AB  - This paper deals with cooling of the first wall of Helium-Cooled-Pebble-Bed Test Blanket Module (HCPB TBM) for ITER. The first wall cooling is an important investigation issue due to an extreme asymmetry of heat loads: heat flux on the plasma facing side is several times stronger than the one on the side which faces breeding units. Our preliminary 3D CFD analysis revealed that under such conditions the heat transfer coefficient is significantly lower than predicted by common heat transfer correlations (see Ilic et al., 2006). For an experimental validation of these results HETRA (HEat TRAnsfer)test section has been designed and built at the Institute for Neutron Physics and Reactor Technology in Karlsruhe Institute of Technology. The HETRA test section involves in full scale one U-pass of the cooling channel in the first wall of HCPB TBM Version 1.1 (see Meyder et al., 2005). The HCPB TBM relevant experimental conditions have been provided: test channel made of Eurofer steel, helium coolant at pressure of 8 MPa and inlet temperature of 300 C and heat flux of 270 kW/m(2) at the channel surface representing plasma facing side of the first wall. Test channels with hydraulically smooth and with hydraulically rough walls have been built. At each test channel the temperature of Eurofer walls has been measured at 60 positions, For numerical investigations the 3D CFD modelling with the code STAR CD has been applied. This paper is the first report on this study and presents the development of the test section and of the 3D CFD model. The analyses of the obtained experimental and computational results are presented in the second report (see Ilic et al., 2014).

AB  - This paper is the continuation of the first report on investigations of heat transfer in the first wall of Helium-Cooled-Pebble-Bed Test Blanket Module for ITER submitted to this Journal (see Ilic et al. [ID. The investigations have been performed experimentally by manufacturing and testing of a mock-up and numerically through the development of corresponding 3D CFD models. The experimental tests have been conducted for HCPB TBM relevant conditions - the test channel made of Eurofer steel, helium coolant at pressure of 8 MPa and inlet temperature of 300 degrees C and heat flux of 270 kW/m(2) at the channel side representing plasma facing side of the first wall. In total six measuring series have been performed in which surface roughness, helium inlet temperature and heater power have been considered as parameters. For each measuring series corresponding 3D CFD computational scenarios have been conducted. By use of experimental data for Eurofer temperature it was possible to verify 3D CFD models. On the other side, 1D CFD approaches failed in comparison with experimental data. Further, a critical analysis of the use of microscopic surface roughness as a method for heat transfer improvement in the first wall has been presented. Finally, based on a detailed analysis of experimental and 3D CFD data obtained in the framework of these activities the main directions for an improvement of cooling channels in the first wall could be proposed.

AB  - This paper presents an experimental test section which has been developed at the Institute for Neutron Physics and Reactor Technique in Karlsruhe Institute of Technology for investigations of heat removal from the first wall (FW) of the Helium-Cooled-Pebble-Bed Test Blanket Module (HCPB TBM). The test section named HETRA is attached to HEBLO facility which can provide Helium parameters relevant for HCPB TBM conditions-pressure of 8 MPa and inlet temperature of 300 degrees C. The purpose of planned investigations is to verify numerically found decrease of heat transfer coefficient due to a pronounced asymmetry of heat loads at the first wall of HCPB TBM. This paper describes how HETRA test section has been built: from its design over fabrication to the assembling. The planned measurements are also explained by presentation of a detailed measuring scheme. Finally, the first results concerning experimental and computational determination of pressure losses in HETRA cooling channel are presented.

AB  - 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.
