On 6/16/2013, Fukushima Diary reported the multiple nuclide removing system possibly leaked contaminated water. (cf, Multiple nuclide removing system ALPS possibly leaks in the test operation [URL]) On 6/17/2013, Tepco announced the nuclide analysis data of the possibly leaking water from ALPS. The reading are below, All β : 6,700,000,000 Bq/m3 Cs-137 : 3,900,000 Bq/m3 [...]

[Column] Talk to myself in the future

“Hello, did I take you to the safe place ? Are you living well ? Are you still free ?” I sometimes talk to myself in the future. I don’t want to regret. I implement everything by counting backward from future that I want to see. You can say I’m working on computer all day [...]

[Analysis] J gov can take over Tepco for the decommissioning work of Fukushima with a major legal reform

More and more people are starting to question if Tepco can really handle the decommissioning work of Fukushima. About 10 days before this post, they lost power in Fukushima plant, which stopped the coolant system of the pools of reactor1, 3, and 4. Tepco concluded it was caused by “a small animal -rat“, but the [...]
