Spread this presentation by sharing to everyone so that the adverse effect of Nuclear Fission can be stopped otherwise the end of the days after tomorrow will come soon.
24. What happened? -Reactor No.4 was undergoing a test of the backup power supply in case of a power loss. -The experiment involved shutting down the coolant pumps, which caused the coolant to rapidly heat up and boil. -All control rods were ordered to be inserted . As the rods were inserted, they became deformed and stuck . The reaction could not be stopped. -The rods melted and the steam pressure caused an explosion , which blew a hole in the roof. A fire also resulted from the explosion. -To save money, the reactor was constructed with only partial containment , which allowed the radiation to escape. 13%-30% of the material escaped.
33. Fig. 15-21, p. 391 TRADE-OFFS Conventional Nuclear Fuel Cycle Large fuel supply Cannot compete economically without huge government subsidies Advantages Disadvantages Low net energy yield High environmental impact (with major accidents) Emits 1/6 as much CO 2 as coal Environmental costs not included in market price Risk of catastrophic accidents No widely acceptable solution for long-term storage of radioactive wastes Moderate land use Spreads knowledge and technology for building nuclear weapons Subject to terrorist attacks and Earth quake
34. Fig. 15-22, p. 392 TRADE-OFFS Coal vs. Nuclear Coal Nuclear Ample supply Ample supply of uranium High net energy yield Low net energy yield Very high air pollution Low air pollution High CO 2 emissions Low CO 2 emissions Much lower land disruption from surface mining High land disruption from surface mining High land use Moderate land use Low cost (with huge subsidies) High cost (even with huge subsidies)
Target Audience: Middle School Includes: General Description: Introduction to the concepts of radiation and biological damage as well as numerous waste related terms (23 slides)
