Tokyo, March 21 (Jiji Press)—A radiation level of 11 sieverts per hour has been detected in tainted water inside a reactor containment vessel at the Fukushima Daiichi nuclear power plant, operator Tokyo Electric Power Company Holdings Inc. said Tuesday.
The reading was measured in a survey using a robot on Sunday at a point some 30 centimeters above the bottom of the containment vessel of the plant’s number 1 reactor.
This is the highest radiation level detected in water inside the containment vessel.
TEPCO said it remains unknown whether melted nuclear fuel debris exists at the point, where the company previously said there was apparently no debris left.
The plant’s number 1, 2, and 3 reactors suffered meltdowns in March 2011 after it was hit by a massive earthquake and tsunami.
