NUWMAK: an attractive medium field, medium size, conceptual tokamak reactor
A new conceptual design of a medium field tokamak reactor shows that such systems can have high power density, a high degree of modularity, and moderate size. The design, called NUWMAK, is especially attractive from the viewpoints of system accessibility, low levels of long term radioactivity, and minimum penetrations. The power density (10 MW/m/sup 3/) and electrical power output (660 MW) are chosen as typical of a full scale reactor operating in a base-loaded mode. The plasma has a noncircular D shape and a toroidal ..beta.. of 6%. Plasma heating is by RF at omega = 2 omega/sub CD/ (92 MHz) based on the fast magnetosonic mode. The TF coil set is unique in that just 8 superconducting coils are used. A set of 16 small water cooled copper trim coils that do not encircle the vacuum chamber correct the field ripple to below 2%. The blanket is constructed of the titanium alloy, Ti-6A1-4V, and is designed to minimize thermal cycling, to provide internal energy storage, and to eliminate the need for an intermediate heat exchanger. A lithium-lead eutectic, Li/sub 62/ Pb/sub 38/, with a melting point of 464/sup 0/C is used as the tritium breeding and thermal energy storage material.
