摘要
PURPOSE: A nuclear reactor loss of large coolant accident alleviating apparatus is provided to delay melting situation of each configuration members consisting of nuclear reactor assembly by effectively eliminating heat created in core. CONSTITUTION: A bottom lead(6b) is combined to a top lead(6a) to be possible to be folded. A second hinge part(8) combines the bottom lead and the top lead to be possible to be folded. A cover(6) is located in an adjacent portion of a low temperature pipe nozzle(3) and a core support barrel(2) in order to compulsorily guide a flow direction of a coolant. The cover opens or closes a cross section of the low temperature pipe nozzle. A cross section of the cover is formed into a same shape with the cross section of the low temperature pipe nozzle.
