Frequency Response Testing in Nuclear ReactorsT Kerlin Frequency Response Testing in Nuclear Reactors presents the optimum testing procedures for measurements in power reactors. This eight-chapter book emphasizes the determination of the system frequency response using nonsinusoidal input perturbations, which are useful since normal power reactor hardware can be used. This text deals first with the mathematical aspects of frequency response testing, with a particular emphasis on numerical Fourier transformations using analog or digital equipment. The subsequent chapters examine the important signals for use in frequency responses tests and the analysis of these signals using analog and digital computing equipment. The discussion then shifts to the frequency response functions that describe nuclear reactor dynamics. This topic is followed by a presentation of techniques for extracting useful information from test results. A chapter highlights the most common control-rod drive mechanisms to assess their suitability for dynamics testing. The concluding chapter provides a brief summary of significant experiences with dynamics tests in nuclear reactors. Scientists, researchers, and workers in the field of nuclear reactors and related subjects will find this book invaluable. |
