Argonaut Class Reactor: History
Please note this is an old version of this entry, which may differ significantly from the current revision.

The Argonaut class reactor is a design of small nuclear research reactor. Many have been built throughout the world, over a wide range of power levels. Its functions are to teach nuclear reactor theory, nuclear physics and for use in engineering laboratory experiments.

1. Description

The original Argonaut (Argonne Nuclear Assembly for University Training) was built at Argonne National Laboratory and went critical for the first time on February 9, 1957.[1] It was shut down in 1972. This reactor was rated for 10 kilowatts.[2][3]
