FILTRATION SYSTEMS
During refueling outages and periods of underwater work activity at nuclear power stations, it is necessary to filter the water to maintain water clarity. Also, it is good practice to vacuum up loose crud pockets or sludge which has accumulated around underwater equipment or in the general bottom areas of pools. To meet this need, Tri Nuclear Corp. initiated a program in to design, manufacture and market a new family of Underwater Filter/Vacuum units which are currently in use in virtually every plant in the U.S. and many overseas plants.
Tri Nuclear Underwater Filter / Vacuum units are ideally suited to perform the following:
– Water clarity for Reactor Vessel internal in service inspection projects. GE, Westinghouse / PCI, and Areva have all used Tri Nuclear UFV-260’s for ISI inspection work
– Underwater loose parts retrieval
– Reactor Cavity and Fuel pool surface skimming
– Fuel Cask Pit cleanup
– Underwater plasma cutting / EDM / mechanical cutting capture / filtration
– All Tri Nuclear Equipment is designed to help the plant exceed its ALARA (As Low As Reasonably Achievable) radiation goals
– Reactor Cavity and Spent Fuel Pool turbidity control
– Rapidly filter and cleanup pool water
– Reactor Vessel flange cleaning
– Reactor vessel internal and component underwater cleaning
– Reactor Water Storage Tank cleanup projects

Underwater Filtration Systems
UFV-100 System | 100 GPM Vacuum Filter System
Tri Nuclear has developed a compact stand alone underwater filter vacuum which is ideal for use on special projects or in confined areas where space is at a premium.
The UFV-100 is a compact unit on a 14” x 24” base. Ideal for use in confined areas. The system includes a housing, pump/motor assembly, hose, flow meter and special tooling. Design flow rate is 100 GPM.
UFV-260 System | 260 GPM Vacuum Filter System
Tri Nuclear has developed a versatile stand alone underwater filter vacuum which is ideal for use in the Spent Fuel Pool or Reactor Cavity and is the most widely used underwater filter vacuum on the market.
The UFV-260 is similar to UFV-100 with a 24” x 24” base and design flow rate of 260 GPM.
UF-600 System | 600 GPM Filtration System
Tri Nuclear has developed a large stand alone underwater filter which is ideal for processing large amounts of water rapidly for water clarity.
The UF-600 is manufactured with a 24” x 30” base and design flow rate of 600 GPM. This unit is designed for filtering operations and not vacuuming.
UFV-600 System | 600 GPM Vacuum Filter System
Tri Nuclear has developed a large stand alone underwater filter vacuum which can process large amounts of water rapidly for water clarity and still retains the ability for minor vacuuming campaigns.
The UFV-600 combines the features of the UFV-260 and the UF-600 in one unit by modifying a standard UF-600 by adding suction piping and filter tube covers.
UF-1000 System | 1000 GPM Filtration System
Tri Nuclear has developed our largest stand alone underwater filter vacuum which can process significant amounts of water quickly for water clarity. Rapid cavity water turnover minimizes the effect of poor water clarity on critical path time.
The UF-1000 is manufactured with a 34” x 34” base and design flow rate of 1000 GPM. This unit is designed for filtering operations and not vacuuming.
