Westinghouse in the US, one of the largest companies in nuclear business and subsidiary of Toshiba, is set to receive orders for the nuclear power plant project in Czech Republic. Prime Minister Shinzo Abe and Czech President Miloš Zeman will exchange a memorandum of understanding of mutual assistance in nuclear technology during the summit meeting on June 16. The total project cost is projected to be 10 billion dollars (about 1 trillion yen). Japan's nuclear export, which was interrupted by the March 11, 2011 disaster, is set to accelerate.
