NB/T 20267-2014 is the English-translated version of 核电厂计算机化运行规程系统设计准则.

NB/T 20267-2014 is the recommended Chinese energy industry standard covering the design of computer-based procedure systems in nuclear power plants. It sets out guidelines for the computerization of plant operating procedures, from design and implementation through to the operation and maintenance of the resulting system.

Its scope reaches the design and development of the computerized human-machine interface through which operators follow those procedures. The text is a non-equivalent adoption of IEC 62646-2012 and carries the Chinese classification F65 and the international classification 27.120.20.
