Abstract

''Purnima'', a zero energy fast reactor, is in latest addition to the family of reactors at Trombay. The extremely small mean prompt neutron life-time (1) and a low delayed neutron fraction ( BETA /sub eff/) of this concentrated Pu/ sup 239/ fuelled fast critical assembly d emand quick-acting and highly efficient control and safety systems. The salient features of the control and safety system of this reactor are examined. The description includes, general requirements for safety and control systems, primary control signal, safety devices, control rods, and control logic. Greater emphasis has been placed on safety rather than reliability. Fail-safe methods have been adopted to the maximum possible extent. (INIS)
