Phaeton Project

摘要

The objective of project PHAETON is a reduction of the shutdown margins associated with an inaccurate appreciation of actual core conditions throughout the cycle. This lack of accuracy primarily affects, at some of the fuel pellets, the values of local parameters which determine the safety criteria ensuring fuel rod integrity: local power, and, local burnup. The four-processor demonstrator has shown the feasibility of providing power plant sites with microprocessor-based computers. Such computers combine high capability and low cost. In its future version, it should permit on-line computation of the three-dimensional flux distribution, with fitting to in-core measurement data at one-minute intervals. (ERA citation 12:026741)
