Abstract:

The report presents the results of studies conducted on various designs for a blast-closure device. The device is actuated by a signal from any one of several photocells located to receive light energy from a nuclear explosion. The photocell signal fires a squib in an explosive valve connected to a compressed-gas storage bottle. Releasing the stored energy in the compressed gas actuates a pneumatic cylinder connected to the closure bonnet and pulls the bonnet tight against its O-ring gasket to provide sealing against the positive and negative pressure phases of the blast wave. When the bonnet has reached its closed position, four spring-loaded latches engage striker pins on the bonnet and lock it closed until a later manual release is accomplished.
