CHERNOBYL NEUCLEARDISASTEROccurred on 26 April 1986 at Chernobyl Nuclear Power Plant in Ukraine. An explosion and fire released large quantities of radioactive contamination into the atmosphere ,whichspread over much of Western USSR and Europe.
Causes Operator error initially faulted The operator error was probably due to their lack of knowledge of nuclear physics and engineering, as well as lack of experience and training. Operating instructions and design deficiencies found There actor had a dangerously large positive void coefficient.The void coefficient is a measurement of how are actor responds to in creased steam formation in the water coolant. A more significant flaw was in the design of the control rods that are inserted into there actor to slow down there action. Other deficiencies besides these were not edinreactor design ,as were its non-compliance with accepted standards and with the requirements of nuclear reactor safety.
Impact on People Economic impact Removal of radiation affected agricultural and forest land from production. Hugh amount of money in Belarus and Ukraine used for Chernobyl related benefits. Agricultural production costs have increased due to the need for special cultivation techniques , fertilizers and additives.
What happened SATURDAY APRIL 26,1986 Reactor #4 was undergoing a test to test the backup power supply in case of power loss The power fell to low allowing the concentration of xenon 135 to rise The workers continued the test and in order to control the rising levels of xenon 135,the controlled rods were pulled out.
The Reactor after the ExplosionAfter the explosion , most of the plant is still standing . Some might think from this picture that the disasterwasn’t all that bad, but what makes the Chernobyldisaster the worst in historyis the sheer volume of radio active materials that wherespewed across the European continent .
AftermathOnly 30 people died due to the accident at Chernobyl, with 2 of those 30 dying because of the foremost explosions.The accident released tons of toxic into the environment,which spread all over EUROPE.The event gained much negative media attention and was much dramatized to represent countless mutations due to the accident,although this is far from the truth.
