Decontamination and Decommissioning

Levin

On July 21, Rep. Mike Levin (D., Calif.), whose district includes the San Onofre Nuclear Generating Station (SONGS), announced with Rep. Rodney Davis (R., Ill.) the formation of the bipartisan House Spent Nuclear Fuel Solutions Caucus. The caucus, according to its members, seeks to address the challenges associated with stranded U.S. commercial spent fuel and to serve as a forum for those who want to make progress on the issue, regardless of whether they have a preferred solution.

Rep. Levin talked with Nuclear News staff writer Tim Gregoire about his goals for the caucus and finding an answer to the country’s spent nuclear fuel dilemma.

Wright

In a prerecorded video speech to last week’s Decommissioning Strategy Forum in Summerlin, Nev., Nuclear Regulatory Commission commissioner David Wright addressed public concerns about the growing number of utilities transferring their nuclear power reactor licenses to outside companies for accelerated decontamination and decommissioning after plant closure.

“While the NRC’s reactor decommissioning financial assurance program considers the potential for non-utility companies to conduct decommissioning, we have heard concerns about the use of these new license transfer models, given the significant acceleration of decommissioning schedules and withdrawals from decommissioning trust funds,” Wright said in his November 1 speech.

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.

The Nuclear Regulatory Commission on Wednesday approved a proposed rule to amend its regulations for nuclear power plants that are transitioning from operations to decommissioning. After changes requested by the NRC commissioners are made by agency staff, the proposed rule will be published in the Federal Register, initiating a 75-day comment period.

“A group of professionals having fun in the fields of decommissioning and environmental sciences for the nuclear industry.”

That’s how the ANS DESD describes itself on its website. The focus of this professional division is the development and use of skills and technologies needed for the optimal management of the end-­of-­life care (decommissioning, decontamination, and remediation), long-­term surveillance, and maintenance of nuclear installations, materials, facilities, and sites.

A team of scientists from the United Kingdom’s University of Bristol were given access to the Chernobyl nuclear power plant in Ukraine, advancing a project to train robots and artificial intelligence systems to measure radiation and create 3D maps.

A slideshow of the team’s visit to Chernobyl’s Unit 4 control room and New Safe Confinement structure, where they deployed radiation mapping and scanning sensors, including a LIDAR-equipped robot call Rooster, appears on Gizmodo.

Savannah River Nuclear Solutions (SRNS), the management and operations contractor for the Department of Energy’s Savannah River Site, has torn down a large industrial cooling tower at the site’s D Area complex. The cooling tower, built in 1952, is one of more than 30 structures being removed from SRS’s D Area as the DOE works to reduce the site’s footprint.

The demolition of the final of 18 DOE-owned buildings at the Energy Technology Engineering Center (ETEC) has been completed, according to the DOE. The ETEC is the former liquid metals research facility located at the Santa Susana Field Laboratory (SSFL), northwest of Los Angeles.
