At the University of Rhode Island, I initially enrolled as a candidate for an accelerated track to earn bachelor’s and master’s degrees in mechanical engineering, with a minor in nuclear engineering. My objective was to concentrate on reactor power design and join efforts to make nuclear energy safer, more efficient, and less stigmatized.

My plans changed after I attended a guest presentation on high-performance nuclear thermal propulsion (HP-NTP) led by Michael Houts, manager of NASA Nuclear Research at Marshall Space Flight Center. He posted his email address on one of the last slides, so I took a chance and contacted him about potential research opportunities and thesis work. As it turned out, that one little email ultimately led to four NASA-sponsored design projects at URI—two are complete, and two are in progress—as well as my thesis. My research has been on HP-NTP, specifically the centrifugal nuclear thermal rocket (CNTR) design. In that design, liquid uranium is heated to extremely high temperatures in a cylinder that is rotated between 5,000 and 7,000 revolutions per minute as liquid hydrogen passes through the center of the cylinder, where it is heated and expanded, exiting as a propellant while the liquid uranium is retained by centrifugal force.

The United Kingdom’s nuclear regulators—the Office for Nuclear Regulation (ONR), the Environment Agency, and Natural Resources Wales (NRW)—have announced the completion of step one of their generic design assessment (GDA) for Rolls-Royce SMR’s 470-MWe small modular reactor design and the start of step two, which is expected to last 16 months.

Canada’s Bruce Power, operator of Ontario’s eight-unit Bruce nuclear power plant, has announced the issuance of C$600 million (about $446.3 million) in green bonds in support of the company’s net-zero-by-2027 goal. (Investopedia defines green bonds as fixed-income instruments specifically earmarked to raise money for environmentally friendly projects.)

Capito

Sens. Shelley Moore Capito (R., W.Va.), Tom Carper (D., Del.), and Sheldon Whitehouse (D., R.I.) have introduced S. 1111—the Accelerating Deployment of Versatile, Advanced Nuclear for Clean Energy (ADVANCE) Act.

Unveiled in the Senate on March 30, the legislation is cosponsored by a bipartisan septet of lawmakers: John Barrasso (R., Wyo.), Cory Booker (D., N.J.), Mike Crapo (R., Idaho), Lindsey Graham (R., S.C.), Martin Heinrich (D., N.M.), Mark Kelly (D., Ariz.), and Jim Risch (R., Idaho).

The Department of Energy reported on March 30 that the Savannah River Site’s H Canyon facility recently initiated actions to recycle a small amount of used high-enriched uranium (HEU). SRS is a 310-square-mile DOE site in South Carolina.

The HEU, which is currently stored at the site’s H Area, will be downblended in a few years into high-assay low-enriched uranium (HALEU), which will help to provide fuel for advanced nuclear reactors in the United States.

The DOE has a brief video available with graphic information about HALEU.

Unit 3 at the Vogtle nuclear power plant has been successfully synchronized and connected to the electric grid, Georgia Power announced on April 1. The unit—one of two Westinghouse-supplied AP1000s at the Waynesboro, Ga., plant’s nuclear expansion site—becomes the first new U.S. power reactor to start up in seven years.

In a 39–13 bipartisan vote on March 30, the Illinois Senate passed legislation that would end the state’s prohibition on nuclear power plant construction—a ban that has been on the books since 1987.

Westinghouse has signed an agreement with ČEZ, owner and operator of the Czech Republic’s nuclear power plants, to supply VVER-440 fuel assemblies to the Dukovany facility, the American firm announced March 29. Fuel deliveries will commence in 2024, replacing Russia’s TVEL fuel, with an anticipated term of seven years. One of the Czech Republic’s two nuclear power plants, Dukovany houses four Russian-supplied VVER-440/V213 reactors.

