February 22, 2021, 9:29AMRadwaste Solutions

The Environmental Protection Agency has awarded three contracts for cleanup efforts at more than 50 abandoned uranium mine sites in and around the Navajo Nation in the southwestern United States. The Navaho Area Abandoned Mine Remedial Construction and Services Contracts, worth up to $220 million over the next five years, were awarded to the Red Rock Remediation Joint Venture, Environmental Quality Management, and Arrowhead Contracting, the agency announced on February 11.

According to the EPA, the cleanup work is slated to begin later this year, following the completion of assessments in coordination with the Navajo Nation EPA, the tribe’s environmental agency. The sites are in New Mexico’s Grants Mining District and 10 Navajo Nation chapters. The companies selected have experience working on hazardous waste sites across the country, including cleaning up other abandoned mine sites in the Southwest, the EPA said.

Hanford subcontractor to support transfer of radioactive capsules to dry storage

February 17, 2021, 9:30AMRadwaste Solutions

A subcontractor has been selected to continue making modifications to a Hanford facility to transfer nearly 2,000 highly radioactive capsules to safer interim dry storage.

Central Plateau Cleanup Company, the Department of Energy’s prime cleanup contractor for the Central Plateau area of the Hanford Site, near Richland, Wash., recently awarded a $9.5 million construction subcontract to Apollo Mechanical Contractors. Apollo will continue work on the site’s Waste Encapsulation and Storage Facility (WESF), where nearly 2,000 highly radioactive capsules containing cesium and strontium are stored underwater.

Apollo will modify the WESF and install equipment needed to transfer the radioactive capsules from a water-filled basin to safer interim dry storage. In the 1970s, to reduce the temperature of the waste inside Hanford’s waste tanks, cesium and strontium were removed from the tanks and moved to the WESF. The DOE expects that the transfer of the capsules to dry storage will be completed by 2025.

“While the 1,936 cesium and strontium capsules are currently in safe storage, WESF is an aging facility,” said Gary Pyles, project manager for the DOE’s Richland Operations Office. “Moving the capsules will enable the planned deactivation of WESF and will reduce the risk and significantly reduce the annual costs for storing the capsules.”

Beyond Nuclear appeals NRC decision in Texas CISF licensing proceeding

February 16, 2021, 2:57PMRadwaste Solutions

The antinuclear organization Beyond Nuclear is appealing the Nuclear Regulatory Commission’s dismissal of its petition to intervene in the proceeding for Interim Storage Partners’ (ISP) application to build and operate a consolidated interim storage facility (CISF) for spent nuclear fuel in western Texas. Beyond Nuclear filed suit in the U.S. Court of Appeals for the District of Columbia Circuit on February 10, asking the court to order the dismissal of the license application.

ISP, a joint venture of Waste Control Specialists (WCS) and Orano, submitted its application for the CISF with the NRC in June 2018. In September 2018, Beyond Nuclear filed a motion to dismiss the application. An NRC Atomic Safety and Licensing Board denied Beyond Nuclear’s request for a hearing in the licensing proceedings, and in December 2020, the NRC issued an order upholding that decision.

The Association of American Railroads (AAR) recently gave the Department of Energy approval to begin building and testing Fortis, a high-tech railcar designed specifically to transport the nation’s spent nuclear fuel and high-level radioactive waste. Fortis is one of two specialized railcars under development by the DOE that could be operational within the next five years.

Fortis is an eight-axle, flat-deck railcar that will be able to transport large containers of spent fuel and HLW. It is equipped with high-tech sensors and monitoring systems that report 11 different performance features back to the operators in real time. The railcar design was completed earlier this year, with technical support from Pacific Northwest National Laboratory.

According to the DOE, AAR signed off on the design in January, allowing the department to begin fabricating and testing the prototype in compliance with the rail industry’s highest design standard for railcars transporting spent fuel and HLW.

NRC report updates decommissioning cost guidance

February 8, 2021, 9:12AMRadwaste Solutions

The Nuclear Regulatory Commission has updated its guidance for nuclear power plant owners and operators in estimating the cost of decommissioning their reactors. Licensed power reactor operators are required under NRC regulations to annually adjust the estimated costs (in current year dollars) of decommissioning their plants to ensure that adequate funds are available when needed.

