Filtration Solutions for Pressurized Water & Heavy Water Reactors (PWR & PHWR)
Protecting reactor systems and personnel with advanced filtration for PWR and PHWR operations
Engineered for Safety, Reliability, and Compliance
Pall Corporation delivers high-performance filtration systems tailored for Pressurized Water Reactors (PWR) and Pressurized Heavy Water Reactors (PHWR). Our solutions reduce radioactive exposure, protect critical components, and support compliance with global safety standards.
Filtration Applications by Reactor Diagram Point
Each numbered point on the PWR/PHWR reactor diagram corresponds to a critical filtration system. The table below outlines the system name, its purpose, and Pall’s recommended filtration solutions which is designed to reduce radioactive exposure, protect equipment, and meet global safety standards.
| Diagram Point | System Name | Application & Purpose | Shop Product |
|---|---|---|---|
| 1 | Residual Heat Removal (RHR) Systems | Protect ion exchange beds from fouling and abrasion; safeguard mechanical seals and bearings during shutdown | |
| 2 | Chemical Volume Control System (CVCS) | Remove irradiated particulates and resin fragments; protect reactor coolant pump seals and demineralizer beds; reduce out-of-core radiation levels | |
| 3 | Turbine Lubrication & EHC Systems* | Maintain oil quality and cleanliness; remove water, acid, and varnish from turbine lube oil and phosphate ester fluids; protect bearings and hydraulic controls | |
| 4 | Condensate System | Remove suspended solids and corrosion products; protect steam generators; reduce chemical treatment and deep bed regeneration | |
| 5 | Waste Water Treatment | Filters radioactive waste streams; removes suspended solids and resin fines; supports safe discharge and regulatory compliance | |
| 6 | Spent Fuel Pool Filtration | Remove fine particulates and radioactive debris; maintain pool clarity and support safe fuel handling | |
| 7 | Radwaste | Remove suspended solids and separate oil from water in radioactive waste streams; support safe discharge and regulatory compliance | |
| 8 | Diesel Generator | Remove contaminants from lube and fuel oil; ensure reliable emergency power operation; reduce wear and extend engine life |
