Abstract

PURPOSE:To improve the flow of a coolant and reliability by providing outflow holes for flowing out of the coolant to the upper position on the side faces of protective pipes and providing pads which can close the outflow holes of the adjacent protective pipes near the outflow holes. CONSTITUTION:The outflow holes 30 from which the coolant flows out are provided on the upper position on the side faces of the protective pipes 2 and the pads 31 which can close the outflow holes 30 of the adjacent protective pipes 2 are provided. The outflow holes 30 and the pads 31 preferably exist in the height position of the upper blankets in the axial direction of the fuel rods housed in the fuel assemblies. The coolant flows the fuel assemblies from the inflow ports of entrance nozzles, passes between the fuel rods and goes toward the outflows ports 30 of the protective pipes 2 when the fuel assemblies are pulled up into the coolant from the reactor core part at the time of exchanging the fuel of the fuel assemblies. The coolant liquid level can, therefore, be lowered. The pads 31 close the outflow holes 30 of the adjacent protective pipes 2 at the time of operation of a nuclear reactor and, therefore, the nonuniformization of the flow of the coolant during the operation is obviated; further, the pads 31 have the function to hold the fuel assemblies to each other and, therefore, the oscillation by flow between the fuel assemblies is suppressed.
