WIMS provides a wide varietyof easy-to-use methods (both deterministic and Monte Carlo) coupled with modern nuclear data and can be used for both benchmark and design type calculations in two and three dimensions.
WIMS can provide modelling capabilities ranging from a simple pin cell calculation of reactivity to whole core estimates of power and flux distributions. All fast and thermal reactor types, including research reactors, can be analysed. The user can benefit from the flexibility of predefined calculation routes or customised methods of solution using diffusion theory, discrete-ordinates, collision probability, characteristics or Monte Carlo methods.
Due to its open modular structure, WIMS can be used in a wide variety of modes. This range of options and the capability to build different calculation routes within one code system mean that almost all types of reactor core calculation can be specified within WIMS. WIMS has an easy to use input syntax and is backed up by a comprehensive range of introductory and reference documentation, including an easy to follow User Guide including numerous worked examples.
WIMS has been successfully used in support of the design and operation of a wide range of nuclear reactors. Selected examples include:
WIMS is supported by Visual Workshop which provides geometry viewing and results display functionality.
WIMS is available for both Windows and Linux
