How do you get tritium?

Answer 1

There are several ways to store tritium.

It can be stored as a gas for short term storage (as in nuclear weapons -- the gas in the tritium reservoir needs to be replenished periodically; or tritium illumination for watches or survival gear -- these wear out and go dim over time.).

For longer term and final storage, a hydride storage vessel using a uranium metal bed, or better yet, a titanium sponge can be used. Most of the gas can be recovered from these systems by desorption under vacuum. To remove the rest, isotopic exchange is required.

Answer 2

Tritium is typically produced by bombarding lithium-6 with neutrons in a nuclear reactor. It can also be extracted from heavy water (deuterium oxide) in a process known as isotopic exchange. However, due to its radioactivity, tritium is strictly regulated and requires special licenses for handling and use.

Answer 3

I can get a tritium from hydrogen by reacting a neutron with a hydrogen by some techniques (security).
