The Unit 3 reactor at Slovakia’s Mochovce nuclear power facility has completed the commissioning process, becoming a full-fledged member of the country’s nuclear fleet, plant owner Slovenské Elektrárne has announced.

Texas-based Vistra Corporation was hoping to get the go-ahead from the Federal Energy Regulatory Commission this month for its proposed acquisition of Energy Harbor’s nuclear assets, but on October 13, the agency issued an order extending its review of the deal (called “tolling the time” in bureaucratese) to April 11, 2024. Currently down one seat, the four-member FERC voted 3–1 for the time extension, with the lone dissent coming from commissioner James Danly.

Ultra Safe Nuclear (USNC) announced on October 17 that it had been awarded a contract by NASA to develop and mature space nuclear thermal propulsion (NTP) systems to advance the nation’s cislunar capabilities. Under the contract, USNC says it will manufacture and test proprietary fuel and simultaneously collaborate with its commercial partner, Blue Origin, to mature the design of an NTP engine optimized for near-term civil science and cislunar missions.

The Department of Energy announced $7 billion on October 13 to launch seven regional Clean Hydrogen Hubs (H2Hubs) across the country and accelerate the commercial-scale deployment of clean hydrogen. Two of the seven hubs will feature hydrogen production using electricity—and possibly steam—from nuclear power. The federal government’s multibillion-dollar investment will be matched and exceeded by more than $40 billion from the awardees, for a total investment in clean energy and job creation near $50 billion.

The Nuclear Regulatory Commission has docketed an application from Dominion Energy South Carolina for the subsequent license renewal (SLR) of the V. C. Summer plant’s Unit 1 reactor. The action was announced in Monday’s edition of the Federal Register.

Westinghouse has signed a contract with Rolls-Royce SMR to develop a fuel design for the British firm’s small modular reactor program, the companies announced last week.

The design work, to be undertaken in the United Kingdom and the United States, will include associated core components and will be based on an existing Westinghouse pressurized water reactor fuel assembly design.

International engineering, construction, and project-management company Bechtel, which is headquartered in Reston, Va., opened its newest office, the Engineering Execution Center, in Knoxville, Tenn. The office—the second Bechtel has opened stateside in the last few months—will provide engineering support for the company’s numerous mission-based projects, and it is the second new U.S. office opened by Bechtel in the past few months—the other being in Chandler, Arizona.

The Nuclear Regulatory Commission last week issued a preliminary “yellow” finding to Dominion Energy for failing to resolve a two-decade-long problem with cracks in the piping of the V. C. Summer plant’s emergency diesel generator (EDG) fuel oil system.

The Nuclear Regulatory Commission will hold its 2023 Workshop on Advanced Manufacturing Technologies for Nuclear Applications on October 24–26 as a hybrid meeting.

The North Carolina General Assembly has overridden Gov. Roy Cooper’s October 2 veto of S.B. 678—a measure aimed at incentivizing the development of nuclear power facilities in the state.

Researchers at Idaho National Laboratory have a new experimental tool to study nuclear fuel under simulated loss of coolant accident (LOCA) conditions in INL’s Transient Reactor Test (TREAT) Facility. A specialized experiment holder called a TWIST capsule holds a fuel sample surrounded by water, which can rapidly drain away during testing, simulating loss of coolant in a light water reactor environment.

The International Atomic Energy Agency has released the 2023 edition of its annual look at nuclear’s prospects in the coming decades—Energy, Electricity and Nuclear Power Estimates for the Period up to 2050—revising its global growth projections upward for a third consecutive year.

Following the February 2021 radiation release at the National Institute of Standards and Technology (NIST) resulting from a fuel failure in the 20-MWt NIST Center for Neutron Research (NCNR) research reactor, NIST investigated the root cause of the incident and developed corrective actions. The Nuclear Regulatory Commission’s probe of the incident found apparent violations and resulted in a confirmatory order issued in August 2022.

Standard Power, a provider of infrastructure as a service to advanced data processing companies, has chosen NuScale Power as the technology provider for its plans to develop two small modular reactor–powered facilities in Ohio and Pennsylvania to run nearby data centers, the Portland, Ore.-based SMR developer announced on October 3.

Maintenance can mean no more than keeping the status quo. But plant maintenance programs at U.S. nuclear power plants do that and then some. Even the programs are themselves maintained and improved—and so a long-lived nuclear fleet has improved with time. Read on.

Through its Minority Serving Institution Partnership Program (MSIPP) and Tribal Education Partnership Program (TEPP), the Department of Energy’s National Nuclear Security Administration has awarded five grants totaling $2.5 million to minority-serving institutions (MSIs) and tribal colleges and universities (TCUs).

Georgia Power, primary owner of the Vogtle nuclear plant, announced last Friday that it will pay $413 million to settle a lawsuit brought against it last year by plant co-owner Oglethorpe Power Corporation.

Holtec International has taken another step on the arduous stairway to Palisades resurrection, announcing last Friday that it has filed with the Nuclear Regulatory Commission to “formally begin the process of seeking federal reauthorization of power operations” at the Covert Township, Mich., facility.

Rafael Mariano Grossi, director general of the International Atomic Energy Agency, officially opened the IAEA Nuclear Security Training and Demonstration Centre during an October 3 ceremony at the agency’s Seibersdorf laboratories in Austria. Representatives of 45 countries and territories were in attendance.

Southern Company, TerraPower, and Core Power (a U.K.-based firm focused on developing nuclear technologies for the maritime sector) have commenced pumped-salt operations in the Integrated Effects Test (IET) facility, the Atlanta, Ga.-based utility announced Tuesday, marking another milestone in the development of TerraPower’s first-of-a-kind, Generation IV Molten Chloride Fast Reactor (MCFR).
