A rapid removal method for protium in tritiated hydrogen isotope gas

Abstract

The present invention provides a method for quickly removing protium in tritiated hydrogen isotope gas, which comprises the following steps in turn: a. Leak rate inspection of the palladium retention method for reducing the protium, charging to 1.5 MPa, and keeping the pressure for 60 minutes; b. Purifying pretreatment before; c, purification treatment; d, post-treatment. By adopting the rapid removal method for protium in tritium-containing hydrogen isotope gas of the present invention, it is possible to obtain tritium-containing hydrogen isotope gas with low content of protium.

Description

technical field

[0001] The invention belongs to the technical field of hydrogen isotope processing, and in particular relates to a method for quickly removing protium in a tritium-containing hydrogen isotope gas. Deuterium-tritium gas with a protium content of less than 1%. Background technique

[0002] Energy, economy and environment are the three major issues facing the sustainable development of human society today, among which energy is the basis for sustainable development of economy and environment. Nuclear fission energy is a new energy source that appeared in the 1960s. After nearly half a century of development, it has now reached a considerable scale. By the end of the 20th century, the world's installed capacity had reached 430GW, and fission energy contributed 7% to the total energy. Just as the electrical output of a conventional power plant is impossible without coal or natural gas, the electrical output of a fusion reactor is impossible without a full deuter...
