NASA's portable nuclear reactor could power missions to Mars
Washington, May 3: NASA has said that it successfully demonstrated a new nuclear reactor power system that could enable crewed missions to the Moon, Mars and destinations beyond.
NASA announced the results of the demonstration, called the Kilopower Reactor Using Stirling Technology (KRUSTY) experiment on Wednesday at its Glenn Research Center in Cleveland.
The Kilopower experiment was conducted at the US Department of Energy's National Nuclear Security Administration's Nevada National Security Site from November 2017 through March.
Such a demonstration could pave the way for future Kilopower systems that power human outposts on the Moon and Mars, NASA said in a statement.
"Safe, efficient and plentiful energy will be the key to future robotic and human exploration," said Jim Reuter of NASA's Space Technology Mission Directorate in Washington.
"I expect the Kilopower project to be an essential part of lunar and Mars power architectures as they evolve," Reuter said.
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.
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, said Marc Gibson, lead Kilopower engineer at Glenn.
"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 purpose of the recent experiment in Nevada was twofold: to demonstrate that the system can create electricity with fission power, and to show the system is stable and safe no matter what environment it encounters, said David Poston of National Nuclear Security Administration's Los Alamos National Laboratory.
"We threw everything we could at this reactor, in terms of nominal and off-normal operating scenarios and KRUSTY passed with flying colours," said Poston.

New Delhi (PTI): Prime Minister Narendra Modi on Tuesday called on Vice President C P Radhakrishnan to greet him on Tamil new year Puthandu.
Modi reached the vice president's official residence here and offered prayers on the occasion of Puthandu.
"Called on Vice President Thiru C P Radhakrishnan Ji and conveyed greetings on the special occasion of Puthandu. Praying for a wonderful year ahead, filled with good health and happiness," Modi posted on X.
The vice president said he was happy to meet Modi at Uprashtrapati Bhawan and exchange greetings on Tamil Puthandu and Baisakhi.
"We prayed for a wonderful year ahead, with happiness, peace, and the well-being of all.
"We discussed how Tamil Puthandu showcases the wisdom of our ancestors and brings together tradition, family, spirituality, and a disciplined way of life," he posted on X.
Separately, Radhakrishnan greeted people on the occasion of Puthandu, Baisakhi, Rongali Bihu, Maha Bishuba Pana Sankranti, Poila Boishakh and Vishu.
"These vibrant festivals reflect the spirit of Ek Bharat Shreshtha Bharat and celebrate the rich cultural diversity of our nation," he said.
Radhakrishnan said the festivals mark new beginnings, the joy of harvest, and the enduring bond between people, nature, and tradition.
"May these occasions inspire harmony, prosperity and renewed hope to everyone's lives," he prayed.
