Construction of radioactive waste disposal lab underway

China is building a massive underground laboratory to research disposal technologies for high-level radioactive waste, the most dangerous byproduct of nuclear technology and applications. This is meant to pave the way for a repository that can handle the disposal of at least a century's worth of such materials for tens of thousands of years, the lab's chief designer told China Daily in an exclusive interview.

The lab will be situated in granite up to 560 meters below ground in the Beishan region of Gansu province, said Wang Ju, vice-president of the Beijing Research Institute of Uranium Geology. The underground lab was listed as one of China's major scientific construction projects in the 13th Five-Year Plan (2016-20).

Its surface facilities will cover 247 hectares, with 2.39 hectares of gross floor space. The underground complex will have a total structural volume of 514,200 square cubic meters, along with 13.4 kilometers of tunnels, he added.
