达拉斯初创公司 Actinide 于 2025 年 8 月 26 日在实验室规模下使用其第一代 calutron 电磁同位素分离机完成铀浓缩，成为历史上首家生产高丰度低浓缩铀（HALEU）的初创企业 1。经独立实验室测定，其产出的铀-235 丰度为 15.38%，符合美国法律关于 HALEU（铀-235 含量大于 5% 但小于 20%）的定义 1。该技术可直接产出固态 HALEU，绕过美国目前缺乏的转化产能瓶颈 1。
Actinide 于 2025 年 9 月成立，并于 2026 年 3 月完成由 Onto Ventures 领投的种子轮融资，其首席执行官 Eric Olszewski 投入超过 100 万美元自有资金 1。2025 年，美国民用反应堆业主 77% 的浓缩服务来自国外，其中 26% 来自俄罗斯 1。目前，该公司正在研发第二代分离机 Fortitude，预计单台产能约为美国联邦电磁分离舰队的一半 1。
On August 26, 2025, Actinide, a startup based in Dallas, Texas, became the first startup in history to produce high-assay low-enriched uranium (HALEU) 1. The company achieved this milestone at a laboratory scale using its first-generation calutron electromagnetic isotope separator 1. An independent laboratory verified the uranium-235 enrichment level at 15.38%, which falls within the U.S. legal definition of HALEU as containing more than 5% but less than 20% uranium-235 1. This technology can directly produce solid HALEU, bypassing the conversion capacity bottleneck currently lacking in the United States 1.
This achievement addresses a critical domestic need, as 77% of enrichment services for U.S. commercial reactor owners in 2025 were sourced from abroad, including 26% from Russia 1. Actinide, which was founded in September 2025, is currently developing its second-generation separator named Fortitude 1. A single unit of Fortitude is expected to deliver a capacity roughly equivalent to half of the U.S. federal electromagnetic separation fleet 1. To support its operations, the company completed a seed funding round led by Onto Ventures in March 2026, with CEO Eric Olszewski personally investing over $1 million of his own funds 1.
