The robot in action yesterday in central Fukushima Daiichi have measured high levels of radioactivity in buildings No. 1 and No. 3 reactor, recording values that make it extremely difficult for the direct intervention of technicians TEPCO on the premises. As reported today by Japan's Atomic Safety (Nisa) in reactor No.
1 was detected radioactivity level is 10 to 49 millisieverts per hour, while the No. 3 reactor have been reported even higher values, from 28 to 57 millisieverts per hour, compared to an average of 0.01 in normal millisievert per hour. "In this situation it is very difficult for the engineers of the plant to carry out their work from the inside - said the agency spokesman, Hidehiko Nishiyama -.
Somehow you must first reduce the level of radiation and screen. The maximum level of radiation allowed for the engineers to work in central failure is 250 millisievert, a limit that in the case of the space of the reactor No. 3 would be exceeded in about four and a half hours. The latest measurements were made by the robots remotely controlled from the United States, pledged on Sunday to examine the buildings that house the reactors in order to understand what their current conditions: among other data received so far is the temperature, 28-29 degrees for the reactor no.1 and 19-22 degrees for the No.
3 reactor, while the concentration of oxygen is 21% in both spaces. The TEPCO has confirmed that it will take three months to get "settled down" the escape of radiation from the plant in Fukushima Daiichi.
