Revitalization of nuclear energy policy for green transformation in Japan

March 22, 2024, 2:59PMNuclear NewsAkira Yamaguchi

The revitalization of nuclear energy policy in Japan began on August 24, 2022, with Prime Minister Kishida’s address at the second Green Transformation (GX) Executive Meeting. He said, “It is urgent to resolve the present deadlock in energy policy; in order to overcome the current crisis in power supply and demand . . . we will take all possible measures to prepare for unforeseen circumstances. In particular, regarding nuclear power plants (NPPs), the government will take all possible measures to restart the suspended NPPs already licensed for operation.” Kishida emphasized that nuclear power is an indispensable decarbonized energy source for the advancement of the green transformation. The cabinet in February 2023 approved the Basic Policy for the Realization of GX (hereinafter referred to as the GX Basic Policy).

Congress votes on Price-Anderson Act extension

March 22, 2024, 1:39PMNuclear News

A minibus appropriations bill—the second produced this month by Congress—emerged from conference negotiations yesterday with language that would extend the Price-Anderson Act—legislation first enacted in 1954 that makes it possible for nuclear power producers to seek insurance from the private marketplace. Today the House of Representatives voted 286–134 to approve the minibus package of six fiscal year 2024 appropriations bills, and the Senate is expected to vote today, too. By extending the Price-Anderson Act—now set to expire in 2025—Congress can support the current U.S. power reactor fleet and pave the way for new reactor deployments.

Hanson

President Biden announced yesterday his intent to renominate Christopher T. Hanson to be a member and chair of the Nuclear Regulatory Commission.

Hanson was designated NRC chair by Biden in 2021 and was sworn in as a commissioner on June 8, 2020. He is filling the remainder of a five-year term ending on June 30, 2024.

Experience: Hanson has more than two decades of government and private-sector experience in nuclear energy. Prior to joining the NRC, he served as a staff member on the Senate Appropriations Committee, where he oversaw civilian and national security nuclear programs. Before working in the Senate, he was a senior advisor in the Department of Energy’s Office of Nuclear Energy. He also worked in the DOE’s Office of the Chief Financial Officer, where he oversaw nuclear and environmental cleanup programs and managed the department’s relationship with congressional appropriations committees.

Nuclear moments

Grace Stanke

I just spent 13 months as Miss America 2023 advocating for nuclear energy. Throughout those 13 months, I traveled approximately 280,000 miles to 23 states and eight countries. I have now seen eight different power plants (seven in the United States and one in Japan). I visited radiological isotope production facilities, reprocessing facility construction sites, research facilities, and more. My work extended to visits at schools, trips to talk with state and national legislators, and stops at varying professional groups looking to learn more about nuclear science. It certainly was an interesting year, and one that I could not have foreseen.

Experiences: One thing that this year has made me appreciate about the nuclear industry: No matter what facility, and no matter what country you are in, there is always a plan. I never thought I would be so giddy to walk into a power plant and sit down for a pre-job brief, but honestly, I love them now. The desire to be prepared and have a plan is not so present in most other industries!

EnergySolutions buys Cabrera; eyes work in Asia

March 21, 2024, 7:01AMNuclear News

Utah-based waste management company EnergySolutions is expanding its operations in the United States and Asia, announcing last week that it had acquired Cabrera Services, a U.S. provider of environmental and radiological remediation services. It also signed a memorandum of understanding with Germany’s GNS Gesellschaft für Nuklear-Service to provide services to the Asian nuclear market.

Plasma oscillation has fusion energy implications

March 20, 2024, 3:00PMANS Nuclear Cafe

Researchers from the University of Rochester in New York and the University of California–San Diego have published a paper in Physical Review Letters describing a previously unknown class of plasma oscillations. In “Space-Time Structured Plasma Waves,” the researchers “demonstrate that electrostatic wave packets structured with space-time correlations can have properties that are independent of the plasma conditions,” such as “density, temperature, ionization state, or details of the distribution functions.” This finding is technologically relevant, the authors note, because “electrostatic waves play a critical role in nearly every branch of plasma physics from fusion to advanced accelerators, to astro, solar, and ionospheric physics.”

ADVANCED REACTOR MARKETPLACE

PPPL awards contract for fusion development

The Department of Energy’s Princeton Plasma Physics Laboratory has awarded an engineering support services contract for the development of fusion energy to a consortium of business partners led by AtkinsRéalis that includes Jacobs Technology and Longenecker and Associates. The contract has a base period of three years with two optional years and a ceiling value of $50 million. Services to be provided under the agreement include design of future upgrades for the National Spherical Torus Experiment–Upgrade (NSTX-U, the main fusion experiment at PPPL); design and fabrication of plasma diagnostic and heating subsystems for ITER (the international fusion facility being constructed in France); conceptual design of electricity-generating fusion plants; and development of physics and technology advances for improving the economics of fusion plants. Another partner that will support this contract is the United Kingdom Atomic Energy Authority, for which AtkinsRéalis has been working on stage 1 of the Spherical Tokamak for Energy Production (STEP) program.

In March 1949—75 years ago this month—the 25-kilowatt reactor known as Clementine reached full power. As an experimental reactor, it had a rather long and successful run. It was the world’s first fast neutron (high-energy) reactor and operated from initial criticality in 1946 to final shutdown in 1952.

The owners of the Diablo Canyon nuclear power plant plan to dredge a massive buildup of shoaled sediment from its seawater intake cove.

Pacific Gas and Electric spokesperson Suzanne Hosn said, “The dredging project in the Diablo Canyon marina will remove approximately 70,000 cubic yards of sediment to prevent circumstances that could impact the power plant’s cooling system. Dredging will take place for the first time since operations began because of a rapid increase in sediment.”
