In the dual-coolant lead lithium (DCLL) blanket, the
key element is the flow channel insert (FCI) made of a
silicon carbide composite (SiCf /SiC), which serves as
electric and thermal insulator. The most important mag-
netohydrodynamic (MHD) and thermal issues of the FCI,
associated with MHD flows and heat transfer in the po-
loidal channel of the blanket, were studied with numer-
ical simulations using the U.S. DEMO DCLL design as a
prototype. The mathematical model includes the two-
dimensional momentum and induction equations for a
fully developed flow and the three-dimensional (3-D) en-
ergy equation. Two FCI modifications, one with no pres-
sure equalization openings and one with a pressure
