NuCube LinkedIn Post:

Nuclear power is becoming smaller, simpler, and more deployable.

We are developing the NuSunᵀᴹ platform as a factory-built microreactor designed to deliver firm, carbon-free power and high-temperature heat on site.

Unlike large conventional plants built around a single location, modular microreactors are designed to bring energy closer to where it is needed. For NuCube, that means one platform aimed at three core markets: microgrids and remote sites, industrial heat, and data centers or other behind-the-meter energy users.

The goal? Productize nuclear energy for repeatable deployment.
