Subject: Damage evaluation of steels used in nuclear power plants with electromagnetic nondestructive methods

Summary: Chromium-rich steel, one of creep resistant steels, is one of candidate materials for next generation nuclear power station with high efficiency, especially for steam turbine components. They are exposed to severe conditions of 450-600 C and 15-100 MPa. Under such condition, creep damage is dominant as life-limiting mechanism. Therefore, some nondestructive methods are required for detection and evaluation of creep damage in chromium-rich steels. Carbide precipitation and void generation precede creep damage and these phenomena affect magnetic properties of chromium-rich steel. The aim of this work was to investigate the use of magnetic property measurements as a nondestructive tool for micro-structural evaluation in chromium-rich steels.

Subject: Generation of high energy Xray by ultra intense laser

Summary: The ultra intense laser can accelerate electrons in the plasma to the MeV region. Such an electron can generate high energy Xray by bremsstrahlung in a metal converter. The high energy Xray can be utilized for trace element analysis, positron generation, photonuclear reaction and so on. The successful candidate will analyze the dynamics of the generation mechanism by monte calro code GEANT4, treat experimental results to optimize the conditions, and discuss the applications quantitatively.
