A THERMAL ANALYSIS OF ZIRCALOY FUEL-ELEMENT CONTAINERS FOR THE NS SAVANNAH REACTOR

Zircaloy is considered as a substitute for stainless steel in the fuel-element containers for the N.S. Savannah reactor. A thermal analysis was performed to determine the temperature distributions in the Zircaloy fuel-element container walls and spacer bars; these temperature distributions were obtained primarily for use in evaluating thermal stresses. The equations for temperature in the fuel-element coolant, control-rod coolant, and container walls were derived. Gamma-roy energy deposition rates in the Ziracaloy components were calculated. Three-dimensional temperature distributions in the spacer bars were obtained from numerical solutions of the heat-conduction equation. Results are presented in the form of temperature-profile curves for each component and for three reactor operating conditions.(Author)
