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 reactors.

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.

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.
