The June 2017 special report on the ANS Nuclear Grand Challenges (available online at ans.org/challenges/) identified low-dose radiation as a crucial focus area for ANS. Specifically, the challenge is to “Establish the scientific basis for modern low-dose radiation regulation.” This is particularly difficult given the long review cycles associated with International Commission on Radiological Protection (ICRP) and National Council on Radiation Protection and Measurements (NCRP) recommendations. Additionally, while the Environmental Protection Agency is tasked with issuing guidance on radiation exposure standards in the United States, responsibility for implementing and enforcing radiation protection regulations is distributed throughout the federal government. Finally, while it is accepted that tissue reactions (previously called deterministic or nonstochastic effects) exhibit a dose threshold, there is still substantial scientific debate over the shape of the dose response at low doses for stochastic effects, such as cancer. Despite these hurdles, substantial progress has been made over the past five years on the low-dose radiation grand challenge.

The House Science, Space, and Technology Subcommittee on Energy held a hearing last week to evaluate the Department of Energy’s approach to research and development on new strategies and technologies to support the nuclear waste cleanup mission of its Office of Environmental Management (EM).

In a much-anticipated vote yesterday, EU lawmakers voted down a resolution objecting to the European Commission’s proposal to add nuclear energy and natural gas to the list of green technologies covered by the EU taxonomy—the classification system used by the European Union to steer private investment toward environmentally sustainable economic projects.

The vote, held during the European Parliament’s July 4–7 plenary session, was 328 opposed to the resolution, 278 in favor, and 33 abstaining. An absolute majority—353 members—was required for the resolution to be passed and the proposal vetoed.

The Department of Energy yesterday announced that it has amended its Civil Nuclear Credit (CNC) Program guidance for the currently open award cycle and extended the deadline for credit applications from July 5 to September 6. The DOE was instructed to establish the $6 billion program by the Infrastructure Investment and Jobs Act, signed into law by President Biden last November.

The House Appropriations Committee has delivered to the full House the fiscal year 2023 Energy and Water Development bill in a 32–24 vote, along with a notable amendment concerning, among other things, Diablo Canyon, high-assay low-enriched uranium (HALEU), and thorium molten salt reactors. The amendment received a thumbs-up at the committee’s June 28 markup session via voice vote.

The Nuclear Regulatory Commission has published in the Federal Register a final rule amending the licensing, inspection, special projects, and annual fees it will charge applicants and licensees for fiscal year 2022. A proposed rule on the matter was published for public comment February 23.

On the road to achieving net-zero by midcentury, low- or no-carbon energy sources that slash carbon dioxide emissions are critical weapons. Nevertheless, the role of nuclear energy—the single largest source of carbon-free electricity—remains uncertain.

Nuclear energy, which provides 20 percent of the electricity in the United States, has been a constant, reliable, carbon-free source for nearly 50 years. But our fleet of nuclear reactors is aging, with more than half of the 92 operating reactors across 29 states at or over 40 years old—the length of the original operating licenses issued to the power plants. While some reactors have been retired prematurely, there are two options for those that remain: retire them or renew their license.

Legislation known as the Thorium Energy Security Act, introduced in Congress last month by U.S. Sen. Tommy Tuberville (R., Ala.), would put a halt to the destruction of U.S. stockpiles of uranium-233 and instead would foster its integration into the development of thorium molten salt–cooled reactors, Newsweek reported last week. The act has been referred to the Senate Committee on Energy and Natural Resources.

The Department of Energy has issued a proposed guidance amendment for its $6 billion Civil Nuclear Credit (CNC) Program in response to a letter last month from California Gov. Gavin Newsom’s administration suggesting “a few minor adjustments” to the program’s guidance to address “the unique circumstances” of the Diablo Canyon nuclear plant. (Previously a supporter of the premature 2025 closure of the Avila Beach, Calif., facility, Newsom told the Los Angeles Times in late April that his office would look into using the CNC Program to keep the plant in operation beyond its scheduled closure date, citing climate change and the threat of power shortages in the state.)

