For nonlinear stability investigations of nuclear reactor systems, a generalized form of the describing function method is proposed, which allows the calculation of the stability limits and the drawing of general conclusions, whereas known analytical methods lead only to insufficient conditions. The describing function of the nuclear reactor is derived and used mainly to discuss the question of validity of linearizations. As an example, the method is applied to a boiling water reactor (EBWR), considering both linear and nonlinear feedback models. It is found that stability increases as the amplitude of perturbations increase. (auth)
