REACTOR MODEL IMPLEMENTATION THE KRSKO EXAMPLE

摘要

COMET, CAE's core model, has been fully described in previous papers (references 3,4). While the principles on which the model is based have not changed over the years, the model implementation has been refined. In addition to the standard one-group implementation, the model is now available with two energy groups. The model also uses core nodalizations of over 2000 nodes. The requirement that simulators must be in phase with reference plants also led to the development of new design/analysis/calibration tools. The most important of these tools, CHORUS, runs off-line in a Windows NT environment. It is used to customize the core model to any specific plant as well as to validate and calibrate the model in background. The real-time extension of CHORUS allows a user to examine, using 2D and 3D plots, any parameters modeled inside the core. The real-time extension was developed in JAVA and can run on any platform supporting the JAVA environment. The subject of this paper is to bring the literature up to date as to the state of core modeling at CAE.
