Tritium production in a sphere of [sup 6]LiD with an Oralloy core irradiated by a central source of 14-MeV neutrons has been calculated and compared with experimental measurements. The experimental assembly consisted of an Oralloy sphere surrounded by three solid [sup 6]LiD concentric shells with ampoules of [sup 6]LiH and [sup 7]LiH located in several positions throughout the assembly. The Los Alamos Monte Carlo Neutron Photon Transport Code (MCNP) was used to calculate neutron transport through-out the system and tritium production in the ampoules. The MCNP calculations were three-dimensional and employed ENDF/B-V cross sections. The overall experimentally observed-to-calculated ratios of tritium production were 0.996 ([plus minus]2.5%) in [sup 6]LiH ampoules and 0.903 ([plus minus]5.2%) in [sup 7]LiH ampoules. Tritium production in a sphere of [sup 6]LiH without an Oralloy core has been reanalyzed using ENDF/B-V cross sections, and the results are reported. The reanalyzed observed-to-calculated values of tritium production were 1.053 ([plus minus]2.1%) in [sup 6]LiH and 0.999 ([plus minus]2.1%) in [sup 7]LiH. The foregoing several uncertainties do not include an estimated [lt]6% systematic error in the observed values.
