Westinghouse and Technofast reach agreement to provide hydraulic nut technology

PITTSBURGH, April 23, 2003 – Westinghouse Electric Company and Technofast Industries have reached an agreement under which Westinghouse will provide TechnoFast Hydraulic Nut technology to commercial nuclear plant customers.

TechnoFast’s all-metal hydraulic seal design allows the nut to withstand, without degradation, the high temperatures and high radiation environments common to reactor coolant pump main flanges, reactor vessel head closures, and other nuclear steam supply system components.

The hydraulic nuts thus have a usable life expected to equal or exceed that of the plant. Additionally, using hydraulic technology can greatly reduce radiation exposure times for plant personnel, eliminate time consuming measurement and trimming adjustments, and provide immense time and cost benefits in quickly getting the plant back online.

TechnoFast Industries is located in Australia and has been designing and manufacturing specialized hydraulic fastening devices and performing associated engineering services since 1992. The principal activity of TechnoFast Industries is the unique design and manufacture of high-pressure, hydraulically operated nuts and bolt-tensioning devices that can be quickly and easily fitted and used on critical applications (with standard hydraulic pumps and equipment).

Westinghouse Electric Company, wholly owned by BNFL plc of the United Kingdom, is a nuclear power company and is a supplier of nuclear plant products and technologies to utilities throughout the world. Today, Westinghouse technology is the basis for approximately one-half of the world’s operating nuclear plants.
