Mock-up testing facilities and qualification strategy for EU ITER TBMs
European test blanket modules (TBM) for both European blanket concepts, namely the Helium Cooled Lithium Lead (HCLL) and the Helium Cooled Pebble Bed (HCPB), and their auxiliary systems have been designed in the last years. This paper presents the experimental facilities available in Europe for the qualification tests of European TBMs. In particular, devices designed to analyze specific technological issues, for example corrosion under strong magnetic fields or tritium management and extraction, as well as large scale facility to perform integral tests are described. A preliminary overview on the qualification strategy is presented and discussed.
Riga experience in spallation neutron target related investigations
Abstract Mercury has awakened interest as a potential material for spallation neutron source targets. Institute of Physics, University of Latvia has a 30 years experience of investigations in mercury. As specially projected building includes a 350 m2 experimental hall. The largest loop, containing 5×103 kg of Hg, can be transferred for solution of different tasks. As the first example results are presented when integral developed pressure and local (distribution of void fraction) characteristics of a two-phase mercury/gas riser were investigated. Second example – investigation of velocity fields and heat transfer conditions close to the beam entrance window in the SINQ target thermohydrauli…
First Results of the Testing of the Liquid Gallium Jet Limiter Concept for ISTTOK
The use of liquid metals as plasma facing components in tokamaks has recently experienced a renewed interest stimulated by their advantages to the development of a fusion reactor. Liquid metals have been proposed to solve problems related to the erosion and neutronic activation of solid walls submitted to high power loads allowing an efficient heat exhaustion from fusion devices. Presently the most promising materials are Lithium and Gallium. ISTTOK, a small size tokamak, will be used to test the behavior of a liquid Gallium jet in the vacuum chamber and its influence on the plasma. This paper presents a description of the conceived setup as well as experimental results. The liquid Gallium …