NUREG-1307, Revision 18, Report on Waste Burial Charges: Changes in Decommissioning Waste Disposal Costs at Low-Level Waste Burial Facilities, issued on February 3, explains the formula acceptable to the NRC for determining the minimum decommissioning fund requirements for nuclear power reactor licensees. Specifically, NUREG-1307 provides the adjustment factor and updates the values for the labor, energy, and waste burial escalation factors of the minimum formula.

NNSA extends comment period on scope of “dilute and dispose” EIS

February 4, 2021, 12:00PMRadwaste Solutions

The Department of Energy’s National Nuclear Security Administration has extended to February 18 the public comment period for the scoping of its planned environmental impact statement (EIS) for the Surplus Plutonium Disposition Program, which would dilute and dispose of 34 metric tons of surplus military grade plutonium.

The NNSA on December 16 announced its intent to prepare the EIS, which will examine the agency’s preferred alternative, “dilute and dispose,” also known as “plutonium downblending,” and other alternatives for disposing of the material. The NNSA has been pursuing the dilute-and-dispose approach to managing the surplus plutonium following the cancellation of the MOX Fuel Fabrication Facility at the DOE’s Savannah River Site.

Study finds Estonia’s geology suitable for borehole repository

February 3, 2021, 9:29AMRadwaste Solutions

A preliminary study conducted by the nuclear waste storage and disposal startup company Deep Isolation found that Estonia’s geology is capable of safely hosting a deep horizontal borehole repository for radioactive waste from advanced nuclear reactors.

The study, commissioned by advanced reactor deployment company Fermi Energia, found no fundamental geologic limitations to disposing of nuclear waste in deep horizontal boreholes, according to Deep Isolation. In addition, the study noted that a wide range of locations could be demonstrated to comply with International Atomic Energy Agency regulations for geologic disposal.

The findings: Results of the study, which was conducted in collaboration with Estonian geologic and drilling company Engineering Bureau STEIGER, will be presented as part of Fermi Energia’s one-day conference on small modular reactors, "New Generation Nuclear Energy in Estonia," on February 9. Registration for the event is available online.

ANS weighs in on NNSA’s Pu disposition plan

February 1, 2021, 12:00PMRadwaste Solutions

The American Nuclear Society is urging the National Nuclear Security Administration to rethink its “dilute-and-dispose” plan for managing surplus weapons-grade plutonium. In comments submitted to the NNSA, ANS notes that a better solution for the agency’s inventory of surplus plutonium is to convert it to nuclear fuel for advanced reactors, as was originally intended.

The comments are in response to a December 16 Federal Register notice by the NNSA that it intends to prepare an environmental impact statement on the scope of its Surplus Plutonium Disposition Program. According to the notice, the NNSA intends to dispose of the entire 34 metric tons of surplus plutonium using its dilute-and-dispose approach, whereby the material will be downblended and shipped as transuranic waste to the Department of Energy’s Waste Isolation Pilot Plant (WIPP) in New Mexico.

Under the Plutonium Management and Disposition Agreement, signed by the United States and Russia in 2000, the 34 tons of plutonium was to be converted to mixed-oxide nuclear fuel using the MOX Fuel Fabrication Facility at the Savannah River Site, in South Carolina. However, the Obama administration, citing rising costs, halted construction on the facility in 2016, and the project was eventually canceled in 2019.

Columbia University report sets out nuclear waste policy options

February 1, 2021, 9:29AMRadwaste Solutions

A new report out of Columbia University’s Center on Global Energy Policy (CGEP) offers a number of recommendations for improving the management of spent nuclear fuel and high-level radioactive waste in the United States.

The report, Forging a Path Forward on U.S. Nuclear Waste Management: Options for Policy Makers, explains how the United States reached its current stalemate over nuclear waste disposal. It then examines productive approaches in other countries, and a few domestic ones, that could guide policymakers through options for improving the prospects for finding a disposal path for U.S. spent fuel and HLW.

Part of the center’s wider work on nuclear energy, the report echoes previous recommendations for U.S. spent fuel and HLW management, such as the use of a consent-based siting process and the formation of an independent waste management organization, both of which were recommended in the Blue Ribbon Commission’s 2012 report to the Secretary of Energy and Stanford University’s 2018 report, Reset of U.S. Nuclear Waste Management Strategy and Policy.

Jennifer Granholm, President Joe Biden’s nominee for energy secretary, told a Congressional panel that the administration disapproves of Yucca Mountain as the country’s nuclear waste repository, preferring a consent-based strategy as proposed by President Barack Obama’s Blue Ribbon Commission on America’s Nuclear Future.

