Revolutionary Modular Nuclear Reactor Core for Space Exploration

Rotating Fuel Core with Fuel Strip(s) ("ROFFUS") is an innovative modular nuclear reactor core designed to provide reliable and scalable power for advanced space missions.

The Need

Future space missions require dependable, high-output energy sources to support operations such as material processing, transportation, and thermal conditioning, particularly in challenging environments like the lunar poles where sunlight is scarce.

The Technology

This advanced nuclear reactor core features a series of fuel modules, each containing nuclear fuel and equipped with a fuel-module actuator that enables rotation for optimal reaction control. The reactor includes neutron sources capable of initiating and sustaining a fission chain reaction within the fuel modules. The modular design allows for flexible integration with various power systems and ensures consistent energy output even in the harsh conditions of space. A built-in controller regulates the fission rate to maintain safe and efficient operation, while a thermionic energy converter transforms generated heat into usable electricity.
