Nuclear power plants are required to have especially high reliability and increasingly longer service life. As a contribution to the solution of these issues, an analysis was conducted on steam field-related troubles and their causes based on a data from an online database that tracks troubles at nuclear power plants and the authors experience. As a result, the reality of piping damage attributed to the two-phase flow of steam and condensate characteristic of nuclear power plants was elucidated. This note introduces preventive measures against piping damage to steam and condensate lines that has been proven effective through actual use in various industries under the following topics: 1) technology for the separation of steam/condensate in steam piping, 2) technology for the discharge of condensate from steam piping, and 3) technology for the measurement, inspection or monitoring of steam and condensate lines.
