Scope
NB/T 20404-2017 is the English-translated version of RK压水堆核电厂安全壳压力和温度瞬态分析.
NB/T 20404-2017 deals with the analysis of pressure and temperature transients in the containment of a pressurized water reactor.
A break in a high energy line releases steam into the containment and drives its pressure and temperature upward, and the calculated response of the containment sets design conditions for the structure and for the equipment inside it.
The standard belongs to the F65 nuclear power engineering class and is recommended. It quotes NB/T 20403-2017. The documents it cites are GB/T 12727, GB/T 13626, NB/T 20031, NB/T 20056, NB/T 20311, NB/T 20402 and EJ/T 335. Issued on 10 February 2017, it has applied since 1 July 2017.
