3. Identification A unique identifier for each benchmark evaluation that takes the form Fissile Material Physical Form Spectrum Three Digit Numerical Identifier such as PU MET FAST 003 for fast plutonium system in which the fissile material is in the form of a metal In the case of subcritical experiments the above identifier string is preceded by SUB such as SUB PU MET FAST 001 for subcritical measurements of metal plutonium systems with fast spectrum This identifier is documented at the top of each page of the evaluation On the Search page this parameter may be set to Critical Subcritical or Critical and Subcritical The subdivision into fast intermediate thermal and mixed spectra systems depends upon the neutron energy range where the majority of the fissions occur In the Handbook fast intermediate and thermal systems are defined as systems in which more than 50 of the fissions occur at energies gt 100 keV 0 625 eV 100 keV and 0 625eV respectively Systems for which more than 50 of the fissions do not occur in any one of these three energy ranges are classified as mixed spectra systems Cross references are included in the ICSBEP Handbook and in DICE for experimental series containing data that may be categorized by more than one energy range For example series MIX MISC FAST 001 is comprised of 11 experiments of which only three configurations Cases 9 10 and 11 are appropriatel
