THE BENEFITS OF TOKAMAK REACTOR MAGNET DESIGN ON STEADY STATE OPERATION
There are at least four areas where reactor magnet design might benefit from steady state (ie about 1 pulse per day) operation: reduced crack growth in coil materials; reduced refrigeration requirements against eddy current heating; reduced poloidal field (PF) power supply requirements, and some possible benefits of a reduced specification for the primary (ie ohmic heating) coil. Against these benefits must be weighed any detrimental effects of exotic means of sustaining the burn, any inbuilt redundancy to permit operation while current drive is out of action, and any higher fields needed to provide increased power output to compensate for larger circulating power requirements. This note expands on these advantages and disadvantages and indicates those areas where further quantitative work is necessary.
