Packaging (1) Model No.:
SENTINEL 8S (2) Description The packaging contains a thermoelectric generator with 55,000 Ci of strontium 90 titanate or strontium 90 fluoride.
The dimensions are 32.2 inches in height by 37.53 inches in diameter. The package is welded to a 39.5-inch square, stee's pallet, which is 4 inches high.
The contents are housed in a stainless steel or Hastelloy C-276 liner.
The liner, with its pressed cap, is contained within a fuel capsule (5.5" x 3.735" 00). The capsule lid is threaded for strength and welded (minimum weld penetration of 0.055" is specified) to give a positive seal. The wall thickness of the capsule is a minimum of 0.3475 inch. The fuel capsule is constructed of Hastelloy C-276 (or Uniloy HC). The capsule is inserted into the tungsten biological shield (8.367" x 6.467" 00), and the shield plug is bolted into place using three steel bolts, equally spaced on a 5.093-inch bolt circle.
I The tungsten shield is held in a horizontal position within the gener.ator's l
aluminum housing by the sized Min-K-1301 thermal insulation. Min-K and load bearing Glasrock are used to support the shield base. A retaining ring is used to preload the Min-K and to dampen any vibrational loads.

a Paga 2'- Certificate No. 9085 - Revision No. 2 - Docket No. 71-9085 (2) Description (continued)
The finned 6061-T6 aluminum housing forms the outer protective shell
~ f the generator. During shipment, the detachable fin extensions will o
be bolted to the fins. This increases the fin diameter from 22 inches to 26 inches, holding the generator securely in the shipping cask body (5.68" min. wall thickness, ASTM A-181 grade 2 forgad steel).
The interface between the overlapping fin surfaces is coated with a heat transfer compound (DOW Corning 340). The total system weight is approximately 7,400 pounds.
(3) Drawings The principal features of the package are shown in the drawings contained in the Teledyne Energy Systems application, dated March 3, 1977.
(b)
Contents (1) Type and form of material (i) Strontium 90 titanate doubly encapsulated in a stainless steel liner and Haste 11oy or Uniloy HC capsule which meet the require-ments of special form as defined in 10 CFR 571.4(o).
(ii)
Strontium fluoride (90SrF ) doubly encapsulated in a Haste 11oy or 2
Uniloy fuel capsule, with a Haste 11oy C-276 liner which meets the requirements of special fonn as defined in 10 CFR 571.4(o).
(2) Maximum quantity of material per package 55,000 curies.
