Quantum beam applications in nuclear energy industries

Minehara, Eisuke; Morishita, Yoshitsugu ; Mizuki, Junichiro

The advanced quantum beam technologies (synchrotron orbital radiation and laser) are applied to the nuclear energy industrial one and many other fields, and solving various actual difficulties and acquiring much new knowledge in Quantum Beam Science Directorate, Japanese Atomic Energy Agency. Here, we would like to introduce and to explain three ones from such activities stated just above. In the text, we would like to explain in details (1) the high power laser cutting with narrow-gap in decommissioning the nuclear power reactor plants, (2) complete removing of RI (radio-isotope) contaminated surface components using non-thermal laser ablation, and (3) the discovery of the high temperature superconductor working mechanism using synchrotron-orbital-radiation beam as three typical examples.
