The Future of Diablo Canyon

The reports of the death of the Diablo Canyon nuclear power plant may be greatly exaggerated. While Pacific Gas and Electric (PG&E) announced as early as 2016 that it would be closing California’s last operating nuclear power plant at the end of its current operating license, there has been growing political pressure to keep the plant, and its 2,200 MWe of carbon-free energy, running.

Decommissioning San Onofre

Imagine it’s January 1998. A specially equipped train from the Department of Energy rolls up to the San Onofre Nuclear Generating Station (SONGS) to pick up spent nuclear fuel and take it to the Yucca Mountain repository in Nevada. This scene is repeated thousands of times at nuclear plant sites across the U.S. over the ensuing decades. The solution to permanent spent fuel disposal as outlined in the Nuclear Waste Policy Act (and its amendments) is working as intended. The nation’s commercial spent fuel is safely isolated deep underground for the long term.

But that is not what happened. Work on Yucca Mountain has been stalled for a full decade, and the organization within the DOE that by law is responsible for managing the spent fuel program has been defunded and disbanded.

A nearly yearlong effort to de-tension and remove more than 400 steel cables, known as tendons, from the two containment domes of the San Onofre Nuclear Generating Station (SONGS) was recently completed, with only one minor first aid incident recorded, according to Southern California Edison.

A bill introduced on September 21 by Rep. Mark Levine (D., Calif.) would direct the Department of Energy to conduct an advanced fuel cycle research, development, demonstration, and commercial application program. According to Levine, whose district includes the closed San Onofre Nuclear Generating Station (SONGS), the Spent Nuclear Fuel Solutions Research and Development Act (H.R. 8258) is intended to foster innovation in the storage and disposal of spent nuclear fuel.

The program, which would be authorized at over $500 million over five years, would have the DOE investigate a variety of options for managing the storage, use, and disposal of spent fuel, including dry cask storage, consolidated interim storage, deep geological storage and disposal, and vitrification.

Environmental Impact Evaluations – Seeing the Bigger (Nuclear vs. Fossil) Picture

DC PerspectivesAs I discussed last fall, a federal appeals court ordered the Nuclear Regulatory Commission to perform more thorough evaluations in support of its new Waste Confidence Rule, particularly with respect to the potential impacts of long-term storage of spent fuel at plant sites. While those evaluations are being performed, the NRC has suspended all new plant licensing and plant license renewals.

San Onofre debate now more public – and more technical

The debate over the continuing investigations into steam generator U-tube problems at San Onofre Nuclear Generating Station (SONGS) last week entered a new phase of heightened publicity and public scrutiny as the Nuclear Regulatory Commission (NRC) released Mitsubishi documents which detailed that company's investigations into the root causes of the problems.
