Orano USA announced that it has recently completed the transportation and disposal of the dismantled Crystal River Unit 3 reactor using only four large packages, which were shipped more than 1,800 miles each by barge and multi-axle trailer from the nuclear power reactor’s site on Florida’s west coast to Waste Control Specialists’ disposal facility in Andrews County, Texas.
The Department of Energy’s Office of Nuclear Energy has wrapped up testing of its Atlas railcar, successfully completing a round-trip journey from Pueblo, Colo., to Scoville, Idaho. Built to safety standards set by the Association of American Railroads (AAR), the 12-axle railcar is designed to transport large containers of spent nuclear fuel and high-level radioactive waste.
The Norwegian shipbuilding company Ulstein has developed a design concept for a cruise ship fueled by a molten salt nuclear reactor. In the company’s concept, the 500-foot-long, 60-passenger ship, named Thor—in reference to the Norse god as well as the thorium used in the reactor core–would generate its electricity with the onboard reactor. The ship would also serve as a charging station for a fully electric companion ship named Sif, named after the goddess who was Thor’s wife.
Price
Devon Price, Entergy Corporation’s nuclear fleet outage services director, works out of the company’s headquarters in Jackson, Miss. He and his family own property in Elkton, Md., which was where a stranger knocked on his front door. “He said he was an arborist and has a keen eye for gorgeous trees, and he asked if he could take a look at the Norway spruce behind the house,” Price recalled.
The request: No problem, Price said, and they went into the backyard to view the 79-foot tree with branches that spread to a 46-foot diameter at the base. Gradually, the man revealed who he was: Erik Pauzé, head gardener at Rockefeller Center in New York City.
“He said, ‘Ever hear of the Rockefeller Center Christmas tree? What would you think of letting this one go?’” Price recalled. Pauzé explained that it would be a donation and “would be a pretty big deal,” Price said.
The Nuclear Regulatory Commission is considering changes to its rules governing the transportation of radioactive materials, having received and docketed a petition for rulemaking from the Tribal Radioactive Materials Transportation Committee (TRMTC) asking that the agency revise its regulations on when tribal governments are provided advance notification of such shipments.
As announced in the April 9 Federal Register, the NRC is examining the issues raised in the petition to determine whether they should be considered in rulemaking. The NRC is also requesting public comments on the rulemaking petition, to be submitted by June 23.

Core Power is a tiny startup that is bullish on the prospects for nuclear-powered ocean transportation. The company announced on November 2 that it is part of a team that has applied for a cost-shared award from the Department of Energy’s Advanced Reactor Demonstration Program (ARDP) to build a prototype molten salt reactor (MSR). Core Power believes that MSRs could be used for propulsion or electricity generation to decarbonize the world’s commercial shipping fleet.
Based in London, England, Core Power is the only non-U.S. member of the team, which includes TerraPower, Southern Company, and Orano USA. As a marine engineering firm, Core Power says that it offers its ARDP partners “access to pent-up demand from a market with real customers.” An announcement of ARDP “risk reduction for future demonstrations” award winners is expected in December.
The government of the United Kingdom conducted a series of tests in the 1980s to assess the robustness of spent nuclear fuel packages. One such test involved ramming a 140-ton diesel locomotive into a transportation canister, called a nuclear flask, at 100 miles per hour. The test, according to a recent article published by the online magazine The Drive, was a “smashing” success. Just 0.29 psi of pressure escaped the 50-ton test flask, which had been pressurized to 100 psi.
As demands for a comprehensive U.S. waste management plan increase, private vendors are certifying new SNF/HLW transportation cask designs.
A large-scale campaign to move spent nuclear fuel and high-level radioactive waste in the United States to a central repository or interim storage site does not appear to be coming anytime soon. External pressures, however, including a growing number of nuclear power plant closures and increased stakeholder demand to remove stranded spent fuel and HLW, are shifting focus to building the infrastructure needed to move large volumes of waste. This includes the design and manufacture of shielded transportation casks for shipping the waste by truck or rail.
The NWTRB offers findings and recommendations to the DOE on technical issues that need to be addressed in preparing for an integrated, nationwide program to transport nuclear waste.
The U.S. Nuclear Waste Technical Review Board (NWTRB or Board) recently completed an evaluation of Department of Energy activities related to transporting spent nuclear fuel (SNF) and high-level radioactive waste. These topics have been the subject of several Board meetings and associated reports, and in September 2019, the Board issued a report, Preparing for Nuclear Waste Transportation–Technical Issues That Need to Be Addressed in Preparing for a Nationwide Effort to Transport Spent Nuclear Fuel and High-Level Radioactive Waste [1], which focuses on the issues DOE will need to address to plan and implement an integrated transportation program. In its report, the Board describes 30 broad technical issues that DOE needs to address and offers three sets of findings and recommendations.
