由于采用了集成度高,抗干扰能力强,触发动作阈值高的CMOS组件,使高通量工程试验堆临界装置仪表与控制保护系统有更高的安全性和可靠性。在控制棒驱动线路的设计中,应用了速度负反馈原理,使传动机构电动机转速更加平稳,棒速调整更加灵活。为了进一步保证堆的安全,增设了新的控制线路使在事故情况下,不但带电磁铁的控制棒会快速落棒,其它的控制棒也会以比正常下降快2～6倍的棒速向下插棒。介绍了调试的关键技术和新的抗干扰措施。经过为(4×4-4)核电站燃料元件物理实验而进行的40多次运行,证明该系统的设计、调试是成功和可以借鉴的。
Due to the high level of integrated, anti-interference ability, triggering high threshold of the CMOS components, high-throughput engineering test reactor critical instrumentation and control protection system has a higher safety and reliability. In the control rod drive circuit design, the application of the principle of speed negative feedback, so that the transmission motor speed more stable, more flexible rod speed adjustment. In order to further ensure the safety of the heap, a new control circuit is added so that not only the control rod with the electromagnet will fall quickly in the event of an accident, but also the other control rods will be descended at a rod speed 2 to 6 times faster than the normal descent Insert rod. Introduced the debugging of key technologies and new anti-jamming measures. After more than 40 runs of fuel element physical experiments for (4 × 4-4) nuclear power plants, it is proved that the design and commissioning of this system are successful and can be used for reference.
