Abstract

Periodic pulsed reactors are unique research neutron sources used for experiments in solid state physics, nuclear physics, and radiation research. A reactor of this type represents a dynamic system with multiple feedback loops. Longstanding operation of the BR-2M reactor and its predecessors IBR‑2 and IBR-30 observe unstable pulse dynamics under certain conditions. Several physical feedback phenomena that can lead to unstable dynamics have been discovered and described. In this regard, a software package is being developed to simulate the operation of the reactor taking into account known physical processes, design parameters, and materials of the core in order to study the characteristics of an operating periodic pulsed reactor and design an advanced neutron source. The paper presents a description of the model and results of calculating reactor dynamics.

周期脉冲反应堆的数学模型
周期脉冲反应堆是一种独特的研究中子源,用于固体物理、核物理和辐射研究的实验。这种类型的电抗器代表一个具有多个反馈回路的动态系统。BR-2M反应堆及其前身IBR‑2和IBR-30的长期运行在某些条件下观察到不稳定的脉冲动力学。已经发现并描述了几种可能导致不稳定动力学的物理反馈现象。在这方面,正在开发一个软件包来模拟反应堆的运行,考虑到已知的物理过程、设计参数和堆芯材料,以便研究运行周期脉冲反应堆的特性并设计先进的中子源。本文介绍了反应器动力学的模型和计算结果。
