摘要

本文介绍了用于越南大叻核研究堆（DNRR）的实时交互式物理模拟器DalatSim的开发。DalatSim是RELAP5的改进版本，可以动态计算和预测反应堆瞬态。它集成了一个基于SUNDIALS的反应器点动力学求解器，该求解器已根据已发布的基准进行了验证。实验结果证实了该模拟器在模拟正常工况和假设瞬态工况下的操作过程方面的有效性。与记录的DNRR功率数据的比较表明了强烈的一致性。该模拟器旨在支持操作员培训、成本效益教育以及反应堆操作知识和经验的保存。

Development of a real-time interactive physics simulator for the Dalat Nuclear Research Reactor of Vietnam

This paper presents the development of DalatSim, a real-time interactive physics simulator for the Dalat Nuclear Research Reactor (DNRR) in Vietnam. DalatSim is a modified version of RELAP5 that dynamically computes and predicts reactor transients. It integrates a reactor point kinetics solver based on SUNDIALS, which has been validated against published benchmarks. Experimental results confirm the simulator’s effectiveness in modeling operational procedures under normal conditions and hypothetical transient scenarios. Comparisons with recorded DNRR power data demonstrate strong agreement. The simulator is designed to support operator training, cost-effectiveness education, and the preservation of reactor operational knowledge and experience.

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
