摘要： A transiently unstable state of a boiling-water reactor is damped by measuring the oscillating neutron flux and, after a first threshold value is exceeded over a plurality of oscillation periods, the rate of increase of the oscillation is determined. Depending on the slope of the increase, and after a further threshold value (in particular one dependent on the rate of increase) for the oscillating flux is exceeded, a selection is made which one of various stabilization strategies for damping the oscillation should be triggered before a SCRAM becomes necessary. A hierarchy of stabilization strategies is available: blocking a power increase, for instance, in the control system, controlled slow reduction of the power, or rapid power reduction by a "partial SCRAM". The monitoring of the unstable state is effected with a system of sensors strategically distributed throughout the core and which redundantly measure the flux in one region of the core. The sensors act on a plurality of redundantly operating systems, and the signal from each sensor is effective in only one of the redundant systems.
摘要翻译：通过测量振荡中子通量来阻止沸水反应堆的瞬时不稳定状态，并且在多个振荡周期中超过第一阈值之后，确定振荡的增加速率。取决于增加的斜率，并且在超过振荡通量的另外的阈值（特别是取决于增加速率）之后，进行选择，以便在以下触发各种用于阻尼振荡的稳定策略之一： SCRAM变得必要。稳定策略的层次结构是可用的：例如在控制系统中阻止功率增加，控制电力的缓慢降低或通过“部分SCRAM”快速降低功率。不稳定状态的监测通过策略性分布在整个核心上的传感器系统进行，并且冗余地测量核心的一个区域中的通量。传感器作用于多个冗余操作系统，并且来自每个传感器的信号仅在冗余系统中的一个中有效。

摘要： A system for controlling control rods which can be moved into and out of a reactor core of a nuclear power plant, includes a selector device, a monitor device and a rod control device. The selector device contains travel sequences which are selectable and defined for regulating the nuclear power plant, i.e. allocation and movement sequences of the control rods, and it transmits the selector signals allocated to each travel sequence to the rod control device. The monitor device checks the selector signals for acceptability while taking into account the structural features of the reactor core and the control rods, which are allocated to the respective travel sequence, in particular proximity relationships of the control rods. If the selector signals are acceptable, an enable signal is transmitted to the rod control device and the rod control device induces a displacement of the control rods according to the selector signals. From the point of view of process control, the selector device and the monitor device are separate from each other so that the system and method have a high degree of reliability which corresponds to safety regulations for nuclear power plants.
