CONTAINMENT BUILDING AIR POLLUTION PREVENTING APPARATUS

摘要

PURPOSE: A containment building air pollution preventing apparatus is provided to be capable of minimizing an air pollution of a containment building due to a discharged fluid when unnecessarily opening a safety pressure valve at an excess state of a nuclear power station. CONSTITUTION: A safety pressure system consists of two pipes for forming discharge paths of a containment building from a pressurizer(100). Respective discharge paths comprise a pair of continuous gate(110,111) and glow valves(111,121), respectively. A common pipe(140) is installed to interconnect discharge paths being ends of the respective pipes. The safety pressure system is configured to connect a discharge pipe(150) into a safety pressure tank(200), and the discharge pipe(150) is connected to the common pipe(140).
