Nicholas Christofilos and the Astron Project in America's Fusion Program
Elisheva Coleman May 4, 2004 Spring Junior Paper Advisor: Professor Mahoney Greek Fire: Nicholas Christofilos and the Astron Project in America’s Fusion Program This paper represents my own work in accordance with University regulations The author thanks the Program in Plasma Science and Technology and the Princeton Plasma Physics Laboratory for their support. Introduction The second largest building on the Lawrence Livermore National Laboratory’s campus today stands essentially abandoned, used as a warehouse for odds and ends. Concrete, starkly rectangular and nondescript, Building 431 was home for over a decade to the Astron machine, the testing device for a controlled fusion reactor scheme devised by a virtually unknown engineer-turned-physicist named Nicholas C. Christofilos. Building 431 was originally constructed in the late 1940s before the Lawrence laboratory even existed, for the Materials Testing Accelerator (MTA), the first experiment performed at the Livermore site.1 By the time the MTA was retired in 1955, the Livermore lab had grown up around it, a huge, nationally funded institution devoted to four projects: magnetic fusion, diagnostic weapon experiments, the design of thermonuclear weapons, and a basic physics program.2 When the MTA shut down, its building was turned over to the lab’s controlled fusion department. A number of fusion experiments were conducted within its walls, but from the early sixties onward Astron predominated, and in 1968 a major extension was added to the building to accommodate a revamped and enlarged Astron accelerator. As did much material within the national lab infrastructure, the building continued to be recycled. After Astron’s termination in 1973 the extension housed the Experimental Test Accelerator (ETA), a prototype for a huge linear induction accelerator, the type of accelerator first developed for Astron. -

Merriman Submitted to the Department of Nuclear Science and Engineering on May 22, 2014 In Partial Fulfillment of the Requirements for the Degree of Bachelor of Science in Nuclear Science and Engineering ABSTRACT Fusion has been "forty years away", that is, forty years to implementation, ever since the idea of harnessing energy from a fusion reactor was conceived in the 1950s. In reality, however, it has yet to become a viable energy source. Fusion's promise and failure are both investigated by reviewing the history of the United States domestic fusion program and comparing technological forecasting by fusion scientists, fusion program budget plans, and fusion program budget history. -
Power to the Planet
POWER A nuclear reactor the size of a wastebasket could TOpower future operations THE on MARS and beyond. PLANET “WE WANT TO TAKE SPACE EXPLORATION TO THE NEXT LEVEL,” says Los Alamos engineer David Poston. “We want to see human habitation on Mars, and we want to see much more scientific data coming back from our deep-space probes.” But when it comes to space exploration, doing more always traces back to the thorny problem of generating more power, and for human habitation on Mars or even our own Moon, a lot more power. Unfortunately, A nuclear reactor the size of a wastebasket could the intensity of sunlight on Mars is less than half of what it is on Earth, and darkness and dust make solar power a severely limited option. Beyond Jupiter, it’s basically not an option at all. Fortunately, a solution may finally be at hand: the “Kilopower” nuclear- fission reactor. It is the present incarnation of an idea that Los Alamos has been considering for decades. Poston, the lead designer, and Patrick McClure, the Los Alamos project lead, have recently returned from power future operations on M A R S and beyond. the Nevada desert, where they successfully tested their concept: a wastebasket-sized and fully autonomous space-based nuclear reactor. McClure and Poston hope to enable nuclear power stations for Mars, the Moon, and the outer solar system. And with a long history of innovation in nuclear, space, and energy technology, Los Alamos has the pedigree to transform this ambitious objective into reality.

Distributed under a Creative Commons Attribution License (CC BY 4.0). Fission power is a promising technology, and it has been proposed for several future space uses. It is being considered for high- power missions whose goal is to explore the solar system and even beyond. Space fission power has made great progress when NASA’s 1 kWe Kilowatt Reactor Using Stirling TechnologY (KRUSTY) prototype completed a full power scale nuclear test in 2018. Its success stimulated a new round of research competition among the major space countries. This article reviews the development of the Kilopower reactor and the KRUSTY system design. It summarizes the current missions that fission reactors are being considered as a power and/or propulsion source. These projects include visiting Jupiter and Saturn systems, Chiron, and Kuiper belt object; Neptune exploration missions; and lunar and Mars surface base missions. -
