| 中文摘要: |
| 次临界反应堆依靠质子束打靶产生的中子来维持运行,其动态行为与普通临界堆不同.本文建立了铅铋次临界堆芯的动态模型,编写了相应的计算程序,验证了ADS中子动力学模拟的正确性.本文分别模拟了冷却剂入口温度和流量变化对次临界堆的影响.同时,模拟了不同加速器频率下,次临界反应堆的动态响应.结果表明,冷却剂入口温度和流量,均会影响次临界堆的安全运行；选择高频率的质子加速器可以保持次临界堆的稳定运行. |

| Subcritical reactor depends on proton beams interaction with target to maintain reaction.So its dynamic model is different from ordinary critical reactor.In this paper,the dynamic model of the subcritical reactor core was established,and corresponding program was written,which verified the accuracy of the models.The different flow of the coolant and the different temperature of the coolant inlet were chosen to simulate the dynamic characteristics of the lead bismuth subcritical reactor.And,the response of subcritical reactor at different accelerator frequency was simulated.The result shows that,the flow of the coolant and the temperature of the coolant inlet both affect the security operation of subcritical reactor.High frequency proton accelerator can maintain stable operation of reactor. |
