Description

{Exhaust Gas Treatment Plant for Building Nuclear Reactor}

The present invention relates to a nuclear power plant building exhaust treatment facility capable of efficiently removing tritium from air discharged from the inside of a building of a heavy water reactor type nuclear power plant and preventing environmental pollution caused by radioactive elements emitted to the atmosphere.

Generally, pressurized heavy water reactor type nuclear power plants use heavy water (D2O) as a coolant and a moderator for operation of a reactor. However, during the operation of the reactor, part of the heavy water is converted to tritium (T or 3H) by combining with neutrons to generate radioactivity. The concentration of the radioactivity increases with the service life of the power plant. Tritium is one of the hydrogen isotopes, an artificial radioactive element with a mass of three, consisting of one proton and two neutrons.

This tritium is not only the heaviest of isotopes of hydrogen but also causes beta decay (β decay) and radioactive element with a half life of 12.3 years, which causes radioactive contamination in mass use.

On the other hand, the heavy water leaks from a pipe or a seal part of the pump through evaporation. At this time, the tritium also leaks to exist in the form of vapor (moisture) in the air.
