Abstract :
The impact of improvements in plasma confinement and beta on commercial tokamak embodiments has been systematically investigated. Cases were investigated for both steady-state and pulsed reactors. A narrow range of useful confinement enhancement (H factors over the ITER-89 Power scaling) and Troyon beta limit coefficients g are found to be beneficial for reducing the cost of electricity (COE). Improvements in the beta limit (i.e., g) offer the greatest improvement in reactors. For g limited to about 4, H factors of only 2 are needed. If g of 6 is attainable, H factors up to 2.5 are useful. Pulsed reactors have slightly higher useful H factors, ranging from 2.5 for g near 4 to 3 for g near 6
