Waste Management

Orano TN Americas and South Korean special steel maker SeAH Besteel last week announced the completion and delivery of the first dual-purpose used nuclear fuel dry storage cask manufactured for a U.S. utility by the Korean company.

Following Orano’s purchase order in September 2019, SeAH Besteel established a mass production system for Orano’s dual-purpose casks in compliance with U.S. and international nuclear standards. Orano TN Americas is a subsidiary of France’s Orano NPS.

The Texas Commission on Environmental Quality is threatening enforcement action against the Department of Energy for failing to meet its obligations in removing containers of transuranic waste currently in temporary storage at Waste Control Specialists’ Federal Waste Facility in West Texas.

Work crews at the Department of Energy's Hanford Site recently completed the first transfer of test water from the Waste Treatment and Immobilization Plant's Effluent Management Facility to the nearby Liquid Effluent Retention Facility (LERF). The transfer of 6,000 gallons was the first simulation of the process that will be used to treat secondary liquid waste from the plant’s Low-Activity Waste Facility during operations to treat tank waste.

“This is a tremendous accomplishment that culminates years of work by our team and alumni toward being ready for hot commissioning,” said Valerie McCain, project director and senior vice president for Bechtel National, Inc. “It’s an important step for the entire Hanford team and our collective mission of protecting the Columbia River and its shoreline communities.”

Bechtel National is a contractor of the DOE's Office of Environmental Management's Office of River Protection.

The Department of Energy reported this month that the final container of legacy transuranic waste from the Savannah River Site arrived at the Waste Isolation Pilot Plant for permanent disposal on the afternoon of April 14. The shipment capped the end of a journey for 239 shipments that began in 2011.

In all, trucks that carried the shipments weighed a combined 11,402,000 pounds and travelled more than 347,000 miles to the WIPP site.

An independent review of Denmark’s radioactive waste management program by an International Atomic Energy Agency team found that the country has developed a robust and well-functioning system, but that the national program needs further refinement if it is to be effectively implemented.

The government of Denmark requested the review of its waste management program to fulfil its European Union obligations requiring an independent review of EU member states’ national radioactive waste management programs. The Danish parliament adopted a resolution outlining the policy goals and activities of its national program for safely managing radioactive waste and spent nuclear fuel in 2018.

“The momentum toward a new era of nuclear energy is predicated in part on government and industry claims that new technological solutions to nuclear waste are forthcoming. But challenges remain in their realization at the necessary scale,” writes freelance journalist Jenny Johnson in the article “Nuclear renaissance hinges on solving the waste issue."

Sandia National Laboratories engineers Emily Stein, left, and Paul Mariner discuss recent results from their Geologic Disposal Safety Assessment software framework.

Ten teams of scientists from across the globe, including teams from the United States, Canada, Germany, and Taiwan, are virtually comparing software tools developed to assess the safety performance of deep geologic repositories for nuclear waste. The virtual workshop, held this month, is being conducted by members of an international collaboration called Development of Coupled Models and their Validation against Experiments, or DECOVALEX.

“The DECOVALEX initiative creates an important framework for experts in repository sciences from around the world to test and improve simulation models that are important to assessing the safety of geologic disposal,” said Jens Birkholzer, chairman of the initiative and a senior scientist at Lawrence Berkeley National Laboratory.

Waste management start-up company Deep Isolation has launched an online campaign to educate the public about nuclear waste and gain support for solving the issue to protect the environment, increase energy security, and remove a barrier to nuclear energy.

The website Solve Nuclear Waste aims to increase awareness about the need for permanent nuclear waste disposal to help secure a clean energy future. Visitors to the site can sign a petition that the company will share with elected officials and decision-makers to demonstrate that the public cares about the issue.

Canada’s Nuclear Waste Management Organization (NWMO) has completed a deep borehole drilling program at the two sites in Ontario under investigation for potentially hosting a deep geological repository to hold the country’s spent nuclear fuel. The NWMO said that Canada’s top geoscientists are leading the studies, in which approximately eight kilometers of core samples were pulled from the bedrock in the Wabigoon-Ignace area and the Saugeen Ojibway Nation (SON)–South Bruce area.

The Waste Isolation Pilot Plant’s Emergency Operations Center (EOC) and Joint Information Center (JIC) were activated on April 9 following an abnormal event that occurred during routine waste handling at the Department of Energy’s WIPP repository for transuranic waste, near Carlsbad, N.M.

