Development of foam plastic as high temperature insulation and shock absorbent lining for UF6 packages

Foam Plastic Insulation for High Temperature and Shock Protection

“…Identical samples of cork and vermiculite were tested in the dry ice slush simultaneously. From the resulting cooling rate data, the thermal insulating efficiency of the foam was found to be almost identical to cork at these low temperatures, and considerably better than vermiculite (4).…”

Foam Shock Absorbers for Lower I nlet Doors of Nuclear Reactor Ice Condenser Compartments- Design Considerations

“…A frangible phenolic foam shock absorber, capable of absorbing the kinetic energy from an impacting door, has been designed, built, and found satisfactory by full-scale testing. 2. A bag, fabricated from a fiberglasspolyethylene laminate to contain foam fragments during crushing, was designed, tested, and found satisfactory by full-scale testing.…”

“…Based on small-scale laboratory tests, three foam systems -two polyurethane and one phenolicwere identified as adequate to meet the energy absorption requirements. However, based on known radiation resistance (2), hydrolytic stability (3,4), ease of fabrication, open cell content, and full-scale test results, a 2.6 pcf phenolic foam was selected. Full-scale tests were conducted to verify concepts and laboratory experiments and to qualify the shock absorber.…”

A Mechanical Shock Absorber Made From Low Density Phenolic Foam. Part I-Material Selection

“…For our specific requirements, large buns, 10 ft3, were foamed and trimmed to the desired size and shape. These larger sizes result in labor costs savings when fabricating the 30 fe shock absorbers.…”
