Scope
NB/T 20070-2012 is the English-translated version of 核电厂安全级电路电缆通道系统设计安装和鉴定准则.
NB/T 20070-2012 is a recommended Chinese energy industry standard on the raceway systems that carry class 1E circuits in nuclear power plants. It lays down the design, installation and qualification requirements for these cable channel systems and also fixes how such a system is to be identified.
It covers the cable channel systems of safety class circuits outside the electrical equipment and components of the plant, without taking aging or irradiation into account, and it does not apply to embedded supports.
It is used with GB/T 13286, GB/T 13625, NB/T 20011 and NB/T 20052, and with the nuclear safety guides HAD 003/04 and HAD 102/11. The earlier document it replaced is EJ/T 590-1991. Issued on 6 January 2012, it has applied since 6 April 2012.
