“…This permits a reliable extrapolation of experimental data to ITER applications. Considering the space available in the uniform magnetic field and that needed around the test section for instrumentation, a mock-up scaled down by a factor two with respect to the proposed blanket design [1] has been fabricated. The test section consists of 4 breeder units fed and drained by circular pipes and manifolds.…”

“…The European concept uses an eutectic lead lithium alloy, PbLi, to breed the fuel component tritium, and helium flowing at high pressure in channels embedded in the walls to remove the thermal power. A helium cooled lead lithium (HCLL) blanket module consists of rectangular boxes, named breeder units (BU), assembled to form columns [1]. Cooling plates are inserted in each box for heat extraction.…”

“…It is important to predict and control the deuterium and tritium Inventory in, Permeation through and Recycling from (IPR) the reactor walls, where, in general, inventory and permeation should be minimized. Moreover, understanding, controlling and therefore predicting H transport phenomena is a key requisite in the design of core fusion reactor components like He Cooled Lithium Lead (HCLL) Breeding Blankets (BB) (see, e.g., Salavy et al [1] for details on HCLL design), extraction systems of future nuclear fusion reactors, high energy conversion fission reactor systems involving Lead Bismuth Eutectic (LBE) alloy and steam, and liquid metal experimental facilities.…”

The present work intend to be a first step towards the understanding and quantification of the hydrogen isotope complex phenomena in liquid metals for nuclear technology. Liquid metals under nuclear irradiation in ,e.g., breeding blankets of a nuclear fusion reactor would generate tritium which is to be extracted and recirculated as fuel. At the same time that tritium is bred, helium is also generated and may precipitate in the form of nano bubbles. Other liquid metal systems of a nuclear reactor involve hydrogen isotope absorption processes, e.g., tritium extraction system. Hence, hydrogen isotope absorption into gas bubbles modelling and control may have a capital importance regarding design, operation and safety.Here general models for hydrogen isotopes transport in liquid metal and absorption into gas phase, that do not depend on the mass transfer limiting regime, are exposed and implemented in OpenFOAM R CFD tool for 0D to 3D simulations. Results for a 0D case show the impact of a He dispersed phase of nano bubbles on hydrogen isotopes inventory at different temperatures as well as the inventory evolution during a He nucleation event. In addition, 1D and 2D axisymmetric cases are exposed showing the effect of a He dispersed gas phase on hydrogen isotope permeation through a lithium lead eutectic alloy and the effect of vortical structures on hydrogen isotope transport at a backward facing step.Exposed results give a valuable insight on current nuclear technology regarding the importance of controlling hydrogen isotope transport and its interactions with nucleation event through gas absorption processes.
