This paper presents an integrated study about some accident-tolerant fuels compared to the standard fuel in trying to find an alternative fuel that enhances the safety, competitiveness, and economics of commercial nuclear power. The neutronic, thermal–hydraulic and solid mechanics analysis of Uranium Nitride (UN) and Uranium Carbide (UC) were performed in a single fuel assembly of the VVER-1000 nuclear power reactor and compared with that of Uranium dioxide (UO₂). MCNPX 2.7 computer code and COMSOL-Multiphysics computer software were used to make a deep analysis for the investigated fuel types. In the neutronic analysis, the fuel burn-up, the safety parameters and the power peaking factor (PPF) for the hot channel were simulated. The thermal–hydraulic and solid mechanics analyses were performed on the hot channel to make sure that the maximum temperature of the clad and the coolant would not exceed the safety limits.

本文提出了对某些耐事故性燃料与标准燃料相比的综合研究，以试图找到可增强商业核电安全性，竞争力和经济性的替代燃料。在VVER-1000核动力反应堆的单个燃料组件中进行了氮化铀（UN）和碳化铀（UC）的中子，热工和固体力学分析，并将其与二氧化铀（UO _{2）进行了比较。}）。使用MCNPX 2.7计算机代码和COMSOL-Multiphysics计算机软件对所研究的燃料类型进行了深入分析。在中子分析中，模拟了热通道的燃料燃烧，安全参数和功率峰值因子（PPF）。在热通道上进行了热-液压和固体力学分析，以确保包层和冷却液的最高温度不会超过安全极限。
