O e-mail abaixo corresponde ao dia 12 de Junho de 2011, e tem a particularidade de assinalar os “três meses depois do acidente”. Se o leitor estiver interessado na totalidade da informação, pode solicitá-la directamente ao Dr. Nakamura (koichi.nakamura@aist.go.jp). Pessoalmente, posso disponibilizar a compilação dos e-mails do Dr. Saji, mas sem anexos PDF (edmartinho@clix.pt).

Dear Colleagues:
92nd day!
I. Three months since the earthquake
On this occasion, most news media issued a series of special feature of the consequence of the Higashi-Nihon (Eastern Japan) Great Earthquake series. All pointed out that the recovery activities are very slow. Most of them pointed out that delay in disposal of tsunami debris is one of the biggest obstacle for recovery operation. In addition, 91,000 people are still in refuges. Although 28,700 temporary housings have been completed, only 17,000 of them are occupied. For evacuated people, some of the temporary housings are located in inconvenient places, nor necessary social infrastructure has not been recovered yet. For example, as many as 57, 900 houses are not provided with the city water service yet. More serious issue is nearly a half of the evacuated people became pessimistic for returning to where they have been living.
From this point of view, there is no prospect in sight in the planning for recovery and resettlement of the evacuated zones.
In the “emergency preparedness” zone, there are 153 industrial facilities, in which no one has prospect for re-opening. Everything depends on when the damaged plants became under control. From this point of view, increased number of workers are getting out of condition due to working in air tight radiation protection suits in hot weather, such as due to dehydration. The improvement of working environment is becoming an urgent issue and some rest areas have been constructed. They are now provided with a pack of refrigerant. During the hot season, there will be a rest hours in the hottest afternoon hours.
The total volume of the highly contaminated water continues to be increasing. The pre-functional test of the new water purification system has not been started yet, due to miniscule leakages at the zeolite sorption stage. The leaky valves and flanges have been ameliorated by putting sealing compounds around the joints. This can be seen in the updated set of photos uploaded by TEPCO: http://www.tepco.co.jp/en/news/110311/index-e.html please visit “Coupling Parts of Inlet and Outlet of Cesium Adsorption Tower (pictured on June 9, 2011)”

II. Recapping on removing contamination from 1F2 reactor building
In 1F2, the moisture level is as high as 99.9%. Combined with the high dose rate, the worker entry is greatly restricted. In view of this, TEPCO has started to decontaminate the room air by employing the heated filtering system used in entering into 1F1 by improving to add heaters. For that the double doors from the turbine building has been opened at 12:39 on June 11. After a few days of operation, they plan to open the truck entrance door, facilitating the natural draft ventilation. By opening the door, some contamination may also leak out to the environment. By exchanging the room air by natural ventilation, TEPCO hopes to allow the worker entrance.
TEPCO uploaded a series of photos in their website: http://www.tepco.co.jp/en/news/110311/index-e.html
This is the first time that a set of relatively clear photos became available inside of this building. The photos were shown in *pictured through vinyl which covers the camera on June 11, 2011”.

In Unit 2, the air cooler has been installed and working for the spent fuel pool.
III. Recapping on inspection of 1F3 reactor building
Also, http://www.tepco.co.jp/en/news/110311/images/110611_001e.pdf is showing a map of radiation level data taken along the route of the inspection, http://www.tepco.co.jp/en/news/110311/images/110611_06.jpg is showing that the dose rate was higher near the large machine hatch. http://www.tepco.co.jp/en/news/110311/images/110611_07.jpg shows that the water treatment skid may not be accessible for workers for piping.
IV. Recapping on inspection of 1F4 reactor building
A set of photos taken by entering into the 1F4 is also uploaded in the TEPCO website. The “4th Floor of Unit 4 Reactor Building (pictured on June 10, 2011) Pictured at South Side on 4th floor of Unit 4 Reactor Building”
http://www.tepco.co.jp/en/news/110311/images/110611_04.jpg is showing that a part of the piping of Spent Fuel Cooling and Cleaning System is bent, perhaps may not be usable for installation of the air cooling system.

Well let me stop here.
