Lockheed Martin to Develop Compact Fusion Reactor Prototype in Five Years

According to Aviation Week, Lockheed Martin has been quietly working on a compact fusion reactor which could, with an estimated 25 kg of fuel, "run an entire year of operations."

Although the first-generation reactors will have radioactive parts at the ends of their lives, such as some steel elements in the shell, McGuire says the contamination situation “is an order of magnitude better” than that of contemporary fission systems. “There is no long-lived radiation. Fission reactors’ stuff will be there forever, but with fusion materials, after 100 years then you are good.” Contamination levels for fusion will improve with additional materials research, he believes. “It’s been a chicken-and-egg situation. Until we’ve had a good working fusion system, there has not been money to go off and do the hard-core materials research,” McGuire says. “So we believe the first generation is good enough to go out and do, and then it will only improve in time.” Old CFR steel shell parts can be disposed of with “a shallow burial in the desert, similar to medical waste today. That’s a major difference to today’s fission systems.”
