Valar Atomics, would-be maker of helium-cooled microreactors, now says it's diversifying into "uranium TRISO-fuel processing to feed its reactors, water desalination, steel manufacturing, critical mineral refining — and data centers." 🔌💡☢️ www.sltrib.com/news/environ...
2 big data centers are coming to Utah’s coal country. How they’ll be powered has residents ‘up in arms.’
“It’s all descending, these data centers,” said Cindy O’Neil, who tracks the progress of the projects. “They’re setting these things within a couple of miles of homes.”

TRISO-X Completes Vertical Construction of TX-1 Fuel Fabrication Facility
X-energy (XE) subsidiary TRISO-X announced on September 24, 2026, that it completed vertical construction of the TX-1 fuel facility in Oak Ridge.The primary structure of the 214,000-square-foot facility is finished. Work now shifts to interior construction, fuel fabrication equipment installation and supporting facilities. Once operational, TX-1 is expected to produce approximately 700,000 fuel pebbles annually, equivalent to 5 metric tons of uranium, with capacity to fuel up to 11 Xe-100 reactors.TRISO-X received a 40-year Special Nuclear Material License for TX-1 from the U.S. Nuclear Regulatory Commission earlier in 2026. The facility is initially intended to support X-energy's proposed Xe-100 project at Dow's Seadrift site in Texas.

☢️🚯 "However, 100yrs post discharge, if >5 TRISO particles (out of ~19000) remain in a pebble post-separation, the graphite might not meet LLW discharge criteria. Achieving this high level of TRISO particle separation from graphite at scale is likely to prove to be a significant technical challenge."
Volumetric discharge of waste generated by TRISO fuel-based nuclear reactor concepts ranged from 4.4x to 16x that of conventional PWRs.
An order of magnitude reduction in waste volume might occur if TRISO particles were separated from the graphite moderator so the latter were disposed of as LLW.
