In transport and storage of nuclear fuel rod applications of ideal device and this device

摘要

(57) Abstract It has the basket which possesses the plural storage cells which were formed with the honeycomb lattice body structure of the plural metal plates of rectilinear form, each plate is welded mutually in the mutual intersection section, in order to allow the movement all angular corner sections of each storage cell which is formed because of this by the aforementioned lattice body structure with the conduction of heat, extending to total length, is connected, furthermore the used nuclear fuel rod transport and storage which feature that it has possessed the neutron absorber in the region where the aforementioned metal plate forms the wall surface of each storage cell device. Being production method of the used nuclear fuel rod transport and storage device, as a) it possesses the plural slots, process and b which prepare the metal plate which at the same time possesses the neutron absorber on the surface) making the aforementioned slot cross, it possesses the plural contiguity angular corner sections, connecting all contiguity angular corner sections of the storage cell which is formed by process, and c) aforementioned lattice body structure which form the honeycomb lattice body structure of the plural storage cells which possess the aforementioned neutron absorber in the side completely, as it allows the transmission with the conduction of heat way it gives rigid structure, each metal plate each otherThe method of featuring that the process which welds mutually in the intersection section is had.
