Abstract

Abstract: Civil opening sealing is an important work during the construction stage of nuclear power projects, which directly affects the follow-up nuclear cleaning and system transferred to commissioning. The sealing of biological shielding openings mainly exists in the walls and floors across the boundary of the nuclear island buildings, which is with great significance to ensure the integrity of the boundary function of the radiation zone. The configurations for openings in concrete shield walls shall provide adequate attenuation to reduce the exposure of the workers. Through the research of the biological sealing for civil opening and the investigation of good practice for foreign nuclear facilities, the purpose of this paper is to optimize the opening sealing scheme based on construction and operation experience, and give the guidance for the construction application and save the cost for the nuclear project.
