Nuclear News

On the eve of the 80th anniversary of the first controlled nuclear chain reaction, Nuclear Newswire is back with the second of three prepared #ThrowbackThursday posts of CP-1 coverage from past issues of Nuclear News.

On November 17, we surveyed the events of 1942 leading up to the construction of Chicago Pile-1, an assemblage of graphite bricks and uranium “pseudospheres” used to achieve and control a self-sustaining fission reaction on December 2, 1942, inside a squash court at the University of Chicago’s Stagg Field.

Today we’ll pick up where we left off, as construction of CP-1 began on November 16, 1942.

Aecon-Wachs, the U.S. division of Aecon Nuclear, has been tapped to support the Department of Energy’s goal of repurposing the unfinished Mixed Oxide Fuel Fabrication Facility at the Savannah River Site (SRS) in South Carolina. Known as Building 226-F, the facility is being transitioned into the Savannah River Plutonium Processing Facility (SRPPF) to produce plutonium pits for the nation’s stockpile of nuclear weapons.

Finnish energy companies Fortum and Helen Oy are initiating a study to explore collaboration on nuclear power projects, with particular emphasis on small modular reactors, the firms jointly announced last week, adding the caveat that “any future decisions on cooperation and investments will be made at a later stage.”

During a recent weeklong trip to Southeast Asia aimed at bolstering U.S. economic and security ties in the region, Vice President Kamala Harris announced the launch of nuclear energy partnerships with Thailand and the Philippines.

Currently, neither country enjoys the benefits of nuclear power. Both rely primarily on some mix of petroleum, natural gas, and coal for their energy needs.

Regardless of the specific field you work in or how your daily tasks are performed, digital technology does not go unnoticed, and the environmental remediation field is no exception. Digital technology can be defined as electronic tools, services, or devices that create, store, transmit, and manage data. As technology evolves, so do the ways in which it can be incorporated into remediation activities.

Adequate incorporation of these technologies can greatly improve both workflow and productivity while enhancing the quality and maintaining the integrity of data. My team and I have been able to connect radiological instruments to computers wirelessly, collect millions of radiological measurements, track the approximate location of these measurements, save measurements automatically in a database, and access them at will.

Westinghouse Electric Company and Finnish energy company Fortum have jointly announced the signing of a long-term partnership to develop, license, and supply VVER-440 fuel to Finland’s two-unit Loviisa nuclear power plant.

Experimentation on the world’s first molten salt reactor to potentially power aircraft was already underway in November 1954, being carried out by the U.S. Air Force. Oak Ridge National Laboratory was the scene for the power-dense, high-temperature reactor experiment known as the Aircraft Reactor Experiment (ARE).

The scale and duration of a national campaign to transport spent nuclear fuel (SNF) from commercial nuclear power plants around the United States would be unprecedented. A meticulous level of planning that considers many elements is needed to inspire public confidence and support.

Hunt

U.K. chancellor of the exchequer Jeremy Hunt last week assuaged any concerns that Britain’s nuclear energy advocates might have been harboring regarding the new government’s support for the proposed Sizewell C plant. (The United Kingdom is on its third prime minister since July, when Boris Johnson’s government granted EDF Energy its long-awaited development consent order for the new nuclear build project.)

What he said: In his November 17 Autumn Statement, while noting the United Kingdom’s status as “a global leader in renewable energy,” Hunt added, “We need to go further, with a major acceleration of home-grown technologies like offshore wind, carbon capture, and storage, and, above all, nuclear. This will deliver new jobs, industries, and export opportunities and secure the clean, affordable energy we need to power our future economy and reach net zero."

Advanced reactors and small modular reactors with strikingly different coolants and sizes offer an array of different benefits, but when it comes to fuel cycle issues, including spent fuel and waste, they have a lot in common with conventional light water reactors. Two reports released within the last week—a National Academies of Sciences, Engineering, and Medicine (NASEM) consensus committee report two years in the making and a Department of Energy study released by Argonne National Laboratory—address the timely topic of advanced reactor fuel cycle issues. While the NASEM committee ventured to define research and infrastructure needs to support the entire nuclear power fuel cycle, inclusive of new technologies, for decades to come, the DOE report compares the front- and back-end fuel cycle metrics of three reactor designs (from NuScale Power, TerraPower, and X-energy) that have been selected for DOE cost-share–funded demonstrations within this decade. Together, these reports provide assurance that the fuel cycle needs of a fleet of new reactors can be met and point to near-term research and planning needs.

Pacific Gas & Electric’s two-unit Diablo Canyon plant—California’s lone operating nuclear power facility—has been deemed eligible for the initial round of funding from the Civil Nuclear Credit (CNC) Program, the Department of Energy announced yesterday.

