Error analyses on three methods for experimentally obtaining gap conductance values

PDF Version Also Available for Download.

Description

Gap conductance is a significant factor affecting the stored energy in a fuel rod at the beginning of a hypothetical accident sequence, as well as the thermal and mechanical response of the fuel rod during the accident. Additional well-characterized experimental results are needed to evaluate and improve the current analytical models used to calculate gap conductance during steady-state and transient reactor conditions. The basic difficulty in obtaining the needed data is the inherent uncertainty existing in any experimental method used to determine gap conductance information. The results of error analyses made on three experimental methods are presented and their relative ... continued below
