supercritical reactor

[¦sü·pər′krid·ə·kəl rē′ak·tər]
(nucleonics)
A nuclear reactor in which the effective multiplication constant is greater than 1 and consequently a reactor that is increasing its power level; if uncontrolled, a supercritical reactor will undergo a sudden and dangerous rise in power level.
