At the end of April, TerraPower announced that it had officially begun construction on its Natrium power plant in Kemmerer, Wyo.—one of the two full-scale demonstration projects in the Department of Energy’s Advanced Reactor Demonstration Program.

Now, the second ARDP-backed demonstration project, which aims to see the deployment of X-energy’s Xe-100 at a Dow chemical facility, has reached a new milestone of its own. On May 18, X-energy announced that the Nuclear Regulatory Commission has completed its environmental assessment of the proposed Long Mott Generating Facility and issued a finding of no significant impact (FONSI).

X-energy recently announced that it has begun collaborating with Louisville Gas and Electric Company and Kentucky Utilities to deploy X-energy’s Xe-100 reactor in Kentucky. The news comes soon after X-energy went public on the Nasdaq and represents the latest in a string of growing investments Kentucky has made in nuclear development over the last two years.

X-energy announced Thursday that it has signed a letter of intent with Talen Energy to assess the deployment of X-energy’s Xe-100 reactor in Pennsylvania and throughout the market area of the PJM Interconnection regional transmission organization. That area, where the companies intend to explore the deployment of at least three four-unit Xe-100 power plants, includes several states in the eastern United States, from New Jersey to Illinois.

It has been an unusually busy week in the world of West Coast nuclear legislative momentum. In California, a bill is aiming to effectively repeal the state’s nuclear moratorium, while in Oregon, new legislation would have the state create a nuclear feasibility study.

Now, in Washington state, legislators are introducing various measures to move new nuclear prospects forward. One motion requests that Gov. Bob Ferguson respond to the Department of Energy’s request for information regarding states hosting Nuclear Lifecycle Innovation Campuses.

The Nuclear Regulatory Commission has granted X-energy subsidiary TRISO-X a special nuclear material license for high-assay low-enriched uranium fuel fabrication. The license applies to TRISO-X’s first two planned commercial facilities, known as TX-1 and TX-2, for an initial 40-year period. The facilities are set to be the first new nuclear fuel fabrication plants licensed by the NRC in more than 50 years.

Advanced reactor developer X-energy has announced that it has closed an oversubscribed Series D financing round of approximately $700 million. The funding proceeds are expected to be used to help continue the expansion of its supply chain and the commercial pipeline for its Xe-100 advanced small modular reactor and TRISO-X fuel, according the company.

A year ago this month, Amazon led a $500 million investment in X-energy, alongside Citadel founder Ken Griffin, the University of Michigan, and other investors. In addition to that financing, Amazon pledged to support the development of an initial four-unit, 320-MW project with Energy Northwest in Washington state.

The Department of Energy has fast-tracked its selections for the Fuel Line Pilot Program. Four companies—Oklo, Terrestrial Energy, TRISO-X, and Valar Atomics—were named September 30 as “conditional selections” for a “fast-track approach to commercial licensing,” bringing the total to five. The first company conditionally chosen for a DOE-authorized fuel fabrication facility—Standard Nuclear—was named less than three weeks after the program opened to applicants in July.

President Trump will arrive in the United Kingdom this week for a state visit that promises to include the usual pomp and ceremony alongside the signing of a landmark new agreement on U.S.-U.K. nuclear collaboration.

Small modular reactor developer X-energy, together with its fuel-developing subsidiary TRISO-X, has selected Clark Construction Group to finish the building construction phase of its advanced nuclear fuel fabrication facility, known as TX-1, in Oak Ridge, Tenn. It will be the first of two Oak Ridge facilities built to manufacture the company’s TRISO fuel for use in its Xe-100 SMR. The initial deployment of the Xe-100 will be at Dow Chemical Company’s UCC Seadrift Operations manufacturing site on Texas’s Gulf Coast.

The Nuclear Regulatory Commission is providing the opportunity to request a hearing on Dow Chemical Company’s application to construct a 320-MWe nuclear power plant at the company’s Seadrift site in Calhoun, Texas. Long Mott Energy, a wholly owned subsidiary of Dow Chemical, submitted its construction permit application to the NRC in March. It was accepted for review by the agency on May 12.

