NB/T 20373-2016 Passive pressurized water reactor nuclear power plant engineering design graphics symbols and text codes

Scope

This standard specifies the styles and usage of graphic symbols and text codes for the engineering design of AP/CAP series pressurized water reactors. This standard is applicable to the drawing of pipeline and instrumentation flowcharts, three-dimensional diagrams (axonometric diagrams) of pipelines, electrical system diagrams, single-line diagrams of electrical systems, electrical wiring diagrams, electrical floor plans, communication system diagrams, communication floor plans, logic diagrams, and functional diagrams for AP/CAP series pressurized water reactors. Other pressurized water reactors can refer to and use it for reference.
