Solutions of the Reactor Kinetics Equations for Time-Dependent Reactivities

Description: Abstract: The reactor kinetics equations are combined into a single integral equation whose kernel describes the time-dependent characteristics of the reactor including six delayed groups of neutrons. Numerical solutions of the integral equation are given for constant, linear, and ∫sin²kx dx reactivities. An approximate solution of the integral equation is obtained which provides a basis for the formulation and solution of the reactor system control problem using the methods of servomechanisms … more

DETECTION AND TELEMETERING OF IONIZING RADIATION BY FREQUENCY VARIATION

Description: Three methods are discussed for detecting ionizing radiation and transitting the intelligence. All three methods make use of the reactamce variation of a frequency determining network, to vary the frequency of an R.F. transitter as a function of ionizing radiation entering an ion chamber or counter. The first method is based on the capacitance znd subsequent frequency variation of am electrometer incorporated in an ion chamber. The variation is achieved by a moving came electrometer, where the … more

EVALUATION OF WIANCKO AND VIBROTRON GAGES AND DEVELOPMENT OF NEW CIRCUITRY FOR ATOMIC BLAST MEASUREMENTS

Description: Experimental instrumentation was tested on Operation Upshot-Knothole in an endeavor to improve existing blast phenomena measuring equipment and techniques. Experimental designs tested include a field unit oscillatoramplifier using transistor circuit elements, a subminiature two-wire field unit, a commercially developed Vibrotron gage and amplifier unit, and a frequency deviation multiplier circuit for obtaining increased signal-tonoise ratios. The Wiancko pressure gage was also evaluated more f… more
