An improved triton burnup code, using the measured shot-to-shot plasma parameters and profiles, is used to recalculate the ratio of 14 MeV to 2.5 MeV neutron fluences under the assumption of neoclassical slowing down. This neutron fluence ratio is compared with the experimental fluence ratio from the FT tokamak for various toroidal magnetic fields and plasma currents. The accuracy achieved in the calculations permits a better evaluation of the confinement of fusion produced tritons during slowing down in FT Ohmic plsma. Assuming a current distribution J(r) ∼ Te3/2, it is found that the confinement is neoclassical, within the accurary given by the error bars, but a deterioration is observed for decreasing q(a). When the Kadomtsev sawtooth model is used for the current distribution, such a deterioration does not seem to occur.
