STATISTICAL ANALYSIS AND MODELING OF GAP CONDUCTANCE DATA FOR REACTOR FUEL RODS CONTAINING UO2 PELLETS

PDF Version Also Available for Download.

Description

The purpose of this study was threefold: To examine a large body of in-reactor data for UO{sub 2} pellet fuel where internal temperatures have been measured, and to estimate fuel surface temperature, cladding inner temperature, and thus gap conductance under a consistent set of assumptions. To estimate the variance (due to experimental uncertainties) in the inferred gap conductance values. To attempt a correlation of the gap conductance values with design parameters and operating conditions (e.g., with cold diametral gap and local linear power).
