Abstract

The overhaul optimization of CPR1000 unit is an effective and important way to reduce operating costs, improve unit availability and core competitiveness, and shorten the overhaul period and reduce overhaul costs are the requirements of nuclear power development planning. In this study, the constraints of flow improvement in the oxidation purification stage of CPR1000 unit during the overhaul period were simulated and analyzed, and the pressure distribution at different positions after the flow increase, the relationship between pressure difference and flow of the equipment, and the margin of pressure valve adjustment were analyzed to achieve the increase of oxidation purification flow and the great shortening of purification time. The calculation and analysis of this study show that the existing equipment of the oxidation purification circuit has the prerequisites for flow improvement, but the reliability of the filter and desalination bed needs to be further verified, and the overhaul period can be saved by 3.84~7.88 h after the flow rate is increased to 40 m³ /h.
