EXTRAPOLATION OF RATE CONSTANTS OF REACTIONS PRODUCING H_2 AND O_2 IN RADIOLYSIS OF WATER AT HIGH TEMPERATURES

摘要

One target of our research is to extrapolate known data on the rate constants of reactions and add corrections to estimate the rate constants at the higher temperatures reached by the SCWR reactors. The focus of this work was to extrapolate known data on the rate constants of reactions that produce Hydrogen or Oxygen with a rate constant below 10~(10) mol~(-1) s~(-1) at room temperature. The extrapolation is done taking into account the change in the diffusion rate of the interacting species and the cage effect with thermodynamic conditions. The extrapolations are done over a wide temperature range and under isobaric conditions.
