It was an [[Argonaut class reactor|Argonaut series]] 10&nbsp;kW [[research reactor]] designed by the US [[Argonne National Laboratory]], and was used by the [[Royal Navy]] for experimental and training purposes.<ref>{{Cite book|title=Decommissioning of research reactors : evolution, state of the art, open issues.|date=2006|publisher=International Atomic Energy Agency|isbn=9201126050|location=Vienna|oclc=71317149}}</ref><ref>{{cite journal |last1=Lockwood |first1=Rick |last2=Beeley |first2=Philip |year=1999 |title=Just another source of neutrons?

JASON was one of very few reactors operating within a major population centre ([[History of Queen Mary University of London#Nuclear reactor|another was at Queen Mary]] in east London)– and undoubtedly the only one installed in a 17th-century building. The Royal Naval College building was the former [[Greenwich Hospital (London)|Greenwich Hospital]], built between 1696 and 1712 by [[Christopher Wren]], where the reactor was located within the King William Building. The existence of a nuclear reactor so close to central London was largely unknown to the general public, even at the time that "Maritime Greenwich" was named a [[UNESCO]] [[World Heritage Site]] in 1997.
