Power Transfer Functions of the EBWR Obtained Using a Sinusoidal Reactivity Driving Function

Description: A series of reactor frequency response measurements, relating flux or power level to a reactivity input function, were made to evaluate reactor stability for different values of power parameters. These parameters included: power level, steam pressure, and control rod position. The results were extrapolated to predict EBWR stability at higher operating powers. The experimental data may also be used to evaluate the thermodynamic and hydraulic constants. (authl

Radiation Effects on the Oxidation Rate and on Other Chemical Properties of Graphite

Description: Irradiation by fast particles changes most physical and chemical properties of graphite by producing various lattice defects such as displaced atoms, vacancies, dislocations, etc. Attempts have been made to evaluate the contributions of different types of defects to the property changes. Such evaluations have proven rather successful for physical properties and will be extended to several chemical properties. Experiments are described which show that oxidation catalysts and inhibitors act diffe… more
