Bill would eliminate public hearing requirement in nuclear licensing

May 14, 2024, 9:30AMNuclear News

A bill being considered in the U.S. Senate seeks to remove the requirement for the Nuclear Regulatory Commission to hold a public hearing for every nuclear reactor application.

Current law requires public hearings to be held by the NRC toward the end the reactor license application process, in addition to the statutorily required environmental and safety reviews that provide public engagement opportunities for stakeholders and citizens.

The company is aiming to provide clean, reliable, affordable nuclear energy to customers across the artificial intelligence, data center, energy, defense, and industrial markets. Sam Altman, chairman of Oklo since 2015 and former chief executive of AltC, called the first day on the NYSE a milestone for the entire team.

How robust is HALEU from a nonproliferation perspective?

High-assay low-enriched uranium (HALEU) has emerged as a popular fuel choice for advanced small modular reactors due to its long power production periods before refueling. It is currently being pursued by TerraPower, X-energy, BWX Technologies, Kairos, Oklo, and other reactor companies. HALEU has a uranium-235 enrichment ranging from 5 percent to 20 percent, whereas traditional LWRs use low-enriched uranium fuel enriched up to 5 percent.

HALEU will provide power for longer durations, compared with traditional LWRs. But could it also provide an opportunity for more rapid proliferation, as is speculated in a 2023 National Academy of Sciences report on advanced nuclear reactors (nap.nationalacademies.org/catalog/26630/)?

If a nuclear proliferator conspires to divert fresh nuclear fuel for weapons production when it has not been used in a reactor, the effort required in separative work units (SWUs) to enrich U-235 from 5 percent to 90 percent and that required to enrich from 20 percent to 90 percent are both very small, compared with the effort required to enrich U-235 from its natural abundance to the initial 5 percent.

U.S. nuclear capacity factors: Ideal for data centers?

May 10, 2024, 3:00PMNuclear NewsSusan Gallier

Baseload nuclear generation doesn’t get the respect it deserves, if you ask nuclear operators. But the hyperscale data centers that process our digital lives—like the one right next to the Susquehanna plant in northeastern Pennsylvania—are pushing electricity demand up. Clean, reliable capacity now looks a lot more valuable.

Cecilia Payne-Gaposchkin: The woman who first grasped the elemental power of stars

When the U.S. Fusion Energy Outreach Team declared the second week of May as Fusion Energy Week, they were recognizing the May 10 birthday of Cecilia Payne-Gaposchkin—the British-born American astronomer who applied principles of quantum physics, chemistry, and astronomy to become the first to realize—at the age of 25—that stars and the universe itself are mostly composed of hydrogen and helium, and that the stars could be sorted by their spectra into groups that corresponded to the temperature of the stars.

The U.K. government this week announced a $245 million (£196 million) award to help Urenco build Europe’s first advanced reactor fuel manufacturing plant, which will be located in northwest England at the company’s Capenhurst site. Urenco, which is part-owned by the U.K. government, will cofund the project.

Proof of concept: The Molten Salt Reactor Experiment in Nuclear News

By late 1960, when the U.S. Atomic Energy Commission authorized plans to build a Molten Salt Reactor Experiment (MSRE) at Oak Ridge National Laboratory, the lab already had about 13 years of experimentation with molten salt reactors under its longest-serving lab director, Alvin Weinberg. The MSRE operated from 1965 to 1969, proving that molten salt reactors could operate reliably, and with alternatives to uranium-235 too.

Terrestrial Energy and Schneider Electric are teaming to deploy Terrestrial Energy's integral molten salt reactor (IMSR) to provide zero-emission power to industrial facilities and large data centers.

The companies signed a memorandum of understanding in April to jointly develop commercial opportunities with high-energy users looking for reliable, affordable, and zero-carbon baseload supply. Terrestrial Energy said that working with Schneider “offers solutions to the major energy challenges faced by data center operators and many heavy industries operating a wide range of industrial processes such as hydrogen, ammonia, aluminum, and steel production.”

Another year, another stellar performance by America’s nuclear plants. We’ve come to expect high capacity factors, and it’s a credit to the men and women of the profession. They’ve made routine something that was unimaginable not so long ago.

The decadal challenge for the nuclear enterprise now is to maintain this high level of operational excellence for the current fleet, while at the same time ushering in a new generation of technologies at scale. It will be a big job—but one that seems more and more likely with each passing day.

It is against this hopeful backdrop that I take the opportunity to update you on our latest steps toward making the American Nuclear Society a class-leading professional society.

The busyness of the nuclear fuel supply chain

With all that is happening in the industry these days, the nuclear fuel supply chain is still a hot topic. The Russian assault in Ukraine continues to upend the “where” and “how” of attaining nuclear fuel—and it has also motivated U.S. legislators to act.

Two years into the Russian war with Ukraine, things are different. The Inflation Reduction Act was passed in 2022, authorizing $700 million in funding to support production of high-­assay low-enriched uranium in the United States. Meanwhile, the Department of Energy this January issued a $500 million request for proposals to stimulate new HALEU production. The Emergency National Security Supplemental Appropriations Act of 2024 includes $2.7 billion in funding for new uranium enrichment production. This funding was diverted from the Civil Nuclear Credits program and will only be released if there is a ban on importing Russian uranium into the United States—which could happen by the time this column is published, as legislation that bans Russian uranium has passed the House as of this writing and is headed for the Senate. Also being considered is legislation that would sanction Russian uranium. Alternatively, the Biden-Harris administration may choose to ban Russian uranium without legislation in order to obtain access to the $2.7 billion in funding.
