US companies team up to bring nuclear microreactors to federal sites

US-based NANO Nuclear Energy Inc., a developer of advanced nuclear micro modular reactors, has partnered with renewable energy firm Ameresco to explore deploying nuclear microreactors at federal and commercial sites across the United States. Announced in January 2026, the non-binding memorandum of understanding (MoU) outlines a joint assessment of siting, licensing, construction, operation, and decommissioning pathways for NANO Nuclear’s modular microreactors, focusing primarily on the KRONOS system, with additional evaluation of the ZEUS and LOKI designs. These microreactors are designed to provide reliable, dispatchable power either off-grid or connected to existing grids, targeting applications such as federal facilities, data centers, and industrial sites. The collaboration aims to integrate these advanced nuclear technologies into next-generation energy infrastructure to support the nation’s energy transition with safe and resilient power solutions. Ameresco, which works extensively with government agencies and institutional customers, views this partnership as part of its strategy to diversify its clean
