A time-dependent code for neutron rate interpretation of neutral beam heated tokamak plasmas has been developed. The code is based on a Fokker-Planck model and is comparatively fast. It includes tail-tail fusion reaction rates, which are important but often neglected since they are difficult to calculate. Results from the code are presented for test cases in order to illustrate some of its features. Finally, time-dependent calculations for a JET discharge are presented and the interpretation calculations for the dilution n(D)/n(e) are shown to be in very good agreement with the experimental results.
