WASHINGTON, March 17, 2017 (Yonhap) -- North Korea is believed to have built and is operating a plant to produce lithium 6, a key ingredient for hydrogen bombs that are much more powerful than conventional nuclear weapons, a U.S. think tank claimed Friday.

The Institute for Science and International Security (ISIS) said the plant appears be located at the Hungnam Chemical Complex near Hamhung on the North's east coast. It cited a 2012 order the North placed in China to purchase large quantities of mercury and lithium hydroxide, key materials to produce lithium 6.

"Lithium 6 is a critical raw material needed for the production of single-stage thermonuclear and boosted fission weapons. These findings add credibility to North Korea’s claims that it has been developing thermonuclear or boosted fission weapons, regardless of the actual status of those efforts," ISIS said in a report.   http://english.yonhapnews.co.kr/news/2017/03/18/0200000000AEN20170318000200315.html?did=2106m
