Here's a nice Toshiba PR video showing the Unit 2 device being tested prior to deployment. It shows the design and operation clearly. There's also a good illustration. https://www.toshiba-energy.com/en/info/info2019_0128.htm

Thanks, Sotan. Here is TEPCO's report, with photos and diagrams. Odd there's no photo of the probe itself. https://www7.tepco.co.jp/wp-content/uploads/handouts_190213_01_e-1.pdf

Tepco, NDF (Nuclear Damage Compensation and Decommissioning Facilitation Corporation), and the IRID consortium which is developing a lot of the new technologies for this decommissioning, seem to believe that it will be possible to remove the melted fuel material. Last summer it was announced...

The English-language version of Tepco's recent Unit 2 investigation report that Sotan linked to is now available: http://www.tepco.co.jp/en/nu/fukushima-np/handouts/2018/images/handouts_180119_01-e.pdf Photos and videos here: http://photo.tepco.co.jp/en/date/2018-e/201801-e/180119-01e.html The...

I'm not sure if this has been posted here yet, but it's very informative regarding TEPCO estimates of fuel melt and disposition, including muon scan results. Unit 3 muon scans weren't available yet, I think: Estimation of current status inside RPV and PCV at Fukushima Daiichi NPS July 3, 2017...

Here's the English version of the press release about the samples: http://www.tepco.co.jp/en/nu/fukushima-np/handouts/2017/images/handouts_170921_01-e.pdf

<I wonder why it took so long.> Yes, it's a bit baffling. Also, there's no indication of where the samples are being sent for analysis.

Once again, English version of the brief report has been posted here: http://www.tepco.co.jp/en/nu/fukushima-np/handouts/2017/images/handouts_170721_01-e.pdf

Here's the English-language short report of the July 19th Unit 3 submersible survey: http://www.tepco.co.jp/en/nu/fukushima-np/handouts/2017/images/handouts_170719_01-e.pdf

Hi all. I mentioned some time ago that I was working on an update to the Safecast Report. I finished it a couple of weeks ago, actually, and it's available for download here: http://blog.safecast.org/the-safecast-report/ Section 2.1 deals with issues at Daiichi. I cited some of Sotan's...

Here's a news report from the evening of March 12, 2011, which says (my translation again): "TEPCO admitted the possibility of core melt (roshin yōyū) as pointed out by NISA." Asahi Shimbun March 12, 2011 20:26 http://www.asahi.com/special/10005/TKY201103120510.html How and why this got...

Sotan, Thanks! The Nikkei Journalist is Junichi Taki. I have a pretty positive impression of him from earlier articles as well. Now, as you may be aware, people are posting links to early press comments where govt and TEPCO spokespersons did in fact say that "there is a possibility of...

Here's another article about the "meltdown" declaration manual, in the Nikkei Shimbun, a pretty conservative paper: http://asia.nikkei.com/Business/Companies/Meltdown-the-crisis-that-dared-not-speak-its-name

It's been a long time since I've posted, so hello to everyone. Some of you may remember I'm very involved with Safecast. I'm working on an update to the Safecast Report which includes a section about the situation at the Daiichi site. I figured I'd check to see what was being discussed here, and...

Rive, I definitely agree that monitoring of contamination in fish caught of Japan needs to be continued for the long term and improved. Maybe the least predictable aspect is what could happen in shallow water off coastlines like Hawaii, Aleutians, or the West Coast. Maybe nothing above the...
