Some of the major achievements of the nuclear safety cooperation agreement between the International Atomic Energy Agency and the European Union (EU) include more than 100 nuclear safety review missions, environmental remediation at former uranium sites in Central Asia, and more effective radioactive waste management in Africa.

To prevent future winter storms from causing the kind of widespread, lethal power outages wrought by February’s frigid blast through Texas and other states, the electric and natural gas industries need to bolster their winterization and cold weather preparedness and coordination, a just-released preliminary report from the Federal Energy Regulatory Commission and North American Electric Reliability Corporation concludes.
The two agencies had announced on February 16 that they planned to open a joint inquiry to identify problems with the performance of the bulk power system during the storm and to offer solutions. A team of FERC and NERC staff members presented the report at a FERC meeting on September 23.
A presentation of the report, February 2021 Cold Weather Grid Operations: Preliminary Findings and Recommendations, is available.

Back in July, officials from the state of Tennessee and Kairos Power met in Nashville to celebrate Kairos’s plans to construct a low-power demonstration reactor in the East Tennessee Technology Park in Oak Ridge, Tenn. The demonstration facility is a scaled-down version of Kairos’s Fluoride Salt–Cooled High Temperature Reactor (KP-FHR), dubbed Hermes. The company first announced plans in December 2020 to redevelop the ETTP’s former K-33 gaseous diffusion plant site for construction of Hermes.
The U.S. NRC headquarters.
The staff of the Nuclear Regulatory Commission recently released a draft white paper outlining strategies for streamlining microreactor licensing. The paper is to be used to facilitate discussion at an upcoming advanced reactor stakeholder public meeting.
“This paper,” the document emphasizes, “has not been subject to NRC management and legal reviews and approvals, and its contents are subject to change and should not be interpreted as official agency positions.”

The Department of Energy’s Office of Environmental Management (EM) is managing the release of tritiated water using a 62-acre plantation of pine trees and other natural resources to limit radioactively contaminated groundwater from reaching waterways on the Savannah River Site in South Carolina.

For years, pressure has been building for a commercial path to a stable supply of high-assay low-enriched uranium (HALEU)—deemed essential for the deployment of advanced power reactors—but advanced reactor developers and enrichment companies are still watching and waiting. In contrast, the uranium spot price soared after Sprott Physical Uranium Trust, a Canadian investment fund formed in July, began buying up U3O8 supplies, causing the price to increase over 60 percent, topping $50 per pound for the first time since 2012. Fueled by growing acknowledgment that nuclear power is a necessary part of a clean energy future, uranium is the focus of attention from Wall Street to Capitol Hill.

U.S. energy secretary Jennifer Granholm and International Atomic Energy Agency director general Rafael Mariano Grossi met in Vienna yesterday during the agency’s 65th General Conference to launch preparations for the next IAEA International Ministerial Conference on Nuclear Power in the 21st Century, slated for October 26–28, 2022, in Washington, D.C.

Scientists at Lawrence Livermore National Laboratory, working in collaboration with researchers at Penn State University and Harvard Medical School, have discovered a new mechanism by which radionuclides could spread in the environment.
The research, which has implications for nuclear waste management and environmental chemistry, was published in the Journal of the American Chemical Society on September 20.
Having completed three separate decommissioning projects, EnergySolutions takes the final steps in restoring the sites to a natural state.
For any nuclear power plant that has been permanently shut down, site restoration is the ultimate decommissioning goal when contracting with a utility to demolish a facility. The task, however, is not as simple as mobilizing heavy equipment and waving a wrecking ball or planting explosives to implode the facility, then loading up the debris and sending it to a landfill.
There is a real science and engineering approach necessary to safely restore the land to its original state. That has been the goal for EnergySolutions over the past decade as the company works to safely decommission shuttered nuclear power plants—packaging, transporting, and disposing of the waste, and restoring the sites for whatever reuse the owners and host communities see fit.

The German government has announced that it is closing the Gorleben salt mine in the Wendland region of Lower Saxony, officially removing the site from consideration as a repository for radioactive waste. Gorleben became a target of antinuclear protests after being proposed as a potential repository in the 1970s.

For more than two decades, the American Nuclear Society’s Standards Committee has recognized the benefit of incorporating risk-informed and performance-based (RIPB) methodology into ANS standards to improve their effectiveness, efficiency, and transparency. In general, standards using RIPB methods with properly identified and structured objectives need less modification and can be expected to remain valid for much longer periods.
