A teaming agreement signed by Westinghouse Electric Company and SPX brand ClydeUnion Pumps outlines a joint marketing plan for the ClydeUnion Pumps Turbine Water Lubricated (CUP-TWL) pump that features new plant applications and operating nuclear power plants worldwide.

CUP-TWL pumps are used in Pressurized Water Reactors (PWR) as the Turbine-Driven Auxiliary Feed Water (TDAFW) pump and in Boiling Water Reactors (BWR) as the Reactor Core Isolation Cooling (RCIC) pump. ClydeUnion Pumps technology offers several advantages, including: operating without AC or DC power, pumping hot process fluids (>100oC), use of nonflammable lubrication, excellent transitory response, and small footprint with fewer parts.

“This teaming agreement provides Westinghouse global nuclear BWR and PWR customers with more options for products and services that will enhance safety across the global fleet,” says Doug Holderbaum, director of Westinghouse Post-Fukushima Safety Products and Services. “The CUP-TWL extended coping package is part of Westinghouse’s larger effort to provide its global customers with products and services that enhance safety while addressing lessons learned from Fukushima.”

The feature that makes it possible for a plant to operate without supporting AC or DC power, disassembling equipment or making emergency modification is especially important for plants that require extended coping duration for loss of AC power. Westinghouse is able to provide a complete package of permanent hardware and system modifications to allow local, manual operation.

The CUP-TWL pump has undergone full nuclear quality assurance due to its designation as a safety-related pump for both PWRs and BWRs and its original development maritime applications. The pump has also been accredited by several organizations, including the American Society of Mechanical Engineers.

More than 400 pump units are currently in use around the world for both nuclear and non-nuclear services. This includes PWR’s in the U.K., Sweden, Republic of Korea and China, and BWRs in Taiwan.

Westinghouse offers a variety of other products and services that address Fukushima lessons learned, such as SHIELD® passive thermal shutdown seal; FLEX assessment, planning and implementation; guided wave radar spent fuel pool level instrumentation; seismic and flooding hazards evaluation, including seismic probabilistic risk assessment (PRA); hydrogen control solutions; containment filtered vent solutions; and plant-specific implementation aspects.
