Abstract.  New H-mode power threshold scaling expressions have been found which incorporates an assumed 1/M isotope dependence for hydrogenic plasmas. Preliminary power threshold predictions based on discriminant analysis have also been made. However, the ITER predictions are still uncertain. The log-linear confinement scaling expressions suggest that the L-mode is governed by Bohm type transport whereas the ELMY H-mode is governed by gyro-Bohm transport. Various non-linear scalings also fit the ELMy H-mode data and a confidence interval for the predicted confinement time in ITER has been established which takes the predictions of these into account.
