Title: Radiation high near suppression chambers
Date: Thursday, March 15, 2012 12:42 +0900 (JST)
High levels of radiation have been detected near suppression chambers of 2 of the reactors at the Fukushima Daiichi nuclear plant.
The radiation levels are too high for workers to continue inspections.
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. [...]
Tokyo Electric says robots are needed for future inspections because the radiation levels at the 2 reactors are too high for workers to carry out repairs. [...]
- 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
