XIMAGE is a graphical fuel management and loading pattern optimization suite that provides core design engineers with a sophisticated interface to simplify fuel shuffling and the evaluation of alternative loading patterns.
Point-and-click access to the most widely used core design and analysis applications.
Seamless coupling to Studsvik’s industry-leading core analysis neutronic system.
Explore deeper into the core design space to find cost-saving solutions.
XIMAGE contains an impressive array of intelligent automation for the most widely used core design and analysis applications:
XIMAGE also includes tools not available in any other core design software, such as a multi-cycle framework allowing detailed design of individual core designs within a sequence of scoping cycles and a highly configurable “autoloader” to automatically generate patterns that satisfy core design requirements like cycle length and margin to thermal limits.
Leveraging the power of CASMO and SIMULATE, Studsvik’s industry-leading nuclear reactor analysis software, XIMAGE provides robust core design evaluation utilizing the same 3D core models used in other areas of the plant. The XIMAGE graphical interface utilizes several SIMULATE physics models, including cross-section feedback and pin reconstruction, for optimal accuracy.
The powerful neutronic engine running within XIMAGE means that the final core design can be immediately handed to other engineers for analysis with other Studsvik software tools without any additional effort.
XIMAGE can assist core design engineers with a variety of tasks, giving organizations the power to perform their own independent fuel design analyses:
What is the impact on cycle length and thermal margin? Can those requirements be met with fewer bundles using a better core design?
The ability to quickly explore a wide range of core designs can lead to a better core design that still meets safety margins.
XIMAGE has been applied in core design studies for virtually every PWR fuel and core design in existence today. Whether the fuel is high- or low-enriched, uranium or MOX, contains erbia, gadolinia, or IFBA poisons; XIMAGE has been successfully used to improve the core design process.
The optimization module of XIMAGE/ SIMAN-PWR generates high quality loading patterns by combining simulated annealing- based optimization algorithm with accurate neutronic analysis of each candidate pattern.
Optimization is subject to geometric heuristics and user-defined loading pattern rules in order to improve core performance relative to specific objectives and constraints, like pin power peaking, moderator temperature coefficient, and pin exposure.
