Eh, not really. You can futz with the probability distribution, like a fast neutron will cause a different distribution of fission products than a slow one... but it is still a very random process. You can't control it like an expert at a billiards table. Especially the strong force mediated interactions between particles in the nucleus. Some people just won't believe you though.
By correctly molding the energy landscape it may be possible to set the states and state transitions up in a beneficial way for what he proposed.
