The startup of a space nuclear power system is conducted after the space vehicle is put into its operational orbit. The reactor is in a deeply subcritical state, it is technically unfeasible to use a startup source of neutrons, and ground-based operator intervention is excluded. Since payload usage before the nuclear reactor starts is supported by storage batteries, the problem of reducing the startup time and increasing the safety of ground-based adjustments is real for any type of space nuclear power system. In the present article, the methods of optimization of the initial stages of the start-up regime that make it possible to accelerate startup and meet the constraints on the period in ground-based conditions are described. The details of the implementing algorithms are given. Data on the experimental verification of the obtained results are presented.

空间核电系统启动优化方法

空间核动力系统的启动是在航天器进入运行轨道后进行的。反应堆处于深度亚临界状态，使用中子启动源在技术上是不可行的，地面操作人员的干预也被排除在外。由于核反应堆启动前的有效载荷使用由蓄电池支持，因此任何类型的空间核电系统都存在减少启动时间和提高地面调整安全性的问题。在本文中，描述了优化启动机制初始阶段的方法，这些方法可以加速启动并满足地面条件下的周期限制。给出了实现算法的细节。
