H-modes have been obtained for the first time in high temperature, high poloidal beta plasmas with significant tritium concentrations in TFTR. Tritium is provided mainly through high power neutral beam injection (NBI) with powers up to 28 MW and beam energies of 90--110 keV. Transition to a circular limiter H-mode has been obtained following a rapid ramp down of the plasma current. Some of the highest values of {tau}{sub E} have been achieved on TFTR during the ELM-free phase of these DT H-mode plasmas. {tau}{sub E} enhancements greater than four times L-mode have been achieved.
