Abstract
Lead bismuth is to be used as spallation neutron sources and coolant in the sub-critical reactor at the accelerator driven transmutation system (ADS), for reducing the amount of the minor actinide (MA) and the long-lived fission products (LLFP) in the high level radioactive waste. As lead bismuth is used at elevated temperatures, technical issue is to compromise with material performance under flowing lead bismuth and/or with radiation damage by high-energy protons and neutrons. This paper presents a recent activity of target design and lead bismuth technology, which covers flowing tests of lead bismuth, stagnant corrosion tests, oxygen sensor and cleaning techniques. Materials used are SS316.
