Solid State Track Recorders have been used to measure absolute fission rates in the Light Water Reactor - Pressure Vessel Simulator at the Oak Ridge Pool Critical Assembly. Measurements were made in the 12/13 configuration with /sup 237/Np, /sup 238/U, and /sup 235/U at the TSF, TSB, PVF, 1/4 T, 1/2 T, and 3/4 T locations. To avoid relative power normalization uncertainties, all locations were measured simultaneously in a single run for each isotope. Comparison of SSTR results are made with the results of measurements performed by NBS and CEN/SCK using benchmark referenced fission chambers and with the trends of theoretical calculations.
