High-temperature tritium scrubbing

[sevenperforce]

If you could design a fusion-based nuclear reactor with the potential to completely revolutionize energy access around the world, but the reactor could only function by releasing environmentally significant amounts of superheated tritium directly into the atmosphere, would there be any way to deal with it?

I am wondering if there is some compound which could be added to the vent stream to bind with the tritium and keep it out of the bio-cycle long enough for it to decay.

If tritium is in the vent stream, it will enter the biosphere if the system is operated in the biosphere. If the vent stream contains oxygen, the tritium, like protium, will tend to bind with the oxygen, either forming a hydroxyl ion or water, which may combine with other elements to form hydroxides or hydrated compounds.