The Nuclear Regulatory Commission will integrate two separate rulemaking activities concerning the disposal of low-level radioactive waste, issuing a “re-proposed” rule that consolidates updates to 10 CFR Part 61, “Low-Level Radioactive Waste Disposal,” and proposed changes to the requirements for the near-surface disposal of greater-than-Class C (GTCC) waste.

Depending on the size and complexity of a decommissioning project, the transportation and disposal of radioactive waste will have an oversized impact on planning, schedule, and budget. The scope of decommissioning a site contaminated with radioactive material begins and ends with the proper and safe packaging of waste and subsequent transportation from the site to the final disposal location. Once all of the waste is gone from the site, the compliance exercise can be completed and the site released from controls (i.e., the radioactive materials license is terminated and the site is decommissioned).

Last fall, scientists from Sandia, Los Alamos, and Lawrence Berkeley national laboratories began the third phase of a years-long experiment to understand how salt and very salty water behave near hot nuclear waste containers in a salt-bed repository. Initiated in 2017, the Brine Availability Test in Salt (BATS) project is part of a spent nuclear fuel research campaign within the Department of Energy’s Office of Nuclear Energy (DOE-NE).

The Department of Energy’s new consent-based process for siting an interim storage facility for the nation’s spent nuclear fuel faces many challenges, but it could be successful if correctly implemented by the department, according to the panelists of the American Nuclear Society’s webinar “Spent Nuclear Fuel Management: Wasting Away or Chance for Progress?” ANS President Steve Nesbit moderated the webinar, held on March 23.

The Department of Energy recently awarded $24.7 million to Oak Ridge cleanup contractor UCOR for its work at the Oak Ridge site in Tennessee from April 2021 through October 2021, amounting to 98 percent of the available fee for the evaluation period.

Several antinuclear groups are challenging the Nuclear Regulatory Commission’s licensing of Interim Storage Partners’ (ISP) consolidated interim storage facility for spent nuclear fuel in Andrews, Texas, by filing briefs in the U.S. Court of Appeals for the District of Columbia Circuit on March 18. The groups appealing the license include Beyond Nuclear, Don’t Waste Michigan (a coalition of seven environmental groups), and Sierra Club.

The NRC granted ISP a license in September 2021, authorizing the company to receive, possess, transfer, and store up to 5,000 metric tons of spent fuel and 231.3 metric tons of greater-than-Class C radioactive waste for 40 years. ISP plans to expand the facility in seven additional phases, up to a total capacity of 40,000 metric tons of fuel.

Without a plan for addressing issues in completing construction projects at the Waste Isolation Pilot Plant in New Mexico, the Department of Energy cannot ensure that further cost increases and schedule delays will not continue, according to a report by the Government Accountability Office. In particular, the GAO said, the DOE has not developed a corrective action plan to address root causes identified for the rising cost and the delay in building a new ventilation system at the transuranic waste repository.

Westinghouse Electric Company and nuclear waste management company Perma-Fix Environmental Services plan to jointly develop a state-of-the-art advanced materials treatment facility in the United Kingdom. During the 2022 Waste Management Symposia, held last week in Phoenix, Ariz., the two companies signed a nonbinding agreement to cooperate on a facility that will provide low-level radioactive waste treatment services to the European market.

Have you ever been punished for something you didn’t do? It happens to most of us on occasion while growing up, especially if we have siblings. It’s not the end of the world, and it teaches a valuable lesson: Life is not fair. Nevertheless, when it happens, it really rankles you.

The “issue” of nuclear waste provides me with instant recall of those unpleasant childhood memories. Commercial nuclear power plants have been managing low-level waste and used nuclear fuel safely and efficiently since the beginning of the nuclear enterprise. Industry is adept at minimizing, packaging, transporting, and disposing of LLW. Used fuel is stored safely and securely at reactor sites, awaiting disposal.

Forty years ago, nuclear power plant operators entered into contracts with the federal government. The deal was simple. The operators would pay the U.S. government a lot of money, and the government would pick up the relatively small amount of used fuel and dispose of it in a geologic repository, beginning in 1998. The money changed hands, but the used fuel never did.

The organization of the commercial fuel cycle with the geographical separation of waste disposal facilities from other nuclear facilities is a historical artifact. There are large economic and institutional incentives to collocate many fuel cycle facilities with the repository. Similarly, there are large economic and institutional incentives to collocate proposed fission battery factories and nuclear hydrogen/synthetic fuel (synfuel) gigafactories with other waste management facilities (used fuel storage, low-level waste disposal, etc.) to create nuclear technology hubs that create economic savings, generate jobs and tax revenue, and simplify waste management.
