ENEA experience in LBE technology

Since 1999, several facilities have been operated with flowing LBE in the frame of ADS R&D activities at CR ENEA Brasimone. The experimental activities have gone through thermal-hydraulics, heat exchange, science of materials, qualification of components and operational procedures. Thanks to the performed work, a large amount of observations were made, and experience was gained. This paper is focused on the survey of these experiences gained, in order to point out advantages and disadvantages of the LBE technologies. In particular, experience on plant components, measurement instrumentations and operational procedures will be pointed out.
