Emerson Process Management has won contracts totaling $17m from Westinghouse Electric Company to supply its Ovation expert control technology at four new Westinghouse AP1000 nuclear reactors in China.

Emerson’s Ovation system will be installed at the Sanmen nuclear power plant in Zhejiang Province and at the Haiyang nuclear power plant in Shandong Province.

Each plant has two 1,000MW reactors currently under construction, with more units planned.

The first Sanmen unit is slated to come online in 2013 while the first Haiyang unit is expected to begin commercial operation one year later.

For these units, Ovation technology will control power generation processes, provide an interface to operations and maintenance systems, and collect and distribute plant-wide information for process and power generation management.

Emerson will supply a total of 380 cabinets and controllers, 220 workstations and 2,245 I/O modules.

Under separate contracts awarded previously, Emerson is also providing Fisher control valves, TopWorx position sensors, and Bettis valve actuators for the Sanmen and Haiyang units.
