subcritical reactor

(nucleonics)
A reactor having an effective multiplication constant of less than one, so that a self-supporting chain reaction cannot be maintained. Also known as subcritical assembly; teaching reactor.

This idea has also been around in theory since the early 1950s; it gained renewed currency in 1993, when Nobel Prizewinning physicist Carlo Rubbia proposed an "energy amplifier," an accelerator-driven subcritical reactor (ADSR) that coupled a particle accelerator to a reactor core containing thorium, depleted uranium, or other mildly radioactive materials.
The neutronic characteristics of the subcritical reactor have been extensively studied theoretically [4, 5] and experimentally [6-8].
The idea for this accelerator-driven subcritical reactor (ADSR), as it is known, has been sitting on nuclear physicists' drawing-boards for the past 20 years.
