| Research Abstract |
An experimental research was performed on the non-thermal processing of heavy and thick structure materials like a nuclear reactor vessel and nuclear fuel assembly, with using highly coherent and intense free electron laser (FEL) of pico-second pulses. Zircaloy4 alloy plates, which is material of fuel tube were tried and cut with FEL, and a state-of-art commercially available laser. The comparison of these showed that with FEL, very narrow-width efficient non-thermal processing is possible for those structure materials. Fundamental conditions for narrow processing or cutting were verified with using a nano-second pulse laser. As a result, technical specifications of laser lights and of optical systems for light guiding, were revealed and confirmed experimentally.
