NRC Will Make Sure FirstEnergy Got It Right: What Caused the Cracks in the Davis-Besse Nuclear Plant’s Shield Building?

What caused the cracks in the shield building at the Davis-Besse nuclear plant and what needs to be done to ensure the building’s long-term safety? The NRC’s current inspection is focused on making sure we are satisfied with FirstEnergy’s answers to these questions.

We’ve previously written about the NRC’s exhaustive efforts to ensure the cracks found in the shield building around the Davis-Besse nuclear power plant’s containment structure are not compromising current safety. We will continue to take the necessary steps during the current inspection to make sure that the reasons for these cracks are well understood and FirstEnergy’s proposed actions to ensure the building’s long-term safety will accomplish this goal.

First, we studied the initial review done by the plant’s owner – FirstEnergy – in their root cause analysis to gain a better understanding of how the company arrived at its conclusions.

Then, a team of four NRC inspectors went to the plant with about 80 questions associated with this initial review. They recently finished a week-long inspection verifying the initial information and questioning the company’s conclusions. While at the plant, the NRC inspectors also reexamined the condition of the shield building.

By the time the company submitted the root-cause report to the NRC on February 28, in accordance with the plant’s commitment to the agency, our inspectors had already completed observations and verification of the company’s shield building testing. Months before, NRC inspectors had traveled to laboratories in California and Colorado to directly observe tests of concrete samples removed from the Davis-Besse shield building. These tests are a key component of the cracking analysis and NRC inspectors need to have confidence in their quality.

The NRC’s actions to accomplish an in-depth review of FirstEnergy’s root cause submittal involve further actions:

• examining key aspects of the analyses performed by the company’s contractor to support the FirstEnergy’s root cause conclusions;

• making sure First Energy considered all possible causes of cracking based on inputs from multiple sources such as the industry’s and the company’s operating experience; and

• thoroughly evaluating the company’s proposed corrective actions to make sure they are sufficient to maintain the long-term safety of shield building.

The NRC’s independent inspection will continue to challenge the company’s the root cause report and planned corrective actions until we have confidence in their thoroughness and accuracy.

The NRC will discuss its conclusions on the adequacy of FirstEnergy’s root cause analysis and proposed corrective actions at a public meeting to be scheduled after we complete our inspection. The details of this inspection will be outlined in a publically available report.

Asking the public for input on the FY 2012 proposed fee rule

Once again, we are looking to hear from the public about proposed changes to our fee rule.

The agency is required by law to recover approximately 90 percent of our budget through fees to licensees and applicants. To accomplish this, each year we publish a rule that establishes the fees in a way that recoups the cost of “doing business” for the NRC.

There are two types of fees: licensee-specific and annual fees. Both types of fees incorporate the cost of the program oversight and agency overhead. Licensee-specific fees are based on hourly rates to recover the costs of specific services, such as reviewing applications and performing inspections. Annual fees recover all other costs.

For FY 2012, the NRC received about $1 billion. Based on this amount, the NRC must recover about $909.5 million directly from those we regulate by Sept. 30. In our regulations, approximately 40 percent of the fees will be billed for licensee-specific services and the remaining 60 percent will be billed as annual fees.

The proposed fee rule includes several changes. First, we are proposing to change the current hourly rate slightly from $273 to $274. Second, we would revise the flat license application fees (found in our federal guidelines 10 CFR Parts 170.21 and 170.31) to reflect the new hourly rate. Finally,we would revise annual fees, as appropriate, for all licensees.

We also propose that the annual fees would increase for some licenses, such as for most material users, fuel facilities and transportation, and would decrease for operating nuclear reactors, research and test reactors, spent fuel storage facilities and most uranium recovery licenses.

We continue efforts to keep our fees as low as possible by ensuring our programs are conducted efficiently and effectively, and we request from Congress only the resources necessary to perform our mission of protecting people and the environment
