[2025 Chongqing Attraction] Travel Guide for The Scenic Spot 816 Underground Nuclear Project (Updated May)

The 816 Project Scenic Spot is located in Baitao Street, Fuling District, Chongqing City. It is a nuclear raw material production base independently designed and constructed by the People's Republic of China and deployed in a cave. It has the top-secret code name "816". The construction was approved by the Central Military Commission in 1966. Its full name is the "Third-line Construction Atomic Energy Reactor and Chemical Reprocessing Project." It is a typical representative of more than 1,100 projects in the "Third Line Construction" of New China. That year, more than 60,000 construction troops from across the country were mobilized to Baitao to start the 18-year project construction. The project has gone through three stages: emergency construction, delayed construction, and construction suspension. The total excavation area is 104,000 square meters. The tunnel consists of 18 large holes and more than 130 pilot tunnels, branch tunnels, tunnels and shafts. The main cavern is as high as 79 . 6 meters. By 1984, 85% of the construction work had been completed, and about 60% of the installation work had been completed. The total investment reached 746 million yuan (price in that year). Due to the complexity and arduousness of the engineering design and construction, it is known as the "Three Gorges in the Cave, the Underground Great Wall" and the "Heshi Bi buried deep in the mountains". It also has the characteristics of the "Three Gods" of magic, mystery and sacredness. 102 component storage pool The location where CCTV’s “Going to the Grassroots” special report “Remember” column covers an area of 1,326 square meters. Its main function is to accept components and non-working blocks removed from the reactor, as well as store and classify non-working blocks. The 102 factory building is divided into two parts: the operation room and the pool. Each pool is equipped with water gates (9 sets in total) for the pool to be filled and drained in turn. There are 400 bucket positions with poles in the entire pool for long-term storage of original parts and non-working blocks. After the components are stored for one year, they will be cleaned by special water. Send it down the corridor to Factory 818. Ring Road 8 Located in the post-processing area of the entire project. It is huge in size, majestic in surroundings, and the beautiful lights perfectly outline the majesty of the cave. You might as well come here to explore the mystery and magic of the original ecological cave. Reactor pot bottom Located on the third floor of the main reactor. There are many pipe corridors above the bottom of the pot, which is spectacular. The construction of the glass corridor allows visitors to have a better experience, walk quietly under the pot, and overlook the long nuclear light. central control room Located on the ninth floor of the reactor. The most advanced computer body in the country at that time was housed here, which was the "heart" of the entire military industry cave and the central hub for coordinating the entire nuclear fuel manufacturing process. The 104 Nuclear Power Plant is 31.2 meters high and 25 meters wide. The reactor is a dual-purpose reactor for production and power generation. It uses its nuclear waste heat to generate electricity in accordance with the principle of "focusing on nuclear production and supplementing power generation, producing first and then generating electricity".
