Westinghouse Electric has secured a contract from Teollisuuden Voima (TVO) to supply new traversing incore probe (TIP) systems for two boiling water reactors (BWR) at Olkiluoto, Finland.

These systems are installed to calibrate the nuclear reactor power measurement.

Pursuant to the contract terms, Westinghouse subsidiary Westinghouse Electric Sweden will handle the overall project and perform the mechanical/electrical installation and commissioning. Westinghouse Electric and Toshiba Corporation will jointly implement the project.

Most of the equipment will be manufactured and assembled in Japan and a factory acceptance test is likely to be conducted in December 2015.

Delivery of the equipment is scheduled for January 2016, while the installation is scheduled during planned outages at Unit 1 in 2016 and Unit 2 in 2017.

In addition to this, the project also requires the manufacture and installation of 28 new guide tubes and the provision of electrical installation and instrument and control (I&C) cubicles for control and measuring.

"These systems are installed to calibrate the nuclear reactor power measurement."

The TIP systems calibrate incore neutron flux detectors in the Olkiluoto 1 and 2 nuclear reactors.

Together with data from incore neutron flux detectors, the TIP data is used by the process computer to analyse the power distribution within the reactor core and determine whether thermal limits are being satisfied, Westinghouse Electric said.

Westinghouse Electric vice-president and managing director for Northern Europe Johan Hallén said that the agreement reflects TVO's assurance in the quality and reliability that Westinghouse and Toshiba together can bring to TVO.
