Six people working at the site of crippled Fukushima power plant have
been exposed to radiation after one of them mistakenly removed a pipe
connected to a contaminated water treatment system. It’s the second
incident at Fukushima in three days.
The accidental pipe detachment on Wednesday resulted in the leak of
several tons of water, which Fukushima operator TEPCO uses to cool the
The water came from a system which removes salts from the cooling
liquid after it comes out from the damaged reactors. The leakage
continued for some 50 minutes. Reuters estimates that at least seven
tons of water escaped the system.
The Nuclear Regulation Authority told the news agency that the
incident was equivalent to “Level 0″ on the International Nuclear and
Radiological Events Scale (INES), but did not give an official rating.
TEPCO would not immediately report on the conditions of the six workers exposed to the water following the incident.
Earlier this week a worker accidentally switched off a water pump used to channel water into the reactor building.
Leakages of contaminated water have been plaguing Fukushima in the
latest months as TEPCO fails to prevent radiation from being released
into the environment.
