The PHITS code is applied to neutronic calculations for the high flux test module in IFMIF. The neutron energy spectrum and heating rate calculated with the Li(d,xn) neutron source term obtained by the McDelicious code reproduce the FZK result fairly well. The sensitivity of three nuclear data libraries (LA150, NRG-2003, and JENDL/HE-2004) to nuclear heating calculation and the validity of KERMA approximation are discussed. A new nuclear data evaluation of the d + Li reaction is proposed on the basis of an advanced model calculation with a continuum-discretized coupled-channels (CDCC) method. A preliminary CDCC analysis of deuteron elastic scattering from Li is presented.
