<p>This invention is designed to isolate and contain systems that are at risk from explosion or subsequent damage arising from an explosion, fire, hazard, or other calamity. Preferably, it acts as a preventative system in nuclear reactors to reduce the risk of damage, but the Emergency Roofing and Barrier System can also be used after an explosion or damage has occurred to bring the situation under control and to facilitate the system being made safe. In one basic embodiment, the system comprises a two-piece cap for a nuclear reactor vessel which, under normal operating conditions, allows the circulation of coolant between the two-pieces through vents in the cap. However, in the event of an explosion, the pressure within the reactor forces the two pieces together, thereby closing the vents and sealing the reactor vessel. Alternatively, it could be used as a barrier system to contain the spread of fires or explosions in mining and other hazardous situations.</p> |
