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.

The Nuclear Regulatory Commission has extended its orders transferring the licenses for the La Crosse and Zion nuclear power plants from EnergySolutions back to the plant owners until late 2022. This is the third time the NRC has extended the effectiveness of the license transfer orders for the decommissioned plants since approving them in 2019.

Pamela Cowen

Having spent more than 25 years in the commercial nuclear power community, Pam Cowan has spent time in both the front- and back-end operations of nuclear power. It is this experience that she draws upon as the senior vice president and chief operating officer of Holtec Decommissioning International (HDI) to help her build a growing fleet of power plants undergoing decommissioning and demolition.

Cowan, who came to HDI from the Nuclear Energy Institute, is also senior vice president of decommissioning and regulatory affairs for HDI parent company Holtec International and president of the Nuclear Asset Management Company, the owner of the plants. Cowan also serves as a member of the board of directors of Comprehensive Decommissioning International, a decommissioning general contractor, jointly owned by Holtec and SNC-Lavalin.

Radwaste Solutions spoke to Cowan about Holtec’s fleet approach to decommissioning and her plans for HDI.

(Editor's note: Soon after this article was published in Radwaste Solutions, Westinghouse Electric Company announced that Pam Cowan had been appointed president of the company's Americas operating plant services unit. Cowan takes over the business on September 21, following the retirement of current president, David Howell.)

NorthStar Group Services is being allowed to intervene in Wisconsin’s regulatory review of the sale of the Kewaunee nuclear power plant by Dominion Energy to EnergySolutions for decommissioning. An administrative law judge granted NorthStar permission on September 7 to participate in the Public Service Commission of Wisconsin’s review of the transaction.

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.

Westinghouse will segment and dispose of the reactor internals and pressure vessels at Sweden’s Ringhals-1 and Ringhals-2 under a deal announced last week with plant owner Vattenfall. Unit 2, a pressurized water reactor, and Unit 1, a boiling water reactor, were shut down in 2019 and 2020, respectively, after operating for more than 40 years.

The nuclear industry is rapidly embracing virtual reality (VR) technology to optimize operations and improve safety. VR companies build an interactive 3D virtually realistic environment where teams can be trained without compromising safety.

The Nuclear Regulatory Commission is holding a virtual meeting on August 18 to discuss and receive comments regarding Holtec International’s decommissioning plan for the Indian Point nuclear power plant in New York. A hybrid meeting was held on July 29 in Tarrytown, N.Y., with a phone line available for those who opted not to attend in person. However, local storms and technical issues resulted in remote participants experiencing audio problems.

The U.S. Army Corps of Engineers is set to begin decommissioning SM-1A, the mothballed nuclear power reactor at Fort Greely, in Alaska, beginning next year, a project that is expected to take approximately six years. The USACE said it expects to release a request for proposals soliciting contractor bids for the decommissioning and dismantlement project by late summer.

The U.K. government and EDF have agreed to improved arrangements for the decommissioning of Britain’s seven advanced gas-cooled reactor nuclear power plants, which are due to reach the end of their operational lives this decade.

The Nuclear Regulatory Commission has dismissed a challenge to the previously approved transfer of the license for the shuttered Three Mile Island-2 power reactor from FirstEnergy to a subsidiary of EnergySolutions for decommissioning. The order by the NRC commissioners denying the motion by Three Mile Island Alert to hold the license transfer in abeyance was issued on June 22.

Noting the challenges Japan will face in managing the nuclear waste that will be generated from decommissioning 79 of its nuclear research and development facilities, the International Atomic Energy Agency is recommending that the country prepare for delays in the development of disposal facilities and provide appropriate waste storage capacity for the interim period.

The recommendation was one of several that a team of IAEA experts provided to the Japan Atomic Energy Agency after reviewing the agency’s 70-year decommissioning program, called the “Back-End Roadmap,” and contained in the report, ARTEMIS Review of JAEA Back-End Roadmap, which was released on June 22,

A report by the OECD Nuclear Energy Agency proposes a new approach to assessing the financial adequacy for undertaking nuclear decontamination and decommissioning projects and high-level radioactive waste management.

With the world’s aging nuclear power reactors approaching the end of their planned operational lifetimes, the adequacy of funding for decommissioning and waste management increasingly commands the attention of decision makers, the NEA said.

Towed from its home in Newport News, Va., the U.S. Navy’s Surface Ship Support Barge has arrived in Mobile, Ala., for decommissioning, Advance Local Alabama reported on June 1. The 268-foot-long barge operated from 1964 to 2016, supporting the Navy's nuclear vessel refueling and functioning like a spent fuel pool at a commercial nuclear power plant.

The transfer of the Indian Point nuclear power plant from Entergy to Holtec International and its subsidiaries was completed last week. Under the asset transfer deal, Holtec Indian Point becomes owner of the closed plant, with Holtec Decommissioning International serving as the site’s license holder and decommissioning operator.

A collaboration agreement signed by Ontario Power Generation’s Center for Canadian Nuclear Sustainability, Canadian Nuclear Laboratories, and SNC-Lavalin will build on Ontario’s extensive nuclear industry expertise and skilled workforce to support the decommissioning of CANDU reactors in Canada and around the world, according to a May 13 press release from the organizations. The work will include the decommissioning of OPG’s Pickering nuclear power plant following the end of commercial operations in 2025.

At present, more than 20 commercial nuclear power plants in the United States have entered the decommissioning process, and many indicators point to a coming wave of additional plant closures. Indeed, with increasing numbers of plants terminating operations due to unfavorable market conditions, some voices have deemed this the “age of decommissioning.”

Regardless of whether a plant shuts its doors earlier than antici­pated or seeks a life extension through relicensing, all plants eventually close. When they do, the closure sets off a wave of economic impacts ranging from minor disruptions to severe and long-lasting harm.

Utah-based EnergySolutions has entered into a definitive agreement with Dominion Energy to acquire the closed Kewaunee nuclear power plant for prompt decommissioning. Located about 30 miles southeast of Green Bay, Wis., the single-unit, 574-MWe pressurized water reactor was shut down in May 2013 for financial reasons.

The Nuclear Regulatory Commission is set to allow about 2 million gallons of low-level radioactive wastewater from the Vermont Yankee nuclear power plant, currently undergoing decommissioning, to be disposed of at an Idaho waste facility. As published in the May 7 Federal Register, the NRC has issued an environmental assessment and finding of no significant impact for a request by NorthStar Nuclear Decommissioning to dispose of the wastewater at US Ecology Idaho’s waste facility near Grand View.

When on May 7, 2013, the Kewaunee nuclear power plant in rural Wisconsin was shut down, it took with it more than 600 full-time jobs and more than $70 million in lost wages, not including temporary employment from refueling and maintenance outages. Taking into account indirect business-to-business activity, the total economic impact of the closure of the single-unit pressurized water reactor was estimated to be more than $630 million to the surrounding three-county area.
