Neutronics analysis for the TFTR Lithium Blanket Module (LBM) design included 1-D, 2-D, and 3-D exploratory calculations culminating in reference noncoupled and coupled Monte Carlo calculations of fluxes, tritium production, and foil responses throughout the module for both D-T and D-D plasmas. ,Neutron flux and tritium production were shown to be quite flat across the module, validating the choice of a 10-cm-radius central test region. A Monte Carlo perturbation routine was extensively used for modeling studies. The front-face fusion fluence and central region tritium production can be calculated to better than ±15% uncertainty overall.
