Description
A description is made of the chemical interaction between Inconel spacing grids and the Zircaloy of the sheaths. Experiments performed at 1000, 1100 and 1200 deg C with base Zircaloy and with a previously formed layer of ZrO2, show that the kinetics is parabolic. The difference between both types of experiments is that the oxide layer delays the initiation of the Inconel-Zry interaction. A model is presented, for the description of the solid/solid interaction, which leads to the formation of eutectic that is liquid at the experiment temperature. Also a model, which represents the oxide layer dissolution and predicts the instant in which it disappears completely, is presented. (Author)

En este trabajo se describe la interaccion entre las grillas espaciadoras de Inconel con el Zircaloy de las vainas. Los experimentos realizados a 1000, 1100 y 1200 grados C con Zircaloy desnudo y con una capa de ZrO2 previamente formada muestra que la cinetica es parabolica. La diferencia entre ambos tipos de experimentos reside en que la capa de oxido retarda la iniciacion de la interaccion entre el Zry y el Inconel. Se presenta, por un lado, un modelo para describir la interaccion solido/solido que da lugar a la formacion de un eutectico, liquido a la temperatura del experimento y, por otro, un modelo que representa la disolucion de la capa de oxido y predice el instante en que este se consume totalmente.
