概要
Nuclear power plants are required to have especially high reliability and increasingly longer service life. As a contribution to the solution of these issues, troubles unique to nuclear po wer plants caused by two-phase flow of steam/condensate were identified through analysis from a new perspective on problem areas and causes focusing on the steam field using a database tha t tracks troubles at nuclear power plants. Additionally, useful technology for prevention against the effects of these troubles that occur in steam/condensate piping, such as erosion-induc ed pipe wall thinning and potential water hammer, are reported under the categories of 1) steam lines, 2) condensate lines, 3) measurement, inspection or monitoring of equipment or piping.
