Summary

In a critical step aimed at bolstering advanced reactor development and their domestic nuclear fuel readiness, the U.S. Department of Energy (DOE) has issued its first round of allocations for high-assay low-enriched uranium (HALEU) under its HALEU Availability Program to five American nuclear developers.

Westinghouse’s eVinci microreactor is a 5-MWe/13-MWth “nuclear battery” designed for off-grid, remote, and mission-critical applications, offering up to eight years of continuous operation without refueling. The heat pipe–cooled microreactor, which uses HALEU-based TRISO fuel in a solid-state monolith core, is engineered for factory fabrication and containerized delivery. The design features no moving parts and supports combined heat and power generation at temperatures up to 600C, making it ideal for applications in mining, military, hydrogen production, and remote industrial facilities.
