Graver Technologies engineers effective ion exchange and filtration technologies for fuel pool management.
Nuclear fuel pools are essential water-filled storage systems designed to safely contain spent nuclear fuel assemblies after their removal from reactor cores. These nuclear cooling pools serve the critical function of providing both radiation shielding and heat removal from highly radioactive spent fuel elements that continue to generate significant thermal energy and radiation for years after reactor operation. At Graver Technologies, we offer reliable and durable nuclear fuel pool filters that ensure optimal water quality and safety standards in these demanding environments. These nuclear cooling pool solutions provide superior deionization, particulate removal, and radionuclide control while maintaining excellent water clarity essential for fuel handling operations and long-term storage integrity in nuclear power facilities.
Graver Technologies provides comprehensive nuclear spent fuel pool filtration systems engineered specifically for the demanding requirements of nuclear facilities. Our extensive product portfolio addresses diverse operational needs through specialized filtration technologies.
Our nuclear fuel pool water treatment solution incorporate advanced engineering principles to deliver superior performance in the most demanding nuclear environments.
At approximately 12, 18, or 24 month intervals each nuclear plant schedules a refueling outage to replace a portion of the nuclear fuel. The spent or used fuel still generates heat and radiation and must be handled and stored safely. The fuel assemblies that have been removed from the reactor are stored under water in the Spent Fuel Pool. Good water quality is important to prevent degradation and help maintain the integrity of the spent fuel assemblies. Spent Fuel Pool ion exchange systems—either Powdex® pre-coat systems or deep beds—are used in many plants. Graver provided the original Powdex resins for the pre-coat systems and today most use one of the Ecodex® mixed bed precoat products to simultaneously deionize and filter particulates, maintaining good clarity in the pool. Gravex® bead resins are particularly useful in the deep bed systems. Typical mixed beds were used for many years and are still useful today. The Spent Fuel Pool environment can affect resin degradation so we recommend a specialty Gravex mixed bed containing a high capacity, more stable cation.
How do Graver’s spent fuel storage pool filtration systems work?
Graver spent fuel storage pool filtration by utilizing high-capacity nuclear grade resins, ion-exchange resins, and stainless steel septa to remove contaminants and maintain water clarity in spent fuel pools.
How often should spent fuel pool filters be replaced or maintained?
Spent fuel pool filters should be maintained and replaced periodically based on operational conditions, pool water quality, and the manufacturer’s recommendations to ensure optimal performance.
What is the difference between fuel pool filtration and reactor water cleanup?
Fuel pool filtration focuses on cleaning and purifying water in spent fuel pools, while reactor water cleanup targets the cleaning of water in the reactor circuit, which involves different systems and requirements.
Can Graver fuel pool filters handle high-radiation environments?
Yes, Graver fuel pool filters are specifically designed to function effectively in high-radiation environments, ensuring durability and long-term performance in nuclear settings.
Are these filters compatible with existing nuclear plant filtration systems?
Yes, Graver’s fuel pool filters are compatible with most existing nuclear plant filtration systems and can be integrated seamlessly into current operations.
Do Fuel Pool Filtration systems meet nuclear safety and regulatory standards?
Yes, Graver Technologies’ fuel pool filtration systems comply with nuclear safety standards and regulatory requirements to ensure safe and effective filtration in nuclear power plants.
