(a)

Packaging (1) Model No.: TN-8 (2) Description A lead, steel and resin shielded irradiated fuel shipping cask. The cask approximates a right circular cylinder 1,718 m in diameter and 5,516 mm long.

The cavity consists of three (3) stainless steel square pressure vessels welded to an end plate and a circular stepped top flange, separated by a T-shaped copper plat'e and surrounded with B4C + Cu plates.

Each cavity is 230 x 230 mm and 4,280 mm long. The main shielding consists of 135 mm of lead, 26 m of steel and 150 mm of resin. A wet cement layer is located between the lead and the outer shell. Radial copper 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 press'ure vessels are 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 innter cavity are equipped with positive closures.

In addition, all access ports are protected by the impact limiters.
