Constellation Energy, owner and operator of the nation’s largest reactor fleet, will ask the Nuclear Regulatory Commission to extend the operating licenses of the Clinton and Dresden reactors by 20 years, the company announced Monday, adding that it expects to file license applications with the agency in 2024.

Collecting belt buckles from nearly every nuclear power plant in the U.S. wasn’t the goal for Don Hildebrant when he obtained his first one. Over time, it just turned out that way.

One day years ago, Hildebrant came across a buckle from the nuclear plant where he worked, and it seemed before he knew it, he had collected more than 250 of them—some from plants that were never even completed. “When you look at the collection, you will see an interesting story of where nuclear power has been, and how far it has come,” he said.

Pacific Gas and Electric Company filed a letter with the Nuclear Regulatory Commission yesterday, officially requesting that the agency resume its review of the utility’s license renewal application for Diablo Canyon Units 1 and 2.

Computer-Guided Work

When it comes to computer-guided navigation, we look to our GPS app for seamless guidance. It provides granular, step-by-step directions while it tracks our position and progress towards our destination. It superimposes relevant information such as the location of restaurants and the lowest price gas stations on route. One of these days, it will even read us the menu of a selected restaurant on our path while placing an order as we drive towards it.

An international collaboration between Bruce Power, Isogen (a Kinectrics and Framatome company), and ITM Isotope Technologies Munich SE (ITM) announced they have begun commercial production of lutetium-177 using Unit 7 of the Bruce nuclear power plant in Kincardine, Ontario. According to the companies, this marks the first time a commercial power reactor has been used to commercially produce short-lived medical radioisotopes.

The United States and Japan have announced Winning an Edge Through Cooperation in Advanced Nuclear (WECAN)—a new agreement aimed at supporting the deployment of small modular reactors and other advanced reactor technologies in partner countries.

Managing plant source term for refueling outage cleanup and full power service can be controlled with the aid of specially macroporous resins. These ion exchange resins are often a cost-effective media for containing impurities in nuclear coolant, minimizing the release of contaminants and ionic leakage, all while encountering impact from oxidative chemistry and radiation. Macroporous resins continue to meet increased expectations in the industry and are considered among the best-accepted practices for nuclear plant source term minimization in standalone and layered polishing vessels.

The Nuclear Regulatory Commission is increasing its social media presence with its new Instagram page, the agency announced. The "nrcgov” account on the popular site will post photos, short videos, and graphics to add “a more creative approach to information regarding the NRC’s mission, with a focus on the skilled and diverse employees who carry it out.”

Magwood

As part of the Purdue University–Duke Energy Understanding Tomorrow’s Nuclear Energy lecture series, William D. Magwood IV, director general of the OECD Nuclear Energy Agency (NEA), delivered a lecture on October 24 at the Purdue Memorial Union Ballrooms. “The 21st Century Nuclear Resurgence: Opportunities and Challenges” was the third lecture in the series, which focuses on small modular reactors.

Magwood reviewed the factors that have led to the current increased interest in nuclear energy around the world, the serious challenges that must be quickly and adequately addressed, and the structural barriers that require new thinking by regulators and policymakers. He also commented on the ongoing Purdue-Duke study of the feasibility of using SMRs to meet the West Lafayette campus’s long-term energy needs.

Morawiecki

Poland has chosen Westinghouse Electric Company to supply the reactors for its initial nuclear power plant, as the Central European nation seeks to lessen its dependence on domestic coal and Russian imports for its energy supply. On Friday, Polish prime minister Mateusz Morawiecki announced the decision on Twitter, confirming last week’s reports that Westinghouse’s AP1000 technology was the government’s likely choice.

“A strong [Polish-American] alliance guarantees the success of our joint initiatives,” Morawiecki tweeted. “After talks with [vice president Kamala Harris and energy secretary Jennifer Granholm], we confirm our nuclear energy project will use the reliable, safe technology of [Westinghouse].”

Competing with the American firm for the job were Électricité de France and Korea Hydro & Nuclear Power. In October 2021, EDF submitted an offer to build four to six EPRs in Poland, while KHNP offered in April of this year to construct six APR1400 units.

NuScale Power and Prodigy Clean Energy announced on October 26 that they have developed a conceptual design for a transportable, marine-based small modular reactor. The companies plan to present the design to utilities, regulators, and shipyard manufacturers. Prodigy, a Canadian company “specializing in the development of transportable nuclear power plants,” and NuScale signed a memorandum of understanding in 2018 agreeing to pursue the development of an SMR marine facility.

