Abstract

The International Fusion Materials Irradiation Facility (IFMIF), presently in the Engineering Validation and Engineering Design Activities (EVEDA) phase was started from 2007 under the frame of the Broader Approach (BA) agreement. In the activities, a prototype Li loop with the world's highest flow rate of 3000�L/min was constructed in 2010, and it succeeded in generating a 100�mm wide and 25�mm thick with a free-surface lithium flow along a concave back plate steadily at a high-speed of 15�m/s at 250��C for 1300�h. In the demonstration operation it was needed to develop the Li flowing measurement system with precious resolution less than 0.1�mm, and a new wave height measuring method which is laser-probe method was developed for measurements of the 3D geometry of the liquid Li target surface. Using the device, the stability of the variation in the Li flowing thickness which is required in the IFMIF specification was ��1�mm or less as the liquid Li target, and the result was satisfied with it and the feasibility of the long-term stable liquid Li flow was also verified. The results of the other engineering validation tests such as lithium purification tests of lithium target facility have also been evaluated and summarized.
