【 摘 要 】

Practical tokamak reactors will need to maintain high ion temperature and nD approximately equal to nT in the core for long durations. These conditions will necessitate low energy transport, low impurity concentrations, and high bootstrap current. Large extrapolations from present experiments are needed to predict performance. A number of approaches are being used for these extrapolations including: (1) dimensionless scaling arguments, (2) empirical scaling, and (3) physics-based simulations of anomalous transport.
