The PRISM design has
benefited from the operating experience
of EBR - II, an integral
fast reactor prototype, which was developed by Argonne National Laboratory, and operated for more than 30 years at the Idaho National Laboratory near Idaho Falls, Idaho.
Prism is a sodium - cooled
fast neutron
reactor design built on more than 30 years
of development work,
benefitting from the operating experience
of the EBR - II prototype integral
fast reactor which operated at the USA's Idaho National Laboratory — formerly Argonne National Laboratory — from 1963 to 1994.
