BWX Technologies Inc. announced today that its Advanced Technologies subsidiary has signed a cooperation agreement with the state of Wyoming to evaluate locations and requirements for siting a potential new TRISO nuclear fuel fabrication facility in the state.

Industry leaders from around the globe met this month to discuss the talent development that will be necessary for the long-term success of the nuclear industry.

The International Conference on Nuclear Knowledge Management and Human Resources Development, hosted by the International Atomic Energy Agency, was held in Vienna earlier this month. Discussed there was the agency’s forecast for nuclear capacity to more than double—or hopefully triple—by 2050 and the requirement of more than four million professionals to support the industry.

Dominion Energy Virginia has issued a request for proposals from leading nuclear companies to study the feasibility of putting a small modular reactor at its North Anna nuclear power plant.

While the utility says it is not a commitment to build an SMR at the site, the RFP is “an important first step in evaluating the technology and the North Anna site to support Dominion Energy customers’ future energy needs consistent with the company’s most recent Integrated Resource Plan.”

One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has since been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that Unit 3 was back in service.

Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. local time on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

A new supercomputer named Bitterroot started operating in June at Idaho National Laboratory’s Collaborative Computing Center (C3) and is speeding up nuclear energy research by improving access to modeling and simulation tools. Bitterroot arrived at INL in March, and the announced July 15 that the supercomputer was open to users on June 18 after installation and an extensive program of testing.

Oceans link all the continents of the world, and fish don’t respect boundary lines. So it’s fitting that a global organization—the International Atomic Energy Agency—is helping nations detect and monitor both plastic pollution and biotoxins in marine algae that can lead to outbreaks of contaminated seafood.

Dozens gathered last week at a public hearing hosted by the Nuclear Regulatory Commission to get feedback on the proposal to restart the Palisades nuclear power plant in Michigan.

The NRC is beginning its environmental review of plans to repower Palisades after it was shut down in May 2022 and was headed for permanent decommissioning. If the restart is successful, this would be the first return to service of a shuttered U.S. nuclear plant.

The combined energy generation in the United States from solar and wind during the first half of the year was more than that of nuclear plants for the first time, according to data from energy think tank Ember.

Electricity generation from utility-scale solar and wind assets during the first half of 2024 was a record 401.4 terawatt-hours, compared with 390.5 TWh from nuclear reactors

While no development details have been released, Constellation is asking to rezone 658.8 acres of land it owns around the Byron nuclear plant in Illinois for possible long-term use.

Comprehensive analysis of 245 operational coal power plants in the United States by a team of researchers at the University of Michigan has scored each site’s advanced reactor hosting feasibility using a broad array of attributes, including socioeconomic factors, safety considerations, proximity to populations, existing nuclear facilities, and transportation networks. The results could help policymakers and utilities make decisions about deploying nuclear reactors at sites with existing transmission lines and a ready workforce.

Duke Energy Florida is considering long-term plans for new nuclear development on 5,000 acres it owns near Gainesville.

According to testimony filed in Duke’s three-year, $818 million rate hike request with the Florida Public Utilities Commission, “In the 2038–2048 timeframe, this would be an attractive site for [the] addition of a new zero-emitting load following resource . . . including the potential development of next generation nuclear [small modular reactor] technology.”

2024-2025 ANS President

The importance of an education was instilled in Lisa Marshall at a young age by her grandmother. Born in Trinidad, Marshall was raised by her grandparents after her parents emigrated to Canada in pursuit of their educational goals. “My grandmother, Winifred, saw education as the route to the next level,” Marshall said, adding that the family wasn’t even sure if her grandmother had finished elementary school. “She wanted more for us than she had, and she believed the best way to achieve that was through an education.”

When Marshall was young, Winifred walked with her on the road from their house to school every day and was there to greet her when the school day was done. When Marshall was older, she went home for lunch, which her grandmother prepared. “She was a stabilizing force in my life,” Marshall said. “She kept me safe and nourished me. She taught me to be independent. And she always stressed the education part.”

In college I started in physics, but in 1977, during my sophomore year, I decided to pick a more practical major: nuclear engineering. Like many young people, I wanted to make the world a better place.

During my junior year, the Three Mile Island accident occurred. Many of us in nuclear engineering wondered whether we had chosen the wrong major, but our professors assured us there was a future in nuclear power. It seemed at the time a common-sense solution to the predicted shortages of oil and gas, and it was far safer than coal. I stayed the course and ended up getting my bachelor’s and master’s degrees in nuclear engineering.

Fast burst reactors were the first fast-spectrum research reactors to reach criticality by using only prompt neutrons with high-enriched uranium as fuel, creating a pulse for microseconds. Among many achievements, fast burst reactors were the first research reactors to demonstrate the ability of thermal expansion to terminate a pulse and to show how this could aid in reactor safety. In addition, fast burst reactors were pivotal in early fission studies including critical mass determination, criticality safety, the study of prompt and delayed neutrons, and much more.

Here is a recap of industry happenings from the recent past:

ADVANCED REACTOR MARKETPLACE

Radiant purchases nuclear-grade graphite for its microreactor

Microreactor startup Radiant Industries and Amsted Graphite Materials, the largest American-­owned synthetic graphite producer, have reached an agreement to collaborate on reducing U.S. reliance on foreign sources of nuclear-grade graphite. The collaboration began with Radiant placing a purchase order with Amsted for its Kaleidos microreactor, a 1-MW high-temperature, gas-cooled portable microreactor that has a graphite core and uses TRISO fuel.

The Nuclear Regulatory Commission has posted an unclassified version of its annual report to Congress on the results of the agency’s security inspection activities in 2023.

The report covers the NRC’s security inspection program, including force-on-force exercises, for commercial nuclear power reactors and Category I fuel cycle facilities. It keeps Congress and the public informed of the NRC’s oversight of the protection of the nation’s civilian nuclear power infrastructure and strategic special nuclear material.

Because of its hardness and its hardiness in the face of high temperatures, silicon carbide has been used for industrial purposes for decades. It has proven its worth as a key component of tiny TRISO fuel particles. But SiC has a weakness—in its pure form it is too brittle for use in structural components, such as 12-foot-long light water reactor fuel cladding tubes.

In 1976 at the Hanford Site in Washington state, a 64-year-old chemical operations technician named Harold McCluskey was working on columns filled with special exchange resins in a glove box at the Plutonium Finishing Plant.

The European Commission has issued a positive opinion on the technical and nuclear safety aspects of the construction of Units 3 and 4 at Cernavoda nuclear power plant in Romania.

Under the Euratom Treaty, nuclear project developers are required to notify the EC of planned investments and to demonstrate compliance with the highest nuclear safety standards.

JT-60SA (Japan Torus-60 Super Advanced) is the world’s largest superconducting tokamak device. Its goal is the earlier realization of fusion energy (see Fig. 1). Fusion is the energy that powers the Sun, and just 1 gram of deuterium-tritium (D-T) fuel produces enormous energy—the equivalent of 8 tons of crude oil.

Last fall, the JT-60SA project announced an important milestone: the achievement of the tokamak’s first plasma. This article describes the objectives of the JT-60SA project, achievements in the operation campaign for the first plasma, and next steps.
