The fundamental role of fluid dynamic analyses in the design of the solid EU Test Blanket Module

Design integrated system for power plant development

“…A similar arrangement suitable for a 12 x 12 cell arrangement is shown in figure 11. On basis of the breeder blanket design an example is given by describing the already in KIT existing platform for the development, analysis and design verification: [4], [5], [6], [7] and [8]. The viewgraph presented in Figure 12 illustrates the organization of the Engineering Platform dedicated to the Breeder Blanket.…”

Non-linear failure analysis of HCPB Test Blanket Module

“…As for the previous studies [4] thermal boundary condition derived from neutronic analyses and CFD 3D model of the Breeding Zone [7] have been implemented. In particular the radial power density distribution of the heat generation calculated by the neutronic analyses is implemented as volumetric heat generation in the box structural components; and the heat generated in the Breeding Zone calculated by a 3D CFD model is implemented as detailed heat flux profile deposed on the components (see Fig.…”

“…In case of the FW the detailed investigation by 3D CFD models of the local Heat Transfer Coefficient (HTC) is a key step for the correct computation of the thermal gradient, and thus the stress level, through the FW thickness [7]: 3D distributions of local HTC have been implemented directly as input from the 3D CFD model. Temperature dependent HTC computed by Gnielinski correlation are For taking this into account in the FE model which only considers a quarter of the box the fluid lines simulating in the FE calculations the convective heat transfer are cut in the FW.…”

Thermo-mechanical analyses and assessment with respect to the design codes and standards of the HCPB-TBM Breeder Unit

“…Heat generation due to nuclear heating is set in the pebble beds and structural steel according to the results of [6]. Inlet temperatures of the helium coolant in the different subcomponents are calculated by an analog CFD model performed in Ansys CFX [13]. Convection boundary conditions are applied in the TBM manifolds with constant helium bulk temperatures and an approximated mean heat transfer coefficient of 2000 W/m 2 K. The Gnielinsky correlation is implemented in the cooling channels of the cooling plates to calculate the heat transfer coefficient as a function of temperature [14].…”
