[1K09] Test of AMPX multigroup library for shielding in SCALE6.2.1

Keywords:SCALE6.2.1, AMPX multigroup library, self-shielding correction, resolved resonance, unresolved resonance, FRENDY

We investigate whether the self-shielding correction problem for resolved resonances, which was pointed out before, is revised in the AMPX multigroup library (scale.rev12.xn200g47v7.1, neutron 200 groups and gamma 47 groups) for shielding. As a result, it was verified that the self-shielding correction of scale.rev12.xn200g47v7.1 for resolved resonances was not still correct. It was shown the self-shielding correction for unresolved resonances was similar to that with FRENDY, not NJOY.
