Update to Information Sheet Regarding the Tohoku Earthquake

The Federation of Electric Power Companies of Japan (FEPC) Washington DC Office

As of 1:00PM (EST), March 14, 2011

• Radiation Levels
• At 9:37AM (JST) on March 14, a radiation level of 3130 micro sievert was recorded at the Fukushima Daiichi Nuclear Power Station.
• At 10:35AM on March 14, a radiation level of 326 micro sievert was recorded at the Fukushima Daiichi Nuclear Power Station.
• Most recently, at 2:30PM on March 15, a radiation level of 231 micro sievert was recorded at Fukushima Daiichi Nuclear Power Station.
• Fukushima Daiichi Unit 1 reactor
• As of 12:00AM on March 15, the injection of seawater continues into the primary containment vessel.
• Fukushima Daiichi Unit 2 reactor
• At 12:00PM on March 14, in response to lower water levels, TEPCO began preparations for injecting seawater into the reactor core.
• At 5:16PM on March 14, the water level in the reactor core covered the top of the fuel rods.
• At 6:20PM on March 14, TEPCO began to inject seawater into the reactor core.
• For a short time around 6:22PM on March 14, the water level inside the reactor core fell below the lower measuring range of the gauge.  As a result, TEPCO believes that the fuel rods in the reactor core might have been fully exposed.
• At 7:54PM on March 14, engineers confirmed that the gauge recorded the injection of seawater into the reactor core.
• At 8:37PM on March 14, in order to alleviate the buildup of pressure, slightly radioactive vapor, that posed no health threat, was passed through a filtration system and emitted outside via a ventilation stack from Fukushima Daiichi Unit 2 reactor vessel.
• Fukushima Daiichi Unit 3 reactor
• At 11:01AM on March 14, an explosion occurred at Fukushima Daiichi Unit 3 reactor damaging the roof of the secondary containment building. Caused by the interaction of hydrogen and oxygen vapor, in a fashion to Unit 1 reactor, the explosion did not damage the primary containment vessel or the reactor core.
• As of 12:38AM (JST) on March 15, the injection of seawater has been suspended.
• Fukushima Daini Unit 1 reactor
• As of 1:24AM on March 14, TEPCO commenced the cooling process after the pumping system was restored.
• At 10:15AM on March 14, TEPCO confirmed that the average water temperature held constant below 212 degrees Fahrenheit.
• Fukushima Daini Unit 2 reactor
• At 7:13AM on March 14, TEPCO commenced the cooling process.
• As of 3:52PM on March 14, the cooling function was restored and the core temperature was stabilized below 212 degrees Fahrenheit.
• Fukushima Daini Unit 3 reactor
• As of 12:15PM on March 13, reactor has been cooled down and stabilized.
• Fukushima Daini Unit 4 reactor
• At 3:42PM on March 14, cooling of the reactor commenced, with TEPCO engineers working to achieve cold shutdown.
