压水堆装载30%MOX燃料的燃料管理及经济性分析

Fuel Management and Economics Analysis on M310 Core with 30% MOX Fuels

初步分析我国现役大亚湾核电站M310堆芯的应用混合氧化物燃料(MOX)组件的可行性及经济性,给出M310堆芯由全堆装载UO2组件向使用30%MOX组件过渡的堆芯燃料管理方案。对使用MOX组件的堆芯的重要参数进行了分析,证明在现役大亚湾核电站M310堆芯应用MOX燃料是可行的。建立经济性分析模型,对所设计堆芯的燃料成本进行了具体分析。结果显示,MOX燃料的引入虽然大大提高了反应堆燃料成本,但仍存在较大的降低空间。

This paper proposes the in-core fuel management of M310 core with 30% MOX fuels and investigates the impact on the key core wide nuclear design parameters.The paper also does some economics analysis of the corresponding fuels.The study shows that loading MOX fuel assembly in M310 is feasible technically.Economics analysis model is established,and the fuel cost for the proposed core is analyzed.The result shows that though the introduction of MOX fuel greatly increases the fuel cost,there exists the possibility to decrease the cost.
