ASME CODE PUMPS & VALVES
DRAFT ASME CODE FOR PUMPS AND VALVES FOR NUCLEAR POWER
|Publication Date:||1 November 1968|
The rules of this Code constitute requirements for the design, materials, manufacture, examination, inspection, pressure testing and certification of pumps and valves for use in the nuclear energy system of water cooled commercial nuclear power plants. A nuclear energy system is that part of a power plant that serves the purpose of producing and controlling an output of thermal energy from nuclear fuel.
The scope of these rules covers the strength and pressure integrity of the structure of pumps and valves whose failure would violate the pressure boundary. They are not intended to be applicable to valve operators, controllers, position indicators, pump impellers, pump drives or other accessories and device, unless such items themselves are pressure parts. These rules provide requirements for new construction. They cover mechanical and thermal stresses but do not cover deterioration that may occur in service as a result of corrosion, radiation effects, and instability of material
