Description
Summary:•Russian beryllium of TGP-56FW grade has been accepted for the ITER first wall application.•Experimental technology of TGP-56FW grade, has been successfully introduced to the industry.•Further R&D will be directed on the cost reduction and increasing the efficiency of production.•Performances of TGP-56FW grade and S-65C grade under ITER-like loads are very similar. Progress of R&D activities on the development and improvement of manufacturing technology of the billets and tiles made of TGP-56FW beryllium is traced and also some actions aimed on the preparation of mass production is reported. Additionally, the results of comparative study are presented on influence of transient plasma heat loads with the energy density of 0.3–1.0MJ/m2 at 250–500°C (performed in QSPA-Be plasma gun facility), on the erosion and surface damage of beryllium tiles made of TGP-56FW grade (RF) and S-65C grade (USA).
