摘　　要：随着核电的快速发展,核电站卸载的乏燃料越来越多。为了解决这个问题,国际上提出的处置方法是嬗变,但是MA嬗变的难点是嬗变堆型的选取和如何提高嬗变率。由于压水堆(PWR)是国内外最成熟的堆型和商业运行的主要堆型,也是现阶段最具有可能进行MA嬗变的堆型。于是研究了在压水堆可燃毒物组件中添加MA并利用ORIGEN-S程序进行嬗变计算。通过研究MA嬗变棒的设计、添加位置和添加量等对压水堆堆芯的影响,初步探索出压水堆MA嬗变的设计方案,为我国现阶段进行压水堆MA嬗变奠定了基础。With the development of nuclear power, spent fuel of nuclear power plant is increasing. In order to solve this question, internationally accepted method of disposal is transmutation,but the difficulties of MA transmutation are how to select the type of transmutation reactor and how to improve the transmutation rate. Because of the pressurized water reactor （PWR）is the most mature type of reactor and the main commercial operation reactor type, PWR is the most possible reactor type for MA transmutation at this stage. Therefore,we researched the transmutation characteristics of MA on PWR poison assemblies and we use the ORIGEN-S code to calculate the transmutation rate of MA. We studied the influence of design, layout and loading amount of MA transmutation rod on the reactor core. We explored the design and technology directions of MA transmutation in PWR. The results would lay thefoundation for MA transmutation in PWR.
