Abstract

Abstract

The application of primary zinc injection technology makes the oxide film generated on the surface of the primary equipment more stable and plays a role in reducing the collective dose of the unit. By analyzing the effect of zinc injection on the unit, and combining the target concentration of zinc injection in a domestic PWR unit and the conditions of the on-site equipment, a set of zinc injection and dosing equipment is designed, and its design scheme, equipment component parameters and working flow are defined. The equipment is composed of a solution mixing unit, a filtration unit, a dosing unit and a control unit, which can be used to add zinc acetate during operation and hydrogen peroxide during overhaul.
