Under the contract, Westinghouse Electric will deliver fuel for their reactors, annually, during the five-year period of 2016 to 2020.
Westinghouse will produce the fuel at its facility in Västerås, Sweden and has been the main fuel supplier to OKG, having delivered nearly 8,500 fuel assemblies to the plants.
Westinghouse Northern Europe vice president and managing director Johan Hallén said: "It also helps us strengthen our position as a leading boiling water reactor fuel supplier on the European market which ensures a strong domestic industry employing thousands in Sweden."
The three boiling water reactors (BWR) were developed by ASEA-ATOM and were acquired by Westinghouse in 2000.
