High radiation at Fukushima Daiichi nuclear plant

High levels of radiation have been detected near suppression chambers of two of the reactors at the Fukushima Daiichi nuclear plant. The radiation levels are too high for workers to continue inspections, Japan's NHK website reported. Decommissioning the plant's crippled reactors involves filling the reactors and their containment vessels with water and extracting melted fuel. To do this, workers must pinpoint and repair damage to the containment vessels and the suppression chambers. On Wednesday, for the first time since the accident a year ago, Tokyo Electric Power Company sent workers to the basement of the No.2 and No.3 reactor buildings to examine the suppression chambers. A total of six employees entered. At the No.2 reactor building, workers opened the door to the suppression chamber and detected a maximum radiation of 160 millisieverts per hour. The door to the chamber at the No.3 reactor had been damaged and could not be opened. The maximum radiation outside the door was 75 millisieverts per hour.
