Fukushima Daiichi NPS Prompt Report 2013

Fukushima Daiichi NPS Prompt Report (May 10, 2013)Smoke from Near the North Side of Unit 6 at Fukushima Daiichi Nuclear Power Station

At around 9:25 AM today (May 10), a cooperative company worker found smoke coming out from near the mobile temporary toilet installed in the north side (outside) of Unit 6 at Fukushima Daiichi Nuclear Power Station.

The incident was reported to the fire department at 9:35 AM. (Since we judged that the incident was not a fire, site investigation was not done by the fire department.)

Upon site investigation, black smoke was found to be coming out from the exhaust stack of the engine generator installed in the mobile temporary toilet as the power supply for ventilation. The smoke was confirmed to have stopped coming out after suspending the generator.

As a result of site investigation, the smoke was identified to be the gas exhausted from the engine generator turning black due to oil loss via the piston ring of the engine generator. Thus, we have judged that this incident was not a fire.
