Activation cross-section libraries for the ORIGEN and ORIGEN-S codes have been generated from the latest Japanese nuclear data library JENDL-5 and JENDL Activation Cross Section File for Nuclear Decommissioning 2017 (JENDL/AD-2017) for activation calculations in nuclear facility decommissioning. The ORIGEN activation cross-section libraries of the 200- and 48-group structures were generated with the AMPX-6 code, while the ORIGEN-S activation cross-section libraries with a MAXS format of the 199-group structure were done with the PREPRO2018 code. In order to verify the generated ORIGEN and ORIGEN-S activation cross-section libraries, activation calculations for Japan Power Demonstration Reactor (JPDR) were carried out in detailed with the DORT, ORIGEN and ORIGEN-S codes, the generated activation cross-section libraries, the ORIGEN and ORIGEN-S bundled activation cross-section libraries, and a JPDR partial model. The following comparisons were performed: 1) the ORIGEN calculation results with the generated activation cross-section libraries and bundled ones, 2) the 200-group and 48-group ORIGEN calculations, 3) the ORIGEN-S calculation results with the generated activation cross-section libraries and bundled ones, and 4) the ORIGEN and ORIGEN-S calculations with the JENDL-5 activation cross-section libraries. Most of the differences of the calculation results were less than 20%, which demonstrated that the libraries were generated adequately. The generated libraries have been released with additional programs from the JAEA website.
