Nuclear NewsNEW GAO report analyzes nuclear fuel efforts in national security and commercial sectorsThe Government Accountability Office released a report calling for improved cost reporting and economic analysis regarding federal uranium supply efforts. The agency identified five recommendations for the National Nuclear Security Administration and the Department of Energy to better track long-term expenses and verify the effectiveness of domestic enrichment support programs. These findings highlight the challenges of balancing national security fuel requirements with the emerging commercial market for high-assay low-enriched uranium. While the NNSA projects sufficient inventories for tritiu...Core Content

Nuclear NewsNEW Inertia and LLNL accelerate fusion fuel manufacturingInertia Enterprises and Lawrence Livermore National Laboratory have developed a manufacturing process that reduces the production time for cryogenic deuterium-tritium fuel layers from days to hours. This technique utilizes specialized cooling methods to create smooth fuel ice within carbon capsules, meeting design tolerances verified by existing ignition modeling codes. Transitioning from laboratory experiments to commercial fusion energy requires high-frequency target injection, which necessitates rapid, automated fuel production. By accelerating this process, developers can decrease tritium...Core Content
Core ContentNuclear NewsNEW Second round of Launch Pad selections includes eight newcomersThe National Reactor Innovation Center selected 13 projects from 12 companies for the Nuclear Energy Launch Pad program. This initiative provides private developers with prioritized access to Department of Energy authorization, technical expertise, and testing facilities. The cohort includes eight new participants alongside four companies that recently achieved zero-power fueled criticality, focusing on reactor development and advancements in the nuclear fuel cycle. The National Reactor Innovation Center at Idaho National Laboratory has announced 13 project selections across 12 companies for the Nuclear Energy Launch Pad, a Department of Energy–led program that integrates reactor and fuel facility authorization, testing, and deployment support for private nuclear developers. The Launch Pad emerged from the Reactor Pilot Program and Fuel Line Pilot Program. According to INL, projects selected include reactor development and nuclear fuel cycle advancements, including fabrication, enrichment, and conversion technologies. “These selections show a strong and growing interest from develope...Core Content
