FUKUSHIMA -Workers entered the No. 1 nuclear reactor building in the Fukushima Daiichi electrical power plant Thursday for the initially time considering that a hydrogen explosion occurred outside the reactor container on March 12, each day right after the complicated was harmed by an enormous earthquake and subsequent tsunami, Tokyo Electrical Strength Co officials explained.
The employees set up 8 pipes connected to a ventilating unit with the adjacent turbine creating as part of efforts to cut back the higher degree of radioactive contamination inside the reactor developing by circulating air by way of a filter around the gadget, the officials reported.
The move is aimed at preventing workers from struggling internal radiation publicity when they perform on setting up a brand new cooling procedure in the No. 1 reactor, according to TEPCO, which operates the plant in Fukushima Prefecture.
On Thursday, a total of 12 workers with protective fits, masks and air packs broke up into 4 three-member groups to put in the pipes, when checking time spent inside the No. 1 reactor constructing as well as the radiation levels there to make confident they weren't heavily exposed to radioactive substances, in accordance on the officials.
The process is anticipated to lessen the focus of radioactive substances inside the creating to one-twentieth the present ranges since the air will undergo the pipes and with the filter, that can catch the substances, before going back to your reactor building.
Higher radiation ranges inside of the developing had prevented personnel from entering it. Radiation as much as 49 millisieverts per hour was detected inside of the reactor making on April 17 in the course of a survey utilizing a robot
