The launch of MCBEND 10.
MCBEND 10 is the latest release of the general radiation transport Monte Carlo code from the ANSWERS Software Service of Serco Assurance. MCBEND is developed within a Nuclear Code Development (NCD) partnership between Serco Assurance and BNFL. The ANSWERS vision is 'to provide easy-to-use software that meets the current and emerging needs of the user community'. In the case of MCBEND, this vision focuses on the key areas of accuracy, understanding of uncertainties, efficiency and user-friendliness. MCBEND 10 is a major launch of the code with many new and enhanced features. New developments in MCBEND 10 include automatic splitting mesh generation, point energy adjoint for neutrons, calculation of uncertainty in the results due to material cross section uncertainties and a unified source facility. Enhanced features include improved temperature treatment, extended scoring of sensitivity to geometry perturbations, geometry improvements, extensions to formulae and improved user guide image. The user-friendliness of the MCBEND code has been further enhanced by recent developments to the visualisation tools, VISAGE and VISTA-RAY. Developments have been made to the three-dimensional visualisation tool, VISTA-RAY, to simplify the detailed checking of a model, with the option to use a mouse-pointer to select regions of interest for further detail and to visually highlight incorrectly defined areas. A further development to VISTA-RAY is the inclusion of the capability to overlay a representation of a user-designated set of results from a MCBEND analysis on the model. Improvements have also been made to the graphical user interface LaunchPad for submitting and controlling calculation submission, with a common user-image across all the systems. Recent enhancements to LaunchPad include a job-scheduler to simplify processing multiple tasks. A selection of the new developments in MCBEND 10, VISTA-RAY and LaunchPad will be described in this paper.
