Estimation of Hydrogen Peroxide Decomposition Rates in the Boiling Water Reactor Primary Coolant Circuit

In a boiling water reactor primary coolant circuit, the coolant flow velocities and volume-to-surface ratios at various locations are taken into account for the estimation of the decomposition rate of hydrogen peroxide in the system. The decomposition half-times are estimated ranging from a few seconds in the core region to a few minutes in the recirculation piping system.
