Abstract
The vertical tubes of the storage rack are spaced apart by spacer strips which are welded to the tubes and which define seal-tight chambers which are filled with neutron-absorbing material. Individual covers are used to close each chamber and to permit ready access to the chambers for changing the neutron-absorbing materials. The spacer strips may be in the form of flat strips, angle strips, cruciform strips and bars. Each tube may also be made of a pair of angle plates which are welded to the base plate of the rack.
