Uranium miner Energy Resources of Australia (ERA), which posted net losses by more than 50 per cent in the first half to $59.86 million, remained confident consumer interest in uranium will be renewed, what with Japan already starting to re-embrace it and demand from China continues to grow.

The 2011 Fukushima nuclear disaster may have spooked the nations into the efficiency and safeness of nuclear power, nevertheless, countries will still consider it as a viable alternative power source.

''Despite some slower growth in the medium term as China transitions to an increased reliance on improved nuclear power generation technology, ERA expects that the country will be one of the largest uranium consumers within the decade,'' the company said.

China is expected to become one of the largest uranium consumers within the decade, as it constructed 26 nuclear reactors.

As for Japan, "I would say there will be a slow restart of nuclear reactors," Rob Atkinson, ERA chief executive, told AAP. However, he believed this will only be temporary.

"Pragmatically speaking, finding new power sources takes many years, it takes a great deal of cost," he said. But "nuclear will continue to play a part in the Japanese power strategy."

ERA, which oversees the world's second biggest uranium mine, on Thursday reported a net loss of $59.9 million in the first half of the 2012 financial year due to a drop in the sales of uranium oxide, a robust Australian dollar and heavy rain season. Its uranium revenue dropped to $148 million, from $235.6 million in the June half.

ERA is a listed subsidiary of Rio Tinto and controlled at 68 per cent.
