Heat removal from irradiated fuel element store - by natural convection between internal and external exchangers esp. via heat pipe

摘要

Nuclear plant comprises buildings in which heat is generated, esp. as decay heat from used fuel elements. To remove heat from the building or buildings, a heat transfer system (3) connecting the inside of the building to the exterior is provided. Each heat transfer system (3) is a closed circuit partly filled with a vapourizing medium and having two heat exchangers (3a,3b) one inside the building and one outside. T he heat exchanger.
