According to Interfax-Ukraine, the agreement was signed in Washington on March 31 as part of the working visit of Ukrainian President Petro Poroshenko to the US. "In particular, the agreement concerns the issue of uranium supplies from Australia to Ukraine for nuclear energy," the energy ministry earlier said. Demchyshyn in October last year reported that Ukraine is in talks with Kazakhstan and Australia for purchase of uranium concentrate to diversify its supplies. The annual needs of Ukrainian nuclear power plants for uranium concentrate are about 2,400 tonnes, while its internal production by state enterprise VostGOK in 2015 is planned in the amount of 1,200 tonnes. The needed nuclear fuel was earlier imported from Russia.
