Under the contracts, worth of $450m with a total potential value of approximately $500m, Curtiss-Wright will supply 16 plant reactor coolant pumps for the Generation III+ commercial nuclear power plants from 2019.

Curtiss-Wright chairman and CEO David Adams said: "We are extremely excited to announce the receipt of these new AP1000 contracts, which mark a major milestone in Curtiss-Wright’s history and build on our legacy as a critical provider of next-generation commercial nuclear power plant technology.

"Further, these agreements expand our long-standing relationship with our China partners, and reinforce our ongoing support for China’s growing nuclear power program."

The RCP are the canned motor pumps designed to circulate coolant water throughout the reactor and also represent one of the most critical components in the plant design.

Curtiss-Wright will manufacture the RCPs at its Electro-Mechanical Division (EMD) facility in Cheswick, Pennsylvania, US.

In 2007, Curtiss-Wright was awarded a contract to supply a total of sixteen RCPs for two AP1000 nuclear plants currently under construction in China. The plants include Sanmen Units 1 and 2 in Zhejiang Province and Haiyang Units 1 and 2 in Shandong Province.

The firm already delivered the first two pairs of AP1000 RCPs for Sanmen Unit 1 and expects to complete the delivery of RCPS during 2016.
