摘要： The invention relates to methods for protecting a nuclear reactor core, such as a boiling water reactor core, from fuel and cladding damage due to thermal hydraulic instability in extended operating power flow conditions and, in particular, when an extended power uprate is implemented. The methods employ existing licensed stability methodologies and incorporated minor changes, e.g., to the Average Power Range Monitor (APRM)-based trip system to preclude operation inside the stability vulnerable region of the power/flow map. The APRM-based trip system is modified to set down the APRM flow-biased scram line when core flow is less than a predetermined core flow to prevent the core from entering an unstable region of operation.

摘要： This invention introduces a new method for detecting power oscillations that may occur in Boiling Water Reactor (BWR) cores. According to this invention, the Average Power Range Monitor (APRM) is enabled to detect power oscillations even when the signals from the Local Power Range Monitors (LPRMs) that make up the APRM signal are not in-phase and tend to cancel out. The asymmetric filtering algorithm that is the core of this invention is applied to the individual LPRM signals before they are summed up to make a new APRM signal. The new APRM signal will increase when oscillations occur, regardless of the instability type, and can thus be used for detecting reactor instability and enable the operator or automatic reactor protection systems to actuate and prevent reactor fuel damage.
摘要翻译：本发明引入了一种用于检测沸腾反应堆（BWR）核心中可能发生的功率振荡的新方法。根据本发明，即使来自构成APRM信号的本地功率范围监视器（LPRM）的信号不是同相并且倾向于抵消，平均功率范围监视器（APRM）也能够检测功率振荡。作为本发明核心的非对称滤波算法在将它们相加之前被应用于各个LPRM信号以产生新的APRM信号。无论不稳定类型如何，当发生振荡时，新的APRM信号将增加，因此可用于检测反应堆不稳定性，并使操作员或自动反应堆保护系统能够起动并防止反应堆燃料损坏。
