[en] The Nuclear Weapons Effects Branch at White Sands Missile Range has proposed a storage vault for components of their fast pulse reactor. The reactor consists of eight stacked annular rings, a central safety block, and three rods of fully enriched uranium alloyed with ten weight percent molybdenum (rho = 17 gm/cc). The nominal mass per ring is 12.9 kg with inner and outer diameters of 10.16 and 20.32 cm. Rod and bolt holes penetrate through the eight ring stack. The design basis vault configuration consists of a 3 wide by 8 high planar array of reactor ring elements plus an assembled 8 ring stack on the reactor stand 45.7 cm in front of the array. The cubical unit cell dimension for the storage array is 30.48 cm. Vault materials are Portland concrete for the walls, ceiling and floor and Benelex 70 (Masonite) for the door
