摘要

PPROBLEM TO BE SOLVED: To start a nuclear reactor safely in a short time even when a neutron flux is dispersed spatially. PSOLUTION: This nuclear reactor output control device 6 for controlling the nuclear reactor is equipped with a reactivity estimation determination part 20 for estimating a local reactivity based on each neutron flux detected by each of a plurality of neutron detectors 4 disposed in a core 2, and determining that the nuclear reactor is in a criticality approaching mode when the maximum value of each local reactivity exceeds a prescribed value, and that the nuclear reactor is in a non-criticality mode in other cases. A control rod extraction quantity calculation part 30 calculates a control rod extraction quantity deviation which is an extraction quantity of the control rod to be extracted per unit time from a difference between the reactivity and a target reactivity. An extraction determiner 41 generates an instruction for extracting the control rod as much as an extraction quantity determined based on a reactor period in the case of the criticality approaching mode, and an instruction for extracting the control rod as much as an extraction quantity determined based on the control rod extraction quantity deviation in the case of the non-criticality mode, and transfers the instruction of control rod operation to a control rod driving control device 9.

要解决的问题：即使中子通量在空间上分散，也要在短时间内安全启动核反应堆。解决方案：该用于控制核反应堆的核反应堆输出控制装置6配备有反应性估计确定部分20，该反应性估计确定部分20基于布置在堆芯中的多个中子检测器4中的每一个所检测到的每个中子通量来估计局部反应性。参照图2，当每个局部反应性的最大值超过规定值时，确定核反应堆处于临界接近模式，在其他情况下，确定核反应堆处于非临界模式。控制杆提取量计算部30根据反应性与目标反应性之差，计算出每单位时间要提取的控制棒的提取量即控制棒提取量偏差。在临界接近模式下，提取确定器41生成用于提取与基于反应堆周期确定的提取量一样多的控制棒的指令，以及与基于反应堆周期确定的提取量一样多的提取控制棒的指令。在非临界模式下，控制杆拔出量发生偏差，并将控制杆操作的指令传送到控制杆驱动控制装置9。
