Study on corrosion resistance mechanism by zinc injection into primary coolant
In the primary coolant system of PWRs, various measures are taken to reduce worker exposure. Among these, zinc injection into the reactor coolant has a high effect of reducing exposure by inhibiting the uptake of radioactive cobalt dissolved in the coolant into the oxide film on the piping surface, as well as controlling corrosion of the piping materials. Our company conducts an experimental study on the corrosion resistance mechanism of zinc injection, which has not been clarified in detail, with the aim of further reducing radiation exposure using zinc injection technology.
