提高压水堆燃耗的经济效益——秦山核电站和大亚湾核电站提高燃耗的前景

Economic Benefits of Increased Discharge Burnup for PWR—Prospect of Increasing Discharge Burnup for Qinshan NPP and Daya Bay NPP

提高卸料燃耗会给电力公司带来很大的经济效益。本文通过作者开发的计算机程序 Dqueco,详细计算了在给定条件下秦山核电站(一期)和大亚湾核电站于12个月循环周期内不同卸料燃耗下的燃料循环总价格及各燃料循环段的价格分量,并指出大亚湾核电站燃耗从33.0 GW·d/t(U)提高到40.7 GW·d/t(U),秦山核电站(一期)燃耗从24.0 GW·d/t(U)提高到32.0 GW·d/t(U)不仅技术可行,而且有很好的经济效益。

Increased discharge burnup brings a great benefits to theutilities.The total fuet cost and its fraction in different fuelcycle activity have been calculated at different discharge burnuplevel and given specific condition byusingDqueco code develo-ped by author himself for Qinsban NPP-1 nad Daya Bay NPP on 12month cycle.It is also pointed that increasing burnup from 33.0GW.d/t(U)to 40.7 GW.d/t(U)for Daya Bay NPP and increasingburnup from 24.0 GW.d/t(U)to 32.0 GW.d/t(U)for Qinsha NPP-1 are not only technically possible,but also economically bene-ficial.
