Abstract

PURPOSE: TO secure the feeding of cooling water for emergency at the time of loss of coolant accident, by means of setting up a hood whose area in the uper part is smaller than that of the bottom opening, and in which introducing holes are set up at the sidewall, at the outlet part of the fuel assembly.
CONSTITUTION: A hood 6 whose area of the upper opening is smaller than that of the bottem part opening, is set up at the upper part of the fuel assembly composed of containing a plurality of fuel rods 1 supportted and fixed by an upper tie plate 2, a lower tie plate 3, and a spacer 4 within a wall 5 of the fuel element, and water introducing holes 9 are set up at the sidewall 6 for the purpose of injecting the water collected in a ring channel part 8 into the outer circumferent part of a little steam quantity in the fuel element. Water pouring holes 10 for allowing the cooling water collected beside of the fuel assembly to be flowed into the outer circumferent part of the fuel element are installed at the sidewall 5 of the fuel element in a little lower part than the upper plate 2
