Abstract
To carry out numbers of survey-type criticality calculations, differential albedos of some reflector materials obtained from ANISN calculation with Hansen-Roach 16 group cross section data are incorporated in Monte Carlo criticality program KENO IV. Although the albedo option is a powerful tool that can save computer time, the above albedo data are not applicable to KENO IV calculation with the multigroup constants libraries MGCL`s (26 group and 137 group) in criticality analysis code system JACS due to the difference of energy structure between MGCL libraries and the 16 group albedo data. A new differential albedo of 30 cm-thick water reflector has been generated by ANISN (P{sub 3}, S{sub 8}, fixed source problem) using 26 group MGCL-J3 for the users of the JACS system. Values of k{sub eff} calculated by the rigorous method and those by the 26 group differential albedo were in good agreement for sphere and infinitely long systems with thick water reflector. For an infinitely long slab system, computer time of KENO IV calculation with the 26 group albedo was 60% shorter than that with the rigorous reflector treatment. (author).
