Tritium production

Hi all

Anyone has an idea how to produce tritium from heavy water at home?

Heavy water is deuterated, not tritiated (is that a word?)
so you cannot produce it from heavy water,
though.. Neutron bombardment of lithium 6 gives tritium!

There is a really useful effect called "photodisintegration". For the deuterium, it means that if an enough energetic gamma ray (2.75-MeV) hits the deuterium core, than it could "liberate" a neutron from it.
The neutron what comes out is energetic, so you have to slow it down (D2O is also good for this) and there will be a chance that a deuterium atom will absorb it forming tritium.

Sadly the oxygen has almost as large neutron cross section as the deuterium, but if you do it for a long time and could reflect back the neutrons in a good yield, than it could produce some tritium.

Another bad thing is that the tritium could also lose 1-2 neutron from the energetic gamma rays.

I have a blog where I post my pictures from my work:
