Nuclear Energy :: essays research papers fc
You are watching the control panels and gages for rector two. Sitting comely you think about how easy your job is. It is a joke! All day you sit around and watch the gages for reactor number two just to make sure they maintain their settings. You don't even need to look at the gages either because a computer automatically regulates them without you. Life is so good. Suddenly all the sirens go of and the gages and displays spin wildly in every direction. The ground shakes and you can hear the sound of a deep rumble. Unknown to you, the reactor's cooling pumps have failed to cool the reactor's core and in 3 seconds the temperature went from 280 degrees centigrade to 4,000 degrees centigrade. The water that was in the reactor is instantly turned to steam which creates tremendous amount of pressure in the reactor core. Above the reactor core there is a 5 foot thick lead plate and above that there is a meter thick floor composed of iron, barium, serpentine, concrete, and stone. The exploding steam fires the floor up like shrapnel. The metal plate goes through the four foot thick concrete roof like butter and reaches and altitude of sixty meters. You can hear ripping, rending, wrenching, screeching, scraping, tearing sounds of a vast machine breaking apart. L. Ray Silver, a leading author who covered the disaster at Chernobyl, said that within the core, steam reacts with zirconium to produce that first explosive in nature's arsenal, hydrogen. Near-molten fuel fragments shatter nearly incandescent graphite, torching chunks of it, exploding the hydrogen. The explosion breaks every pipe in the building rocking it with such power that the building is split into sections (11-13). You look down at your body and notice that it feels hot and your hands look different. Unknown to you a tremendous amount of neutrons are hitting your cells and taking chucks out of your skin. Suddenly everything goes black.The paragraph above describes the scene of what happened at Chernobyl nuclear plant a few years ago. From that time until the present many other smaller accidents have happened. From these accidents many people have died and millions have been indirectly affected. Nuclear energy has far to many negative problems than advantages. From the mining of uranium to disposal of nuclear waist there are problems of such magnitude that no scientist on this earth has an answer for.
