Abstract

The third generation advanced pressurized water reactor (APWR) rapid power reduction RPR falling-rod strategy, through RPR falling-rod power reduction and turbine bypass coordination to balance the flow of steam and feedwater, finally solved the problem of turbine shutdown result in reactor shutdown. However, the current RPR rod selection logic is inflexible, the power reduction range is large, restricted conditions are not conducive to the flexible configuration and use of small power reduction conditions. In this paper, the reactor control mechanism, RPR design principle, RPR design problems, need to use conditions, RPR design optimization, simulator verification step by step analysis and deduction. Formed a complete set of optimization design modification measures, and verified.
