NB/T 20322-2014 is the English-translated version of 压水堆核电厂埋地金属构筑物阴极保护系统调试运行准则.

NB/T 20322-2014 is the recommended Chinese energy industry standard on the commissioning test and the operation of the cathodic protection systems that guard buried metallic structures at nuclear power plants.

It provides the criteria by which such a system is judged compliant during commissioning and during operation at a pressurized water reactor plant. It is written for the buried metal structures of pressurized water reactor nuclear power plants.

It replaces EJ/T 452-1989, the older nuclear industry standard on the same subject. It quotes GB/T 21246, GB/T 50698 and SY/T 0017. Issued on 15 October 2014, it has applied since 1 March 2015.
