Description
In order to check the existing nuclear data files such as ENDF/B-IV, ENDL, JENDL-3 etc., neutron leakage spectra from various kinds of sphere piles have been measured using the intense pulsed neutron source at OKTAVIAN and time-of-flight techniques. Measured samples include LiF, TEFLON: (CF2)n, Si, Ti, Cr, Mn, Co, Cu, As, Se, Zr, Nb, Mo and W. The obtained data were compared with the theoretical calculations using two kinds of transport codes, ANISN or MCNP and the evaluated nuclear data files, ENDF/B-IV, JENDL-3T and ENDL. ENDF/B-IV and ENDL data contain several problems resulting considerably large disagreement in the spectra for LiF, TEFLON, Cr, Mn, Co, Cu, Nb, Mo and W. JENDL-3T data gave preferable calculated spectra to the ones from other data. (author)
