摘要

摘要: 一回路注锌技术的应用使得一回路设备表面生成的氧化膜更加稳定，起到降低机组集体剂量的作用。通过分析注锌对机组影响，结合国内某在运压水堆机组注锌目标浓度和现场设备存放条件，设计一套注锌加药设备，明确其设计方案、设备部件参数和工作流程。该设备由溶液混合单元、过滤单元、加药单元及控制单元组成，实现机组运行期间添加醋酸锌和大修期间添加双氧水两种功能应用。

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.
