Reaction rate distributions and related data in the FNS Phase II experiments
Neutronics parameters including the source neutron spectrum, activation rates, and the tritium breeding in the Li{sub 2}O test zone of the Phase II experiment performed at JAERI have been calculated using the Monte Carlo code MORSE using ENDF/B-V transport and reaction cross-sections. Favorable comparisons between the measured and calculated results have been 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 did not agree with measured values within 10--40%. For the Ni reaction the differences may be due to poor data in the ORACT files while discrepancies for the Au 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. The calculated tritium breeding in the Li{sub 2}O agreed with experimental values within {plus minus} 10% for {sup 6}Li and {plus minus} 15--20% for {sup 7}Li.
