An extraction method of a high purity tritium gas from tritium-containing heavy water is disclosed. Tritium-containing heavy water is led from a heavy water source into an exchange reaction column wherein the heavy water is brought into contact with a tritium-containing heavy hydrogen to thereby transfer tritium in the heavy hydrogen into the heavy water by way of the exchange reaction to obtain a tritium-enriched heavy water. The resulting tritium-enriched heavy water is then led to a heavy hydrogen gas generator such as an electrolytic cell to generate a tritium-enriched heavy hydrogen, a part of which is recycled to the exchange reaction column and the remaining part thereof is led into a hot-wire type thermal diffusion column, e.g. cascade to enrich tritium. The thus enriched tritium gas is withdrawn from the thermal diffusion column cascade. The tritium-depleted heavy hydrogen withdrawn from the exchange reaction column is burnt to produce a tritium-depleted heavy water which is then recycled to both the heavy water source and the exchange reaction column.

A method of extracting tritium from tritium-containing heavy water which comprises: leading a part of the tritium-containing heavy water from a heavy water source to an exchange reaction column wherein the heavy water is brought into countercurrent contact with a tritium-containing heavy hydrogen to thereby transfer tritium in the heavy hydrogen into the heavy water by way of the exchange reaction; withdrawing the heavy water having an enriched tritium content from the bottom of said exchange reaction column and the heavy hydrogen having a reduced tritium content from the top of said exchange reaction column; leading the tritium-enriched heavy water to a heavy hydrogen gas generator to generate a tritium-enriched heavy hydrogen; recycling a part of the tritium-enriched heavy hydrogen to said exchange reaction column to carry out the countercurrent contact between the heavy water and the heavy hydrogen; burning the tritium-depleted heavy hydrogen withdrawn from the top of the exchange reaction column to produce a tritium-depleted heavy water; recycling the tritium-depleted heavy water to the heavy water source; p1 leading the remaining part of the tritium-enriched heavy hydrogen generated from the heavy hydrogen gas generator into a hot-wire type thermal diffusion colunm to enrich tritium; and withdrawing the tritium gas from the thermal diffusion column.
