IN.DAT info for DCLL:

 Select DCLL model
     i_blanket_type = 5 * DCLL

 Liquid Metal Breeder Material = PbLi
     i_blkt_liquid_breeder_type = 0 * Liquid Metal Breeder Material = PbLi

 Specify dual-coolant i.e., get mass flow required from heat extracted from liquid metal breeder
     i_blkt_dual_coolant = 2

 FIC switch: 0 = no FIC, Eurofer; 1 = FCIs, perfect electrical insulator, 2 = FCIs, with specified conductance
     i_blkt_liquid_breeder_channel_type = 0, 1, or 2

 Liquid metal duct wall conductance initialized at Eurofer value in fwbs_variables, or can input other value, used for i_blkt_liquid_breeder_channel_type = 0 or 2
     (bz_channel_conduct_liq)

 Choose if FW and BB structure are on the same pumping system (unless have different coolants), default is same coolant with flow IN->FW->BB->OUT
     (i_fw_blkt_shared_coolant)

 Can set inlet and outlet temperature for liquid metal breeder
     (inlet_temp_liq)
     (outlet_temp_liq)
