Long-term autoclave corrosion tests of stainless steel 08X18H10T and zirconium alloys E110 and Ukrainian pilot calciumthermal Zr1Nb (0.1% O) were carried out in the model coolant environment of WWER reactors with the addition of zinc or aluminum with aim to consider the possibility of using zinc or aluminum addition for improvement coolant on ukrainian WWER reactors. The corrosion kinetics and the condition of the oxide films were studied. It was shown that the addition of zinc improves the protective properties of the oxide films on stainless steels grade 08X18H10T and does not affect negatively on the corrosion resistance of zirconium alloys. The addition of aluminum appeared to be not sufficiently effective. The possible mechanism of the influence of zinc and aluminum on corrosion was considered.
