We developed neutron, photon and electron transport libraries based on JENDL-4.0 for PHITS code. A motivation for the development is to contribute the analysis of the severe accident at Fukushima Dai-ichi Plant. To verify the developed libraries, we carried out test calculations which demonstrate transport of neutron, photon and electron using the libraries. As for the revised Kerma coefficients, we compared them with an ACE-format library based on ENDF/B-VII.1, and checked them visually. The developed photon and electron libraries were compared with MCNPDATA libraries by comparative transport calculations, and bremstrahlung photon spectrum are shown to be consistent with each other.
