Westinghouse Electric Company has signed a contract with Ukrainian nuclear utility Energoatom to supply monitoring instrumentation systems for four units at the Zaporozhye NPP, the Westinghouse press service said. The project is part of the Complex Consolidated Safety Upgrade Programme of NPPs in Ukraine undertaken through loan agreements with the European Bank for Reconstruction and Development (EBRD) and Euratom.
Westinghouse will provide accident and post-accident monitoring systems and hydrogen concentration monitoring systems to power generation units 3, 4, 5 and 6 of the Zaporozhye NPP. The upgrade includes monitoring systems, along with severe and design basis accident field instrumentation, and additional miscellaneous equipment such as penetrations, cables, sensing lines, special tooling, accessories, spares, consumables, and special mounting and fixing provisions. Installation supervision, training and warranty for products and services are also included. Units 1 and 2 underwent extended upgrades in 2015 and 2016.
Westinghouse will carry out the project with selected Ukrainian companies including Kharkov-based Westron, which is an I&C joint venture between Westinghouse and Ukrainian control systems design company Hartron. The project will start immediately, Westinghouse said, with delivery to Zaporozhye 4 early next year, and the final delivery, to unit 6, at the end of 2019. Final acceptance of the last delivered system is planned for early 2021.
A programme to bring Ukraine's operating nuclear reactors into line with international standards and local regulations began in 2011. The EBRD in 2013 agreed a €300m ($327m) loan, along with a similar loan from Euratom. The overall cost of the project is estimated at €1.4bn. It was originally planned for completion this year, but the target date was moved to 2020 after Ukraine's 2014 change in government. Zaporozhye is Europe’s biggest NPP with six commercially operational VVER-1000 units each with a net capacity of 950MWe.
