| 摘要 |
The present invention relates to methods, structures apparatus and systems for preventing the airborne release of radioactive gases and particles and of radioactive and toxic liquids from a Nuclear Power Plant whose containment building (14) has failed during a (non-design basis) accident, (e.g. during a partial or complete core meltdown). The invention is inherently integrated with an overflow radioactive liquid storage system that simultaneously provides a hermetically sealed reservoir surrounding the reactor for containing and storing toxic and radioactive liquids which might accumulate during a reactor accident. In a preferred embodiment of the invention an inflatable dome design including a multiplicity of increasingly larger concentric domes (1, 2, 3, 4) are sealed to the ground or to the top of a subway ground system (5, 6, 7, 8). The spaces (10, 11, 12, 13) defined between the domes (1, 2, 3, 4) are connected to a control air filtration system. |
