(2) Description E

g j

The packaging contains a thermoelectric generator with 32,900 ci of strontium 90 fluoride meeting the requirements of special fonn radio-2 active material.

i E

The double encapsulated fuel is held in,ide a depleted uranium biological N

shield (7.3-inch OD x.8.85-inch) which is provided with a stepped plug g

lid and secured with 6,1/4-inch x 1.25-inch long steel bolts.

The depleted uranium shield is held in position within the generator's aluminum housing by sized Min-K thermal insulation. A retaining ring g

is used to preload the Min-K and to dampen any vibrational loads.

g E

During shipment, the finned aluminum housing of the thermoelectric

(@

generator is contained within an inner shipping container which is provided with stepped lid and secured with 12, 3/4-inch steel bolts

('

which are recessed. flovement of the generator is restricted by an RTG Preload Assembly within the, inner vessel.

The inner container is constructed of ASTM A-181 forged steel and a lid fabricated of A-36

[

s teel.

The inner container dimensions are 26.1-inch ID x 21.7-inch H

c high x 36.53-inch OD x 32.2-inch high plus 2-inch thick aluminum h

bumper pad (spacer) located on the top lid.

[

The outer shipping container is fabricated from 3/8-inch thick 304L l

stainless steel (SS) with a 3/4-inch thick bottom plate. The top lid is joined to the bottom of the outer container by 12, 3/4-inch steel bolts and nuts through 2, 3/4-inch thick SS flanges. The closure flanges are gasketed to preclude entry of rain water. The outer l

package is reinforced by 4, 3/8-inch thick SS stiffener ribs (external).

l The lid stiffener ribs contain 4, 2-1/8-inch diameter lifting / tie-down p

holes. The bottom plate is welded to 2, 4-inch I-beams.

The gross weight of the package is 8,460 pounds which includes the N

276-pound weight of the thennoelectric generator.
