!- I (1) Model No.: 10-142A a (2) D6scription g

9, A steel encased, lead shielded cask for solid radioactiva material. The overall y h dimensions of the cask are 101-inch diameter by 120-inch height. The cask g

% consists of two concentric carben steel cylindrical shells surrounding a 3-1/2- 4 N

i inch thick lead shield. The 1/2 inch thick inner shell has a 66-inch ID, and the d N

l 1-inch thick outer shell has a 76-1/4-inch OD; the base consists of two,3-inch 4 hl thick welded steel plates. The base is welded to the steel cylindrical shells. A E stepped welded lid, secured by eight ratchet binders, is comprised of two,3-g!

g inch thick steel plates containing openings for a secondary lid of similar g sf construction with an additional 1-inch thick upper plate. The secondary lid is q kj secured to the primary lid through eight,1-inch diameter bolts. The g B. containment cavity is 66 inches in diameter by 72 inches high. The package g

> design is provided with a lid test port. Toroidalimpact limiters are located at 5l j the top and bottom of the cask. The impact limiters are 10-gauge stainless E

4 h steel filled with rigid polyurethane foam. Interior and exterior surfaces of the 5 h cask body and interior surfaces of the upper lid are covered with 12-gauge,304 g stainless steel cladding and seal welded, g

B; a

p The primary lid is closed by means of eight ratchet binders. The 29-inch g B diameter secondary lid is closed by eight,1-inch diemeter stud bolts. Both lids g 5 are sealed using silicone gaskets bonded to the lid plates. Lifting is facilitated W

$l with three lugs welded to the primary lid. The secondary lid has a redundant E Neoprene seal, and a centrally located lift lug.

p All exposed side walls are covered with a stainless steel thermal barrier. Four y

pl skewed lugs, welded to the outer shell, are used for tie-down. The package 4

B; gross weight is approximately 64,000 pounds. g

' By letter dated December 1,1998, ATG Nuclear Services L.L.C., and Molten Metal Technology, Inc., requested that the certificate holder for Certificate of Compliance No. 9073 for the Model  !

No.10-142A package be changed from Molten Meta! Technology, Inc., to ATG Nuclear i Services L.LC. ATG Nuclear Services L.L.C. has accepted responsibility for the completeness  ;

and accuracy of the statements and representations of the previous certificate holder. ATG i Nuclear Services L.L.C. will be responsible for maintenance of the certificate, the safety i analysis report for the package design, and the quality assurance records in accordance with l 10 CFR 671.91(c). ATG Nuclear Services L.L.C. has been issued Quality Assurance Program Approval for Radioactive Material Packages No. 0870, under Subpart H of 10 CFR Part 71.

l The Certificate has been revised to show ATG Nuclear Services L.L.C., as certificate holder.
