Application of Origen2.1 in the decay photon spectrum calculation of spallation products

摘要: Origen2.1 is a widely used computer code for calculating the burnup, decay, and processing of radioactive materials. However, nuclide library existing reactors like pressurized water reactor, to calculate photon spectrum released by decay spallation products, we have made specific libraries ADS tungsten target, based on results given Monte Carlo code: FLUKA. All data make obtained from Nuclear structure & Data (NuDat2.6). The accumulated activity products contribution nuclides emission are in this paper.
