l Steel encased, leao shielded casks for solid radioactive material.  !

q; The overall dimensions of the casks are 101-inch dianeter by 120-inch <

qj height. Thecasksconsistsoftwoconcentriccarbonsteelcylindricall I! shells surrounding a 3-1/2-inch thick lead shield. The 1/2-inch thicki N

inner shell has a 66-inch ID, and the 1- or 1-1/8-inch thick outer '

fr shell has a 76-1/4-inch OD; the base consists of two, 3-inch thick i f

welded steel plates of 66- and 74-inch diameters. The base is either g!

g welded to tht steel cylindrical shells or sealed ano held by ratchet N' binders. A stepped welded lid, secured by eight ratchet binders or ;j ll I

eight studs and nuts, is comprised of two, 3-inch thick steel plates i' I

containing openings for secondary lids of similar construction with at i least one additional 1-inch thick upper plate. Thecontainmentcavityl is 66 inches in diameter by 72 inches high. A plugged drain port is l .

i located at the cask bottom. The Model No. LN-142 package design l' 1, is provided with a lid test port in lieu of a cask drain line.

Toroidal impact limiters are locatcd :t the top and bottom of tne cask.!

Closure of the primary lid is accomplished I by eight ratchet binders; and of the 24-inch (29-inch) secondary lid l by eight, 7/8-inch (1-inch) diameter stud bolts. Both lids are sealed i using silicone gaskets bonded to th! lid plates. Lifting is i facilitated with three lugs welded to the primary lid. The secondary f 'id has a redundant Neoprene seal, and a centrally located lift lug.

d I Mark l closure design. Closure of the primary lid is accomplished by l eight ratchet binders, and a bondad silicone gasket provides the ,

i primary seal. Lifting is facili'.ated with three lugs welded to the l l primary lid. Six,19-inch (or cc ,16-inch, centered) diameter l l secondary lids with centers located on a 44-inch circle each have s'x, i I 3/4-inch diameter hex head' bolts. They esch have a primary bonded '

! silicone seal, a redundant Neoprene seal, and a centrally located lift l lug. l An alternate Mark 1 configuration utilizes eight, 1-3/8-inch studs and f nuts for primary lid closure and two lifting lugs on the primary lid.

4 i Mark 2 closure design. Closure of the primary lids located at the t9p :

[ and bottom of the cask is accomplished by eight ratchet binders, and a I g bonded silicone gasket on each primary lid provides a seal. Li f ting l g is facilitated with three lugs welded to the upper primary lid. The  !

'4 upper lid contains a centrally located 24-inch (or 29-inch) diameter  !

4i seconaary lid comprised of two stepped and welded 3-inch steel plates l 4! above and below a 1-inch steel plate. Closure of the secondary lid is provided by eight, 7/8-inch (or 1-inch) diameter stud bolts. The l secondary lid has a bonded silicone seal, a redundant Neoprene seal g

y and three lift lugs.

4 p The Model No. LN-142 cask is nearly identical to the baseline j Model No. OH-142 cask with a 29-il.ch diameter secondary lid.

4 f All exposed side walls are coated with an intumescent material or covered with a stainless steel thermal barrier. Four skewed lugs,

.! welded to the outer shell 6re used for tie-down. The package gross i weight is approximately 64,000 pounds.

Transportation Branch j Approval Record i Model Nos. OH-142 Series and LN-142 Packages

_ Docket No. 71-9073 Pevision No. 16 l i

i By application dated June 1, 1987, as supplemented July 29,1987, LN Technologies Corporation requested the Model No. NUS10-135 packaging be revised to Model No. LN-142. On September 30, 1986, London Nuclear Services purchased all the outstanding stock of the NUS Process Services Corporation.

The two organizations merged into a new comptuy called LN Technologies Corporation. The Operating Procedures, Leak .ast Procedures, Maintenance Procedures, Gamma Scanning Procedures, and the cask drawings have been revised to reflect the name change and the change in model number.

LN Technologies also requested that the use of procedure WN-011 Soap Bubble Leak Test, be authorized in lieu of WM-023 Halogen Leak Test presently cited in the certificate. The soap bubble test is an acceptable method of checking ,

the containment system of a package whose contents are limited to low specific activity material in the type and, form cited by the certificate.

Condition 9 has been added to the certificate to cite the requirements of 10 i CFR 971.52 relative to the transport of low specific octivity material.  ;

There have been no changes to the package design. The requirements of 10 CFR Part 71, have been met.
