Three Mile Island accident (US – 1979) falls under scale 5 nuclear power plant accidents. More than 240 people were exposed to radiation when a junkyard dealer in Goiania, Brazil, broke open an abandoned radiation therapy machine and removed a small highly radioactive cake of cesium chloride. The accident took place on October 10, 1957 when a windscale fire ignited plutonium piles and contaminated surrounding dairy farms. Chalk River Laboratory (CRL) is a site of major research and development to support and advance nuclear technology, in particular CANDU reactor technology. A major task currently facing the 600 workers, troops and fire-fighters at the plant was dealing with an 8 inch crack in the concrete pit connected to No 2 reactor. In the battle to cool the overheated reactors and prevent a dangerous meltdown of the highly radioactive fuel rods, huge quantities of seawater have been used. It appears that concrete has failed to prevent the highly radioactive water from leaking into the sea and technicians have even resorted to using a mixture of absorbent polymer, sawdust and shredded newspaper, but that seems to have met with a similar lack of success.
Meanwhile The Independent quotes a new report from Maplecroft, the global risk analysts, that of the 422 nuclear power stations in the world, more than one in ten are situated in places that are deemed to be at high or extreme risk from tsunamis or earthquakes or both. Helen Hodge, Maplecroft's natural hazards analyst is quoted in The Independent as saying: ''Although Japanese nuclear facilities are particularly exposed, other countries could also face similar risks.
A good example is the ageing Russian-built plant about 18 miles from the Armenian capital of Yerevan.
The risk of future natural disasters has been recognised by the International Atomic Energy Authority (IAEA) and the Japanese disaster has reignited the debate over nuclear safety.
IAEA consultant Dr Gordon Woo predicts that in the light of the Japanese disaster there will now be an upsurge in the transfer of seismic technology to less advanced nations. We have mentioned the state of the great river frequently, but the Mekong generally becomes more dammed and less likely to provide for its people and wildlife.


When can he climate changers and the global de-warmers finally have their way and be able to replace the whole carbon footprints of nations? What stories are appearing from the genomes of various creatures that can be mixed up with our histories. When dolphins are 'rescued' in various countries, the car given seems to be ill-considered. 2.The significance of this accident was because there a number of equipment  failures, nuclear meltdowns, and releases of radioactive materials. Picture sharing: Personally and honestly, I did not want to to see such event like the above picture happen again. On March 28, 1979, in the wee hours of morning, the Three Mile Island nuclear generating station witnessed a nuclear meltdown of one secondary loop.
It is thought that this crack could be responsible for the seepage of radioactive iodine into the sea. A major problem has been that this contaminated runoff has prevented technicians from getting close enough to the reactors in order to make proper repairs. As a result, several countries including Switzerland, Italy and Germany have put new reactor plans on hold. However, good news cannot be ignored in this case and it is really cheering to hear of 3 calves born during this dry season in the freshwater stretches of the river.
Well, there is hope in some of the latest renewable investments and this example of pure science that will soon be transferred to a new set of technologies.
Burning and destruction not only cause people’s lives, also wasting money and time to rebuild. This nuclear accident released 13 million curies of radioactive gases into the atmosphere and caused a loss of USD 2,400.


This was the worst nuclear accident in Britain’s history, ranked in severity at level 5 on the 7-point International Nuclear Event Scale. There is hope that the other populations, in Bangladesh and Myanmar, for example, are also being protected as well as this. They could even end up in commercial aquarium shows, but they certainly rarely make it back to the sea. It was the Fukushima Daiichi nuclear disaster, which occurred in Japan and the pictures shown above was the incident.
10 court cases were also filed on various authorities, concerning this accident, and they took 15 long years to get settled.
The fire released an estimated 20,000 curies of iodine-131, as well as 594 curies of caesium-137 and 24,000 curies of xenon-133, among other radionuclides. A series of hydrogen gas explosions hurled the four-ton gasholder dome four feet through the air where it jammed in the superstructure. Many children got attracted to the bright blue of the radioactive material, touched it and rubbed it on their skin, resulting in the contamination of several city block.
The core of the NRX reactor could not be decontaminated; it had to be buried as radioactive waste.
Navy, was among the hundreds of Canadian and American servicemen who were ordered to participate in the NRX cleanup following the accident.
