The USSR Once Tried Reversing a River's Direction with 'Peaceful Nuclear Explosions' (bbc.com) 46

"In the 1970s, the USSR used nuclear devices to try to send water from Siberia's rivers flowing south, instead of its natural route north..." remembers the BBC. [T]he Soviet Union simultaneously fired three nuclear devices buried 127m (417ft) underground. The yield of each device was 15 kilotonnes (about the same as the atomic bomb dropped on Hiroshima in 1945). The experiment, codenamed "Taiga", was part of a two-decade long Soviet programme of carrying out peaceful nuclear explosions (PNEs).

In this case, the blasts were supposed to help excavate a massive canal to connect the basin of the Pechora River with that of the Kama, a tributary of the Volga. Such a link would have allowed Soviet scientists to siphon off some of the water destined for the Pechora, and send it southward through the Volga. It would have diverted a significant flow of water destined for the Arctic Ocean to go instead to the hot, heavily populated regions of Central Asia and southern Russia. This was just one of a planned series of gargantuan "river reversals" that were designed to alter the direction of Russia's great Eurasian waterways...

Years later, Leonid Volkov, a scientist involved in preparing the Taiga explosions, recalled the moment of detonation. "The final countdown began: ...3, 2, 1, 0... then fountains of soil and water shot upward," he wrote. "It was an impressive sight." Despite Soviet efforts to minimise the fallout by using a low-fission explosive, which produce fewer atomic fragments, the blasts were detected as far away as the United States and Sweden, whose governments lodged formal complaints, accusing Moscow of violating the Limited Test Ban Treaty...

Ultimately, the nuclear explosions that created Nuclear Lake, one of the few physical traces left of river reversal, were deemed a failure because the crater was not big enough. Although similar PNE canal excavation tests were planned, they were never carried out. In 2024, the leader of a scientific expedition to the lake announced radiation levels were normal.

"Perhaps the final nail in the coffin was the Chernobyl nuclear disaster in 1986, which not only consumed a huge amount of money, but pushed environmental concerns up the political agenda," the article notes.

"Four months after the Number Four Reactor at the Chernobyl Nuclear Power Plant exploded, Soviet Premier Mikhail Gorbachev cancelled the river reversal project."

And a Russian blogger who travelled to Nuclear Lake in the summer of 2024 told the BBC that nearly 50 years later, there were some places where the radiation was still significantly elevated.

For better or worse, the Chinese are still carrying the torch of Soviet ideology, and the result is that they get a lot more done more quickly than anywhere else, because "resistance is futile" when a project gets the green light from on high. At the very least, we can look to China to see the cutting edge of what various experiments in grand-scale infrastructure projects can achieve, or fail to achieve. It's like a real-life simulation of pie-in-the-sky ideas that would never get past the political quagmires in the West.

        The fundamental issue is that explosions aren't a very efficient method of excavation. A lot of energy gets expended moving earth that didn't need moving, or that falls back in the hole. And it tends to produces circular(ish) holes which isn't ideal for making a channel. That might not matter so much if the power source is cheap, but it does mean you're using quite big bombs in proportion to the useful excavation you get. And bigger bombs mean more fallout. You'd do better putting the nuclear material in a reactor connected to a generator driving an electric excavator.

        The US did tests (Project Plowshare), but never actually tried to implement it.

      You can't really compare the two though. The Soviet effort was more of an experiment, where as China is using well established engineering principles, just on a scale that hasn't been seen anywhere else.

      It's not just China that is good at these kinds of infrastructure projects though, there are countries in Europe that get them done too. It's really down to politics screwing things up or not.

        This even applies to the United States in one specific area: roads and highways.

          Yes, and the absurd amount of time allotted is also almost always ignored. Any time I drive through a Caltrans project I think about how it would have been completed already in Japan.

        • I can explain the American Problem (outside of California). Many (most?) states have engineering performed by the lowest bidder. As you might guess, the plans and specifications are copy-paste garbage that will cause problems during construction. The RFIs (Requests for Information) are numerous and wouldn't be asked of a competent project. Other than design flaws, road building estimates are well organized (way better than building construction). Work items are detailed out and recent prices are known

        • I seem to recall in the USA, maybe it was back in the Clinton years where there were 3 to 5 year paybacks in infrastructure projects, it seems like there were plenty of them. It seems to create a lot of jobs and wealth. Instead of allocating funding based on which Senators get the most wasteful jobs in their states, like the SLS program, create a queue of infrastructure programs that have a quick payback, and pull the trigger on the ones that have the quickest payback. I would like to see a list of t
        • ...Highway projects are generally within time and budget

          Not.

          "The Government Accountability Office, for example, found that 77% of highway projects in the USA experienced cost escalation (in Kaliba et al., 2008). Merewitz (1973) suggests that the average overrun of infrastructure projects is a little over 50 percent (Merewitz, 1973)."

          https://arxiv.org/pdf/1307.217... [arxiv.org]

          Although compared to the massive cost overruns of some military procurements, I suppose 50% is in the noise.

    The US got into the planning stages of some pretty crazy nuclear bomb projects, I think mostly in the 60s. Hell, just recently Trump was talking about nuking hurricanes, an idea that did not originate with him, but with cold war era atom warriors.

    • The USA and USSR were both looking for peaceful applications of nuclear bombs in the 1960s which appeared to be taken quite seriously. The Soviets had at least one success in this:

        Yes, we even have ice cores showing that. There are multiple reasons Milankovitch cycles, solar insolation related to the age of a star, volcanic activity, and the energy retention characteristics of an atmosphere based on the composition of that atmosphere. Some retaining heat, like some carbon compounds (CO2, methane) and some that increase heat loss like Sulfuric Aerosols.

        One of the unfortunate things is that politicians can sometimes attempt to circumvent the laws of physics by voting on them. Or po

        True, but those naturally-occurring cycles are on a time scale of tens of thousands of years [nasa.gov] .

        The current warming is orders of magnitude faster.

      Awesome - thanks for the link. I've been searching out info now, and the Colorado river is seriously interesting. In addition to the flow reversal, there were apparently a lot of volcanic dams that would last a few decades, then collapse, with huge floods resulting.
