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
