chernobyl water tanks

The art of designing a nuclear bomb involves three things: Getting the the bomb into a maximally super-critical state (implosion), starting the chain reaction precisely at the moment of maximum criticality (the polonium/gold neutron initiator), and then keeping the fissile material super-critical state for as long as possible to maximize the yield (the "tamper" material slows the expansion by tens of nanoseconds). The control system tank. If anyone has a real figure, I'd love to hear).

The explosion would have been between three and five megatons. I had heard this scenario many years ago and its primary source I believe was an interview with Gorbachev were he mentioned it (I cant find the source though, so take with a pint of salt). nationalboard.org/Index.aspx?pageID=164&ID=412, en.wikipedia.org/wiki/Father_of_All_Bombs. Of course it's not like an open reservoir would magically behave like a steam vessel when lava touches it, but it might be the source of this worst-case calculation. \end{align} Great question - I actually posted the exact same one, but you were first :) I had the same reaction to the show "Wait. Even if you've never taken an interest in studying world history, you've surely heard the name Chernobyl. By pavelcherepan, June 12, 2019 in Physics. A final factor that I did not consider is chemical reactions: if the interaction of corium, water, and fresh air (brought in by an initial physical steam explosion) could trigger spontaneous chemical reactions, then the energy available could be significantly higher. GILMORE October.29.2014 at 11:50 am The turbine hall. In reality, while there were fears of a second explosion, the scale of the potential disaster was unclear at the time. I too considered it to be without much foundation (Given the known facts its out right impossible unless they had stored nuclear weapons hidden under the cores foundation) and given that it comes out of a man that isn't a scientist but a politician, my best guess would be that the 3 megaton figure should not be considered as the yield of an explosion event but more likely the fallout equivalent of the radiation that would have been released after the steam explosion and the subsequent destruction of the remaining 3 cores at the vicinity. It took our top scientists and engineers multiple years to achieve kiloton-scale bombs, and years more to achieve megaton-scale bombs using fusion. \begin{align} And below the reactor were water tanks which contained 7,000 cubic meters of water (according … This is several orders of magnitude lower than the "megatons" estimate provided in your question, but does agree with your gut response that "megatons" seems unreasonably high. “Immediately I heard a noise that meant the water was draining. rev 2021.4.26.39152. Why is the mid-deck on the Space Shuttle named as it is? It is also important to remember that, even if accounting for these factors increased the upper bound by a few orders of magnitude, this calculation still gives only an upper bound on the explosive work; the real energy extracted in a steam explosion would likely be much lower. Evidence of debris launched in the event indicates a fresh nuclear explosion. Recall that for nearly 30 hours after the accident, the operators on scene were insisting that it had not happened, that it couldn't happen, and that it was "no big deal".
