- 4. CONDITIONS This certificate is conditional upon the fulfilling of the requirements of Subpart 0 of 10 CFR 71, as applicable, and the conditions specified in item 5 below.
S. Description of Pack ging and Authorized Contents, Model Numoer Fissile Class. Other Conditions, and Refs:saces:
(a) Packaging (1) Model No.: TN-9 (2) Description A lead, steel resin shielded irradiated fuel shipping cask. The cask approximates a right circular cylinder 1,718 mm in diameter and 5,756 mm long. The cavity consists of three rectangular, stainless steel pressure vessels welded to end plates and a circular stepped top flange and separated by thin cooper plates. The bays are divided into a total of seven (7) square compartments,150 x 150 mm and 4,520 mm long. The main shielding consists of 128 mm of lead, 26 mm of steel and 150 mm of resin. A wet cement layer is located between the lead and the outer shell.
Radial copper cooling fins are welded to the outer shell and cover the surface of the cask between each end drum.
The lid is a welded stainless steel shell containing(lead and resin shields.
The pressure vessel is closed and sealed by sixteen 16), 1-1/4-inch diameter bolts and two silicone rubber or Viton 0-rings located within recessed grooves on the top flange.
Each extremity of the cask is surrounded by circular stainless steel drums reinforced by radial gusset plates and filled with balsa wood. A disk shaped impact limiter, constructed of carbon steel and balsa wood, is fastened to each drum with four (4),
1-1/4-inch bolts. The vent and drain lines which penetrate the inner cavity are equipped with positive closures.
In addition, all access ports are protected by the impact limiters.

The package contents shall be so limited that under normal conditions of transport, the total dose rates shall not exceed 14 mrem /hr at 3 feet from the surface of the package.
- 10. Any system used for cooling down the package shall be provided with a pressure relief device set so that the maximum pressure in the containment vessel cannot exceed 7 atmospheres during the cool-down process.
11.
The systems and components of each packaging shall meet the periodic tests and criteria specified in Chapter VIII of +he Application.
Each packaging that fails to meet these criteria shall be withdrawn from service until corrective action has been completed.