The United States and Canadian nuclear industries used to be an example of how two independent teams of engineers facing an identical problem—making electricity from uranium—could come up with completely different answers. In the 1950s, Canada began designing a reactor with tubes, heavy water, and natural uranium, while in the U.S. it was big pots of light water and enriched uranium.

But 80 years later, there is a remarkable convergence. The North American push for a new generation of nuclear reactors, mostly small modular reactors (SMRs), is becoming binational, with U.S. and Canadian companies seeking markets and regulatory certification on both sides of the border and in many cases sourcing key components in the other country.

Fortum—operator of Finland’s two-unit Loviisa nuclear power plant—has signed a memorandum of understanding with Finnish stainless steel producer Outokumpu to explore decarbonizing the latter’s manufacturing operations with the help of emerging nuclear technologies, the companies announced on March 23.

The Department of Energy released Pathways to Commercial Liftoff: Advanced Nuclear earlier this month. It is one of the first in a series of reports on clean energy technologies and the private and public investments needed to overcome hurdles to full-scale deployment. The report makes a clear case for investment in nuclear power and challenges potential investors and operators to move beyond the current “wait and see” stalemate and generate “a committed orderbook . . . for 5–10 deployments of at least one reactor design by 2025.”

Nuclearelectrica has signed a memorandum of understanding with Emirates Nuclear Energy Corporation (ENEC) to provide both parties with an enabling framework for potential collaboration on the development and expansion of nuclear energy programs in Romania and the United Arab Emirates, as well as in Central and Eastern Europe.

Belgium-based engineering firm Tractebel and the Netherlands’ NRG Pallas have signed a memorandum of understanding to provide engineering services in support of new reactor construction at the Borssele nuclear power plant, located near the village of Borssele in the Dutch province of Zeeland.

A tiny 200-kWt reactor the Department of Energy says would be the first critical fast-spectrum circulating fuel reactor and the first fast-spectrum molten salt reactor (MSR) could be built and operated inside the Zero Power Physics Reactor (ZPPR) cell at Idaho National Laboratory’s Materials and Fuels Center (MFC). Details included in the Molten Chloride Reactor Experiment (MCRE) draft environmental assessment (EA)—released on March 16 for two weeks of public comment (later extended to four weeks, through April 14)—covered the potential environmental impacts associated with the development, construction, operation, and decommissioning of MCRE at INL, facilitated by the National Reactor Innovation Center (NRIC).

Declaring it a “great day for Virginia energy and American energy,” Gov. Glenn Youngkin on March 23 signed a number of bills to further his state’s all-of-the-above energy plan, including some measures sure to please nuclear energy advocates. Launched in October of last year, the Virginia plan touts nuclear among other energy sources and calls for deploying a commercial small modular reactor in southwest Virginia within the next 10 years.

The Department of Energy’s Office of Science published a notice in the March 27 Federal Register calling for input on technological approaches to a Fusion Prototypic Neutron Source (FPNS) for materials irradiation research under DOE-SC’s Fusion Energy Sciences program, as well as partnership models that could accelerate the construction and delivery of the facility. The request for information (RFI) calls for responses by May 11.

The challenges of climate change are bringing nuclear energy back into focus. Even in Germany, which decided on a general nuclear phaseout in 2011 as a response to the Fukushima disaster that year, nuclear energy is again being discussed as a bridging technology. Compared with fossil fuels, nuclear saves considerable greenhouse gases. However, for a holistic view of CO₂ emissions from power plants, the procurement, maintenance, and repair of plant components must also be considered. At the very least, the CO₂ emissions caused by the high costs of testing and maintaining a nuclear power plant can be reduced.

Startup company Last Energy has announced power purchase agreements for 34 units of its 20-MWe nuclear power plants with four industrial partners in Poland and the United Kingdom. In total, according to the company, the deals represent more than $18.9 billion in electricity sales.

The United States and Indonesia have announced a strategic partnership to help the latter nation develop its nuclear energy program, supporting its interest in deploying small modular reactors to meet energy security and climate goals.
