Curtiss-Wright and NuScale Power sign contract for the design of control rod drive mechanisms

PARSIPPANY, N.J., Nov. 12, 2012 (GLOBE NEWSWIRE) — Curtiss-Wright Corporation (NYSE:CW) announced today that its Flow Control segment’s Electro-Mechanical Division (EMD) business unit has signed a contract with NuScale Power to design control rod drive mechanisms (CRDMs) for NuScale’s small modular reactor (SMR). Curtiss-Wright will design the CRDMs, which control the insertion and removal of control rod assemblies, at its facility in Mt. Pleasant, Pa. The initial contract covers the design phase of the program.  

“This is a significant contract in many ways,” said Martin R. Benante, Chairman and CEO, Curtiss-Wright Corporation. “First, we are proud to begin a productive partnership with NuScale. Second, small modular reactor CRDMs are a key driver of growth for Curtiss-Wright and we are pleased to be working on the development of this important technology. Third, it continues our long-standing commitment to the future growth of the worldwide nuclear power market and the creation of clean, affordable energy and thousands of high quality jobs.”

Curtiss-Wright is a world-class designer and manufacturer of CRDMs, having supplied over 5,000 units worldwide for nuclear power plants, including the first-ever installation on a reactor head in the U.S. The Company brings its vast experience supporting existing operating reactors globally and new build reactor designs, particularly for the Westinghouse AP1000, to the application of this technology for small modular nuclear reactors.  

“With Curtiss-Wright’s leadership in the design of CRDMs for use in NuScale’s SMR power modules, our customers are assured of high performance technology,” said Paul Lorenzini, Chief Executive Officer, NuScale Power LLC. “We are pleased to add Curtiss-Wright to our team of world-class suppliers.”

NuScale is pursuing U.S. Nuclear Regulatory Commission (NRC) approval for its SMR design, which is an integral pressurized-water reactor (iPWR). The design is a natural circulation light water reactor with the reactor core and helical coil steam generator located in a common reactor vessel in a cylindrical steel containment. The reactor vessel/containment module is submerged in water in the reactor building safety related pool. The reactor building, which is located below grade, is designed to hold 12 SMRs. Each NuScale SMR has a rated thermal output of 160 MWt and electrical output of 45 MWe, yielding a total capacity of 540 MWe for 12 SMRs.
