ARIES tokamak reactor study
This report examines the feasibility of a standard poloidal diverter design for ARIES- 2/4 with the determination of the peak thermal loading on, and the plasma temperature facing a poloidal double null diverter. The ARIES-2/4 reactors produce 2,141 MW of fusion power of which 1712 MW is contained in the neutron channel. Of the remaining 429 MW of charged particle power, 47 MW is radiated from the core by bremsstrahlung and synchrotron modes to the vessel walls. The remaining 382 MW of charged particle or transport power crosses the core/edge interface. The fact that the bulk of the power is contained in the neutron channel makes the application of a poloidal divertor possible. The ARIES-2/4 diverter constraints for peak heat load and peak particle temperature are set by current technology and materials knowledge. Divertor geometry constraints are imposed by the plasma equilibrium and the 2/4 vacuum vessel. The diverter heat load and plasma temperatures are determined from edge particle and energy balances. These balances are important characteristics of the plasma edge because the transport power from the plasma core must pass through the edge and be deposited on tokamak components. The Braams' B2 code is a multifluid ion and electron energy and momentum transport code for the plasma edge and is adopted for the design of the ARIES-2/4 diverter.
