Although operator actions can prevent the occurrence of and protect the reactor from an instability, the APRM flow-biased reactor scram will suppress power oscillations prior to exceeding the fuel safety limit (MCPR). Reference 3.5.L.2 demonstrated that this protection is provided at a high statistical confidence level for core-wide mode oscillations and at a nominal statistical confidence level for regional mode oscillations. This reference also demonstrated that the core-wide mode of oscillation is preferred due to the large single-phase channel pressure drop associated with the small fuel inlet orifice diameters.
