摘要: 本文结合CPR1000项目中主控室进风γ剂量率监测通道的设计，通过研究相关法规标准，提出了一种主控室进风空气放射性监测的设计方法。首先对测量对象、设备布置、联锁操作进行了描述，然后利用MCNP软件模拟，建立计算模型，探究了该方法下探测器报警阈值的设定，最后结合计算结果给出了该设计的优缺点和改进思路，具有一定的工程实际应用和参考价值。Abstract: According to the design of the main control room intake gamma radiation dose rate monitoring channels in CPR1000 project and the study of relevant regulations and standards, a design method of main control room air inlet radioactive monitoring was presented. The measured object, equipment layout and chain operation were described. The threshold setting was explored using a calculation model established by MCNP software. The advantages, disadvantages and improvement ideas of this design were presented on the basis of calculation results.
