"The presidents gave instructions for a working group to be formed," Sergei Kiriyenko said. "A specific set of decisions on integration will be ready by May 15."
He said the group would consist of Russian representatives from Rosatom, and Kazakh representatives from the country's fuel and energy ministry.
Kiriyenko had previously said Russia intended to restore the nuclear power infrastructure that existed during the Soviet period, and was initiating talks with Ukraine and Kazakhstan on the subject.
"All nuclear power facilities on the territory of Russia, Ukraine and Kazakhstan are part of the single complex of the former Soviet Ministry of Medium Machine Building, which we need to restore," Sergei Kiriyenko said.
Most of the technological complex of the former Soviet Ministry of Medium Machine Building fell to Russian hands after the disintegration of the Soviet Union, but some of its elements are located in other Commonwealth of Independent States (CIS) countries, Kiriyenko said. Uranium is mined in Kazakhstan, while Ukraine produces turbines, he said.
