Optimization of Power Ramp Rate in CPR1000 Reactor Restarting

Publish Date: 2019-10-15

Abstract

Abstract

Restart strategy applied in CPR1000 units can be further improved according to the operation experience and the simulation conducted by software. This paper simulates the restarting and full power operating modes of the reactor in terms of ramp rate and Tthreshold power level. Conditioning occurs after tens of hours of operation at full power. The capacity factor can be increased about 0.1% by optimizing the ramp rate.
