Measurement and calculation of fast neutron and gamma spectra in well defined cores in LR-0 reactor

Measurement of the23Na(n,2n) cross section in235U and252Cf fission neutron spectra

“…Moreover, there can also be assembled special cores for other types of experiments, like those intended for study of neutronic parameters of new reactor systems coolants or the measurement of spatial distribution of fission density in special arrangements. These special arrangements also have the advantage that they have well defined neutron spectra, which are in the higher energies nearly identical with 235 U fission spectra [4]. The correction to spectral shift between 235 U and reactor spectra is determined calculationally and is 0.965.…”
