The American Westinghouse Electric Co. is on the brink of inking a deal with Ukraine that would not only extend its contract to supply the country’s nuclear reactors with fuel, but increase the number of reactors to which it supplies fuel as well as the frequency of fuel deliveries here through 2020, according to a company official involved in negotiations.

Michael Kirst, Westinghouse vice president of customer relations and sales in the region, told the Kyiv Post on April 4 that the deal between the company and Ukrainian energy operator Energoatom is in its final stages.
