Description
Activation study is very important for fusion reactors, from the view of component maintenance, occupational radiation exposure, and radioactive waste management. SuperMC is a multi-functional, intelligent, accurate and user-friendly simulation software system with comprehensive functions of transport simulation, material activation and transmutation, radiation source term and dose, etc.
The activation calculation function of SuperMC was developed based on matrix exponential method - Chebyshev rational approximation method (CRAM). The users can specify the material composition and irradiation scenario with friendly user interface. The outputs include general properties, including the density, the composition, the number of stable isotopes, etc; specific activity; decay heat ; contact dose rate ; inhalation dose; ingestion dose; radioactive waste category ; isotopic composition with pathway analysis; decay gamma spectrum.
The program was tested with the handbook of activation data published by EURATOM/UKAEA Fusion and the international activation calculation benchmarks proposed by IAEA. The results show good agreements with the results from EASY. With supports from ITER International Organization, SuperMC was applied in ITER nuclear analysis. It was used to calculate the activation of bio-shield plugs and produce the activation handbook of ITER.