As state legislatures nationwide near the end of their spring sessions, nuclear advocates hope to spur momentum on Texas legislation that would provide taxpayer-funded grants to developers of new nuclear technology in the state.

Dow and X-energy announced today that they have submitted a construction permit application to the Nuclear Regulatory Commission for a proposed advanced nuclear project in Seadrift, Texas. The project could begin construction later this decade, but only if Dow confirms “the ability to deliver the project while achieving its financial return targets.”

In February, the Community of Practice (CoP) webinar series, hosted by the American Nuclear Society Standards Board’s Risk-informed, Performance-based Principles and Policies Committee (RP3C), celebrated its fifth anniversary. Like so many online events, these CoPs brought people together at a time when interacting with others became challenging in early 2020. Since the kickoff CoP, which highlighted the impact that systems engineering has on the design of NuScale’s small modular reactor, the last Friday of most months has featured a new speaker leading a discussion on the use of risk-informed, performance-based (RIPB) thinking in the nuclear industry. Providing a venue to convene for people within ANS and those who found their way online by another route, CoPs are an opportunity for the community to receive answers to their burning questions about the subject at hand. With 50–100 active online participants most months, the conversation is always lively, and knowledge flows freely.

Texas lawmakers are considering legislative action this session on recommendations made last November by the Texas Advanced Nuclear Reactor Working Group.

Senate Bill 1105 calls for the establishment of a state-run advanced nuclear energy authority, a state permitting office, and an advanced nuclear innovation fund. Republican state Sen. Tan Parker introduced the bill.

Nuclear footprint: Texas currently has two large nuclear plants—Commanche Peak and South Texas Project—comprising four reactors that supplied nearly 10 percent of the state’s power last year.

Small modular reactors are also planned in Texas. Dow Chemical and X-energy are targeting a cluster of SMRs to support Dow’s manufacturing site in Seadrift on the Gulf Coast. At Abeline Christian University, about 200 miles west of Dallas, Natura Resources plans to install a test reactor using molten-salt cooling.

The media have gleefully resurrected the language of a past nuclear renaissance. Beyond the hype and PR, many people in the nuclear community are taking a more measured view of conditions that could lead to new construction: data center demand, the proliferation of new reactor designs and start-­ups, and the sudden ascendance of nuclear energy as the power source everyone wants—or wants to talk about.

Once built, large nuclear reactors can provide clean power for at least 80 years—outlasting 10 to 20 presidential administrations. Smaller reactors can provide heat and power outputs tailored to an end user’s needs. With all the new attention, are we any closer to getting past persistent supply chain and workforce issues and building these new plants? And what will the election of Donald Trump to a second term as president mean for nuclear?

As usual, there are more questions than answers, and most come down to money. Several developers are engaging with the Nuclear Regulatory Commission or have already applied for a license, certification, or permit. But designs without paying customers won’t get built. So where are the customers, and what will it take for them to commit?

There is extra significance to the American Nuclear Society holding its annual meeting in Orlando, Florida, this past week. That’s because in 1967, the state of Florida passed a law allowing Disney World to build a nuclear power plant.

As a primer to the American Nuclear Society Winter Conference and Expo, ANS Executive Director/Chief Executive Craig Piercy hosted a panel discussion titled “The State of Nuclear,” sponsored by the ANS Trustees of Nuclear. The October 29 discussion, the first in a two-part series, featured five thought leaders from the nuclear community as they reviewed the current state of nuclear power. The second panel will take place during the ANS Winter Conference in Orlando, Fla., on November 18.

Tech giant Amazon announced Wednesday new partnerships with Dominion Energy and X-energy to develop and deploy 5 gigawatts of nuclear energy to power needs across the country over the next 15 years.

New testing done at China’s Shidaowan nuclear power plant has confirmed its ability to be naturally cooled down, an industry-first milestone for achieving commercial-scale inherent safety, according to researchers.
