The estimation of Activated Corrosion Products (ACPs) in fusion technology is an important input to safety assessments (e.g. occupational radiation exposure, accidental analyses). The present work aims to calculate ACPs for the First Wall (FW) and Breeder Zone (BZ) water cooling loops of the DEMO Water Cooled Lithium Lead (WCLL) fusion reactor. The code used is PACTITER v2.1. Geometrical and thermal-hydraulic inputs have been built from the design and operating data of the DEMO-WCLL.

Since an extensive library of experimental data for EUROFER97 corrosion in water is not available yet, correlations obtained from previous calculations have been employed and compared to measured values.

The impact of operational scenario and water chemistry conditions is here shown. Preliminary results confirm the preference towards a water chemistry of pH = 7.0 at 300 °C. The continuous scenario provides the most conservative results in terms of mass and activity inventory for ACPs.

聚变技术中活性腐蚀产物（ACP）的估计是安全评估（例如职业辐射暴露，意外分析）的重要输入。本工作旨在计算DEMO水冷锂铅（WCLL）聚变反应堆的第一壁（FW）和繁殖区（BZ）水冷却回路的ACP。使用的代码是PACTITER v2.1。根据DEMO-WCLL的设计和运行数据建立了几何和热工液压输入。

由于尚没有关于EUROFER97水中腐蚀的大量实验数据的资料库，因此采用了从先前计算中获得的相关性，并将其与测量值进行了比较。

此处显示了操作方案和水化学条件的影响。初步结果证实，在300°C时偏爱pH = 7.0的水化学。就ACP的数量和活动清单而言，连续情景提供了最保守的结果。
