Abstract
A rack for storing spent nuclear fuel elements in which a plurality of aligned rows of upright enclosures of generally square cross-sectional areas contain vertically disposed fuel elements. The enclosures are fixed at the lower ends thereof to a base. Pockets are formed between confronting walls of adjacent enclosures for receiving high absorption neutron absorbers, such as Boral, cadmium, borated stainless steel and the like for the closer spacing of spent fuel elements.
Claims17
A rack for spent nuclear fuel elements comprising:
- (a) a base;
- (b) a plurality of upstanding enclosures supported by said base for containing respectively a spent nuclear fuel element, adjacent enclosures being spaced apart to form vertically disposed pockets;
- (c) neutron absorbers disposed in said pockets for controlling nuclear reactivity;
- and
- (d) upstanding neutron absorber panels disposed exteriorly of said enclosures and along the outer limits of the rack for controlling nuclear reactivity from spent nuclear fuel elements stored in said enclosures.
