Scope

This part specifies the methods and stress assessment criteria for stress analysis and seis ic analysis of valves in pressurized water reactor nuclear power plants to ensure the integrity of the valve structure including the pressure-bearing boundary. This section applies to safety-related valves with nominal diameter DN ≥ 25mm. The rules of seis ic analysis are applicable to seis ic-resis ant Class I valves and other valves with seis ic-resis ant requirements. The valve stress analysis rules proposed in this section do not apply to safety valves and pressure relief valves.
