description The present invention relates to a device for determining validity of a measured value of a measuring device showing an accident situation of a nuclear power plant when a severe accident occurs in the nuclear power plant. The device comprises: a sensing unit for receiving a measured value sensed from at least one first measuring device included in a specific region or a specific system of a nuclear power plant; a physical model-based evaluating unit including a physical model imitating physical constitutional factors corresponding to the specific region or specific system; an environment influence evaluating unit for inspecting validity of the measured value in accordance with at least one predetermined inspection logic; and a control unit for determining validity of the measured value on the basis of a measured value sensed by a second measuring device disposed in the physical model and the at least one inspection logic in accordance with the presence of a physical model corresponding to the specific region or specific system. 본 발명은 원자력 발전소에서 중대 사고 발생시 원자력 발전소의 사고 상황을 나타내는 계측기의 계측값 유효 여부를 판단하기 위한 것으로, 원자력 발전소의 특정 영역 또는 특정 계통에 포함된 적어도 하나의 제1 계측기로부터 감지된 계측값을 수신하는 감지부와, 상기 특정 영역 또는 특정 계통에 대응되는 물리적 구성 요소들을 모사한 물리 모델을 포함하는 물리 모델 기반 평가부와, 기 설정된 적어도 하나의 검증 논리에 따라 상기 계측값의 유효성을 검증하는 환경 영향 평가부와, 및, 상기 특정 영역 또는 특정 계통에 대응되는 물리 모델이 있는지 여부에 따라, 상기 물리 모델에 구비된 제2 계측기에서 감지된 계측값과 상기 적어도 하나의 검증 논리 중 적어도 하나에 근거하여 상기 계측값의 유효 여부를 판단하는 제어부를 포함하는 것을 특징으로 한다.
