Benchmark on computer simulation of radioactive nuclides production rate and heat generation rate in a spallation target

摘要

The study of ADS operation and maintenance includes also the analysis of the build-up and decay of the spallation target radioactivity and heating, the heating resulting both from the beam particles and from the decay of radioactive nuclides. The aim of the presented benchmark is the selection of the model or code most useful for the ADS calculations and, if such a tool is not yet available, the indication of the main deficiencies of the existing tools. Preliminary results of calculations and their comparison are presented.
