operations 12

Dan Pace Senior Vice President, Fleet Engineering

FENOC Stands by Root Cause Reports mAnalyses of root causes:

- Provided comprehensive review of the Davis-Besse event

- Identified programmatic failures

- Not implementing boric acid corrosion control program properly caused head degradation

- Leakage detectable prior to 12RFO (2000)

= Generated comprehensive and SafP ant

.appropriate corrective actions Reliable Plant Opecrationsa 14

Exponent & Mattson Reports Were Not Root Causes

• Reflect expert testimony obtained for insurance claim process

• Exponent Report

- Evaluated timing and evolution of wastage development based on recent data

= Assessed ability to detect leakage in 12RFO (2000)

" Mattson Report Safe Plan Operations

- Provided expert testimony on boric acid control program Reliable Cost Effective Plant Operations Plant Operations 15

FENOC Performed Analysis of Exponent Report

" Key root cause team members participated in review

, Exponent Report statements evaluated against technical/

managerial root cause reports

= Impact on other root cause reports assessed

- Key differences highlighted Safe P Discussed findings with Exponent Team pSaei

- Corrective actions reaffirmed Reliable Plant Operations 16

FENOC Assessed Report Conclusions

- Exponent provided complex analysis of cracking/wastage on head

- BWXT Head Report

- Argonne National Laboratories Report

- Recent Boric Acid Corrosion Data

- Root causes based on observed operational data Safe Plant Orperations

- Exponent results do not fully explain observed operational data Re liab e Cost-Effective Plant Operations Plant Operations 17

Differences in Exponent Report and Root Cause Reports Noted

" Root cause reports conclude detectable leakage started prior to 2000

• Exponent analysis indicated degradation not detectable in 2000 FENOC stands by analyses OSePatont of root causes Reliable Plan Operatns 18

Mattson Report is Expert Testimony

" Contains'expert testimony about the industry and its boric acid control programs

" Some of Mattson's conclusions can not be endorsed

" Agree with basic premise that damage to the reactor head was not deliberate

" Endorsed conclusions do not conflict with:

- Root cause reports

- Licensee Event Report regarding the Reactor Pressure Vessel

- FENOC's response to Notice of Violation and Proposed Imposition of Civil Penalties 4 Reliatle Plant Operations 19

Report Conclusions Summarized

• FENOC stands by analyses of root causes

• Reports represent expert opinion

• Exponent Report provides detailed technical analysis

• FENOC disagrees with Exponent regarding when leakage was detectable N FENOC agrees damage to the reactor head was not deliberate OatiPnt Reliable 0* Cost Effec Plant Operations Plant Operz 20

Joe Hagan FENOC President & Chief Nuclear Officer

FENOC Commits to Actions

• Develop process to review reports prepared for commercial matters

• Provide Operational Experience to industry

• Improve NRC correspondence procedure

• Assess Regulatory Communications policy

• Develop lessons learned from May 2 response Safe Plant Operations Reliable Co Plant Operations Plan 22
