    In recent years, the scale and development of systems has become larger and more complex, and various components of the system had more complicated relationships. Regardless of the situation, the traditional safety analysis method has been kept, and the systems have been continuously causing serious accidents and losses. Because of this, a relatively new safety analysis method STAMP/STPA, which focuses on the mutual interaction among the components of the system has been garnering more attention. Specifically, even until now in Japan, this method has not been applied to systems in various industries. Recent serious accidents and losses have been caused by the defects made in the requirement development phase, and the number of such defects has been increasing. The focus of this research is the application of STAMP/STPA to the requirement development phase, and it is aimed to develop the system that is highly safe in an early development phase. For these purposes, we propose（1）additional items for a requirement definition document,（2）rules for describing requirements, and（3）an application process for using STAMP/STPA in actual development projects. Furthermore, we propose to show the solutions to solve problems about using STAMP/STPA in actual development projects by applying our proposals to the radiation treatment system.
