Development of Nuclear Reactor Core’s Full Offset Refueling Algorithm Based on Two-Dimensional Array

The reactor’s refueling algorithm, which determines safety and efficiency of whole core’s refueling progress, is the key part of manipulator crane control system. This paper presents a new kind of full offset refueling algorithm through reactor core’s modeling based on two-dimensional array. It also resolved significant issues related to the algorithm. The engineering practice shows that the new algorithm can save refueling time prior to ensure nuclear safety, which means bringing considerable benefits to current operating nuclear power reactor station.
