MONK® is a powerful Monte Carlo software tool for nuclear criticality safety and reactor physics analysis
MONK's advanced geometry modelling and detailed continuous energy collision treatment provides realistic 3D models for an accurate simulation of neutronic behaviour. MONK's superhistory algorithm provides robust and reliable estimates of the neutron multiplication factor, k-effective and other parameters of interest.
Nuclear data libraries exist for MONK from a variety of sources including JEFF, ENDF/B-VII, CENDL and UKNDL. These exist in continuous-energy and hyperfine group form for definitive criticality analyses and in multigroup form for reactor analysis. A microscopic depletion capability is available.
Validation is of prime importance for a criticality code and the MONK package contains a large set of validation data, drawing heavily on experiments in the International Criticality Safety Benchmark Evaluation Project (ICSBEP) handbook. Support in the use of the code and its application is available from our dedicated help-desk, providing direct access to our criticality, reactor physics and shielding expertise.
MONK has been successfully used in support of the design and operation of a wide range of nuclear facilities covering the complete fuel cycle. Selected examples include:
MONK is supported by Visual Workshop, which means that checking for geometry errors is easy.
MONK is available for both Windows and Linux
