Abstract A real-time research reactor simulator was developed at the Jožef Stefan Institute for education and training of students and future reactor operators, especially in countries with limited or no access to a research reactor. The research reactor simulator (RRS) simulates time behaviour of reactor power, fuel temperature and reactivity by using the 6-group point kinetics equation with feedback. It features temperature feedback mechanisms and xenon poisoning. Using graphics acceleration to render simulation results and a simple integration scheme with a short simulation step to propagate physics achieves low latency between a user’s input and display of simulation results, which is important for research reactors that can perform fast transients. The simulator targets TRIGA-type reactors, but all physical parameters can be changed on the fly. Thus, the simulator can be easily adapted to simulate other reactors.

基于 PC 的 JSI 研究堆模拟器

摘要 Jožef Stefan 研究所开发了一种实时研究堆模拟器，用于对学生和未来的反应堆操作员进行教育和培训，特别是在有限或无法使用研究堆的国家。研究堆模拟器 (RRS) 通过使用带有反馈的 6 组点动力学方程来模拟反应堆功率、燃料温度和反应性的时间特性。它具有温度反馈机制和氙气中毒。使用图形加速来渲染模拟结果，并使用带有短模拟步骤的简单集成方案来传播物理，实现了用户输入和模拟结果显示之间的低延迟，这对于可以执行快速瞬变的研究反应堆非常重要。模拟器针对 TRIGA 型反应堆，但所有物理参数都可以即时更改。因此，模拟器可以很容易地适应模拟其他反应堆。
