 * Details:**
 * Happened on April 26,1986 at 1:23:44 a.m in Ukrainian SSR
 * It is the worst nuclear power pant accident to date
 * There were 2 deaths in the intial blast but many deaths came afterwards do to the fallout, and 28 were killed from immediate radiation
 * It was reactor number 4 that exploded
 * After the explosion some workers body's were never found
 * Large areas in the Ukraine, Belarus, and Russia were contaminated
 * 60% of the radioactive fallout landed in Belarus
 * There have been 4,000 more cancer case found because of the radioactive fallout
 * Causes of the Chernobyl diaster:**
 * It happened because of a flawed Soviet reactor design
 * There was a shortage of water to cool the urainum fuel
 * This then led to overheating of the fuel rods
 * Then the uranium-oxide fuel began to melt
 * Then the operators flooded the reactor making all the water turn into steam this reacted with the graphite fuel and zirconium to produce hydrogen, methane, and carbon monoxide
 * This led to a deadly explosion of the reactor
 * So it was serious mistakes made by plant operators with minimum training
 * What are they doing about it?:**
 * The Chernobyl unit 4 is now enclosed in a large concrete shelter
 * They dropped loads and loads of lead, sand, and boron to cover the plant but it didn't work to put the fire out
 * A New Safe Confinement structure will be built by the end of 2011, It is to be an 18,000 tons metal arch 105 meters high, 200 meters long and spanning 257 meters, to cover both unit 4 and the hastily-built 1986 structure.
 * Although the Chernobyl accident was terrible and unfortunate, we have learned a lot from the accident and are using that knowledge to improve other plants around the world.
 * The U.S. formed The Convention on Nuclear Safety, The Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management and The Compensation Convention: Path to a Global Regime for Dealing with Legal Liability and Compensation for Nuclear Damageto prevent this diaster from happening again
