Offset-Cardinality Phase Diagram Method of Controlling Reactor Power
- 17 Downloads
The method of routine control of the power release in the VVER-1000 reactor using the offset-cardinality phase diagram is examined. This method minimizes the changes in the local power release accompanying a change in the running values of the reactor power and the axial offset, characterizing the unevenness of the power distribution over the core height. The results of computational validation of the method are presented. The rules for using offset-cardinality diagrams for operating units of VVER-1000 are presented.
