Self-consistent plasma and engineering parameters for self-sustaining (ignited) tokamak power reactors

W.M. Stacey Jr1975年被引用 3Nuclear FusionIF 3出版社

Self-consistent calculations of the plasma energy and particle balances, the plasma current required for confinement according to trapped-ion instability theory, the toroidal magnetic field required for MHD-stability, the transformer magnetic field required to create and maintain the plasma current, and the maximum power allowed by either MHD-stability or neutron power flux to the first-wall limits are reported. If q ∼ 1 and can be achieved and if plasma contamination can be held to Zeff ∼ 1.3, then reactors with a wide range of geometries (R = 7.5 − 15.0 m, A = 3 − 5) with power outputs of 1−10 GW and burn times of the order of hours are feasible with realistic technological constraints – maximum toroidal fields at the coils less than 80 kG and maximum neutron power fluxes on the first wall less than 2.0 MW/m2. The consequences of operation under different plasma MHD-stability and technological constraints are also examined.
