This paper reports on neutronics parameters including the source neutron spectrum, activation rates, and the tritium breeding in the Li{sub 2}O test zone of the Fusion Neutron Source Phase II experiment calculated using the Monte Carlo code MORSE with ENDF/B-V transport and reaction cross sections. Favorable comparisons between the measured and calculated results are achieved for the {sup 27}Al(n,{alpha}), {sup 58}Ni(n,p), {sup 93}Nb(n,2n) and {sup 197}Au(n,2n) reactions. Calculated {sup 58}Ni(n,2n) and {sup 197}Au(n,{gamma}) reactions do not agree with measured values within 10 to 40%. For the nickel reaction, the differences may be due to poor data in the ORACT files, while discrepancies for the gold data may be due to unknown quantities of hydrogen-rich epoxy used to coat the Li{sub 2}CO{sub 3} blocks used in the test assembly walls.
