GE Hitachi Pumps Improve Nuclear Plant Safety

by | Sep 1, 2015

General Electric Hitachi Nuclear Energy is working with utility customers in Japan to deliver turbine water lubricated (TWL) pumps manufactured by ClydeUnion Pumps, an SPX brand. The steam-powered pumps are designed to ensure emergency reactor cooling in the event of a complete station blackout and can function when fully submerged in water.

GEH has shipped two units to Tepco’s Kashiwazaki-Kariwa Nuclear Power Plant. Two additional units are scheduled to ship to the plant later this year. GEH has additional commitments to support systems for Chugoku Electric Power Company’s two Shimane plants, and Tohoku Electric Power Company’s Onagawa and Higashidori plants.

GEH and ClydeUnion Pumps have a teaming agreement to offer the TWL pumps, which feature a unique and compact design, simplified turbine controls, reduced maintenance requirements and the ability to operate with no external electrical power.

As part of this high-pressure alternate coolant reactor safety enhancement solution, GEH offers specifications for design, material, fabrication and quality and project management services.

In July, Michigan-based DTE Energy awarded outage services work to GEH and GE Power Generation Services for the utility’s Fermi 2 Nuclear Power Plant. GEH will provide a host of outage and inspection services related to the boiling water nuclear reactor at the Fermi 2 plant in Newport, Michigan, while PGS will provide inspection and maintenance services to the main generator and six turbine valves. The services will be provided during an outage this fall.
