Available in PDF, EPUB and Kindle. Book excerpt: The status of the analytic portion of the KEWB program at the time of completion of the spherical core experiments is summarized. Three computer programs were developed for use in this analytic effort. The first reassembles and smooths three decades of reactor power data read separately from oscillogram records of reactor excursions. It then computes the logarithmic derivative of the power, energy release, fuel solution temperature, and temperature compensated reactivity. The second program utilizes the space-independent neutron kinetics equations with any number of delayed neutron groups to determine the reactivity in the reactor from the power and its derivative. The third program solves the space-independent kinetics equations for the neutron flux from an input reactivity or initial period. Up to 50 reactivity feedback equations includirg delayed neutrons are provided for in this program. A mathematical model of the reactor investigated extensively was one containing six delayed neutron groups, conventional treatment of temperature reactivity compensation, and void compensation of reactivity induced by radiolytic gas void growth proportional to the product of reactor power and energy release. Partial mathematical solutions to the kinetic equations were derived for reactivity feedback proportional to prompt temperature and void growth according to the product of power and energy. These solutions apply where delayed neutrons can be neglected, which is the region of major interest. Expressions are available relating power and energy and defining the peak power and energy release to peak power in terms of basic reactor parameters. Experimental evidence, particularly the experimental inlmour curve, of another reactivity influencing mechanism was found present in the reactor at periods shorter than 10 msec. This mechanism was shown to behave as a delayed neutron group, having a mean delay time of approximately 2 msec and an abundance of 2%. A plausible origin of such neutrons was shown to be the reflector which thermalizes core neutrons and returns them to the core following a delay. (auth).

Available in PDF, EPUB and Kindle. Book excerpt: A semitheoretical determination of the percentage change in reactivity of the water boiler per gram of 25 removed from the sphere is presented. The method consists in calculating the external neutron source required to keep level the neutron intensity in the boiler when x grams of 25 are removed from the sphere. Use is made of the experimentally determined neutron-distribution curves. It is found that 18.2 g of 25 subtracted from the sphere produces 1 percent change in K.

Available in PDF, EPUB and Kindle. Book excerpt: A brief review of the theoretical water-boiler reactor-power transfer function is presented as background for the experimental determination of the ratio of effective prompt neutron lifetime to the effective fraction of delayed neutrons, 1/beta. The preparation and performance ot the experiment are discussed with special emphasis on equipment procedures, and measurement errors. The results, which strongly support a seven-delay-group model of the reactor, are presented and compared with theoretical six-and seven-group models. The experiment indicates qualitative values of the seventh-group constants, and it also indicates an 1/beta = 7.7 plus or minus 0.3 msec valid for all but short- period transients. (auth).
