Summary
This standard specifies the identification method and identification procedures for the second generation of the improved pressurized water reactor nuclear power plant active nuclear three-stage water pump (including equipment cooling water pump, important plant water pump, boric acid pump, spent fuel pool cooling pump and chilled water circulation pump) Documentation requirements. This standard applies to the second generation of improved pressurized water reactor nuclear power plant active nuclear three water pump identification, equipment range covers the pump, bracket, base in the anchor bolts, couplings, bearings, lubrication and sealing systems. Pumps, such as motors, non-metallic parts and materials (lubricants, rings, etc.), mechanical seals, etc. are not within the scope of this standard. Other heap references are used.
