Abstract

Abstract

The configurations of the new closed-loop control system are introduced briefly.The system,served by two computers connected with LAN,is made to control Miniature Neutron Source Reactor（MNSR） which is built in Shenzhen University.The technique measures and design polestars for power control and safety protecting are described in the paper.The measures include the restricting of the built-in reactivity,using right working model with dual control bars,using control-bars dropping system in emergencies,setting the right factors for working/protection/emergencies,and taking the countermeasures for potential risks.The pivotal variables are checked redundantly and could be shared between two computers.This also enhanced the reliability of the system for the reactor.
