The Tokamak Fusion Test Reactor (TFTR) has been operating safely and routinely with
deuterium-tritium fuel for more than two years. In this time, TFTR has produced a number of
record breaking results including core fusion power,∼ 2 MW/m3, comparable to that
expected for ITER. Advances in wall conditioning via lithium pellet injection have played an
essential role in achieving these results. Deuterium-tritium operation has also provided a

The Tokamak Fusion Test Reactor (TFTR) has been operating safely and routinely with deuterium-tritium fuel for more than two years. In this time, TFTR has produced a number of record breaking results including core fusion power, ∼ 2 MW/m3, comparable to that expected for ITER. Advances in wall conditioning via lithium pellet injection have played an essential role in achieving these results. Deuterium-tritium operation has also provided a special opportunity to address the two years of operation was approximately 40%. Recently the in-torus tritium inventory was reduced by half through a combination of glow discharge cleaning, moist-air soaks, and plasma discharge cleaning. The tritium inventory is not a constraint in continued operations. Recent results from TFTR in the context of plasma wall interactions and deuterium-tritium issues are presented.
