Abstract
A method of making a rack for storing a maximum number of fuel assemblies in spent-fuel storage locations in a minimum space. The rack has locations each formed by bending a stainless-steel sheet into a hollow body of the generally rectangular cross section and with each side shaped so that the apices of the body project outwardly. Except for bodies along the outer periphery of the rack, the apex of each body is contiguous to the apex of an adjacent body. These contiguous apices are joined by spaced welds longitudinally along the bodies. The welds are spaced so as to maximize the resistance of the rack to seismic acceleration and spent-fuel storage locations are thus formed. Four storage locations extend radially from the apices of each location. A wrapper plate is secured to each side of each of these four locations providing a pocket for neutron-absorbing material. An additional storage location is formed having pockets in common with the locations which bound it.
