Abstract :
The effects of the inclusion of the SiC flow channel insert (FCI) in a dual-coolant lithium-lead (DCLL) blanket placed in a representative Demo reactor on various key neutronics parameters are studied. These parameters are: tritium production ratio (TBR), power multiplication (PM), profiles of nuclear heating, peak damage parameters (dpa, helium and hydrogen production rates) in the structure, vacuum vessel and shield, peak heating rate and fast neutron fluence in the TF coils. Various thicknesses and density factors of the FCI are considered. These effects are examined in both radial and toroidal direction by 1-D and 2-D models.
