Magnetohydrodynamic and thermal analysis of PbLi flows in poloidal channels with flow channel insert for the EU-DCLL blanket

Abstract: Magnetohydrodynamic (MHD) processes are known to be critically important for the dual coolant lithium lead (DCLL) breeding blanket (BB) concept. In order to minimize the MHD pressure drop in the European DCLL blanket design, the liquid metal breeder (PbLi) is decoupled electrically from the ferritic–martensitic structure (EUROFER) using insulating ceramic-based flow channel inserts (FCIs). The impact of the FCI on the velocity profile and the pressure drop in the DCLL front poloidal channels is studied. Two-di… Show more

“…A full segment "banana" DCLL blanket (poloidal length ~10 m) stretches all the way from the bottom to the top of the vacuum chamber as that in the US FNSF design [21]. Contrary to this, the EU DCLL DEMO design [22] has a modular structure where several modules of about 2 m each are fed from the shared manifold situated at the back of the blanket. To our best knowledge, there has been no comparison analysis of the MHD pressure drop between the "banana" and modular blanket for the same fusion reactor and operation parameters.…”

“…In these equations for a Q2D MHD flow, U and V represent the average of the local velocity between the two Hartmann walls. The last terms on the right-hand-side of Equations (21) and (22), which are linear in U and V, are the so-called Hartmann damping terms. They appear as a result of the integration and express the effect of viscos friction in the Hartmann layers on the core flow.…”

“…Before the commercial application of fusion energy can be realized, a series of key technical problems of liquid LiPb cladding must be solved, and the liquid LiPb experimental loop is the necessary experimental platform for studying these key technical problems [5,6]. The FDS team of Chinese Academy of Sciences has continuously carried out the design, construction and experimental research of DRAGON series lithium lead experimental loop for many years, which has carried out a good foundation for the research of liquid lithium lead cladding in China [7][8][9].…”
