Neutronics deterministic simulations are based on two software components, one dedicated to the unit fuel assembly and the other dedicated to the full core. The more complex one is the lattice code based on a solution of the Boltzmann equation for neutrons and on specific models. It is used for criticality safety and for reactor physics applications by feeding the full core simulation code with a multi-parameter database. In the last 30 years, École Polytechnique de Montréal (EPM) has developed the lattice code DRAGON, now at Version 5, and a 3D diffusion code named DONJON for full core simulations. These two codes are widely distributed across the world under an open-source license and are used by many universities and organizations who are becoming expert users of DRAGON/DONJON.

中子学确定性模拟基于两个软件组件，一个专用于单元燃料组件，另一个专用于整个堆芯。更复杂的一种是基于中子玻尔兹曼方程解和特定模型的晶格代码。它用于临界安全和反应堆物理应用，通过提供具有多参数数据库的完整堆芯模拟代码。在过去的30年里，蒙特利尔理工学院（École Polytechnique de Montréal，简称EMPT）开发了晶格代码DRAGON（目前为第5版）和三维扩散代码DONJON（用于全堆芯模拟）。这两个代码在开放源代码许可下在世界各地广泛分发，并被许多大学和组织使用，他们正在成为DRAGON/DONJON的专家用户。
