摘　　要：ADS次临界堆的功率控制与临界堆有本质的不同,临界堆大多以控制棒为控制手段来调节功率,而ADS次临界堆以控制棒和外中子源作为控制手段来调节功率。因此ADS系统的控制更为复杂且具有特殊性,有必要确定ADS次临界堆的控制策略。将控制棒反应性和外中子源强度同时设为受控对象,针对不同的堆芯相对功率偏差下,选择不同的受控对象,实现ADS堆芯功率控制。结果表明:采用切换受控对象的方案比单独以控制棒为受控对象的控制方案具有更优的控制效果。The power control of ADS subcritical reactor is essentially different from that of the critical reactor.The control rod is mostly used as the control means of the critical reactor to adjust power,while the control rod and external neutron source are used as the control means of the ADS subcritical reactor to regulate the power.Therefore,the control of the ADS system is more complex and special.And it is necessary to determine the control strategy of the ADS subcritical reactor.The reactivity of the control rod and the strength of the external neutron source are set as controlled objects simultaneously.Under different core relative power deviations,select different controlled objects to realize the ADS core power control.The results show that the scheme of the switching controlled object is better than the scheme of setting the control rod as the controlled object alone.
