In a flow system with Mercury as a liquid metal, an erosion is expected to occur and piping wall thickness wm be decreased. In order to estimate a lifetime and a stability of mercury flow system, erosion experiments are conducted by using mercury experimental loop in JAERI. A test section used in these experiments is circular tube of about 1330mm length including elbow, welding points and test plates. The erosion is estimated by measuring the tube wan thickness. Wall thickness is measured by using ultra sonic thickness gauge. At present, the duration of experiment is less than 1000 hours. Preliminary experiment was carried out during 668 hours. The measured data was compared with initial data. As a result, it was made clear that the decreasing of wall thickness by erosion was very small and not effective on lifetime and stability of mercury target circulation system.
