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.”

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.

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.

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.

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.

State regulators will study the economic and technical feasibility of adding advanced nuclear technology in Florida.

The directive was included in a sweeping energy bill, House Bill 1645, passed by the Florida Legislature and signed into law by Gov. Ron DeSantis. The Florida Public Service Commission must issue a report to the governor and legislative leaders by April 1, 2025, with findings and recommendations to support new nuclear in the state—specifically including military bases.

Aalo reported last week that it has submitted a regulatory engagement plan to the Nuclear Regulatory Commission in “a huge step forward in getting regulatory approval for our Aalo-1 reactor.”

Peters

Mark Peters will become president and chief executive officer of MITRE, effective September 3, 2024. He will succeed Jason Providakes, who previously announced his intention to retire after 37 years with the not-for-profit research and development company, including seven years as president and CEO.

Peters is a recognized expert in nuclear fuel cycle technologies, nuclear waste management, and national security, with more than 25 years of leadership and scientific discovery for federally funded R&D centers (FFRDCs). He currently serves as executive vice president, laboratory management and operations, at Battelle Memorial Institute, which, with other strategic partners, operates eight FFRDCs for the federal government, with responsibility for governance and oversight of the Department of Energy and Department of Homeland Security national laboratories.

American Electric Power and Exelon are seeking a hearing with the Federal Energy Regulatory Commission about a proposed data center project linked to Talen’s Susquehanna nuclear plant in Pennsylvania.

While commissioning began earlier this year at Turkey’s first nuclear plant, new reports say the project is delayed by sanctions against Russia due to its military invasion of Ukraine.

Constellation Energy is in talks with the governor’s office and state legislators about funding to restart a unit at Three Mile Island nuclear plant, Reuters has reported. The ongoing talks have been described as “beyond preliminary” by two sources.

An external radiation monitoring station was taken out by shelling and fire near the Zaporizhzhia nuclear plant in Ukraine the last week of June.

This brings the total to four of the plant’s 14 radiation monitoring sites that are out of commission, further reducing the effectiveness of its off-site capability to detect and measure any radioactive release during an emergency, said IAEA director general Rafael Mariano Grossi.
