Fukushima worker “If you have heatstroke in Fukushima plant, you’ll be fired”

  Working in the protective clothing is extremely hard and now it’s very hot. However, because of the shortage of nuclear workers, they can’t not even take enough rest not to have heatstroke.(cf. Fukushima worker “Shortage of nuclear worker is becoming serious”) On 7/31/2012, actual Fukushima worker commented the working condition in Fukushima. He says [...]

M5.6 hit Fukushima and radiation level spiked to be 42 μSv/h 4 hours later

At 14:51:51 of 6/28/2012, M5.6 hit Fukushima. Japanese seismic scale was 4. [LINK]       3 hours and 4 hours later, radiation level spiked up in Fukushima. The highest reading was 42 μSv/h.[LINK] Since 21:00, the graph has not been updated at the moment of 2:48 of 6/29/2012.     ↓ The video of [...]

12 tones of water leaked to the sea containing beta nuclides

12 tones of highly radioactive water leaked to the sea again. It leaked from the part after desalination unit, but because it can’t filter beta nuclides, Sr-90 and other nuclides have already leaked to the sea. However, the leaked water contained 16.7E+6Bq/m3 of cesium too. The flow from desalination unit to the tank increased by [...]

[Video] Inside of the SFP and container vessel of reactor 4

              Following up this article..SFP of reactor4 became cloudy Tepco checked the inside of the SFP and container vessel of reactor 4 on 3/15/2012. On 3/16/2012, Tepco released the video on their press conference. The degree of clearness was only 1m because of the white substance. The camera went [...]

Tepco is trying to put new heating gauge for reactor2

Actual Fukushima worker Happy11311 tweeted like this below   続き3:あと今日の作業で2号機の格納容器内に新しい温度計を入れる場所の調査が行われたでし。こちらも早く新しい温度計を入れないと今のままじゃ数値の正確性にかけるもんなぁ…。いずれにしても建屋内はどこに行っても線量高いから簡単に作業は進まないでし。 — ハッピー (@Happy11311) March 15, 2012   <Translate> Today we searched for the place to put new heating gauge into the container vessel of reactor2. Now we can’t tell the accurate temperature without new gauges. Anyway, it’s very highly radioactive wherever you go in the [...]

SFP of reactor4 became cloudy

Following up this article..Tepco released the video of the SFP of reactor 4 Tepco searched the inside of the reactor 4′s spent fuel pool with underwater camera again. They found out the degree of clearness was only 1m though it was 5m last time. Tepco explains impurity has gotten into the water on the assumption [...]

Temperature of reactor 6 picked up by 10℃

Following up this article..Temperature of reactor 6 is unstable The temperature of reactor 6 went up by 10℃ through only 6 hours. 3/10 6:00  27.6℃ 3/10 12:00  36.7℃ (↑ 9.1℃) There is no explanation from Tepco. The pressure of container vessel has also increased from 3/9. 3/9  12:00   0.020 MPa g 3/10   6:00   0.023 [...]

Temperature of reactor 6 is unstable

Reactor 6 is unstable. According to Tepco, the coolant system is working properly, they are not injecting water like reactor 1 or 2. However, the heating gauge showed 23.1 ℃ on 3/8 12:00 and it went up to be 27.5℃ on 3/9/2012 6:00. (↑ 4.4℃) ↓ 3/8/2012 12:00   ↓ 3/9/2012 6:00   Source 1 [...]

Cesium fall-out observed after the massive gas in the plant

Following up this article..Reactor buildings are hidden by thick smoke In the night of 3/1/2012, massive gas covered Fukushima plants. On the following 2 days of 3/2 and 3/3, cesium fall-out was observed in Tokyo. It was captured in Koto ku Tokyo, by germanium semiconductor detector.   15:00 3/1/2012 ~ 15:00 3/2/2012 Cesium 134 : 0.0002 [...]

Reactor crane was removed from reactor 4

  3/5/2012, Tepco removed the reactor crane of 110 tones to pick up nuclear fuel etc.. They will scrap the crane, shield highly contaminated parts. Tepco is planning to remove the cover of the container vessel in the end of August, start covering the whole reactor building. It’s planned to be the end of 2013 [...]
