FirstEnergy Nuclear Operating Company Completes Root Cause Report on Davis-Besse Shield Building Cracking
Report Submitted to Nuclear Regulatory Commission
AKRON, Ohio, Feb. 28, 2012 /PRNewswire/ -- FirstEnergy Nuclear Operating Company (FENOC) announced today that it has completed its Root Cause Analysis Report regarding the cause of the tight cracks identified in portions of the Davis-Besse Nuclear Power Station Shield Building during its fall 2011 reactor head replacement outage. The report has been submitted to the Nuclear Regulatory Commission (NRC). This extensive evaluation supports earlier analysis that concludes the structural integrity of the Shield Building remains intact, and the building is able to perform its safety function.
FENOC's comprehensive 119-page root cause report indicates that absence of an exterior weatherproof coating on the Shield Building allowed moisture associated with the blizzard of January 1978 to migrate into the concrete, freeze and expand, causing tight, subsurface cracks in portions of the building. The root cause report concludes that the cracking occurred following the blizzard's combination of extreme weather conditions, which included three days of driving rain preceding a drastic temperature drop to around 0-degrees Fahrenheit and intense winds throughout the storm.
A team of industry-recognized structural concrete and causal analysis experts assisted Davis-Besse personnel with the comprehensive root cause investigation. The root cause report outlines a number of actions that will be taken by FENOC, including applying a weatherproof coating to protect the Shield Building's exterior walls, performing additional inspections to verify the cracks have not spread and developing a long-term building monitoring plan.
In the course of the root cause investigation, an exhaustive list of potential cracking causes was examined, including possible design, construction, environmental and operational issues. Thorough testing and analysis of numerous concrete samples conducted in support of the root cause demonstrated that the concrete in the Shield Building is sound and in good condition.
Davis-Besse is part of FirstEnergy Nuclear Operating Company, a subsidiary of FirstEnergy Corp. (NYSE: FE), which also operates the Beaver Valley Power Station in Shippingport, Pennsylvania, and the Perry Nuclear Power Plant in Perry, Ohio.

Actual results may differ materially due to: the speed and nature of increased competition in the electric utility industry, the impact of the regulatory process on the pending matters before FERC and in the various states in which we do business including, but not limited to, matters related to rates, the status of the PATH project in light of the PJM Interconnection, L.L.C., (PJM) direction to suspend work on the project pending review of its planning process, its re-evaluation of the need for the project and the uncertainty of the timing and amounts of any related capital expenditures, business and regulatory impacts from ATSI's realignment into PJM, economic or weather conditions affecting future sales and margins, changes in markets for energy services, changing energy and commodity market prices and availability, financial derivative reforms that could increase our liquidity needs and collateral costs, the continued ability of FirstEnergy's regulated utilities to collect transition and other costs, operation and maintenance costs being higher than anticipated, other legislative and regulatory changes, and revised environmental requirements, including possible

courts on December 30, 2011, and the effects of the EPA's MATS rules, the uncertainty of the timing and amounts of the capital expenditures that may arise in connection with any litigation including NSR litigation or potential regulatory initiatives or rulemakings (including that such expenditures could result in our decision to shut down or idle certain generating units), the uncertainty associated with the company's plan to retire its older unscrubbed regulated and competitive fossil units, including the impact on vendor commitments and PJM's review of the company's plans, adverse regulatory or legal decisions and outcomes with respect to our nuclear operations (including, but not limited to the revocation or non-renewal of necessary licenses, approvals or operating permits by the NRC including as a result of the incident at Japan's Fukushima Daiichi Nuclear Plant), issues that could result from our continuing investigation and analysis of the indications of cracking in the plant shield building at Davis-Besse, adverse legal decisions and outcomes related to Met-Ed's and Penelec's ability to recover certain transmission costs through their transmission service charge riders, the continuing availability of generating units and changes in their ability to operate at or near full capacity, replacement power costs being higher than anticipated or inadequately hedged, the ability to comply with applicable state and federal reliability standards and energy efficiency mandates, changes in customers' demand for power, including but not limited to, changes resulting from the implementation of state and federal energy efficiency mandates, the ability to accomplish or realize anticipated benefits from strategic goals, FirstEnergy's ability to improve electric commodity margins and the impact of, among other factors, the increased cost of fuel and fuel transportation on such margins, the ability to experience growth in the distribution business, the changing market conditions that could affect the value of assets held in FirstEnergy's NDTs, pension trusts and other trust funds, and cause FirstEnergy and its subsidiaries to make additional
