脉冲堆控制保护系统设计

The Design of Plused Reactor Control and Protection System

脉冲堆有手动、自动、方波和脉冲4种运行方式。对应每种运行方式,提供相应的测量通道并对重要参数进行指示和记录,使操纵员获得必要的信息。保护系统和联锁为反应堆安全运行提供保证。保护系统监测少数几种参数并对测量值进行处理和逻辑选通,以确保反应堆在事故工况时的安全。功率调节系统能实现:以恒定周期升功率和恒速降棒降功率。这样,在启堆或变功率运行时,操纵员只需板动定值开关,堆功率即能自动跟踪定值功率。

There are four modes of operation for the pulsed reactor. They are manual, automatic, square-wave and pulse mode. Measuring channels are offered corresponding to each of the four modes. Some important parameters are recorded and indicated, from which the operator can get the information nessecery. The protection system and interlock ensure the safety for the operation of the reactor. The protcction system monitors a few kind of parameters. The data received are processed and gated ensuring the safety of the reactor in accident conditions. The regulation system can rise the power according to a constant period or reduce the power by dropping the control-rod in a constant speed. Thus the power of the reactor will follow the preset power level while operator turned the preset-switch, when start-up the reactor or change power level in operation.
