Patent ID: 8185836

Claim:
An apparatus generating a graphical image of a core of a boiling water reactor (BWR) using at least one data set of channel deformation data, said apparatus comprising: a computer system including a display device for presenting the graphical image, a non-transitory storage device storing the at least one data set, and a processor generating the graphical image using the at least one data set; said graphical image of the core includes symbolic representations of control blades arranged in the core, indicia identifying each control blade, and indicia regarding deformation of channels adjacent each control blade, and a viewer software tool stored on the storage device and executed by the processor which accesses the at least one data set and determines a location in the core of the control blades and channels, and correlates and presents the channel deformation data with the channels for display on the graphical image, wherein the viewer software tool identifies surfaces of each channel adjacent to one of the control blades, and includes data regarding an amount of deformation of the identified surfaces towards or away from an adjacent blade of the control blades, and wherein the indicia regarding deformation of each channel surface indicates a degree of deformation of the surface adjacent the corresponding control blade and whether the deformation of the surface is towards or away from the corresponding control blade.
