Description
An experimental apparatus to investigate cavitation damage in sodium using vibratory method was designed, fabricated and tested. This report describes the explanation of the apparatus and shows some preliminary test results. Important findings from the test results are (1) erosion rate (weight loss rate) shows significant dependences on sodium temperature and pressure. (2) erosion rate drastically decreases beyond 300 C of sodium temperature at pressure of 1 kg/cm2G, and very little cavitation damage was observed above 350 C. (3) a maximum erosion rate was observed at about 1 kg/cm2G in the pressure range of 0.2 - 7.0 kg/cm2G at sodium temperature of 300 C. (4) erosion rates in sodium are much larger (10 times or more) than those in water or liquid nitrogen in some cases. (author)
