Whole process neutronics calculation, in one program
Multi-Functional Program for Neutronics Calculation, Nuclear Design and Safety Evaluation (TopMC, updated and extended version of SuperMC) is a large-scale nuclear design software, which has been developing by FDS Consortium for more than 30 years. Taking radiation transport calculation as the core, TopMC supports the whole process neutronics calculation containing depletion, radiation source term/dose/biohazard, material activation and transmutation.
It is featured with high efficiency and high fidelity multi-physics calculation, accurate modeling, visualized analysis and virtual simulation and intelligent nuclear design and safety evaluation. TopMC can be used for the design and safety evaluation of nuclear energy systems, as well as nuclear technology application fields.
TopMC has been widely used in more than 1000 well-known nuclear-related institutions in energy, healthcare, industry, in more than 90 countries. Related methodologies and technologies have won the National Natural Science Award, the European Prize for Innovation in Fusion Research, etc.
