논문은 NuSCR 정형 명세 언어로 작성된 소프트웨어 요구 명세로부터 소프트웨어 고장 수목을 생성하는 방법에 대하여 제안하였다. 본 연구에서 제안하는 소프트웨어 고장 수목은 소프트웨어의 구조와 동작에 대한 요구 사항을 반영하는 통합된 형태의 고장 수목으로, 안전성에 대한 복합적인 분석이 가능하다. 이러한 소프트웨어 고장 수목을 생성하기 위하여 NuSCR 정형 명세언어의 구성 요소 각각에 대한 템플릿을 정의하고, 이들 템플릿을 사용하여 소프트웨어 고장 수목을 생성하는 방법을 제안하였다. 그리고, 제안된 방법의 유용성을 평가하기 위해 현재 국내 원전계측제어시스템 개발사업단에서 개발 중인 차세대 원자력 시스템 APR1400에 사용될 원자로 보호 시스템의 핵심 트립 논리에 대하여 고장 수목을 생성하고 분석 하였다.
