摘　　要：在确保安全的前提下,经济性是核电厂的重要目标之一。VVER-1000型反应堆某些非并网运行的工况,如换料后重新临界、热停堆及临界、试验后返临界等操作,在操作所占用的时间、原材料的消耗量以及产生的废水量等方面可作优化。笔者对影响停堆及临界操作的重要因素,即控制棒和硼酸浓度的配置进行定性和定量的分析,得出优化的一般步骤和基本原则,并对3个案例实施了优化。On the premise of safety,economy is one of the important objectives of nuclear power plants.For VVER-1000,there are several cases of operation modes when the plant is off the grid,such as the critical operation after refueling,the hot shutdown and critical operation,and the critical operation after test.For the purpose to reduce the time of the operations,the consumption of materials,and the amount of waste water produced,the optimization researches are carried out on these cases.The qualitative and quantitative analysis is carried out,on the configurations of the control rod and boric acid,which are the important factors to influence the shutdown and critical operations.The general steps and the basic principles of the optimizations are described.Three cases are optimized.
