q! Steel encased,' lead shielded ' casks 'for solid radioactive material. l ll The overall dimensions of the casks are 101-inch diameter by 120-inch I li height. The casks consists of two ~ concentric carbon steel cylindrical I f shells surrounding a 3-1/2-inch thick lead shield. The 1/2-inch thick f
( inner shell _ has a 66-inch 10,' and the 1- or 1-1/8-inch thick outer L g; shell has a~ 76-1/4-inch OD;' the base consists of two,~ 3-inch thick [
I; welded steel plates of 66- and 74-inch diameters. The base is either i I welded to the steel cylindrical shells or sealed and held by ratch'e t I f, binders. A stepped welded lid, secured by eight ratchet binders or f g! eight studs and nuts, is comprised of two, 3-inch thick steel plates y containing openings for secondary lids of similar construction with at n least one additional 1-inch thick upper plate. The containment cavity
((l P
l is 66 inches in diameter by 72 inches high. A plugged drain port is i li located at the cask bottom. The Model No. NUS10-135 package design i I is provided with a . lid test port in lieu of a cask drain line. Toroidal I g
ltl impact limiters are located at the top and bottom of the cask. The g g impact limiters are 10-gauge steel sheets filled with rigid polyurethane, t i and are equipped with fusible plastic plugs. As an option, interior i I and exterior surfaces of the cask body and interior surfaces of the I 1
3 upper lid may be covered with 12-gauge 304 stainless steel cladding I li and seal welded. I lj l I- I
- There are four alternate lid closure designs for the Model No. 0H-142 n. '

\...../ Transportation Certification Branch Approval Record flodel Nos. OH-142 Series and NUS10-135 Packages Docket No. 71-9073 By application dated September 6,1985, Nuclear Packaging, Inc. requested several changes to the Safety Analysis Report and Drawings for the flodel No. 0H-142 Series packages to make them consistent with as-built packaging.
Liquid penetrant inspection has also been included as an option to magnetic particle inspection for the cask welds.
The changes do not have a significant effect on the ability of the package to meet the requirements of 10 CFR Part 71.
