Model Nos.: HN-190-2 (2)

Description l

't Steel encased, lead shielded cask for radioactive material.

The cask is a N

right circular cylinder 81-1/2 inches high by 81-3/4 inches in diameter, The I

• I cask cavity is 73-3/8 inches high by 75-1/2 inches in dianeter.

The cask I

side walls consist of a 3/8-inch thick inner steel shell, a 1-3/4-inch lead W

shell, and a 7/8-inch thick outer steel shell.

Each base is comprised of 4

two, 2-inch thick steel plates welded together to form a 4-inch thick base I

h which is integrally welded to th inner and outer steel shells of the side I

h wall. A steel flange is welded to the inner and outer steel shells of the I

'h side wall at the top.

The lid is comprised of two, 2-inch thick steel plates N

I which are stepped and welded together to mate with the steel flange. The E

'I t.ask closures are sealed by a Neoprene gasket located between the lid and I

• t steel flange, positive closure of the lid is accomplished by eight rachet E

binders.

The lid contains a centrally located shield plug cotrprised of two, E

h 2-inch thick steel plates and one,1-inch thick steel plate stepped and u

'i welded. The shield plug is sealed by a Neoprene gasket, and eight, 3/4-inch I

h studs and nuts are used to provide positive closure, q

Tie-down is accomplished by four tie-down lugs welded to the cask body.

4 There are four cask lifting lugs, three lid lifting lugs, and one shiel' plug a

lifting lug. The package gross weight is approximately 48,000 pounds.

(a) for any package containing water and/or organic substances which could u

g radiolytically generate combustible gases, determination must be made by a

tests and measurements or by analysis of a representative package such that a

t the following criteria are met over a period of time that is twice the g

$l

+

expected shipment time:

a' d

e' (1) The hydrogen generated must be limited to a molar quantity that would be g

p' no mort than 5% by volume (or equivalent limits for other inflammable y

n' gases) of the secondary coptainer gas void if present at STP (i.e., no a

pl more than 0.063 g-moles /ft at 14.7 psia and 70'F); or g

E (2) The secondary container and cask cavity must be inerted with a diluent to g

p g

assure that oxygen must be limited to 5% by volume in those portions of g

l g

the package which could have hydrogen greater than 5%.

g l

For any package delivered to a carrier for transport, the secondary container l

,I must be prepared for shipment in the same manner in which determination for g

,1 gas generation is made. Shipment seriod begins when the package is prepared y

q (sealed) and must be completed wit 1in twice the expected shipment time.

8 I

(b)

For any package shipped within 10 days of preparation, or within 10 days U

after venting of drums or other secondary containers, the determination in

,1 (a) above need not be made, and the time restriction in (a) above does not f

I

apply, g

8 f7.

Except for close fitting contents, shoring must be placed between secondary N

,i containers and the cask cavity to prevent movement during normal conditions of transport.

l qll8.

The lid and the shield plug lifting lugs must not be used for lifting the cask, and 8

(

,i must be covered in transit.

i 9.

In addition to the requirements of Subpart G of 10 CFR Part 71:

(a)

Prior to each shipment, the packaging lid seals if opened (or if security E;

• i seal is broken), must be inspected. The seals must se replaced with new I

h seals if inspection shows any defects or every twelve (12) months, which ever W

h occur first.

Cavity drain line and optional vent / test connection must be N

h sealed with appropriate sealant applied to the pipe plug threads.
