Wrong, hahaha. Your linked article says something different. Tritium inventory will be to low to sustain research long before 2050, by 2035 inventory shriveled to not be able to support anything but ITER!
The CANDU reactors are end of life and going offline.
No, most commerical reactors can't be tritium sources, would poison the environment to have your commercial PWR or BWR doing it by putting in lithium rods, they're not allowed to!
Instead of pissing away tens of billions on a pipe dream that may not work out, we should be going to the energy supplies that have millennia of fuel. Nuclear fission with uranium and thorium. Already our "spent fuel" really is a goldmine of energy with 7 times more the energy that can be extracted in a proper reactor than we've already used. And those proper reactors would leave short lived waste to boot, not these thousands of years of curse waste we have now.
