Measurement of the Neutron and Gamma Spectra at the Training and Research Reactor AKR-2
Original language description
The reactor y-ray spectrum is formed by superposition of various sources, namely y-ray spectrum from neutron capture, inelastic scattering or other reactions with their characteristic discrete y rays and a prompt fission y-ray spectrum (PFGS) of fissile materials, which has only continuous component. The main discrete y rays in thermal-neutron reactor have energies below 10 MeV. Due to this fact, one can assume that above 10 MeV the studied y-ray spectrum is nearly identical with 235U(nth., fiss) PFGS, as 235U fission causes more than 99.9 % of total fission in AKR-2. The measurement was performed with scintillation spectrometry using stilbene crystal 45 x 45 mm and newly developed and well validated gamma response matrix. The obtained spectrum is consistent with previous measurements performed in the LR-0 reactor and it is worth noting that a good agreement was reached with the new evaluation used in ENDFB-VIII.0 nuclear data library.