The Department of Energy’s Office of Environmental Management (EM) announced that construction of Hanford’s K East Reactor cocoon has been completed ahead of schedule and under budget. Cocooning of K East—enclosing it in a protective steel structure while the reactor’s radioactivity naturally decays—was one of EM’s key construction priorities for 2022.

The trouble with tritium is there is no trouble with tritium.

At any level outside the laboratory, either experimental or manufacturing, tritium is harmless. Every year, we routinely release millions of gallons of slightly tritiated water to the ocean, large lakes, and large rivers from almost every commercial nuclear reactor in the world, and have done so for decades, all in accordance with globally accepted nuclear safety standards. And no adverse effects on the environment or humans have ever been seen.

Any method that can enhance safety, reduce risk, and lower costs is worth a second look. When that method proves it has the potential to optimize aging management at any nuclear power plant, it’s time to spread the word.

In 2019, a small team focused on selective leaching began looking for a way to use risk insights to optimize the implementation of deterministic aging management programs (AMPs). What they started soon grew into a large team effort by Constellation, Ameren, the Electric Power Research Institute (EPRI), and the Nuclear Energy Institute (NEI), along with contractors Enercon and Jensen Hughes, to develop a generic framework and then test it in two very different pilot applications.

Unit 3 at Slovakia’s Mochovce nuclear power plant achieved initial criticality on October 22, plant owner Slovenské Elektrárne has announced.

The utility started the reactor’s first fuel load September 9—after receiving in August a final authorization for commissioning from the Slovak Nuclear Regulatory Authority—and completed the process three days later.

The Department of Energy announced $150 million in Inflation Reduction Act funding on October 25 for infrastructure improvements at Idaho National Laboratory. According to the DOE, the funding will support nearly a dozen projects at INL’s Advanced Test Reactor (ATR) and Materials Fuels Complex (MFC), both of which have operated for more than 50 years. The investments in existing infrastructure assets mean support for nuclear energy research and development, including fuel testing, bolstering the near-term supply of high-assay low-enriched uranium (HALEU), and reactor demonstrations.

Nuclear technology firm TerraPower and utility partner PacifiCorp have launched a study to evaluate the feasibility of deploying up to five additional Natrium reactor and integrated energy storage systems in the utility’s service territory by 2035, the companies announced yesterday. (PacifiCorp’s business units—Pacific Power and Rocky Mountain Power—serve customers in California, Oregon, and Washington, and in Idaho, Utah, and Wyoming, respectively.)

In the summer of 2019, three students from the University of South Carolina–Aiken (USCA) had an idea to digitize the isotope. Wei Zheng, Drake Jones, and Joseph Taylor set out to design an app that would be an interactive one-stop shop for information about any isotope—number of protons and neutrons, whether it is stable or radioactive, its natural abundance on earth, and even its uses. From these ideas, the Interactive Isotopes App began to take shape.

The app’s launch was disrupted by the COVID-19 pandemic; although it was complete after three years of work and development, the creators sat on it. On October 12, the app at long last went live on the ANS website.

Framatome has completed the second 18-month cycle of its GAIA Protect Enhanced Accident Tolerant Fuel (EATF) technology at Vogtle’s Unit 2 in Waynesboro, Ga. Inspections afterward revealed that the full-length chromium-coated fuel rods maintained their original characteristics, while the chromia-enhanced pellets operated as designed during 36 months of reactor operation.

Tokamak Energy on October 26 announced plans to construct a high field spherical tokamak using high-temperature superconducting (HTS) magnets. Dubbed the ST80-HTS, the machine would demonstrate multiple technologies required to achieve commercial fusion energy, the company says. Tokamak Energy plans to complete the ST80-HTS in 2026 to demonstrate spherical tokamak operations and inform the design of its successor, a fusion pilot plant called ST-E1 that the company says could deliver electricity into the grid in the early 2030s and produce up to 200 MWe.

Temperature milestone: Earlier this year, the company’s ST40 spherical tokamak reached the commercial fusion energy plasma temperature threshold of 100 million °C with what was reported as the highest triple product (an industry measure of plasma density, temperature, and confinement) of any private fusion energy company. The ST40 achieved those results with a plasma volume of less than one cubic meter, which is 15 times less volume than any other tokamak that has achieved the same threshold.
