Abstract

The APR1400 is a 1400MWe nuclear power plant developed through national technology development project over a period about 10years. Approximately 65,000 design drawings are produced for APR1400 construction. In order to maintain consistency among numerous drawings, the highest level of design bases drawings (DBDs) are created according to design bases and this is used in the subsequent design. However, DBDs are produced and managed on a document basis and they are managed various field, it was difficult to accurately reflect the design bases information in the subsequent design. Therefore, this study recognizes limitations of the document based DBDs and develops a system that can accurately reflect the design bases information to subsequent design by adopting BIM based design bases integrated information system. Especially, by introducing DBIL(Design Bases Information Layer) concept, DBIL was created and analyzed based on five design bases(Physical protection, Fire protection, Internal missile protection, Internal flood protection, Radiation protection) applied to APR1400. In the final result DBIL set and Datasheet are integrated of room, design bases information, building data(wall, slab, door, window, penetrations). So it can be used for subsequent design automation and design verification. Furthermore, it is expected that APR1400 DBILs data can be used extensively in constructability and design economics analysis through comparison with next generation nuclear power plant.

APR1400은 1992년 12월부터 2001년 12월까지 약 10여년에 걸쳐 국가선도 기술개발과제를 통해 개발된 1,400MWe급 차세대 원자력발전소 노형으로, 건설을 위해서 약 6만 5천 장의 도면이 생산된다. 또한 수많은 도면 간 일치성 유지를 설계기준(Design Bases)에 따라 가장 높은 수준의 설계기준도면(Design Bases Drawing)를 작성하여 후속설계에 가이드라인 역할로 활용하고 있다. 하지만 설계기준도면이 문서기반으로 생산 관리되고 있고, 다양한 분야에서 파편적으로 운영되어 설계기준정보를 정확하게 인지하고 후속설계에 정확하게 반영하는데 어려움이 있었다. 따라서 본 연구는 문서기반의 설계기준도면의 한계를 인식하고, BIM 기반의 설계기준 통합관리 체계를 도입하여, 설계기준 정보를 체계적이고 정확하게 후속설계에 반영 할 수 있는 체계를 구축하였다. 특히 DBIL(설계기준정보층)개념을 도입하여 5가지 설계기준(물리적방호, 화재방호, 내부비산물방호, 내부침수방호, 방사선방호)을 적용하여 DBIL생성 및 속성을 분석하였다. 최종 결과물인 DBIL set와 Datasheet에는 실(Room), DBIL, 설계기준 속성, 빌딩 데이터(벽 바닥 슬라브, 문 창문, 수직 수평관통부)를 통합 추출하여 후속설계 자동화 및 설계검증에 활용할 수 있도록 하였다. 더 나아가 APR1400 DBIL에 적용되는 5가지 설계기준의 속성을 분석하여 후속호기 및 차세대 노형과의 비교를 통한 경제성 분석 등에 폭 넓게 활용할 수 있을 것이라 예상한다.
