摘　　要：目前的化学与放射化学程序和措施,都是针对正常功率运行和按部就班有计划的大修状态而设置,如遇到机组跳堆、跳机或冷停堆等紧急情况,则没有相应的应急预案或相关程序进行提前或有目的地干预。基于这种情况,电厂化学人员经过多年的实践和不断经验反馈,总结并编写了专门针对紧急停机停堆的化学监督与控制应急预案。通过停堆过程和停堆后的不同状态,启机过程的化学与放射化学监测,监督燃料包壳状态,控制一回路的剂量水平,以防止设备腐蚀。During normal operation, a malfunction of equipment or improper operation sometimes results in a turbine trip or reactor scram or even cold shutdown. Because present chemical control strateay and programs aimed at the situation of normal operation and planed refueling outage, no integrate emergency program of radiochemical and chemical control had been developed to focus on this urgent and unexpected situation. After many years of practice and experience feedback, chemists have created an emergency collaborative program of mdiochemical and chemical control which aims at these unexpected situations such as unplanned unit down power, turbine trip, or reactor scram. The program defines different radiochemical and chemical control measures and steps during different status to monitor primary loop dose rate variation, fuel assembly integrity and water chemical excursion to prevent components from corrosion.
