Ted Garrish faces Senate committee for DOE nuclear post

May 2, 2025, 9:30AMNuclear News

Garrish

A veteran nuclear leader with more than four decades of experience testified before a U.S. Senate committee on Wednesday as part of the nomination process to become the next NE-1, the Department of Energy’s assistant secretary for nuclear energy.

Theodore “Ted” Garrish appeared before the Senate Committee on Energy & Natural Resources to answer questions about how he would approach the position—which he last held from 1987 to 1989, during the Ronald Reagan administration.

Garrish told the committee he has dedicated his career to energy—especially nuclear energy—and has worked mostly in public service positions, including posts in the DOE and Office of International Affairs.

The committee will advance Garrish’s nomination to the full U.S. Senate for a final vote, but no timeline was laid out.

Delivering new nuclear on time, the first time

The nuclear industry is entering a period of renewed urgency, driven by the need for stable baseload power, heightened energy security concerns, and expanded defense infrastructure. Now more than ever, we must deliver new nuclear projects on time and on budget to maintain public trust and industry momentum.

The importance of execution certainty cannot be overstated—public trust, industry investment, and future deployment all hinge on our ability to deliver these projects successfully. However, history has shown that cost overruns and schedule delays have eroded confidence in the industry’s ability to deliver nuclear construction. As we embark on many first-of-a-kind (FOAK) reactor builds, fuel cycle infrastructure projects, and extensive defense-related nuclear projects, we must ensure that execution certainty is no longer an aspiration—it is an expectation.

International Atomic Energy Agency director general Rafael Mariano Grossi recently traveled to Washington, D.C., for the first time since Trump took office in January. In his three-day visit to the capital, Grossi spoke with key nuclear leaders from around the world and in the federal government, including Energy Secretary Chris Wright and Nuclear Regulatory Commission chair David Wright, on topics including nuclear power, safety, security, funding, and nonproliferation.

Curiosity landed on Mars sporting a radioisotope thermoelectric generator (RTG) in 2012, and a second NASA rover, Perseverance, landed in 2021. Both are still rolling across the red planet in the name of science. Another exploratory craft with a similar plutonium-238–fueled RTG but a very different mission—to fly between multiple test sites on Titan, Saturn’s largest moon—recently got one step closer to deployment.

On April 25, NASA and the Johns Hopkins University Applied Physics Laboratory (APL) announced that the Dragonfly mission to Saturn’s icy moon passed its critical design review. “Passing this mission milestone means that Dragonfly’s mission design, fabrication, integration, and test plans are all approved, and the mission can now turn its attention to the construction of the spacecraft itself,” according to NASA.

Idaho National Laboratory is looking for a sponsor to invest $5 million–$10 million in a privately funded innovation incubator to support seed-stage start-ups working in nuclear energy, integrated energy systems, cybersecurity, or advanced materials. For their investment, the sponsor gets access to what INL calls “a turnkey source of cutting-edge American innovation.” Not only are technologies supported by the program “substantially de-risked” by going through technical review and development at a national laboratory, but the arrangement “adds credibility, goodwill, and visibility to the private sector sponsor’s investments,” according to INL.

Here is a recap of industry happenings from the recent past:

ADVANCED REACTOR MARKETPLACE

TerraPower’s Natrium reactor advances on several fronts

TerraPower has continued making aggressive progress in several areas for its under-construction Natrium Reactor Demonstration Project since the beginning of the year. Natrium is an advanced 345-MWe reactor that has liquid sodium as a coolant, improved fuel utilization, enhanced safety features, and an integrated energy storage system, allowing for a brief power output boost to 500-MWe if needed for grid resiliency. The company broke ground for its first Natrium plant in 2024 near a retiring coal plant in Kemmerer, Wyo.

“We are building a fusion machine and testing all equipment—including components and a pulser module—at our Pacific Fusion test center,” Pacific Fusion cofounder and chief technology officer Keith LeChien told Nuclear News. “GA’s engineering expertise remains an important part of our progress, and we expect this collaboration to continue through future phases of development.”

UIUC microreactor fuel qualification methodology gets safety approval

April 24, 2025, 9:34AMNuclear News

The University of Illinois at Urbana-Champaign Nuclear Plasma and Radiation Engineering (NPRE) Department announced yesterday that the Nuclear Regulatory Commission has approved a fuel qualification methodology topical report for the high-temperature gas-cooled reactor the university wants to construct. The topical report was prepared by Ultra Safe Nuclear and submitted by UIUC to the NRC in March 2024. It describes the fuel that would be used in the microreactor that UIUC plans to host—initially containing uranium enriched to 9.9 percent U-235—and how it would be tested. The NRC issued its approval and a final safety evaluation on April 1.
