I agree that the amount of heat generated would be the determining factor in the usefulness of this phenomenon as a widespread energy source.
But even as a minor energy source, if it is cost-competitive with oil/coal/solar/etc. etc., will help.

If it works, which is in doubt, the real problem would be scaling up. It would be bigger by far than an ordinary nuke plant if it is to do the job of a nuke plant. Bigger than a coal plant. Much bigger. Not cheap either.
