원자력 발전소 습식 냉각탑의 기하형상이 구조거동에 미치는 영향에 관한 연구

Abstract

Since the use of seawater for the cooling system in the domestic nuclear power plant influences on ecological system of the coast, developed countries use the cooling system by natural draught cooling towers. Due to the enormous scale and sensible characteristics of the structure against thermal and wind load, the maintenance and the repair of the structural damage, besides structural safety, cause enormous costs. Therefore the durability design of the cooling tower becomes a new issue. In this study, the variables considered in the design of the cooling tower to the height of the effect through the analysis of the curvature is to propose an optimized method. Each of the analysis model based on parameters such as angle at base lintel and height of throat of the selected 25 prototypes and this trend was estimated by the natural frequency. To optimize the shell geometry by changing the angle at base lintel to the limit of 5 was chosen geometry, and it was evaluated by linear analysis.
