microreactor technical

"we plan to site, design, and commission a NuCube microreactor on campus"

A microreactor is a very small, factory-built nuclear power unit designed to produce electricity and heat for a single site or a small grid, much like a compact, highly engineered backup generator for towns, mines, ships or remote industrial sites. Investors care because microreactors promise faster construction, lower upfront cost and flexible deployment compared with large plants, while offering revenue potential alongside regulatory, safety and long-term maintenance risks.
