The Sturgis is towed from the Galveston, Texas, pier to the shipping channel on September 25, 2018, as it heads toward Brownsville, Texas, for final shipbreaking and recycling. Over the past three years in Galveston, the U.S. Army Corps of Engineers has been implementing the challenging and complex effort to decommission the MH-1A—the deactivated nuclear reactor that was onboard the Sturgis vessel.
The U.S. Army Corps of Engineers (USACE), Baltimore District, is home to the North Atlantic Division’s Radiological Health Physics Regional (RHPR) Center of Expertise, which is leading the decommissioning of Army reactors.
From 1956 to 1976, the Army’s nuclear power program operated several small nuclear reactors to confirm the feasibility of their meeting military power needs on land. Three Army reactors were deactivated in the 1970s and placed into safe storage awaiting future decommissioning.

The American Nuclear Society supports the continued operation of California's Diablo Canyon nuclear power plant. The premature shutdown of Diablo Canyon units 1 and 2, slated respectively in November 2024 and August 2025, will inflict grave harm to California's economy and environment.
Millstone nuclear power plant
The Nuclear Regulatory Commission has granted Dominion Energy’s request for an increase in the generating capacity of Millstone-3. The Richmond, Va.–based utility had applied for the power uprate last November, requesting an increase of approximately 1.6 percent.
NRC staff determined that Dominion could safely increase the reactor’s heat output, primarily through more accurate means of measuring feedwater flow, according to a November 18 press release. The NRC’s safety evaluation focused on several areas, including the nuclear steam supply systems, instrumentation and control systems, electrical systems, accident evaluations, radiological consequences, fire protection, operations and training, testing, and technical specification changes.

NASA and Idaho National Laboratory have just opened a competitive solicitation for U.S. nuclear and space industry leaders to develop innovative technologies for a fission surface power system that could be deployed on the surface of the moon by the end of the decade. Battelle Energy Alliance, the managing and operating contractor for INL, issued a request for proposals and announced the news on November 19. Proposals are due February 17.

Westinghouse Electric Company and Energoatom, Ukraine’s state-owned nuclear utility, signed a contract in Kyiv yesterday outlining the details of an agreement to bring the Westinghouse AP1000 reactor to Ukraine’s Khmelnitsky nuclear power plant.
According to a Westinghouse press release, the contract initiates engineering and procurement of long-lead items for the reactor.
Signing the contract were Patrick Fragman, president and chief executive officer of Westinghouse, and Petro Kotin, Energoatom’s acting president. U.S. charge d’affaires to Ukraine, Kristina Kvien, and Ukraine energy minister Herman Halushchenko also attended the event.

The license for Pacific Gas & Electric Company’s Humboldt Bay Unit 3 nuclear power plant near Eureka, Calif., has been terminated by the Nuclear Regulatory Commission, and the site has been released for unrestricted use. A 65-MWe boiling water reactor plant, Humboldt Bay-3 operated commercially from 1963 to 1976.

ANS sponsored 10 young nuclear professionals from the Young Generation Network, a branch of the U.K.’s Nuclear Institute, to attend COP26, the 2021 United Nations climate change conference, held in Glasgow, Scotland, where they helped deliver what was “by all accounts nuclear’s best representation at the COP ever,” according to George Burnett, one of four U.K.-based attendees sponsored by ANS.

By using a combination of physics-based modeling and advanced simulations, Texas A&M University researchers say they have found the key underlying factors that cause radiation damage to nuclear reactors, which could provide insight into designing more radiation-tolerant, high-performance materials.
