Process system and layout design of high level radioactive liquid waste storage building

Abstract: The high level radioactive liquid waste (HLLW) storage building is an essential facility in the spent fuel reprocessing plant. and its stable operation is related to the production safety of the entire plant area. This article elaborates on the process system design of HLLW storage building based on design standards and engineering practice. including the HLLW storage and transportation system. circulating cooling water system. HLLW mixing system. dilution air and exhaust treatment system of the liquid waste storage tank. and so on. The overall layout form. process equipment and pipeline layout characteristics of HLLW storage building are introduced with the example of the actual project. Reference can be provided for designing of HLLW storage building and other nuclear chemical projects in the future.
