# NuCube Advances Utah Microreactor Demonstration

NuCube Energy plans to complete a high-temperature infrastructure demonstration for its proposed NuSun microreactor at the Utah San Rafael Energy Lab in Orangeville by 2027. The work involves state and university research partners and is intended to test reactor heat and heat-transfer systems, potentially informing later reactor siting and licensing. No solicitation, contract value, or awarded contract has been identified.

- The demonstration may create future demand for high-temperature testing, heat-transfer systems, reactor infrastructure, and licensing support.
- Companies with capabilities in these areas can assess how their offerings align with the demonstration and potential follow-on work; this is a prospective market signal, not an active procurement opportunity.
- NuCube Energy and Idaho State University were selected as developers in the DOE Nuclear Energy Launch Pad in April 2026, providing context for the project’s federal and university research connections.
