Zusammenfassung:	The present invention relates to an in-service inspection apparatus for a passive autocatalytic recombiner capable of periodically checking the removal performance of hydrogen for a catalyst used for the passive autocatalytic recombiner (PAR) for combining oxygen and the hydrogen generated during the operation of a nuclear power plant and converting the oxygen and hydrogen into vapor. For solving the problem, the in-service inspection apparatus for a passive autocatalytic recombiner according to the present invention can check the hydrogen removal efficiency of the catalyst by using a hydrogen analyzer to detect the concentration of the hydrogen by the catalyst before reaction and the concentration of the hydrogen after reaction by the catalyst, respectively. 본 발명은 원자력 발전소의 운전 중에 발생되는 수소를 산소와 결합시켜서 수증기로 변환시키는 피동형 자동촉매 재결합기(PAR)에 사용되는 촉매체에 대한 수소 제거 성능을 주기적으로 확인할 수 있는 피동형 자동촉매 재결합기용 가동중 검사장비에 관한 것이다. 상기 과제를 해결하기 위하여 본 발명에 따른 피동형 자동촉매 재결합기용 가동중 검사장비는, 촉매체에 의한 반응 전 수소 농도와 반응 후 수소 농도를 각각 검출하는 수소 분석기를 이용하여 상기 촉매체의 수소제거효율을 확인할 수 있는 것을 특징으로 한다.
