BRASILIA, October 31 (RIA Novosti) - Russia has offered Brazil modern methods for the production of uranium, new nuclear power plants and superconducting technologies, the CEO of the Rosatom state nuclear corporation said Friday.

"The first direction of cooperation is the prospecting and production of natural uranium," said Sergei Kiriyenko, who is in Brazil to lead the Russia Days events.

Kiriyenko said 25-30% of Brazil's territory had been surveyed at shallow depths for uranium deposits, and even such a limited search showed reserves of 350,000 tons, putting Brazil sixth globally.

"We have a firm conviction that if modern technologies were used here [and Russia has deep prospecting technologies], then natural uranium reserves in Brazil could be increased by many times, at least threefold but possibly five- or tenfold," he said.

Kiriyenko also said the two countries could cooperate in the nuclear sphere.

Touching upon the power transmission problem, he said Brazil has "a very big interest in low-temperature conductors," while Russia is a world leader in superconducting technologies and is ready to share its experience.

Kiriyenko said Russian-Brazilian trade would soon exceed $10 billion annually.
