About the company
NuCube Energy, Inc. is an advanced nuclear technology company developing factory-built microreactors that deliver steady, carbon-free electricity and high-temperature process heat at the point of use. The Company’s NuSun™ platform is built around a solid-state, heat-pipe-cooled reactor that eliminates the coolant pumps and complex heat exchangers, as well as large pressure vessels found in conventional reactors, supporting a passively safe, walk-away design intended to simplify licensing, lower lifecycle cost, and accelerate commercial scaling compared to other advanced nuclear technologies.
