‘Game changing’ space-mission power system passes tests with flying colors

KRUSTY experiment demonstrates fission power’s promise for lunar, planetary exploration

Los Alamos, NM, May 2, 2018 — A new nuclear power system that could enable long-duration crewed missions to the Moon, Mars and destinations beyond recently passed an extensive operating test in the Nevada desert, performing well under a variety of challenging conditions. 

“We threw everything we could at this reactor, in terms of nominal and off-normal[BA(1]  operating scenarios and KRUSTY passed with flying colors,” said David Poston of Los Alamos National Laboratory, the chief reactor designer. 

The recent experiment in Nevada, conducted by NASA and the Department of Energy’s National Nuclear Security Administration (NNSA), demonstrated the system can create electricity with fission power and showed the system is stable and safe no matter what environment it encounters. 

The agency announced the results of the demonstration, called the Kilopower Reactor Using Stirling Technology (KRUSTY) experiment, during a news conference today at its Glenn Research Center in Cleveland. The Kilopower experiment was conducted at the NNSA’s Nevada National Security Site from November 2017 through March.  

“Safe, efficient and plentiful energy will be the key to future robotic and human exploration,” said Jim Reuter, NASA’s acting associate administrator for the Space Technology Mission Directorate (STMD) in Washington. “I expect the Kilopower project to be an essential part of lunar and Mars power architectures as they evolve.” 

Kilopower is a small, lightweight fission power system capable of providing up to 10 kilowatts of electrical power - enough to run several average households - continuously for at least 10 years. Four Kilopower units would provide enough power to establish an outpost. A video explains how kilopower works.   

According to Marc Gibson, lead Kilopower engineer at Glenn, the pioneering power system is ideal for the Moon, where power generation from sunlight is difficult because lunar nights are equivalent to 14 days on Earth. 

“Kilopower gives us the ability to do much higher power missions, and to explore the shadowed craters of the Moon,” said Gibson. “When we start sending astronauts for long stays on the Moon and to other planets, that’s going to require a new class of power that we’ve never needed before.” 

The prototype power system uses a solid, cast uranium-235 reactor core, about the size of a paper towel roll. Passive sodium heat pipes transfer reactor heat to high-efficiency Stirling engines, which convert the heat to electricity.  

The Kilopower team conducted the experiment in four phases. The first two phases, conducted without power, confirmed that each component of the system behaved as expected. During the third phase, the team increased power to heat the core incrementally before moving on to the final phase. The experiment culminated with a 28-hour, full-power test that simulated a mission, including reactor startup, ramp to full power, steady operation and shutdown. 

Throughout the experiment, the team simulated power reduction, failed engines and failed heat pipes, showing that the system could continue to operate and successfully handle multiple failures. 

The Kilopower project is developing mission concepts and performing additional risk reduction activities to prepare for a possible future flight demonstration. The project will remain a part of the STMD’s Game Changing Development program with the goal of transitioning to the Technology Demonstration Mission program in Fiscal Year 2020.   

Such a demonstration could pave the way for future Kilopower systems that power human outposts on the Moon and Mars, including missions that rely on In-situ Resource Utilization to produce local propellants and other materials. 

The Kilopower project is led by Glenn, in partnership with NASA’s Marshall Space Flight Center in Huntsville, Alabama, and NNSA, including its Los Alamos National Laboratory, Nevada National Security Site and Y-12 National Security Complex.
