**// Chernobyl //**   

Chernobyl was a nuclear power plant in the Former Soviet union whose reactor core explded. It occured on April 26, 1986. There was a large release in radiation and over the course of the disaster 54 people died as a result of the radiation. In fact, the radiation fallout affected an area with a radius of 18.6 miles, and it flew in the wind to areas like Ukraine, Belarus, Russia, Scandanavia, and other parts of Europe. Scientists belive it to be the worst nuclear power disaster in history. __**    Causes:      **__     The reactor crew at Chernobyl-4 began preparing for a test to determine how long turbines would spin and supply power with a loss of electrical power supply. Tests had already been carried out at Chernobyl. These reactors were known to be very unstable at low power settings. As flow of coolant water diminished, power output increased. When the operator moved to shut down the reactor from its unstable condition, a design flaw caused a huge power surge. The fuel elements exploded and the force of steam lifted the cover plate off of the reactor which released fission products intoto the atmosphere. Another explosion threw out fragments of burning fuel and graphite from the core and allowed air to rush in. As a result the graphite moderator to burst into flames.   **__Laws and policies changed as a result of Chernobyl:__**   The Chernobyl accident sparked criticism of unsafe procedures and design flaws in Soviet reactors, and it heightened resistance to the building of more such plants. Chernobyl Unit 2 was shut down after a 1991 fire, and Unit 1 remained on-line until 1996. Chernobyl Unit 3 continued to operate until 2000, when the nuclear power station was officially decommissioned. Much criticism of unsafe nuclear plant procedures and design flaws of Soviet reactors resulted from the Chernobyl accident. Over time, units over Chernobyl were shut down. Even though the world was not ready for a disaster such as Chernobyl, its occurence led to a review of reactor safety and emergency planning in plants throughout the globe. Russians are now confident that they have properly brought new safety precautions so that there will not be a second Chernobyl. After Chernobyl, there are more stringent requirements in Russia on technical instillations and maintenance. Not only were new policies made in Russia, they were in other parts of the world as well. For example, the German Nuclear Safety Commission (RSK) carried out checks at all plants. Then, "catalytic remcombiners" were installed to prevent explosions.  //Health related effects because of Chernobyl//: Around 1986, organizations had problems naming the impacts of the Chernobyl accident due to the lack of public health information. But in 1989, the World Health Organization raised concerns that the intial predictions of health effects were wrong. So in 1991, the International Atomic Energy Agency studied the disaster. There were over one million people possibly affected by radiation. By 2000, 4000 cases of thyroid cancer were diagnosed in children. It is predicted that there may be an increased rate of leukaemia (due to Chernobyl) in the future.

 * Comments: The sources and information is very accurate and properly sighted. The wording can be a little confusing some times. It is also difficult to tell what some of the pictures are, but overall it is a very nice webpage.

The research is in depth and seems very accurate, however, I also agree that the wording could be altered so it is less confusing. The pictures are great. Good job guys : )

Your page is great, filled with acurate information, or as far as i can tell. The beggining is fantastic, with the name and the two pictures right there in your face. Like how you put all your biographical information all at the bottom in a neat, well organized, and how it also identifies the picture that you found there. Overall is just a good wiki page.**
