j Steel encased, lead shielded cask for low specific activity material. L The cask is a right circular cylinder 81-1/2 inches high by 81-1/2 -

inches,in diameter. :The cask cavity is 73-3/8 inches high by 75-1/2 [

inches in diameter. The cask side wall consists of a 3/8-inch thick 3 inner steel shell, a 1-3/4-inch lead shell, and a 7/8-inch thick *

- outer steel shell . The base is compr'ised of two, 2-inch thick steel e plates welded together to -form a 4-inch thick base which is i

= integrally weldeo to_ the -inner and outer steeli shells of the side >

wall. A steel- flange is welded to the inner and outer steel shells

.of the side wall at the top. The lid is comprised of two, 2-inch thick steel plates, which are stepped and welded together to mate-with the ' steel flange. 3 The cask closure -is sealed by a Neoprene gasket located between the lid and steel flange, positive closure of the lid is accomplished by eight,1-3/4 inch ratchet binders. The lid.contains a' centrally located shield plug comprised of two, 2-inch thick steel plates and one,1-inch thick-steel plate stepped and L welded. The shield plug-is sealed by a Neoprene gasket, and eight,

3/4-inch studs and nuts are used to provide positive closure. 'The packaging is constructed of A-516, Grade 70, carbon steel. The outer shell1has a minim 9n yield strength of 46,000' psi. Tie-down is accon,nlished by four tie-down lugs welded to the cask body. There ,
