New modular concept for the helium cooled pebble bed test blanket module for ITER

Neutronics design and supporting experimental activities in the EU

“…The neutronic TBM will be a "lookalike" configuration showing the same nuclear features as the DEMO blanket module. Detailed 3D Monte Carlo calculations have been performed for design and optimising the HCPB plant integration and neutronics TBM variants [11]. The current effort is on the analyses of the shielding performance of the TBM taking into account the detailed configuration of the TBM, the back plate with the manifolds, the attachment, the pipe connections and penetrations.…”

The European breeding blankets development and the test strategy in ITER

“…It is expected that HCLL and HCPB TBMs [11,12] will be tested separately in two ITER equatorial half ports. TBMs shall include all relevant technologies foreseen for the corresponding DEMO blanket, provided they have an impact (and the possibility to measure it) on the results of the tests.…”

Experimental and numerical investigations of heat transfer in the first wall of Helium-Cooled-Pebble-Bed Test Blanket Module—Part 2: Presentation of results

“…The details concerning the motivation for these investigations, the design, fabrication and assembling of HETRA test section as well as the development of corresponding 3D CFD model have been presented in the previous report on this study (see [1]). Further, since 2009 the original HCPB TBM Version 1.1 (on which HETRA design was based) has been updated, 3D CFD modelling verified in the framework of HETRA activities has been applied to compute the heat removal from the first wall of the currently accepted HCPB TBM Version 2.1 (main characteristics of HCPB TBM Version 1.1 and 2.1 are summarized in Table 1 in [1], for more details see [2,3]). This paper is organized as follows.…”
