  3. 3. The Concequenses and Impacts of Chernobyl AccidentAbstract Introduction Cronology Impacts & Consequences LessonsChernobyl accident was the worst nuclear accidentin the world. It happened because the proceduralerror. It was affect badly to the environment,people’s healthy and also social economic. Inspiteof its bad impact there was many lessons learnhave to taken to enhance the nuclear itself for ourbetter future.

  4. 4. The Concequenses and Impacts of Chernobyl AccidentAbstract Introduction Cronology Impacts & Consequences Lessons The Chernobyl Nuclear Power Plant  Located 11 miles north of the city of Chernobyl  Developed since 1954, and operated 1973-1975  Consist of 4 RMBK reactors  Produced 10% Ukraine’s electricity  Due to the error of procedural, accident occured On 26 April 1986 and released radioactive materials By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University
  5. 5. The Concequenses and Impacts of Chernobyl AccidentAbstract Introduction Cronology Impacts & Consequences Lessons•On midnight 25 April 1986 trial is started. Reactor powerwas reduced to 1600 MWT.•At 0:28 am April 26 to power down again and operatormade a mistake ACS setting, so that the reactor powerdrops drastically to only 30 MWT•At 1:00 oclock the operator managed to raise reactorpower to be 200 MWT by lifting number of control rodsfrom the reactor. next By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University
  6. 6. The Concequenses and Impacts of Chernobyl Accident Abstract Introduction Cronology Impacts & Consequences Lessons• At 01:19 the operator tries raise the pressure and water level using a pump feeder.• At 01.19,30 a water level required in the steam drum is reached, but operators continue to add water feeder.• At 01.22,30 operators see parameters on the reactor system monitor. The data show that the operator must shutdown reactor in a situation automatic shutdown mechanism is not such work. But what happens operators continue to experiment. next By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University
  7. 7. The Concequenses and Impacts of Chernobyl Accident Abstract Introduction Cronology Impacts & Consequences Lessons• At trial 01.23,04 begins again with the 200 MWT, and main steam flow valve to the turbine number 8 is turned off.• After a while then the reactor power raises fast but it so late to shutdown reactors because alarm was sounded.• Emergency system is not able to cope with these conditions, Less than a second after the first explosion a second explosion followed immediately caused by entry of air into the terrace which causes the fuel and some elements react with oxygen and burn awesome. next By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University
  8. 8. The Concequenses and Impacts of Chernobyl AccidentAbstract Introduction Cronology Impacts & Consequences Lessons The initial explosion resulted in the death of two workers. next Twenty-eight of the firemen and emergency clean-up workers died in the first three months Healthy Social, economy Environment Positive By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University
  9. 9. The Concequenses and Impacts of Chernobyl AccidentAbstract Introduction Cronology Impacts & Consequences Lessons • In total some 200,0000 people are believed to have been relocated as a result of the accident. next Healthy Social, economy Environment Positive By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University
  10. 10. The Concequenses and Impacts of Chernobyl AccidentAbstract Introduction Cronology Impacts & Consequences Lessons Three categories of populations who are exposed radiation caused by the Chernobyl accident are:1. Emergency workers and liquidators (recovery operation workers) who worked in the Chernobyl reactor and are in the exclusion zone after the accident2. Residents who were evacuated from the area contaminated next3. Residents who live in the area contaminated but not evacuated.

The Concequenses and Impacts of Chernobyl AccidentAbstract Introduction Cronology Impacts & Consequences LessonsRadioactive elements which were emitted into the environment :  Iodine, strontium and caesium.  Strontium-90 and Caesium-137  Strontium ,iodin, caesium next Healthy Social, economy Environment Positive By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University
  12. 12. The Concequenses and Impacts of Chernobyl AccidentAbstract Introduction Cronology Impacts & Consequences Lessons Area was affected by the radioactive fallout:  An area spanning 30 kilometres  Some 150,000 square kilometres in Belarus, Russia and Ukraine  other region Healthy Social, economy Environment Positive By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University
  13. 13. The Concequenses and Impacts of Chernobyl AccidentAbstract Introduction Cronology Impacts & Consequences LessonsThyroid Cancer One of the principal radionuclides released by the Chernobyl accident was iodine-131, which was significant for the first months. The thyroid gland accumulates iodine from the blood stream as part of its normal next metabolism.

  14. 14. The Concequenses and Impacts of Chernobyl AccidentAbstract Introduction Cronology Impacts & Consequences Lessons Leukemia An increased risk of leukemia associated with radiation exposure from Chernobyl was, therefore, expected among the populations exposed. The most recent studies suggest a two-fold increase in the incidence of non-CLL leukemia between 1986 and 1996 in Russian emergency and recovery operation workers exposed to more than 150 mGy (external dose). next Health Social Economy Environment Positive By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University
  15. 15. The Concequenses and Impacts of Chernobyl AccidentAbstract Introduction Cronology Impacts & Consequences Lessons Solid cancer different from Thyroid Cancer and Leukimia. Solid Cancer Its because their different in sensitivity to radiation in terms of the minimal latency period, the time dependency of risk and the dose-response relationship. The data of solid cancer caused by Chernobyl accident placed in UNSCEAR 200. And its not have any kind of change until now. next Health Social Economy Environment Positive By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University

  17. 17. The Concequenses and Impacts of Chernobyl AccidentAbstract Introduction Cronology Impacts & Consequences Lessons The disaster has placed a huge burden on national budget, the expenditure related to:• Actions to seal off the reactor• Resettlement of people and construction• Social protection and health care• Research on environment, health and production of clean food• Radiation monitoring• Radioecological improvement• losses relating to the opportunity cost Health Social, Economy Environment Positive By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University
  18. 18. The Concequenses and Impacts of Chernobyl AccidentAbstract Introduction Cronology Impacts & Consequences Lessons The town becomes a ghost town, no one live there. They move to save place In agriculture site, the level of radioactivity of agricultural plants and plant-consuming animals was dominated by surface deposits of radio nuclides Radioactive material contaminated the aquatic systems and absorbed to the soil. Its affect the creature in that aquatic system. Health Social, Economy Environment Positive By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University
  19. 19. The Concequenses and Impacts of Chernobyl AccidentAbstract Introduction Cronology Impacts & Consequences Lessons Positive impacts of the accident:Chernobyl accident became a reference point for the construction of nuclear powerplantsIn the progress of next-generation NPP such as PWR, BWR, CANDU, AGR, ABWR, System 80 + and FBR, the principle of safety is to prevent the possibility of accidents and to minimize the impact if an accident occursNuclear power plants is designed to be able to withstand extreme incidentChernobyl accident does not make the trauma and stop all nuclear activities but rather spur them to further improve safety culture and reactor design safety.
