Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) research laboratory in Germany have investigated a microorganism capable of transforming water-soluble hexavalent uranium [U(VI)] to the less-mobile tetravalent uranium [U(IV)]. The researchers found that the sulfate-reducing bacterium Desulfosporosinus hippei, a relative of naturally occurring microorganisms present in clay rock and bentonite, showed a relatively fast removal of uranium from clay pore water.

Crane

Exelon announced that Chris Crane, the company’s former chief executive, passed away on Saturday in Chicago at the age of 65.

Crane served as the company’s president and CEO from 2012 until his retirement in December 2022. During his tenure, he steered the energy company through several transformational milestones, including the successful mergers with Constellation Energy in 2012 and Pepco Holdings in 2016, creating the largest utility business by customer count in the United States.

In 2022, with the spin-off of Constellation as the generation and retail side of energy business (with the largest U.S. nuclear fleet), Crane led the creation of a stand-alone transmission and delivery energy company.

A recent drone attack at Ukraine’s Zaporizhzhia nuclear power plant prompted an emergency meeting by the International Atomic Energy Agency Board of Governors, during which the agency again called for the immediate removal of Russian military and personnel from the site.

During a state visit to the White House by Japanese prime minister Fumio Kishida on April 10, the Department of Energy announced that U.S. and Japanese agencies had cooperated to remove all high-enriched uranium (HEU) from the Japan Materials Testing Reactor Critical Assembly (JMTRC) of the Japan Atomic Energy Agency (JAEA) two years ahead of schedule.

China’s second demonstration reactor—Fangchenggang Unit 4—connected to the grid on April 9, China General Nuclear Power Group has announced. Located in the autonomous region of Guangxi, the reactor achieved first criticality April 3.

The Nuclear Regulatory Commission will hold a public meeting on May 8 to discuss the license termination process for the retired nuclear-powered merchant ship, the NS Savannah. During the meeting, NRC staff will discuss the license termination process and receive public comments on the remaining cleanup activities described in the license termination plan for the historic ship, which may see a second life as a floating museum.

Huff

After serving two years as the Department of Energy’s assistant secretary for Nuclear Energy, Kathryn Huff will vacate that position on May 3 and return to teaching. Huff had started at the DOE in May 2021, serving for one year as the principal deputy assistant secretary for Nuclear Energy.

“Serving in this capacity has been an unparalleled privilege, and I’m immensely grateful for the opportunity to have worked alongside you--the dedicated and talented public servants in Nuclear Energy, in DOE, and across the Biden-Harris Administration,” Huff wrote in an email announcement to colleagues last week. “I chose this timing to enable the smoothest transition back to my professorship at the University of Illinois at Urbana-Champaign where my beloved research, students, husband, and dog await.”

Clean Core Thorium Energy (Clean Core) has announced that its ANEEL fuel is ready to begin irradiation testing and qualification at Idaho National Laboratory. The fuel, made of thorium and HALEU, was developed by Clean Core for use in pressurized heavy water reactors, including CANDU (Canadian deuterium-uranium) reactors. Irradiation of the fuel samples in INL’s Advanced Test Reactor (ATR) is set to begin this month.

Nuclear Regulatory Commission staff will host a public information meeting on Wednesday, April 17, to discuss plans for repowering the shuttered Palisades nuclear plant in Michigan.

TerraPower’s application to build its Natrium nuclear power plant near Kemmerer, Wyo., is available for public viewing on the Nuclear Regulatory Commission website.

Laser Photonics Corporation and Brokk Inc. have announced the forming of a technology partnership to bring laser cleaning and cutting technology to the nuclear disposal, decommissioning, mining, tunneling, construction, metal processing, and military industries.

The first unit at Akkuyu, Turkey’s first nuclear power plant, has begun the commissioning process. The goal is that the plant will begin supplying energy to the nation next year, according to Rosatom, Russia’s state atomic energy corporation.

Researchers at the Department of Energy’s Princeton Plasma Physics Laboratory are using a stellarator they designed and built using permanent rare-earth magnets and a 3D-printed shell to help test new fusion power concepts. MUSE—the first stellarator built at PPPL in 50 years—took one year to construct and generated its first plasma in February 2023. The work that went into its design has already inspired a stellarator power plant concept being developed by a commercial spin-off, Thea Energy.

Next-generation reactor company Oklo Inc. is teaming up with Diamondback Energy Inc. to bring Oklo’s Aurora Powerhouse units to the American Southwest.

The companies signed a nonbinding letter of intent (LOI) this week to collaborate on a 20-year power purchase agreement that would provide 50 MW of electricity per unit to Diamondback’s Permian Basin operations area. The agreement lays out options to renew and extend the agreement for an additional 20-year term, since the units are designed to operate for 40 years without needing to refuel. Diamondback is an independent oil and gas company headquartered in Texas.

Unit 2 of South Korea’s Shin-Hanul nuclear power plant entered commercial operation on April 5, Korea Hydro & Nuclear Power announced. It is the nation’s 26th operating reactor, which continues the upward nuclear trend as South Korea reverses a previous phase-out plan for nuclear.

Energy secretary Jennifer Granholm submitted a Department of Energy report to the U.S. Congress on April 8 detailing the state of research reactors at U.S. universities and the potential need to upgrade or build additional reactors, including advanced nuclear reactors and test facilities.

To help expand access to clean nuclear energy, the Department of Energy announced it has awarded more than $19.1 million to support nuclear energy research and development, university nuclear infrastructure, and undergraduate and graduate education.

U.S.-based reactor company X-energy has partnered with Canadian power producer TransAlta Corp. to study the feasibility of deploying an advanced small modular reactor at a fossil fuel power plant site in Alberta.

Once used for applications in medicine, industry, and research, many countries now have legacy radium-226 sources, according to the International Atomic Energy Agency. With the support of the IAEA’s technical cooperation program, these disused sealed radioactive sources are being recovered, and countries are improving national capacities for their long-term management, including their potential reuse and recycling.

A new study by the Government Accountability Office researched potential impacts of climate change–related hazards on the U.S. nuclear fleet and found clear risks. In the report, which was released to the public last week, the GAO recommends that the Nuclear Regulatory Commission address these possible threats during the licensing process.
