Decontamination and Decommissioning

The Nuclear Regulatory Commission has approved the transfer of the Palisades nuclear power plant licenses from Entergy Nuclear Operations to Holtec International, as owner, and Holtec Decommissioning International (HDI), as decommissioning operator. Holtec and HDI intend to decommission the single-unit pressurized water reactor, located in Covert, Mich., under an accelerated schedule.

The Department of Energy’s Office of Environmental Management (EM) is set to complete the 69th building demolition at the West Valley Demonstration Project early next year, when crews finish knocking down the last structure standing that supported operations at the former Main Plant Process Building.

Markey

At an otherwise congenial Nuclear Regulatory Commission oversight hearing held last week by the Senate Environment and Public Works Committee, Sen. Ed Markey (D., Mass.) made clear his strong disagreement with the agency’s November 3 decision to approve a proposed rule amending regulations for nuclear plants undergoing decommissioning.

“I fear the NRC now stands for Not Recognizing Concerns,” Markey said. “The NRC has decided that the best way to shield itself from criticism around the decommissioning process is to take itself out of the process. In the latest version of the proposed decommissioning rule, the NRC would have no ability to approve, no ability to change, no ability to deny plants’ decommissioning proposals, known as post-shutdown decommissioning activities reports. Its only job would be to acknowledge receipt of the report. Our independent nuclear safety regulator would serve as a glorified filing cabinet. Ceding the job of regulator to the nuclear industry itself is not a win for safety, communities, or for the energy sector.”

The track record for the successful decommissioning of nuclear facilities, both nationally and internationally, is impressive. In the United States, we have decommissioned many nuclear facilities, including complex materials sites, uranium recovery sites, research and test reactors, and nuclear power plants. To date, according to the Nuclear Regulatory Commission, 10 nuclear power plants have been completely decommissioned for unrestricted use, and another 26 power reactor sites are currently undergoing decommissioning through either SAFSTOR or DECON, following NRC regulatory requirements. In addition, the Nuclear Energy Institute identifies three nuclear power plants that were successfully decommissioned outside of NRC jurisdiction. While such a track record is impressive, the nuclear industry must be vigilant in focusing on lessons learned in order to continue to make gains in efficiency, cost savings, improved environmental stewardship, and enhanced stakeholder confidence. In reviewing the outcomes of decommissioning over many years, a number of key lessons learned have emerged.

The U.S. Army Corps of Engineers (USACE), Baltimore District, is home to the North Atlantic Division’s Radiological Health Physics Regional (RHPR) Center of Expertise, which is leading the decommissioning of Army reactors.

From 1956 to 1976, the Army’s nuclear power program operated several small nuclear reactors to confirm the feasibility of their meeting military power needs on land. Three Army reactors were deactivated in the 1970s and placed into safe storage awaiting future decommissioning.

The license for Pacific Gas & Electric Company’s Humboldt Bay Unit 3 nuclear power plant near Eureka, Calif., has been terminated by the Nuclear Regulatory Commission, and the site has been released for unrestricted use. A 65-MWe boiling water reactor plant, Humboldt Bay-3 operated commercially from 1963 to 1976.

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.
