method and system to contain the effects of failures in nuclear power plants mainly due to the loss of heat from the first circuit for vehicle

摘要

The pressure vessel of the reactor with all primary working fluid cooling system components is enclosed in a first sealed chamber communicating via a condenser assembly with a large buffer chamber filled initially with cold air. In the event of a burst vapour evolved from the leaking primary coolant passes through the condenser which has cooling agent injectors in a closed circuit, into the buffer chamber which has controlled venting of the resultant weakly radioactive air-vapour mixt.
