The China Jinping Underground Laboratory (CJPL), the world's deepest and largest of its kind, started early scientific research on Dec 7, with 10 scientific groups beginning work. It is jointly built by Yalong River Hydropower Development Co., Ltd., a subsidiary of State Development & Investment Corp., Ltd., and Tsinghua University.
Located 2,400 meters beneath the surface in the Jinping Mountain Tunnel of the Jinping Hydropower Station in Liangshang Yi Autonomous Prefecture of Southwest China's Sichuan Province, the CJPL is a key scientific infrastructure of the country's 13th Five-Year Plan (2016-20) and has also been listed in its 14th Five-Year Plan (2021-25).
Construction of the project started in December 2020.
It is the first ultra-deep underground laboratory infrastructure in China and the world's largest integral experimental facility with an ultra-low radiation background.
