NUCLEAR REACTOR ON MOON

Dec. 28, 2020

USA’s plan to have the first nuclear reactor on the moon by the end of 2026 — for which the US Department of Energy in collaboration with Nasa intends to solicit industry design proposals in early 2021 — got an impetus with a recent White House directive.

About:

On December 16, outgoing President Donald Trump, issued the “National Strategy for Space Nuclear Power and Propulsion”.
Under it, he asked Nasa to “initiate fission surface power project for lunar surface demonstration by 2027 with scalability to a power range of 40 kilowatt-electric and higher to support a sustained lunar presence and exploration of Mars”.
NASA aims to establish a flight hardware system that is ready for integrating with the lunar lander by 2026-end. The fission power system — as the nuclear reactor is called — will benefit future robotic and human exploration missions to the moon as well as Mars.
The availability of safe, efficient, and readily available power is critical to these missions and a fission surface power system meets those requirements.
The fission surface power system will be fully manufactured and assembled on earth and integrated on a lander as a payload.
The system — consisting of four major subsystems including a nuclear reactor, an electric power conversion unit, heat rejection array, and power management and distribution subsystem — will be designed to operate for up to 10 years.
