Abstract:

Using the resonance detectors 115In, Au, 152Sm, 186W, La, Mn, and 98Mo epithermal neutron spectra were studied at various points of the RFR core and in the vertical channel 2 of the RFR thermal column in the energy range 1 to 500 ev with respect to their deviations from 1E behavior. In an air-filled channel at the periphery of the core, alpha 0.98 or - 0.02 was found by an absolute determination. The other measurements have been referred to this value. In the vertical channel 2 of the RFR thermal column distance from the core boundary 60 cm, alpha 1.04 or - 0.02. Author
