Integration of the Modular Dual Coolant Pb-17li Blanket Concept in the Aries-cs Power Plant
A modular DCLL blanket is selected as the reference concept in the ARIES-CS power plant study. This concept is characterized by the following features: 1. Eutectic lead lithium alloy Pb-17Li serving as breeder and coolant (“self-cooled breeding zone”); 2. Helium-cooled FW and blanket structure made of the MF82H Reduced Activation Ferritic Steel (RAFS); 3. Flow channel inserts (FCI) made of SiCc...
متن کاملNumerical analysis of MHD flow and heat transfer in a poloidal channel of the DCLL blanket with a SiCf/SiC flow channel insert
MHD flow and heat transfer have been analyzed for a front poloidal channel in the outboard module of a Dual Coolant Lithium Lead (DCLL) blanket, with a flow channel insert made of a silicon carbide composite. The US reference DCLL blanket module [C. Wong, S. Malang, M. Sawan, S. Smolentsev, S. Majumdar, B. Merrill, D.K. Sze, N. Morley, S. Sharafat, P. Fogarty, M. Dagher, P. Peterson, H. Zhao, S...
متن کاملAn overview of dual coolant Pb–17Li breeder first wall and blanket concept development for the US ITER-TBM design
An attractive blanket concept for the fusion reactor is the dual coolant Pb–17Li liquid (DCLL) breeder design. Reduced activation ferritic steel (RAFS) is used as the structural material. Helium is used to cool the first wall and blanket structure, and the self-cooled breeder Pb–17Li is circulated for power conversion and for tritium breeding. A SiCf/SiC composite insert is used as the magnetoh...
متن کاملQUANTIFICATION OF DOMINATING FACTORS IN TRITIUM PERMEATION IN PbLi BLANKETS
In this paper the problem of tritium transport in PbLi (Lead-Lithium) blankets has been studied and analyzed by means of our recently developed computational models. Several simulations are performed by incorporating the geometric configurations of the PbLi blankets including both DCLL (Dual Coolant Lead Lithium) and HCLL (Helium Cooled Lead Lithium) blankets. Tritium permeation loss percentage...
متن کاملTritium Transport in Poloidal Flows of a Dcll Blanket
In a Dual-Coolant Lead-Lithium (DCLL) blanket, tritium losses from the PbLi into cooling helium streams may occur when the liquid-metal breeder is moving in the poloidal ducts. Quantitative analysis of the mass transfer processes associated with the tritium transport in the breeder as well as tritium diffusion through the structural and functional materials is important for two main reasons. Th...