“The administration opposes the use of Yucca Mountain for the storage of nuclear waste,” Granholm told Sen. Catherine Cortez Masto (D., Nev.), during a confirmation hearing before the Senate Energy and Natural Resources Committee on January 27.

Granholm, a Democrat, served two terms as Michigan governor from 2003 to 2011. According to reports, Granholm was twice considered a candidate to be energy secretary under President Obama, but ultimately was not picked.

The Department of Energy’s Oak Ridge Office of Environmental Management and its contractor UCOR have found a way to reuse instead of dispose of mercury collected from a cleanup project at the Y-12 National Security Complex, near Oak Ridge National Laboratory in Tennessee. “This questioning attitude and innovative thinking by our workforce is a major contributor to how our program is able to accomplish its projects under budget and ahead of schedule on a consistent basis,” said OREM manager Jay Mullis.

The DOE is conducting a number of projects to address mercury contamination—the most significant environmental risk is at Y-12, according to the agency. The work includes the cleanout and removal of equipment at Y-12's Alpha-4, a building that was used initially for uranium separation in 1944 and 1945. Ten years later, the building started being used for lithium separation, a process that required large amounts of mercury and involved column exchange (COLEX) equipment. Over the years, a significant amount of mercury from the process leached into the equipment, buildings, and surrounding soils.

New York Attorney General Letitia James filed a lawsuit on behalf of the State of New York against the Nuclear Regulatory Commission over the sale of the Indian Point nuclear power plant to subsidiaries of Holtec International for decommissioning.

Filed in the U.S. Court of Appeals for the District of Columbia Circuit on January 22, the suit challenges the NRC’s denial of New York’s petition for a hearing regarding the transfer of Indian Point’s licenses from owner Entergy to Holtec, as well as the NRC’s initial approval of the license transfer. The NRC approved the transfer in November 2020 while challenges from the state and other groups were still being adjudicated. The NRC issued its order denying New York’s petition to intervene on January 15.

The transfer of ownership of the plant from Entergy to Holtec is targeted to occur after Indian Point-3 shuts down in April 2021. Indian Point-2 permanently ceased operations in April 2020, and Indian Point-1 has been shut down since 1974. The pressurized-water reactors are located in Buchanan, N.Y., approximately 24 miles north of New York City.

The four-year collaboration on new robotics and automation techniques will also be applied to fusion energy research in the two countries.

Funded equally by U.K. Research and Innovation, the U.K.’s Nuclear Decommissioning Authority, and Japan’s Tokyo Electric Power Company, the LongOps project will be led by the U.K. Atomic Energy Authority’s (UKAEA) Remote Applications in Challenging Environments (RACE) facility.

DOE looks to dispose of Savannah River process equipment as LLW

January 21, 2021, 6:57AMRadwaste Solutions

The Department of Energy is considering disposing of contaminated process equipment from its Savannah River Site (SRS) at a commercial low-level waste facility using its recent interpretation of the statutory term “high-level radioactive waste,” which classifies waste generated from the reprocessing of spent nuclear fuel based on its radiological content rather than its origin.

U.S., Canada complete nuclear material shipping effort

January 13, 2021, 7:02AMRadwaste Solutions

A four-year campaign to repatriate 161 kilograms of highly enriched uranium liquid target residue material (TRM) from Chalk River Laboratories in Ontario, Canada, to the Savannah River Site in Aiken, S.C., has been completed, the National Nuclear Security Administration (NNSA) and Atomic Energy of Canada Limited (AECL) announced on January 12.

The campaign was conducted under the U.S.-Origin Foreign Research Reactor Spent Nuclear Fuel Acceptance Program, established in 1996 to return U.S.-origin spent nuclear fuel and other weapons-grade nuclear material from civilian sites worldwide. Other partners involved in the effort included the Department of Energy’s Office of Environmental Management (EM), Canadian Nuclear Laboratories, Savannah River Nuclear Solutions (SRNS), and Savannah River National Laboratory as well as state and tribal governments.

The TRM is the by-product of the production of medical isotopes from AECL’s now-shuttered National Research Universal reactor. The repatriation of the material, begun in 2017 and completed in 2020, involved 115 separate truck shipments, covering some 150,000 miles, according to the announcements.
