NISA = Japan’s Nuclear and Industrial Safety Agency - thru Mar 18

Primary tabs

I shared some earlier reports - thru March 15 - here.  I continue to work my way thru the Japan reports from the horse's mouth, and attached are NISA reports March 16 17 18.  I will share more as I get thru more. 

Here, from my notes, are my sources of this information.

Date at beginning of sub-head is vintage of the official information.

Date in parentheses at end of each sub-head is when I got my hands on the info.


March 16 9 am Japan info (1 Mar 19)

The Government of Japan shares a situation report on response to the current situation,[1] as of March 16.  What happened, what’s being done about it, statistics. So far 114 countries and regions as well as 24 international organizations have expressed their intentions to extend assistance. (as of 9:00, March 16, 2011)

(1) After the earthquake and tsunami, control rods have been inserted immediately in the 11 reactors which were in operation in 3 nuclear power plants in Miyagi, Fukushima and Ibaragi Prefectures, automatically suspending power generation.

(2) With respect to TEPCO's Fukushima Dai-ichi and Dai-ni Nuclear Power Plants in Fukushima Prefecture, Nuclear Emergencies Situation was declared, and evacuations and introduction of emergency measures are undertaken. At Unit 1 of the Dai-ichi Nuclear Power Plant, a hydrogen explosion was observed at around 15:36 of March 12. However, it is thought that the Unit's containment vessel was not damaged.

(3) At 11:01 of March 14, a hydrogen explosion was observed in Unit 3 of the same Power Plant. The pressure of the unit's containment vessel fluctuated, but it is becoming stable. Therefore it is considered that the unit's containment vessel maintains its function. In Unit 2 of the same Power Plant, the cooling equipment of the reactor stopped on the same day, and preparations for measures of pouring in sea water are in progress in order to deal with the lowered water level.

(4) The Government of Japan has explained the situation to the diplomatic corps in Tokyo and foreign media and is providing necessary information to the IAEA in a timely manner.
