Nuclear Power Solutions

Nuclear Power Plants Typically Need To:

  • Minimize radioactive exposure
  • Meet today’s stringent regulatory requirements
  • Reduce total cost of ownership

Pall can provide a complete analysis of the systems in your plant and recommend the optimal filtration and separation products and technologies to improve efficiency. You will receive real-world, long-term solutions.  With today’s sophisticated nuclear plants, a high level of technical proficiency is required to properly inspect, diagnose, and make recommendations for your systems;  with more than 50 years of experience in providing innovative filtration and separation technology, Pall has the expertise you can rely on.

Make-up Water

The quality of your make-up water is critical to the operation and maintenance of your steam generator and condensate systems.  Pall Aria™ treatment systems consistently provide high-quality effluent, regardless of the water source.  

Drinking Water

At power plants throughout the world, Pall Aria microfiltration systems have been preferred for drinking water treatment.  Through the safe and cost-effective reduction of disease-causing organisms, Pall Aria systems can provide your plant with drinking water that meets strict quality standards.


Successfully removing the undesirable constituents from wastewater streams is critical for conformance with stringent environmental regulations.  Pall offers advanced wastewater management systems that are fully integrated, reliable, flexible, and easy to use.  They are designed to optimize each step in the wastewater treatment process.  Our Pall Aria microfiltration and ultrafiltration systems, backwash systems, and reverse-osmosis systems successfully treat wastewater to meet your requirements, even when they are zero liquid discharge.

Steam Turbine Management

Pall provides products and services to improve the reliability, output, and efficiency of your steam turbine.  Our total approach to turbine fluid systems optimizes turbine operation and reduces costs.  We help ensure that all turbine fluids meet the most recent INPO requirements for steam turbine management.

For the smooth operation of your steam turbine, we recommend the Ultipor® III filter and the Ultipor Dirt Fuse filter -- the most commonly used filters in steam turbine systems.

EHC Fluid Treatment

The Pall HRP purifier enhances the operation of your EHC system.  It combines anionic and cationic ion exchange with mass transfer dehydration and the particulate filtration to control acid formation and maintain high-volume resistivity.  The HRP also reclaims degraded phosphate ester systems by removing metal salt deposits.

Turbine Lube Oil

Your lube oil contamination problems can be resolved by implementing one of Pall’s turnkey turbine lube oil systems.  Our systems use high-efficiency filtration, coalescence, and mass transfer dehydration to combat contamination from water and solids. Your benefit: consistently clean, dry oil

Hydrogen Seal Oil

Particulate and moisture in your hydrogen seal oil system can cause serious generator problems.  Our hydrogen seal oil systems prevent these problems by protecting the seals from abrasive wear and preventing water from ingressing into the generator.  Pall offers systems proven to maintain seal integrity, protect hydrogen purity, and minimize maintenance of the sealing system.

NSSS/CVCS Submicronic Filtration

Submicron absolute-rated filters can reduce radioactive exposure from your Nuclear Steam Supply System.

Exposure of plant personnel to radiation is a serious concern. Absolute-rated Pall Ultipor® GF Plus filters effectively remove sources of radioactive exposure.  They also reduce overall dose rates during refueling outages.

CVCS filter elements are expected to provide maximum removal of irradiated particulate and eliminate erosive wear of reactor coolant pump (RCP) seal surfaces.  Filter elements with submicron ratings are needed to prevent seal surface corrosion.  With a submicron removal rating of 0.1μ, the Ultipor GF Plus filter can significantly reduce resin fragments and corrosion products while protecting your deep-bed demineralizer.  This filter has also been demonstrated to reduce out-of-core radiation levels and prevent fouling of heat transfer equipment.

Our graduated filter replacement program (GFRP) is designed to maximize your cost savings by using coarser filters first, then gradually progressing through a series of continually finer filters as the inventory of particulate in your system is reduced and then maintained at the desired level.


Seal Water Injection (SWI)

Seal water injection filters also prevent erosive wear of reactor coolant pump (RCP) seal surfaces.  Ultipor® GF Plus SWI filters and Seal Water Return (SWR) filters are industry-proven to maintain seal leak-off rates by removing submicron particles.  The removal of metal oxides and other particulate matter from your seal water ensures adequate cooling of the pump shaft and seal surface protection, thereby reducing the frequency of costly RCP seal replacement.

Fuel Pool

An optically clear and radiologically clean fuel pool can minimize delays resulting from crud bursts during refueling.  Personnel exposure can also be decreased.  Saving time and reducing radioactive exposure can cut your operating costs by millions of dollars.

Pall recommends Ultipor® GF Plus filters to optimize the visual clarity of your fuel pool.  These filters are used in the cleanest nuclear plants in the world to protect against radiation and to reduce waste volumes.  They are strongly bonded, migration-free, and capable of removing particles far smaller than the rated pore size.  Our 140 series filter has the same attributes and is constructed of the same medium as the Ultipor GF Plus filter.


Pall filters are effective for the clarification of liquid radwaste having both high and low solids loading.  Radwaste filtration, like fuel pool clarification, can be accomplished using backwashable or disposable systems.  Pall radwaste filtration systems provide highly effective decontamination of liquid radwaste.  We offer complete backwashable systems that provide continuous, automated, long-term service for small- and large-flow applications.  Our disposable systems are equipped with filter elements that are highly permeable and especially sturdy and efficient.

Reactor Water Cleanup (RWCU)

Replacing septa with Pall porous metal membranes prevents resin leakage and improves reactor water quality.  Spiral-welded mesh, wedge wire, and coarse metal elements commonly found in RWCU systems allow significant resin leakage.  Pall offers PMM® and Rigimesh® metal media as alternatives.  These filters prevent leakage without compromising filter efficiency and without the addition of cellulose fiber.  In the absence of fiber, ion exchange capacity is improved and waste costs are reduced.  Converting to PMM membranes or Rigimesh membranes can substantially reduce the total time to precoat and to bring your system to full flow.

Traps and Laterals

Our traps and laterals are constructed of extremely durable media to prolong the life of your demineralizer system.  Resin laterals and traps constructed of Pall’s Rigimesh medium can lower differential pressure, improve resin fragment retention, and increase the service life of your demineralizer.  This medium is an extremely strong, highly permeable, sintered stainless steel woven wire mesh available in a range of micron-removal ratings.  It forms a rigid barrier that withstands high pressure and temperature and is known for its exceptional dirt-holding capacity.
