i (2) ' Description 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 y

are four cask lifting lugs, three lid lifting lugs, and one shield plug lifting lug. -The package gross weight is approximately 53,000 L
