China National Nuclear Corp. (CNNC), the country's largest atomic energy developer, said on July 17 that it has achieved a record drilling depth of 2,818.88 meters in uranium mining.

CNNC announced the technological breakthrough in uranium-rich Fuzhou, capital of southeast China's Fujian Province.

China's uranium prospecting has typically been carried out at depths less than 500 meters. Its previous record drilling depth reached 1,200 meters.

CNNC said the new drilling technology can help boost China's domestic uranium supplies and ensure the key energy source for developing nuclear power.

In addition to the drilling depth, the company said it has independently developed drilling equipment and hyperspectral identification technology that would facilitate uranium exploration.
