Annular mist flow Flow pattern Liquid Drop Impingement Erosion Mist flow Nuclear Power Plant Operation Outage loss Plant Trip TRAC code Two-phase flow
The high level maintenance technology has become necessary to increase a capacity factor of nuclear power plants. In a nuclear power plant, There are various kinds of troubles concer ning with pipes. One of them is a small leak from a small hole by liquid drop impingement erosion (LDIE). Even such a small leak, it was sometimes a cause of the plant trip and an eco nomical losses about 200M$ during several month outage, by operating a 1000MWe fossil power plant. We conducted a LDIE test by using a test spec...

High Speed Two Phase Flow Liquid Droplet Impingement Erosion Wastage of Pipe
Evaluation of wastage speed for nuclear power plant maintains plant reliability and power up rating is important. There are two main cause of wastage flow accelerated corrosion (FAC) and mechanical erosion. This study is to develop evaluating the wastage speed by liquid droplet impingement erosion (LDIE). LDIE oft en occurs at downstream of corner of pipe or orifice. In this study, the liquid drop impinging tests were conducted with the test pieces mounted on a high speed rotating disk that cross thin wate...
