摘要/Abstract

摘要： 为了便于国内核电厂进行较为深入的腐蚀产物产生、分布和控制措施等研究,对腐蚀产物的产生和物理特性、CORA程序的原理及使用范围、国际上采用CORA程序对核电厂腐蚀产物控制措施的情况、辐射场监测和集体剂量分析等方面的经验进行了研究,并采用CORA程序对AP1000核电厂主要的腐蚀产物控制措施进行了分析。通过研究得出如下的结论和建议:CORA程序适用于当核电厂设计条件发生变化时,对电厂中腐蚀产物的影响进行评估;国外广泛采用CORA程序应用于核电厂辐射场测量和腐蚀产物控制措施研究中;CORA程序计算可说明AP1000核电厂中采用的主要控制腐蚀产物的措施,如控制蒸汽发生器传热管钴含量、提高向反应堆冷却剂中注入的LiOH浓度等措施对于控制腐蚀产物是有效的;建议国内核电厂广泛应用CORA程序以研究电厂中辐射场的变化及腐蚀产物的控制措施。

Abstract: In order to develop deep research on corrosion products generation, distributions and control measures in China, the contents include corrosion products generation physical characteristic, principles of CORA code and code applicability, control measurements and radiation field research held by CORA code, and the collective dose analysis were introduced in this article. Moreover some conclusions and suggestions were introduced in this article:1, CORA code is applicable as well when the design condition changes; 2, CORA code is a popular worldwide method to analyze the plant radiation field and corrosion products control measurement; 3, the measurements of controlling the Co concentration in the U-tubes in SGs, increasing the LiOH concentration in the reactor coolant are effective for the corrosion products control. In addition, CORA code is strongly recommended for the plant radiation field and corrosion products control analysis.

Key words: corrosion products, collective dose, CORA code, radiation control measurements
