Fusion energy has promised clean, secure energy for many years and important advances are expected in the next couple of years from the US National Ignition Facility. If the UK is to play a significant role in a subsequent international collaboration for an Inertial Fusion Energy demonstrator we need the ability to make independent target designs and assessments.A key component of this which has been lacking in the UK academic area is a multi-dimensional computer model which follows the hydrodynamic evolution of the laser targets through absorption of the laser energy, ablation, implosion and thermonuclear burn. RALF (Radiation-hydrodynamics using ALE methods for Fusion) will lay the foundation for this capability in a two year project which can then grow quickly if required for participation in a major project. RALF is designed to be a scalable parallel computer model capable of being run in 3D on large High Performance Computing (HPC) installations. RALF is a collaboration between the University of Warwick and Imperial College and continues an area of collaboration begun with the EPOCH code and the Collaborative Computational Project in Plasma Physics (CCPP). RALF will benefit from close links and advice from AWE Aldermaston where there is a growing activity in Inertial Fusion Energy for power production.

Fusion Energy已承诺要清洁，安全的能源已有多年了，并且预计未来几年将从美国国家点火设施中获得重要的进步。 If the UK is to play a significant role in a subsequent international collaboration for an Inertial Fusion Energy demonstrator we need the ability to make independent target designs and assessments.A key component of this which has been lacking in the UK academic area is a multi-dimensional computer model which follows the hydrodynamic evolution of the laser targets through absorption of the laser energy, ablation, implosion and thermonuclear burn. RALF（使用ALE方法进行融合的辐射流动力学）将在为期两年的项目中为该能力奠定基础，如果需要参加大型项目，则可以迅速增长。 RALF设计为可扩展的并行计算机模型，能够在大型高性能计算（HPC）安装中以3D运行。拉尔夫（Ralf）是沃里克大学（Warwick）和帝国学院（University of Warwick）和帝国学院（Imperial College）之间的合作，并继续从《时代守则》（Epoch Code）和等离子体物理学（CCPP）的协作计算项目开始。 Ralf将从Awe Aldermaston的紧密联系和建议中受益，在惯性融合能源的发电能源活动中的活动不断增长。
