Transcript of Japanese Nuclear Accident

Fukushima Daiichi Nuclear Disaster 福島第一原子力発電所事故 福島第一原子力発電所事故福島第一原子力発電所事故 福島第一原子力発電所事故福島第一原子力発電所事故 THE ACCIDENT WHEN? March 2011 WHERE? ŌOkuma, Fukushima, Japan WHAT HAPPAENED? This accident was a chain of events, all occurring in Japan after the Toōhoku earthquake and tsunami in 2011. There were many "equipment failures, nuclear meltdowns, and releases of radioactive materials", causing many casualties and health problems in that area. Cicely L d i a Sof a C S L HOW DOES FUKUSHIMA
IMPACT CHATTANOOGA? Sequoyah Nuclear Plant is located in Chattanooga, TN As a result of an earlier study, using U.S. Geological Survey fault data, the NRC found that the Sequoyah Nuclear Plant is located in the fourth-highest earthquake risk area within the United States.

The greatest concern at the Sequoyah site is flooding, which was also a concern at the Fukushima site because of the tsunami. In a worst-case scenario, Tennessee river would start flooding, and the flood would pull the Nuclear Plant's individual sand baskets apart. Repairs during a flood would be impossible.

The TVA is currently exploring permanent modifications that are environmentally friendly, which should be in place by the end of 2015.

History The quake was quickly followed by a tsunami with waves as high as 32 feet that swamped coastal areas in northeastern Japan, where most of the 1000 deaths initially reported occurred. Possible Future Impact Pressure inside the No. 1 boiling water reactor had risen when the main power and then the diesel engines powering its emergency cooling system failed. The government issued a state of emergency at 7:03 Friday evening, and thousands of people living within a 3-kilometer radius of the plant were evacuated. The evacuation area was later increased to 10 km and then 20 km, after reports that radiation had been leaked into the atmosphere. TEPCO later notified the government that the water-cooling system in its Fukushima Dai-2 plant, located 12 km north of the Dai-1 plant, had failed, and all four of its reactors had been shut down automatically. At 3:36 on 12 March, an explosion occurred in a reactor of the Fukushima Dai-1 plant, blowing off the roof and the upper part of the outer walls of the structure containing the reactor. By 6:48 p.m., the density of radiation around the structure rose to the level of 1015 microsieverts and it eventually fell further to 70.5 microsieverts. By midday Sunday that the cooling system controlling Fukushima Dai-1 plant’s No. 3 boiling water reactor had failed. There is much "radioactive contamination" of over 120 million pounds of food and over 5 million gallons of water and other beverages that we import from Japan each year. Fukushima Atomic History Fukushima & Chernobyl The Japanese government raised the rating of the crisis at the Fukushima Daiichi power plant from a level 5 to a level 7.

That's the highest possible level on the international scale used to evaluate the seriousness of nuclear incidents. The only other level 7 nuclear incident was the 1986 accident at the Chernobyl nuclear plant in Ukraine.

Even though both accidents were rated the highest possible level, the Chernobyl nuclear plant released 10 times more radiation than Fukushima.
Most experts agree that the two nuclear incidents are very different. After Japan was struck by its biggest-ever recorded earthquake on March11, and then was hit by a devastating tsunami an hour later, the country then faced a third catastrophe in the form of a nuclear meltdown. March 11, 2011 The earthquake and the tsunami caused many nuclear plants to shut down quite abruptly, one being the Fukushima Dai-1 plant. The Fukushima nuclear disaster showed us once again that nuclear reactors are fundamentally dangerous. They can cause significant damage to the environment.

None of the world’s 436 nuclear reactors are immune to human errors, natural disasters, or any of the many other serious incidents that could cause a disaster. Millions of people who live near nuclear reactors are at risk. http://www.npr.org/2011/04/12/135353240/fukushima-vs-chernobyl-what-does-level-7-mean 1. What two natural disasters resulted in the Japanese Nuclear Accident? 1. an earthquake & a tsunami http://www.bbc.co.uk/news/world-asia-pacific-13050228 Fukushima & Chernobyl The Japanese government raised the rating of the crisis at the Fukushima Daiichi power plant from a level 5 to a level 7.

Not many deaths are predicted for U.S. citizens, but it is expected for some to be diagnosed with cancer. When traveling overseas, Americans are also at risk since Japan dumped most of the radioactivity in the Pacific Ocean. Concluding Opinion This event had both positive and negative effects on humans. Of course, the utter destruction, cost of repairs, and lives lost were a part of the horrible tragedy, and should not be looked over. It is also important to remember that, despite the horrible aftermath, nuclear companies all over the world were once again reminded that nuclear power is extremely dangerous, and should be constantly monitored. Wydia, I put the invisible frames around your questions and answers so I could keep them separate. You can stretch them to fit your questions if you need to, just don't delete the frames. Thanks, gurr! Quiz Questions 3. The Sequoyah Nuclear Plant is located in the_________ earthquake risk area within the United States. 2. What does our nation import that contributes to radiation contamination? 4. Which released more radiation? The Chernobyl Nuclear Plant or the Fukushima Nuclear Plant? 4. Chernobyl released 10 times more radiation 5. How many deaths were reported after the tsunami and earthquake in 2011? 1000 deaths
