Continuous collecting system for radiocarbon from stack in PWR nuclear power plant's

摘要

PURPOSE: A device for continuously collecting radiocarbon exhausted from a nuclear power plant is provided to accurately measure and analyze the density and amount of radioactivity by continuously collecting the gas sample exhausted from a nuclear power plant according to a chemical type. CONSTITUTION: A flow controller(11) controls the flow rate of a gas sample exhausted from an exhaust pipe of a nuclear power plant to the external environment. A tritium removal aeration bottle(12) is a GWC(Gas Washing Column) and removes tritium contained in the exhausted gas sample. The tritium removal aeration bottle is filled with deionized water to prevent the evaporation of NaOH that is a collecting solution. A catalytic reaction controller(15) is comprised of a flow meter, a digital timer, a temperature program controller, and a breaker. A continuous collecting device(10) includes a catalytic reactor(14). An organic type radiocarbon is collected in the collection aeration bottle via the catalytic reactor.
