It uses high-temperature gas reactor design principles with TRISO fuel, a graphite moderator and helium coolant, and is meant to de-risk Valar's technology on the way to full-scale, mass-produced reactors. The reactor was airlifted by the U.S. military in February 2026, and in June 2026 it became the second reactor to reach criticality under the U.S. Department of Energy's reactor pilot program.","url":"https://www.valaratomics.com/ward-250","is_stealth":false,"normalized_domain":"valaratomics.com","normalized_url_key":"valaratomics.com/ward-250","parent_slug":"valar-atomics","parent":{"slug":"valar-atomics","name":"Valar Atomics","listing_type":"company","profile_url":"/companies/valar-atomics"},"type_data":{"product_kind":"hardware"},"logo":"https://valaratomics.com/favicon.png","links":[{"label":"Technology","url":"https://www.valaratomics.com/technology"}],"entry_points":[{"kind":"homepage","url":"https://www.valaratomics.com/ward-250","audience":"human","primary":true,"listed_by":"community","on_listing_domain":true}],"primary_entry_points":{"human":{"kind":"homepage","url":"https://www.valaratomics.com/ward-250","audience":"human","primary":true,"listed_by":"community","on_listing_domain":true},"agent":null},"founders":[],"media":{"logo_asset_id":"d859c786-60a3-4a6c-9d13-a9dfdff432fc"},"categories":["Energy","Nuclear","Hardware"],"stage":null,"founded_year":null,"location":null,"pricing":null,"twitter":"https://x.com/valaratomics","github":null,"linkedin":"https://www.linkedin.com/company/valar-atomics/","contact_email":null,"added_at":"2026-10-10T07:29:49.033Z","added_via":"web","geo":null,"agents":null,"featured_until":null,"example":false,"ownership_status":"unclaimed","claimed_by_agent_id":null,"claimed_via_claim_id":null,"claimed_at":null,"updated_at":"2026-10-10T07:29:49.033Z","is_featured":false,"category_memberships":[{"kind":"product_category","slug":"energy","name":"Energy","note":null,"profile_url":"/categories/energy"},{"kind":"product_category","slug":"hardware","name":"Hardware","note":null,"profile_url":"/categories/hardware"},{"kind":"product_category","slug":"nuclear","name":"Nuclear","note":null,"profile_url":"/categories/nuclear"}],"membership":{"note":null,"source":"listing","added_via":"web","added_at":"2026-10-10T07:29:49.033Z","updated_at":"2026-10-10T07:29:49.033Z"}},{"listing_type":"product","name":"Fluxnium Seawater Uranium Adsorption","slug":"fluxnium-seawater-uranium","tagline":"Polymer-fiber system that adsorbs uranium from seawater for yellowcake supply","description":"Fluxnium's core product approach uses proprietary high-surface-area polymer fibers that passively adsorb dissolved uranium as seawater moves past them.
