Basic Study on Cold Transmutation of Isotopes and Theoretical Interpretation Abstract Incineration of Long-Lived Nuclear Wastes (LLNW) from nuclear power plants is of interest. The MHI-Iwamura type experimental method for "Cold Transmutation of Isotopes" may have great potential. It should be confirmed and applied for LLNW transmutation. The Italian-Japanese project is of basic study for this aim. A theoretical background as TSC(Tetrahedral Symmetric Condensate)-induced nuclear reactions in D/H loaded metal systems is explained. 4D/TSC may dominantly induce self-fusion of 4D to produce He-4 ash as radiation-less clean fusion reaction. In addition, 4D/TSC and 4H/TSC may form sub-pm size charge-neutral pseudo-particles which may induce direct nuclear reactions with neighboring heavier isotopes to make transmutations. Some detail of theoretical modeling and numerical results on reaction rates for transmutations of Cs-to-Pr, Sr-to-Mo, and so on are shown, as working scenarios of the IJ-project.
