RIPB safety case for TerraPower’s MCRE

February 13, 2024, 7:00AMNuclear News

Last month at the American Nuclear Society’s Risk-informed, Performance-based Principles and Policy Committee’s (RP3C’s) Community of Practice (CoP), Brandon Chisholm presented “Development of a Risk-Informed and Performance-Based Safety Case for TerraPower’s Molten Chloride Reactor Experiment (MCRE).” RP3C holds a CoP on the last Friday of the month from 3:00 p.m. to 4:00 p.m. (ET), and participation is open to all professionals interested in RIPB principles and practices. Chisholm’s January 26 presentation is available to stream on YouTube.

The Department of Energy announced February 7 that fuel for the MARVEL microreactor, which Idaho National Laboratory plans to host inside the Transient Reactor Test (TREAT) facility, is now being fabricated by TRIGA International, with the first fuel delivery expected in spring 2025. MARVEL operation was expected “by the end of 2024” as recently as May 2023, but that timeline had shifted by October, when the DOE said MARVEL “is expected to be completed in early 2025.” Now, according to the DOE’s latest announcement, “Fuel loading for MARVEL is anticipated to occur in 2026, with the microreactor expected to be on line by 2027.”

The Department of Energy Office of Environmental Management’s Office of River Protection and contractor Washington River Protection Solutions have completed the first waste processing campaign through the Tank-Side Cesium Removal (TSCR) system at the Hanford Site.

Zeno Power will repurpose legacy radioisotope source from ORNL

January 31, 2024, 12:03PMNuclear News

Zeno Power announced on January 26 that it will get the strontium-90 that it needs to fuel full-scale radioisotope power systems (RPSs) for national security and space exploration missions from the Department of Energy’s Oak Ridge Office of Environmental Management (OREM). Under a public-private partnership, a large legacy RPS known as the BUP-500 that had languished, unused, in storage at Oak Ridge National Laboratory has been transported to an unnamed commercial radiological facility in Pennsylvania—Zeno Power’s subcontractor—where the Sr-90 it contains will be repurposed as heat sources for Zeno Power devices.

L&A to increase support for Post Foundation STEM scholarships

To honor the 50th anniversary of Waste Management Symposia (WMS), Longenecker & Associates (L&A) has announced an increase in its financial support for WMS’s scholarship efforts.

Since launching a 10-year commitment in 2019, L&A has contributed $125,000 to the Post Foundation, which provides scholarships for students pursuing careers in the safe management in nuclear materials and supports their participation in the annual WMS conference on the management of radioactive waste and related topics.

Next-gen workforce development for nuclear waste disposal R&D

January 11, 2024, 12:07PMANS News

The Department of Energy, in conjunction with Massachusetts Institute of Technology and Texas A&M University, will conduct a biweekly webinar series aimed at providing a broad overview of nuclear waste management and disposal in the United States as well as the latest research activities. The target audience is undergraduate and graduate students in science, engineering, policy, sociotechnical, and social science programs.

2023 in Review: April–June

January 11, 2024, 7:00AMNuclear News

Another calendar year has passed. Before heading too far into 2024, let’s look back at what happened in 2023 in the nuclear community. In today's post, compiled from Nuclear News and Nuclear Newswire are what we feel are the top nuclear news stories from April through June 2023.

Stay tuned for the top stories from the rest of the past year.

DOE rolls out simplified HALEU enrichment RFP, opens door to LEU from allies

The Department of Energy issued a final request for proposals (RFP) on January 9 for uranium enrichment services to help establish a commercial domestic supply of high-assay low-enriched uranium (HALEU) to fuel a potential fleet of advanced reactors. Without HALEU, advanced reactors will not be able to proceed past the demonstration stage. And given the investments of capital and time required to license and build a nuclear power plant—even a smaller, more efficient advanced reactor—eliminating fuel uncertainty could be what a utility needs to invest in new construction.

Notes from an international workshop on spent fuel management

The Department of Energy’s Office of Environmental Management issued for public comment the first request for qualifications (RFQ) related to the department’s Cleanup to Clean Energy initiative, which aims to increase energy production by making DOE land available for the potential development of carbon-free energy (CFE) electricity generation through leases.

The Office of Fusion Energy Sciences (FES) in the Department of Energy’s Office of Science introduced a new plan—"Building Bridges: A Vision for the Office of Fusion Energy Sciences”—during a Fusion Energy Sciences Advisory Committee (FESAC) hearing on December 13, and announced that news December 14. What’s included? A plan for the DOE to “establish the steps needed to help advance fusion energy, including addressing key science and technology gaps in the supply chain and industry.” The vision is less a guiding document than a preview of DOE-FES’s near-term intentions, which include drafting a fusion science and technology road map in 2024 to shape investments for the coming decade.

Nuclear power and The Simpsons

In the episode “Duffless” in season 4 of The Simpsons, Homer is deep in the bowels of the Springfield Nuclear Power Plant when he encounters a gigantic mutant spider. He turns to a map that says, “To overcome the spider’s curse, simply quote a Bible verse.” Homer starts with, “Uh, thou shalt not . . .” but then, unable to remember anything from the Bible, he instead brains the spider with a rock. This sort of nuttiness is often how we’ve depicted the power plant on the show, where I’ve been a writer and producer for 20 seasons.

National lab partnerships speed nuclear deployment

“The tools of the academic designer are a piece of paper and a pencil with an eraser. If a mistake is made, it can always be erased and changed. If the practical-reactor designer errs, he wears the mistake around his neck; it cannot be erased. Everyone sees it.”

Many in the nuclear community are familiar with this sentiment from Admiral Rickover. A generation of stagnation in the industry has underscored the truth of his words. But as economies around the world put a price on carbon emissions, there’s a renewed sense of urgency to deploy clean energy technologies. This shifts the global balance of economic competitiveness, and it’s clear that the best path forward for nuclear requires combining the agility of private innovators with the technology and capabilities of national laboratories.
