摘要

本研究旨在探讨钚处理的可行性和钍在此过程中的可用性。为了提高第三代压水堆水-水高能堆（VVER-1200）燃料循环的可持续性，分析了在混合氧化物（MOX）燃料中加入二氧化铵（AmO2）对反应堆性能的影响。研究重点是功率分布、中子通量、无限倍增因子（kinf）、燃料消耗和裂变产物等关键参数。使用Serpent和OpenMC蒙特卡罗代码进行的模拟结果表明，尽管存在一些缺点，但AmO2的添加可以提高反应堆性能，优化燃料使用，并有助于建立一个更可持续和高效的核能系统。

Disposal of large quantities of plutonium and thorium utilization in VVER-1200 reactors using americium-stabilized MOX fuel

This study aims to investigate the feasibility of plutonium disposal and the usability of thorium in this process. The effects of adding Americium Dioxide (AmO₂) to the Mixed Oxide (MOX) fuel content on the reactor performance have been analyzed in order to improve the sustainability of the fuel cycle of the Water-Water Energetic Reactor (VVER-1200), a Generation III pressurized water reactor. The research focuses on key parameters such as power distribution, neutron flux, infinite multiplication factor (k_inf), fuel depletion, and fission products. Findings based on simulations conducted using the Serpent and OpenMC Monte Carlo codes show that, despite some disadvantages, the addition of AmO₂ can enhance reactor performance, optimize fuel usage, and contribute to a more sustainable and efficient nuclear energy system.

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
