It is necessary to clarify the influence of the nuclear transmutation helium on the grain boundary embrittlement of the materials from the viewpoint of utilization of the high-burnup nuclear fuels and the viewpoint of the plant life management of the power station of safer operation. A laser shock spallation method was developed, by research activity concerning especially reproducibility, the detection limit and accuracy of reduction of grain boundary strength were clarified, and the feasibility to direct measurement of helium grain boundary embrittlement was shown.

有必要从利用高燃烧核燃料的观点以及更安全操作的动力站的植物寿命管理的观点来阐明核透射氦对材料晶界的影响。开发了一种激光休克散布方法，通过有关特别可重复性的研究活动，阐明了晶粒边界强度的降低的检测极限和准确性，并显示了直接测量氦晶晶界边界的可行性。
