Scope
NB/T 20333-2015 is the English-translated version of 压水堆核电厂一回路安全降压和排气系统设计准则.
The subject of NB/T 20333-2015, a recommended standard of the Chinese energy industry, is the safety depressurization and venting system on the primary loop of a pressurized water reactor nuclear power plant.
It sets the basic design requirements for that system in third-generation pressurized water reactor plants. Operation, maintenance and testing of the system fall outside it, unless they bear directly on the design.
Its field of application is the design of the safety depressurization and venting system of the primary circuit in those plants. It quotes GB/T 17569, EJ/T 335, NB/T 20051 and NB/T 20268, and with the regulatory documents HAF 102 and HAD 102/02. Issued on 2 April 2015, it has applied since 1 September 2015.
