Significant Functions of SCRAM with Associated Alarms for RTP Safe Operation

Full-text:A reactor SCRAM is the rapid insertion or fall of all control rods into the core to instantaneously stop the fission chain reaction. This action can be accomplished automatically or manually by the reactor operator to immediately shut down the reactor when certain predetermined parameters indicate that reactor is not operating as expected. Control rods are essential for safe control of nuclear reactors as their prompt action and response to the reactor are indispensable. SCRAM functions are integrated with alarms to alert the reactor operators so they can respond quickly and efficiently.This paper aims to define the SCRAM functionability for RTP safe operation including related test procedures as well as control rod mechanism during SCRAM.
