Westinghouse Electric Company said Tuesday it had signed a contract with Teollisuuden Voima Oy (TVO) in Finland to deliver new feedwater spargers to the Olkiluoto Nuclear Power Plant Units 1 and 2.
The scope of the contract starts with engineering, designing and analyzing eight feedwater spargers – feedwater distributors. It also includes manufacturing and installing the spargers at the plant.
These spargers will be designed to distribute water from feedwater lines through the reactor pressure vessel. The company said it would “apply the latest techniques to improve the spargers' ability to withstand “thermal fatigue.” This will improve their operational life and reduce thermal pressure on surrounding structures, Westinghouse said.
The design and analyzing work will be done by Westinghouse at the company's offices in Vasteras, Sweden. The manufacturing will be done at a local supplier in Finland. The due date for delivery is the spring of 2017. The plan is for a Westinghouse team to install the first four spargers during the planned May 2017 servicing outage, the company said.
