- Scope
- This standard specifies the design and layout requirements for safety valves and pressure relief valve piping systems related to the safety of pressurized water reactor nuclear power plants (including active and passive nuclear power plants). This standard applies to the design of safety valves and pressure relief valve piping systems in pressurized water reactor nuclear power plants. The piping system is divided into the following categories: a) Safety valve and pressure relief valve piping system of steam generator; b) Safety valve and pressure relief valve piping system of pressure regulator; c) Except for reactor coolant system and main steam system Piping systems for safety-level safety valves in other systems, such as safety injection systems, waste heat removal systems, chemical and volumetric control systems, equipment cooling water systems, spent fuel pool cooling systems, compressed air systems, liquid waste treatment systems, and passive reactors Core cooling system, etc.
