MHD equilibrium and stability of NUWMAK
NUWMAK is a high power density, noncircular conceptual tokamak fusion reactor design. The device is found to be magnetohydrodynamically stable except for vertical instability due to bad curvature of the external B/sub z/ field. The MHD equilibrium properties of NUWMAK are obtained by solving the Grad-Shafranov equation numerically. Only 8 equilibrium field coils are required to provide plasma equilibrium and proper shape control. The average plasma power density is about 10.1 MW/m/sup 3/ and the neutron wall loading is 4.3 MW/m/sup 2/. The plasma current is 7.2 MA, the major radius is 5.13 m, the plasma width is 1.13 m and the plasma height to width ratio is 1.64. The on-axis magnetic field is 6.05 Tesla and toroidal ..beta.. is 6% while the safety factor q at edge is found to be 2.63.
