This will probably end up pushing us to Lithium fusion pretty fast, the fuel is a lot more common and the temperature requirement is only a little hotter. That said nuclear proliferation from tritium is a lot less of a risk than from uranium. Anyone can put together a nuclear event with sufficient enriched uranium, pinching tritium to fuse using a fission event, well it's a significant technical hurdle.
