Description
図1は、実施形態1に係る冷却装置を備えた原子力設備を模式的に表した概略構成図である。図1に示す原子力設備1は、原子炉5として、例えば、加圧水型原子炉(PWR:Pressurized Water Reactor)が用いられている。この加圧水型の原子炉5を用いた原子力設備1は、原子炉5を含む一次冷却系3と、一次冷却系3と熱交換する二次冷却系4とで構成されており、一次冷却系3には、冷却水としての一次冷却水が流通し、二次冷却系4には、冷却水としての二次冷却水が流通する。
次に、本発明の実施形態2について、図面を基に説明する。図8は、実施形態2に係る冷却装置40aの一例を示す模式図である。図9は、実施形態2に係る冷却装置40aの一例を示す正面図である。図10は、実施形態2に係る冷却装置40aのA−A断面図である。図11は、実施形態2に係る冷却装置40aのA−A断面図である。実施形態2に係る冷却装置40aは、複数の空気冷却器50a、50bを有し、送風機51a、51bの空気流上流に互いに連結する空間104を有する点で、実施形態1に係る冷却装置40と相違する。その他の構成は、実施形態1と同じであるため、説明を省略する。
