The project should include a uranium-fueled reactor core, a system for converting nuclear energy into usable energy, a temperature control system for cooling the reactor, and a distribution system that provides at least 40 kW of continuous electricity for 10 years of operation in the lunar environment.
The reactor must be turned on and off without human assistance. Transportation to another lunar site offers simplicity and convenience.
The reactor has the usual requirements for all spacecraft – lightness and small dimensions. When launched from Earth to the Moon, it must fit inside a cylinder 4 meters in diameter and 6 meters long. It must not weigh more than 6,000 kilograms.
22 applications from different companies have already been submitted. Companies may not even belong to the space industry.
