摘要
鉴于近年来提升功率在大量现役核电厂中的成功应用,以及长周期、高燃耗、低泄漏的堆芯燃料管理技术所带来的更高的燃料利用率,本文对现役30万千瓦核电厂基于提升功率下开展了长周期、高燃耗、低泄漏的堆芯燃料管理方案研究。本文初步设计的燃料管理策略在满足有关的设计准则和要求基础上,可满足堆芯额定热功率为1 250MW的18个月长周期的堆芯燃料管理目标。与现行的堆芯燃料管理方案相比,可使核电厂在提升功率的同时进一步提高燃料利用率,经济性得到显著提高。本研究作为一项技术支持和技术储备,对30万千瓦级核电厂的功率提升和燃料管理方案优化具有较强的指导意义。
In recent years, power uprate is successfully applied in many nuclear power plants. Moreover, a longer cycle, higher uprate burnup and lower leakage fuel management strategy could enhance the fuel utilization. Therefore, the purpose of this article is to study a longer cycle, uprate burnup and lower leakage fuel management {or a 300MWe NPP after power uprate. The results show that the concluded fuel management scheme for a 300MWe NPP after power uprate achieves the projected 18- month refueling cycle design objectives with the nominal thermal power of 1 250 MW and meets the design criteria. As compared to the current fuel management strategy of a 300MWe NPP, the advanced strategy in present study gains a power uprate, enhances the fuel utilization and improves the operation economy. As a technical support and reserve, the study will provide significant instructions on power uprate of a 300MWe NPP and optimization of fuel management strategy.
