Constellation Energy has announced that it will seek to restart Unit 1 of the Three Mile Island nuclear power plant in Pennsylvania as part of an agreement with Microsoft to power that company’s data centers. Given the growing interest by tech companies in using clean, reliable nuclear power to meet their growing energy demands, the September 20 announcement to reopen TMI-1, which was shut down and defueled in 2019, was not a huge surprise.

Fatigue has been identified as a major risk factor in industrial accidents. According to the National Safety Council, 13 percent of workplace injuries can be attributed to fatigue.1 Other research indicates that working 12 hours per day is associated with a staggering 37 percent increase in risk of injury.2 Considering fatigue was a contributing factor to major nuclear accidents at Chernobyl and Three Mile Island, it makes sense that the Nuclear Regulatory Commission imposes hefty fines to ensure strict adherence to its fatigue management regulations—particularly, Code of Federal Regulations Title 10, Part 26, “Fitness for Duty Programs.”

The U.S. Navy’s Surface Ship Support Barge, converted in the 1960s from a WWII T2 tanker to a support barge to accept spent nuclear fuel during the refueling of nuclear aircraft carriers, was dismantled and disposed of by the nuclear decommissioning company APTIM as a first-of-its-kind vessel dismantlement project for the Navy. The project was executed under contract with Naval Sea Systems Command; however, regulatory oversight was accomplished through an interagency framework agreement between the U.S. Navy and the Nuclear Regulatory Commission.

Commercial nuclear power is illegal in Australia, and it has been since the 1990s. This past June, however, the country’s main opposition party announced plans to build seven commercial nuclear reactors in the 2030s and 2040s on sites presently occupied by aging coal-fired plants—should the party’s Liberal–National Coalition win power in federal elections next year. This statement has reignited a public debate regarding the potential role of nuclear energy in Australia.

Unit 2 at the Prairie Island nuclear power plant near Red Wing, Minn., underwent an outage in fall 2023, which included extensive work on the reactor vessel using a novel approach to replace baffle-former bolts and lower radial clevis insert bolts. The work relied on extensive analysis beforehand to determine which bolts to replace such that only the new bolts were structurally credited for performance of their safety function. This proactive approach eliminated the need for costly contingencies associated with inspections.
The once-proposed location of the Fulton HTGR, in relation to modern-day operating nuclear power plants.
Fulton Station was to be a two-unit high-temperature gas-cooled reactor that was originally planned to start commercial operation in 1981 for Unit 1 and in 1983 for Unit 2. Each reactor was to provide 1,160 MWe of power. The nuclear steam supply system (NSSS) and fuel were to be developed by General Atomics (GA), and engineering firm Stone & Webster was charged with handling the construction. The Philadelphia Electric Company (PECO) had big plans for Fulton Station, but ultimately, the plant was never built.

Sam Lochmann is a well-respected sergeant in the security department at the Wolf Creek nuclear power plant near Burlington, Kan. The plant, a 1,200-MWe Westinghouse pressurized water reactor operated by Wolf Creek Nuclear Operating Corporation (WCNOC), had its 26th refueling outage this past spring.
The USACE tackles the former military reactor in Alaska

With the recent mobilization at the site of the former SM-1A nuclear power plant at Fort Greely, Alaska, the Radiological Health Physics Regional Center of Expertise, located at the U.S. Army Corps of Engineers’ Baltimore District, began its work toward the decommissioning and dismantlement of its third nuclear power plant, this time located just 175 miles south of the Arctic Circle.
An internal memo explaining the history of ANS.
This year marks the 70th anniversary of the founding of the American Nuclear Society.
Plenty of sources incorrectly list our birthday, but the reality is that October 11, 1954, is the correct date for the establishment of ANS.
Understanding the forces driving and impacting the advancement of our clean nuclear energy future
American Nuclear Society Executive Director/Chief Executive Officer Craig Piercy speaks at the 2024 UWC opening plenary.
The 2024 Utility Working Conference brought together the nuclear industry’s best in August to discuss and learn from key developments, successes, opportunities, and needs in the sector. American Nuclear Society Executive Director/Chief Executive Officer Craig Piercy opened the conference and its first plenary by talking about the nuclear industry’s current momentum.

Focused on the post-cleanup management of closed Department of Energy sites, the DOE Office of Legacy Management (LM) is responsible for the long-term surveillance and maintenance of more than 100 sites across the United States and Puerto Rico associated with past radiological and nuclear material production and testing, and energy research—some dating from as early as the Manhattan Project. With cleanup completed, many of these sites have been put to beneficial reuse and repurposed as parks and nature preserves, where visitors can witness the return of thriving ecosystems.

Robotics is fast becoming a go-to for nuclear decommissioning advances, and several organizations working in West Cumbria, England, the hub of the United Kingdom’s energy sector, have formed a partnership to share insight and work together to address common challenges and opportunities. Cumbria Robotics Cluster is an ambitious initiative powered by the Industrial Solutions Hub (iSH) to harness and expand the region’s renowned capabilities in cutting-edge engineering and problem solving.
Decommissioning begins on the closed Wisconsin power plant

In October 2012, Dominion Energy announced it was closing the Kewaunee nuclear power plant, a two-loop 574-MWe pressurized water reactor located about 27 miles southeast of Green Bay, Wis., on the western shore of Lake Michigan. At the time, Dominion said the plant was running well, but that low wholesale electricity prices in the region made it uneconomical to continue operation of the single-unit merchant power plant.
