We are focusing on full-core reactor physics codes required for simulation of operation, fuel management and safety analyses of third- and fourth-generation reactors. Neutron diffusion theory is currently used for this purpose, but reference calculations require a more accurate representation of transport phenomena. Based on recent advances related to the MOC and to the evolution of computer clusters, we can now propose the implementation of a family of rigorous full-core solution technique relying on the discrete ordinates method (for regular geometries) and on the MOC (for unstructured geometries). The MOC we propose to develop is an original contribution based on:

我们专注于第三代和第四代反应堆运行模拟、燃料管理和安全分析所需的全堆芯反应堆物理代码。中子扩散理论目前用于此目的，但参考计算需要更准确地表示输运现象。基于与MOC相关的最新进展和计算机集群的发展，我们现在可以提出一系列严格的全核解决技术的实现，这些技术依赖于离散坐标方法（用于规则几何）和MOC（用于非结构化几何）。我们建议开发的MOC是基于以下方面的原创贡献：
