“Remember tritium is a form of hydrogen which diffuses wonderfully through most materials.”
How is Canada storing their tritium?
How does the tritium stay in H-bombs?
Don’t know about bombs, but normally tritim is stored in special stainless steels that have low diffucion rates for tritium. But these storage systems have no other functional requirements except to store tritium, don’t have to operate at very high temperatures in high neutron flux and x-ray environments, etc. And even so, there is diffusion into the walls of the container. It is just so slow that it doesn’t come through the other side.