Feinstein

Although previously a supporter of Diablo Canyon’s early closure, California Sen. Dianne Feinstein took to the pages of the Sacramento Bee yesterday to endorse life extension for the state’s sole operating nuclear power plant.

Citing projected electricity shortfalls in California due to the effects of climate change, Feinstein writes that “Pacific Gas and Electric Company should reconsider its decision to close Diablo Canyon by 2025. The utility should get the plant relicensed instead, retiring it once the state can replace its production with clean sources.”

The senator continues: “I remain concerned about the lack of long-term storage for spent nuclear fuel and am working to develop better solutions. But at this point, keeping Diablo Canyon open and producing carbon-free energy is more important.”

This past April, California Gov. Gavin Newsom expressed interest in using the federal government’s new $6 billion Civil Nuclear Credit (CNC) Program to keep Pacific Gas and Electric Company’s Diablo Canyon nuclear plant in operation beyond its scheduled 2025 closure date.

That interest would appear not to have waned, as Newsom’s cabinet secretary, Ana Matosantos, recently sent a three-page letter to energy secretary Jennifer Granholm requesting some alterations to the program’s language to ensure that Diablo Canyon would be eligible to participate.

The full letter, detailing the requested changes, is available here.

Montana is among the states that have already expressed interest in small modular reactor technology as a possible means of decarbonizing their energy sectors.

Just last year, Montana Gov. Greg Gianforte signed into law H.B. 273, transferring the power to authorize construction of nuclear power facilities in the state from the public (via referendum) to the legislature.

Pollster Scott Rasmussen reports that 53 percent of American voters support the construction of new nuclear power plants in the United States, while 31 percent oppose new plants. He further reports that 21 percent strongly favor and 14 percent strongly oppose new nuclear facilities.

The International Atomic Energy Agency has delivered its report on Uganda’s infrastructure development for a nuclear power program to that country’s government, according to ESI Africa. The online power and energy journal states that the energy demand in the country (population: 43 million) has ballooned in recent years as the nation’s economy has expanded.

A team from the Department of Energy’s Office of Nuclear Energy joined ANS Executive Director/Chief Executive Officer Craig Piercy on April 27 for an ANS members–only online event to discuss the Biden administration’s fiscal year 2023 NE budget proposal. The proposed total for the office, $1.675 billion, is more than a $20 million increase from the FY 2022 enacted level of $1.654 billion.

The deadline for applications to the ANS's Glenn T. Seaborg Congressional Science and Engineering Fellowship has been extended. All ANS members are invited to apply to help the Society fulfill its strategic goal of informing nuclear public policy.

All applications and supporting documents are now due by 11:59 p.m. (EDT) on Monday, May 23.

ANS has recently published a new standard:

ANSI/ANS-2.21-2022, Criteria for Assessing Atmospheric Effects on the Ultimate Heat Sink (revision of ANSI/ANS-2.21-2012 [R2016]).

The standard is available for purchase from the ANS Store.

The administration of Colorado Gov. Jared Polis “appears uninterested in nuclear energy, bucking a growing consensus that nuclear power is an essential component in eliminating carbon emissions,” writes Scott Weiser in a recent Denver Gazette article. Weiser notes that nuclear power is not part of the governor’s Greenhouse Gas Pollution Reduction Roadmap for 100 percent carbon-free energy by 2040.

Huff

The Senate has confirmed ANS member Kathryn Huff as the next assistant secretary for the Office of Nuclear Energy (NE) in the Department of Energy. The bipartisan vote, held earlier this afternoon, was 80–11.

President Biden selected Huff in January to fill the top spot at NE—a post that has been vacant since Rita Baranwal (also an ANS member) announced she was leaving the position on January 8, 2021.

Huff came to the DOE in May of last year to serve as principal deputy assistant secretary for nuclear energy, going on unpaid leave from her position as an associate professor in the Department of Nuclear, Plasma, and Radiological Engineering at the University of Illinois–Urbana-Champaign, where she led the Advanced Reactors and Fuel Cycles Research Group.

President Biden has announced his intention to nominate Annie Caputo and Bradley R. Crowell to fill the two vacant seats on the Nuclear Regulatory Commission.
