Dissolution and deposition at the surface of authentic PWR primary circuit corrosion product oxide: results for cobalt and manganese at 3000C
Description
Metal oxides dissolve and deposit around the primary circuit of a PWR. These processes are widely believed to be responsible for the net transport of corrosion products from one part of the circuit to another and for the transport of radioactivity from the core to out-of-core radiation fields at shutdown. In this report, results are given for the rates at which cobalt and manganese dissolve from and deposit on a sample of authentic corrosion product collected from the primary circuit of an operating PWR. The report discusses the effects of solution pH and boric acid concentration on equilibrium solution concentration and rates of dissolution and deposition at 3000C. (author)
