Abstract
Experiments were performed on FTU with a cooled liquid lithium limiter (CLL) and subsequently with a cooled liquid tin limiter (TLL) (end 2016) aimed at testing liquid metals (LM) under reactor relevant thermal loads of up to 10 MW/m2 nearly stationary conditions. In the European framework of coordinated actions, a cooled sample of Sn CPS type envisaged for the TLL in FTU has been tested on Pilot-PSI linear device. A power handling of 26 MW m-2 has been demonstrated under stationary conditions and without apparent damage of Sn sample, giving early indications the TLL will be effective. In this paper an overview of the main activities of the last two years will be presented followed by the experimental results obtained on FTU with the new CLL system. Then, the preliminary work with the tin liquid limiter (TLL) and the results on Pilot-PSI with liquid tin samples will be described.
