Reactor 3 Blows Up With Sound

http://everist.org/archives/Fukushima/20120430_Message_of_Fuku3.htm Fukushima Unit Three, Mar 30th, 2011. There is little damage to the girders above the reactor well, and the crane is also present below them. The frame damage in this area seems to be from the impact of rubble from the concrete roof slab, as it fell back down. Instead we see the girders are entirely destroyed and missing above the #3 Spent Fuel Pool. Mr Gunderson has pointed this out, suggesting there must have been a criticality in the SFP. I agree. Where I differ from Gunderson, is that I think there were three prompt criticalities in SFP #3, in rapid succession. There is just one video on the net of the Unit #3 explosion complete with sound. It was recorded live off-air from channel 9 TV in Australia by 'oztvwatcher', before anyone in the MSM networks thought to edit out the sound. It is hard to find the video as it seems to keep being taken down, but here is my saved copy. (679KB) Take and save that now while you can, in case I'm forced to remove it. It is one of the most significant videos you'll ever see. The crucial point in the video is, there are three very distinct and separate bangs, about equal in intensity, and half a second gap between each. One bang or three, what's the difference, it blew up, right? Perhaps it won't seem terribly significant when you first hear them. But once you understand what they signify, and the implications, they carry a terrible message. In this article I will tell you what it is.

  1. You asked about CLAB on another blog:

    CLAB is an intermediate storage of spent nuclear fuel. (Centralt Lager för Använt Bränsle, CLAB. My translation: Central Storage for Used Fuel)

    steveo77 wrote: "Neat, one huge spent fuel pool with 4500 tons going up to 8000 tons, all in one place. Wonder how that would turn out in a big quake and the water spilled out?"

    My attempt at answering:

    "When the fuel is taken out of the reactor, it is stored in water-filled pools at the nuclear power plant for at least nine months" "..."

    "There is so much water in the pools that it would take about a month before the fuel began to be exposed. This allows ample time to arrange backup cooling if needed. The rock caverns themselves are also a part of the safety system. They protect against intrusion and sabotage. The pools are specially designed to withstand earthquakes. Sliding bearings between the pools and the rock prevent the fuel and the pools from being damaged in the event of movements in the bedrock."

    Quote is from http://www.skb.se/upload/publications/pdf/ClabEng.8.3.pdf

    SKB is the company that is responsible for operation of CLAB. It is also responsible for developing and operating the future long term storage of spent nuclear fuel.

    Your point about earthquake safety has some merits. Dangerous quakes in Sweden are very rare, and it would be easy to overlook this problem.

    "An earthquake measuring 3.8 on the Richter scale shook homes in parts of Västerbotten in the north of Sweden late Tuesday evening. While no injuries were reported, the quake was considered to be strong on Swedish terms."

    The storage is 32 meters below ground (granite).

    So, in conclusion, I believe CLAB is quite safe from earthquakes.

    1. Indeed the Swedes are doing it better than the USA, the handling of spent fuel is a very important topic.
