Zusammenfassung: | Provided are a method for verifying abnormal operation procedures of a nuclear power plant and a performing system thereof, the method comprising the steps of: acquiring at least one operation variable related to the abnormal state of a nuclear power plant by simulating an abnormal operating scenario using a simulator; training an artificial neural network using the at least one operation variable so that the artificial neural network can determine the abnormal state of the nuclear power plant; calculating the contribution of the at least one operation variable by inverting the training result of the artificial neural network; and deriving an operation variable that influences the determination of the abnormal state most of the at least one operation variable based on the contribution. Therefore, provided are a method for verifying abnormal operation procedures of a nuclear power plant and a performing system thereof, wherein alarms and symptoms for monitoring the abnormal state of a nuclear power plant can be derived based on a simulator and artificial intelligence.
시뮬레이터를 이용하여 비정상 운전 시나리오를 모의함으로써 원자력발전소의 비정상 상태와 연관된 적어도 하나의 운전변수를 취득하는 단계와, 인공신경망이 원자력발전소의 비정상 상태를 판단할 수 있도록, 상기 적어도 하나의 운전변수를 이용하여 상기 인공신경망을 학습시키는 단계와, 상기 인공신경망의 학습 결과를 역산하여 상기 적어도 하나의 운전변수의 기여도를 계산하는 단계와, 그리고 상기 기여도에 기초하여 상기 적어도 하나의 운전변수 중 상기 비정상 상태의 판단 시 가장 큰 영향을 주는 운전변수를 도출하는 단계를 포함하는, 원자력발전소의 비정상 운전 절차서 검증 방법 및 이를 수행하는 시스템이 제공된다. |
