Abstract
A nuclear reactor core performance data visualization system provides a method and apparatus for extracting and visually displaying large amounts of numerical performance data acquired from an operational nuclear reactor or from a nuclear reactor core simulator. The visualization system apparatus includes a color display device, a digital computer having a data storage memory, and one or more data communications links for communicating with reactor core sensors and/or other computers. After acquiring performance parameter data, the visualization system computer extracts selected performance data and constructs two distinct data arrays in memory that are used in creating formatted files for generating specific types of visual displays. A first data array, containing time-varying reactor performance parameter data corresponding to the performance of reactor core elements in two dimensions over a predetermined duration of time, is used, to create digital image animation files for displaying dynamic color-coded graphics, including reactor core element diagrams and multi-ordinate graphs. Once animated, the displayed graphics allow the user to view a time-wise evolution of the changing numerical values for selected core parameters and other time-dependent variables. A second data array, containing spatially-related core performance parameter data corresponding to performance of reactor core elements in three dimensions at one or more selected point(s) in time, is used to create virtual reality modeling language (VRML) files for displaying a virtual 3-D color-coded reactor core model that can be manipulated in three dimensions by the viewer.
