In particular, all the material which is said to be

prize winning physicist, Carlo Rubbia and has been analysed in great detail
by a group of high energy particle physicists, The process has been shown to
be entirely feasible.

I would be intensely interested in any material on the web that you
could direct my attention to, concerning this.

If it is true, it needs serious evaluation.

What you aretalking about is essentially ';sterilisation' of long lived
isotopes by blasting them in and around a recator into presumably
somewhat 'hotter' but less enduring isotopes, that could be stuck
somewhere for ten years, and then be 'cold' enough to dispose of in more
normal ways?
