    When excessive pressure is generated in the auxiliary feed water tank for the nuclear power plant, a safety valve shall be installed to discharge the pressure. This study is about the design, manufacture, and verification of the micro pressure safety related safety valves. A valve for the study was designed to have a natural frequency of more than 33 Hz and to satisfy the seismic coefficient for the installation location. In order to satisfy micro set pressure, a study has been conducted by optimizing the material and manufacturing of the valve seat. In addition, the operability and the capacity of the valve was verified by certification of ASME QME-1 and ASME NBBI, which are essential requirements for the safety related safety valves. It is expected that domestic nuclear power industry technology will develop through localization of micro set pressure safety related safety valves.
