Description

Object: To prevent failure of fuel rods resulting from trouble of coolant loss without modification of basical construction of a cooling device in a low pressure water injection system. Structure: To provide an opening having a sectional area which is 10 to 20% of that of a cooling water passage, at a position lower than an upper tie plate on the wall surface of a channel box enclosing therein fuel rods but at a position higher than an effectively heat-generating upper end of the fuel rods. With this arrangement, flow of spray water into the fuel assembly and resultant impeding phenomenon or the like can be avoided. (Kamimura, M.)
