摘要
核电厂退役阶段将产生大量的中低放废物。在设计和运行阶段研究和估算退役阶段可能产生的中低放废物总量,可以尽早规划中低放废物的处置场,评估运行阶段所筹集的退役中低放废物的处置费的充足性。文中介绍了利用类比法和统计法计算核电厂退役中低放废物的产生量,结合美国Trojan核电厂和EPR电厂估算的退役产生的中低放废物量,采用类比法分析了CPR1000系列核电厂单堆退役阶段可能产生的中低放废物量。经过分析预计CPR1000系列核电厂退役阶段产生的中低放废物量约为8 000 m^3。
A mass of low-intermediate level radioactive waste will be produced during NPP decommissioning. At the stage of design and operation of NPP,studying and computing the amount of the low-intermediate level radioactive waste of decommissioning will help the owner of NPP to plan the low-intermediate level radioactive waste disposal field as soon as possible,and to evaluate the fund which will be used to dispose the radioactive waste. This paper proposed the methods of analogy and statistics to compute the amount of low-intermediate level radioactive waste, and compared with the amount of low-intermediate level radioactive waste of Trojan NPP and E PR ,and using the method of analogy to compute the amount of low-intermediate level radioactive waste of single CPR1000 NPP. Ac-cording to the analysis,about 8000m3 low-intermediate level radioactive waste will be produced during decommis-sioning of CPR1000 NPP.
