Out-of-Pile Experiments Performed in the U.S. Fuel Cladding Chemical Interaction (FCCI) Program

摘要

Since 1972 a variety of out-of-pile experiments have been performed as part of the US National Fuel-Cladding Chemical Interaction (FCCI) Program. In the present paper results from these experiments are presented together with descriptions of many of the experimental techniques employed to obtain them. Although the main emphasis of the paper is on experiments designed to characterize FCCI with Type-316SS cladding, considerable attention is also paid to the following FCCI-related topics: thermodynamics of and phase equilibria in mixed oxide fuel and fission product compounds, fission product and cladding component thermo-transport, and chemical behavior of candidate oxygen-absorber materials (buffer/getters). Detailed interpretations of these results in terms of FCCI mechamisms are presented in a companion paper. (ERA citation 04:056475)
