Abstract
The present invention relates to a procedure execution system for a small modular reactor power plant and a procedure execution method using the same. The procedure execution system according to the present invention includes an operating state determination unit that determines whether an alarm occurs in the small modular reactor; a procedure processing unit that processes a procedure; and an input unit that receives input from an operator. The procedure processing method of the procedure processing unit includes a first mode in which steps and instructions of the procedure are presented to the operator and the operator processes the steps and instructions of the procedure through the input unit, and a second mode in which the steps and instructions of the procedure are automatically executed based on state information of the small modular reactor. When the operating state determination unit determines that an alarm has occurred, the procedure processing unit switches from the first mode to the second mode.
