Argonaut class reactor

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][2][3][4][5][6]}

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.^[7] It was shut down in 1972. This reactor was rated for 10 kilowatts.^[8][9]
