It's hosted on Mitsubishi Heavy Industry's research page, which gives me a warm fuzzy.
I don't see any cold fusion going on there. It would be nice to see the stoichiometries of all of the input/outputs, but I suspect that Iwamura was describing an alternate method of isotope production. Making isotopes is nothing new. The figure showing deuterium gas on either side of the Pd barrier puzzles me; if the deuterium is part of the reaction, I expect to see some reaction products mixed with it after it goes through the barrier. I'd also like to see the atomic weights of the Cs (starting material) and the Pr (end product).
In any case, transmutation =/= cold fusion.
