Relative Importance of Temperature, pH and Boric Acid Concentration on Rates of H2 Production from Galvanized Steel Corrosion.

摘要

The corrosion of galvanized steel, to produce hydrogen gas, will occur if sprays operate during a Loss-of-Coolant Accident in a Light Water Reactor. The rates of hydrogen generation, however, are variable and dependent on accident and post-accident conditions. This report describes a study designed to identify the important parameters (temperature, pH, and boric acid concentration) in determining the rates of hydrogen generation from Light Water Reactor containment building spray solutions. The data are gathered over a wide range of temperature, pH, and boric acid concentration, and are used in a two-level, three-factor factorial experiment to determine the relative importance of the three parameters to the hydrogen generation process. A statistical treatment of the data gives an indication of the relative importance of the parameters (temperature, pH, boric acid concentration) and of their interactions. It attempts to fit the data to a relatively simple equation to model the interactions of the various parameters.
