The results of a Fokker-Planck simulation of the ripple induced loss of charged fusion products in TFTR are presented. It is shown that the main features of the measured `delayed loss' of partially thermalized fusion products (FPs), such as the differences between deuterium-deuterium (DD) and deuterium-tritium (DT) discharges and the plasma current and major radius dependences, are in satisfactory agreement with the classical collisional ripple transport mechanism. The inclusion of aninward shift of the vacuum flux surfaces turns out to be necessary for an adequate and consistent explanation of the origin of the partially thermalized fusion product loss to the bottom of TFTR.
