Prior to analyzing the integral experiments performed at the Fast Neutron Source Facility at the Japan Atomic Energy Research Institute (JAERI), both U.S. and JAERI analysts have agreed on four calculational benchmark problems proposed by JAERI to intercompare results based on various codes and data bases used independently by both countries. To compare codes, the same data base is used (ENDF/B-IV). To compare nuclear data libraries, common codes were applied. The first benchmark problem is a closed Li{sub 2}O spherical geometry surrounding a fusion isotropic point source. A graphite zone and a stainless steel reflector followed the Li{sub 2}O zone. The second benchmark is a series of infinite slab geometries of various thicknesses consisting of natural lithium, Type 316 stainless steel, beryllium, oxygen, lead, and carbon considered individually in the analysis. For each case, an external monodirectional fusion source, incident perpendicularly on the left side of the slab, was considered. An isotropic point source incident on one side of a pseudocylindrical Li{sub 2}O assembly located in a vacuum was used in the third and fourth benchmark problems. Items selected for the intercomparison at various locations in problem 1 are the reaction rates {sup 6}Li(n,{alpha})t (T{sub 6}) and {sup 7}Li(n,n{prime}{alpha})t (T{sub 7}), the fission rate in {sup 235}U, {sup 238}U, {sup 232}Th, and {sup 237}Nb, and the neutron spectrum. The same items were considered in problem 3 and 4. 1 ref., 2 tabs.
