Operation and Control of TRIGA Nuclear Research Reactor with PLC
Keywords:
PLC, regulator rod, shim rod, transient rod, TRIGA Mark-II reactor, emergency core cooling system (ECCS), ladder logic program.Abstract
Nuclear reactor operation and control is a
sophisticated system involving modern equipments and
techniques. This paper proposes an operation and control
feature of TRIGA Mark-II research reactor and discusses the
structure and implementation of smooth automatic operation
and control using programmable logic controller (PLC). The
automation of the reactor and accurate power generation by
demand is carried out by inserting or withdrawing control rods.
Four trip conditions and one external faults (generalized for
any external mechanical or electrical fault) are taken into
account to shut down the reactor suddenly (SCRAM). This
paper proposes better flexibility in operation & control and low
cost & time for trouble shooting with PLC compared to the
instrumentation currently offered by General Atomics for
TRIGA reactor.
