Nuclear renaissance isn’t possible without the development of new nano-hetero-structured materials. A novel micro-hetero structure, entitled "cer-liq-mesh", nuclear fuel that self-separates the fission products from nuclear fuel, makes fuel reprocessing easier, allowing near-perfect burnup by easy fast recladding, being prone to improve the nuclear fuel cycle. Fuel heating analysis led to development of new direct energy conversion nano-hetero structured meta-materials resembling a super-capacitor loading from nuclear particles’ energy and discharging as electricity, prone to remove 90% of the actual nuclear power plant hardware, increasing the energy conversion efficiency. Usage of ion beam recoil analysis is used to measure and prove the nano-grains’ and nano-clusters’ special properties, such as shape-enhanced impurity diffusion and self-repairing in cluster structured fractal materials. The nano-grain liquid interface is studied by ion beam simulation in order to develop a new generation of nuclear fuels with enhanced breeding and transmutation properties, able to directly separate the transmutation products, thus reducing the need for hard, hazardous chemical processes. Ion-beam channeling in material may be extended to neutrons and gamma rays, and using hybrid NEMS structures new applications may create novel solid-state nuclear reactor control reactivity system, radiation modulators for gamma, neutrino communication systems and ultra-light radiation shielding.
