Nuclear power plant filters are classified as "nuclear - grade equipment," with their core application centered on intercepting radioactive particles and ensuring extremely high reliability.

• Primary circuit (control rod and coolant) filtration
  • Application: Utilizes sintered metal filter elements or special glass fiber filter elements.
  • Purpose: Intercept tiny corrosion products (crud) and worn metal particles in the coolant. This serves to protect the main pump and prevent these particles from entering the reactor core, where they could become highly radioactive sources through irradiation.
• Spent fuel pool and reactor pool water purification
  • Application: Employs large - flow deep - bed filter elements.
  • Purpose: Physically remove suspended impurities in the pool water, maintain water transparency (for easy observation during lifting operations), and control the total radioactivity level.

The challenge for hydropower plants stems from the open nature of the water source, and physical filtration focuses on resisting sediment abrasion and enabling automated operation and maintenance.

• Technical Water Supply System (Cooling Water)
  • Applications: Automatic backwashing filters, rotary screen filters.
  • Direction: Large quantities of river water are required for cooling the turbine bearings and generators. Physical filters are responsible for intercepting sediment, leaves, shellfish, and other impurities to prevent cooler blockage and subsequent overheating and shutdown of the unit.
• Turbine Main Shaft Seal Water Fine Filtration
  • Applications: Dual - cylinder switching filters.
  • Direction: Physically filter out extremely fine sand particles (micron - sized) to prevent abrasion of the seals by sand particles during high - speed rotation, extending the lifespan of the main shaft seals.
