【 摘 要 】

This report documents the MCWO-calculated Zr-cladding fast neutron fluence (E > 0.1 MeV and E > 1.0 MeV) distributions at the end of each cycle (127C to 132C) during the irradiation Phase-IV-2 (50 GWd/t) using the detailed ATR quarter core model calculated neutronic tallies. The integrated Zr-cladding fast neutron fluence distributions are tabulated in Tables 1 to 9. At the end of the Phase-IV part-2 irradiation, the MCWO-calculated Zr-cladding fast neutron fluences (E > 1.0 MeV) of the removed MOX capsules 5, 6, and 12 are 1.71, 1.68, and 1.68 x 1021 n/cm2, respectively.
