In the early 1960s, China had one plant to make highly enriched uranium near Lanzhou and was completing one nuclear reactor to produce plutonium at Jiuquan. In 1964, China began the “Third Line” effort — a massive construction effort to relocate all of China’s heavy industries, nuclear and otherwise, in the interior of the country. Often these factories, including things as mundane as steel mills, were placed underground to protect them from Soviet or American attack. As you might expect, the disruption of attempting to relocate the country’s heavy industries to underground caverns in the rural interior was a complete and total cluster… well, you know. Wikipedia calls the Third Line “an economic fiasco,” which seems to me to be an example of the wisdom of crowds.

As part of the Third Line effort, China’s nuclear engineers were supposed to build a copy of the first reactor — the one where Cui worked — in an underground cavern being dug near Fuling. But placing a nuclear reactor under a mountain is about as slow and arduous as you might expect. At some point in 1969, with relations between Moscow and Beijing collapsing, Beijing decided it could not wait for the engineers to finish Fuling. The first proposal suggested physically picking up and moving the reactor near Jiuquan somewhere else. Eventually the technical personnel convinced the Chinese leadership this was total madness. So, instead, China started building a temporary replacement above ground, near a place called Guangyuan in Sichuan.

I always wondered how, in the middle of the paranoia associated with the Cultural Revolution, Chinese leaders came to their senses and ditched the underground reactor at Fuling in favor of the above-ground copy at Guangyuan. It turns out they didn’t. Instead of replacing one crazy project with a more sensible one, the Chinese doubled-down on crazy — continuing the reactor project at Fuling, starting a new one at Guangyuan and, we now know, starting the underground reactor at Yichang. … As best we can tell, China never finished the heavy water at Yichang, just as it never finished Fuling or any other number of wildly implausible Third Line projects. Construction at Yichang lumbered on through the 1970s, before being shut down around 1980 or so. At this point, the Chinese government took a number of steps to transition its nuclear industry to civilian power generation, converting and eventually decommissioning the reactor near Jiuquan, as well as giving up on Fuling and Yichang. China would not build a heavy water reactor until it bought CANDU heavy water reactors from Canada, one in 2002 and another in 2003. (CANDU is a portmanteau of “Canada” and “deuterium oxide,” better known as heavy water.) Yichang is just a footnote. A crazy, implausible footnote…….

Of the two plutonium production reactors that China finished, Jiuquan closed in the late 1980s and Guangyuan closed sometime in the 1990s. China never finished the reactors at Fuling or Yichang. China’s surprisingly small stockpile of plutonium isn’t so surprising once we know this historical context. They tried to make more. They just couldn’t…..

There will be more disclosures. Like yet another unfinished secret underground nuclear reactor that I haven’t mentioned. That’s right, there is a third underground nuclear reactor project that we’ve found. …..http://www.foreignpolicy.com/articles/2014/07/08/the_untold_story_of_chinas_forgotten_underground_nuclear_reactor_yichang_827_plant
