The d(d,p)t and d(d,n)/sup 3/He fusion reactions produce 1 MeV tritons and 0.8 MeV /sup 3/He ions which can subsequently undergo d(t,n)..cap alpha.. and d(/sup 3/He,p)..cap alpha.. fusion reactions. The magnitude of this triton and /sup 3/He ion burnup was measured on the PLT and PDX tokamaks by detection of the 14 MeV neutron and 15 MeV proton emission. In discharges with B/sub phi/ greater than or equal to 2 T, the measured /sup 3/He burnup agrees well with predictions based on classical theories of ion confinement and slowing down, while the triton burnup was about four times lower than theoretically predicted. In discharges with weaker toroidal fields, the burnup of both ions fell by more than a factor of ten.