The decision was welcomed by a nuclear community disappointed by last Friday’s news that the DOE had rejected Holtec International’s CNC application for the recently closed Palisades nuclear plant in Michigan, despite support for the effort from Gov. Gretchen Whitmer.

Nuclear energy is no longer on the fringes of the international climate conversation. At COP27, the United Nations climate change conference held in Sharm el-Sheikh, Egypt, from November 6 to 18, pronuclear advocates were everywhere—and they were talking to everyone. They populated the International Atomic Energy Agency’s #Atoms4Climate pavilion, the first-ever nuclear pavilion in the 27-year history of the negotiations. Echoing such strong representation, the final statement issued by the conference used language that included nuclear power.

Taking waste into outer space would require quite large vehicles, like the Saturn 5 rocket shown here carrying the Apollo 14 crew to the moon. A huge fireball forms underneath the rocket . . . hmm, would that be wise? (Source: NASA)

Nuclear waste disposal presents a frustrating problem far beyond its actual danger. No one has ever been harmed by commercial nuclear waste, and no one is likely to ever be harmed.

But we do have to find a final resting place for nuclear waste as it decays away back to the levels of the ore from which it came.

There are several types of nuclear waste: low-­level waste (LLW), intermediate-­level waste (ILW), transuranic waste (TRU; referring only to bomb waste without a lot of ­cesium-­137 or strontium-­90), high-­level waste (HLW; also only bomb waste), and spent nuclear fuel (SNF; from commercial power plants only). In the United States, TRU waste, HLW, and SNF require deep geologic disposal by law.

Canada’s Bruce Power, operator of the eight-unit Bruce nuclear plant in Kincardine, Ontario, has announced a “made-in-Ontario solution” to the net-zero challenges faced by industries: allowing new incremental nuclear output to be accredited for an avoided emissions benefit.

Consolidated Uranium plans to acquire Virginia Energy Resources, which owns Virginia Uranium and the Coles Hill Uranium Project, an undeveloped uranium deposit that sits under about 3,000 acres of land in south central Virginia. The state’s General Assembly has maintained a moratorium on uranium mining since 1982 that was upheld in the courts as recently as 2020, but Consolidated Uranium sees reason for “confidence that the moratorium on developing uranium projects in the state may ultimately be overcome,” and appears content to settle in for a wait.

The Biden-­Harris administration has committed to decarbonizing the power sector by 2035 and the economy by 2050, while creating good jobs and promoting equity. There’s no question that the lowest-­cost, most reliable grid of the future will require clean, firm baseload power to support intermittent renewable energy.

Nuclear is such a reliable source of firm, flexible baseload power for the grid. Energy mix optimization models show that as penetration of renewables (such as solar and wind) grows, required energy storage capacity also grows, leading to increasing cost competitiveness of dispatchable carbon-­free power sources (including low-­impact hydro, geothermal energy, carbon capture and storage, zero-­carbon fuels like hydrogen, and nuclear). Nuclear power is an essential component of America’s transition to a clean electric grid to maintain reliability, resiliency, and affordability.

U.S. special envoy for climate John Kerry and Ukraine’s minister of energy German Galushchenko have announced a two-to-three-year pilot project aimed at demonstrating the commercial-scale production of clean hydrogen and ammonia from small modular reactors in Ukraine using solid oxide electrolysis.

Consent-based siting has become one of the emergent priorities in nuclear energy, particularly for spent fuel storage and high-level waste (HLW) disposal.¹ Consent-based siting is based on broad public participation to address the needs and concerns of communities, aiming for equity and environmental justice. While there are some successful examples (Finland and Sweden above all), consent-based siting is not a straightforward process. Although Japan, for example, adopted consent-based siting for their HLW disposal over 20 years ago, it has not yet identified a community to host a repository. Environmental and safety concerns have been the biggest bottleneck for siting nuclear facilities. A recent proposal for the interim storage in Andrews, Texas, for instance, has been opposed by Gov. Greg Abbott and others.

The Pennsylvania House of Representatives this week adopted a resolution directing the Joint State Government Commission to conduct a “holistic” study on the benefits of nuclear energy and small modular reactors. (The JSGC, according to its website, serves as the Pennsylvania General Assembly’s primary research organization, providing the legislature with a readily available mechanism for conducting interdisciplinary studies.) The November 15 vote was unanimous, 197–0.

The Nuclear Regulatory Commission is seeking public comment on the scope of its supplemental environmental impact statement (SEIS) concerning Dominion Energy’s subsequent license renewal (SLR) application for North Anna-1 and -2, the agency announced earlier this week.
