Abstract: Cryogenic insulation system for containers for storage of cryogenic liquefied gases such as LNG, comprised of a low temperature resistant metal, preferably high nickel steel, primary membrane or liner supported by a primary layer of reinforced foam insulation, and a secondary liner positioned adjacent to and sandwiched between the primary layer of foam insulation and a secondary layer of reinforced foam insulation. The preferably high nickel steel primary liner or membrane is supported above the primary foam insulation layer by stiffened ends of the reinforcement fibers which extend above the surface of the foam insulation, providing a small gap between the foam and the membrane. There is provided at corners, particularly at 90.degree.

The preferably high nickel steel primary liner or membrane is attached to the primary layer of foam insulation by tongues of high nickel steel connected to the primary membrane at spaced positions therealong, and engaged in plywood retainers positioned within and bonded to the primary foam insulation layer. The plywood retainers for such tongues include spaces or channels in communication with a manifold for detection of cryogenic gas leakage. There is provided at corners, particularly at 90.degree.

Abstract: A shield for shielding against radiation from a nuclear blast. The shield comprised of an aluminum body structure, a tin sheet bonded to the outer surface of the aluminum body structure, a glass filament reinforced epoxy resin matrix composite plastic material wrapped about the tin material and an outer layer of external thermal ablative insulation. The glass filament wrapping of the tin material causes the tin material to act as an effective shielding material by maintaining integrity of the tin when exposed to radiation.
