No matter what we'll see, it will be creepy.<br /><br />At least reactor 1's pressure had been released early, unlike the others, so the vessel wasn't under pressure stress when the core got destroyed.<br />This because Reactor 1 is of an older type (BWR/3) and has different flaws.<br /><br />On pages 5+6 there is a description in this interesting document "Detailed analysis of the accident progression of Units 1 to 3 by using MAAP code", link: http://www.tepco.co.jp/nu/fukushima-np/images/handouts_120723_02-j.pdf<br /><br />Low-melting instrumentation tubes and gaskets that self-destruct in case of a meltdown, working like an automatic pressure relief to the containment.<br />Bug or feature?<br /><br /><br />By the way, the next video has been released: http://photo.tepco.co.jp/en/date/2012/201210-e/121011-01e.html<br /><br />In making the video, up to 51 workers have been irradiated: http://www.tepco.co.jp/en/nu/fukushima-np/images/handouts_121011_01-e.pdf<br /><br />Atomfritznoreply@blogger.comtag:blogger.com,1999:blog-1765307840677473617.post-42359091256492965732012-10-11T09:42:32.571-07:002012-10-11T09:42:32.571-07:00@ 12:10

In order to ascertain (or exclude) both hypotheses we do really need the "Toshit" stuff you mention.

What...Thanks for the video and its explanation. <br />What's the temperature there, I wonder. <br />== ElenaAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-1765307840677473617.post-35284565889235332072012-10-10T15:14:13.083-07:002012-10-10T15:14:13.083-07:00Really recommend to download the whole video.
High...Really recommend to download the whole video.<br />Highly interesting is the uncalm water surface in conjunction with the visible steam, together with the lack of "rain" like in #2.<br />So I believe the cooling water actually passes the RPV, before leaving part as water, part as steam.<br /><br />And, the regular distribution of radiation could mean that the corium (or far majority of it) didn't leave #1's RPV. If this is the case, this would probably be good news.<br /><br />So I look forward that "Toshit" (isn't this what you get when mixing "Toshiba" and "Hitachi"? ^^) will develop some telescope device so we can examine the the bottom part of the RPV to get some really useful information.Atomfritznoreply@blogger.com
