Measurements made of the Doppler temperature effect for material samples in intermediate and fast spectrum reactors and the experimental technique applied are described. The materials studied in the Be-moderated intermediate reactors were highly enriched U/sup 235/, U/sup 238/, and Hf. In the fast reactors. constructed alternatively of highly enriched U and Al or Pu and Al, experiments were performed with samples of enriched and natural U and Pu. Because of the extremely small magnitudes of the Doppler coofficient in the fast spectrum, only upper bounds could be measured for the effect in the latter experiments. (M.H.R.)
