The Concequenses and Impacts of Chernobyl AccidentAbstractIntroductionCronology Impacts & Consequences LessonsChernobyl accident was the worst nuclear accidentin the world. It happened because the proceduralerror. It was affect badly to the environment,peoples healthy and also social economic. Inspiteof its bad impact there was many lessons learnhave to taken to enhance the nuclear itself for ourbetter future. By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University 4. The Concequenses and Impacts of Chernobyl AccidentAbstractIntroductionCronology Impacts & Consequences LessonsThe 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% Ukraines electricity Due to the error of procedural, accident occuredOn 26 April 1986 and released radioactivematerials By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University 5. The Concequenses and Impacts of Chernobyl AccidentAbstractIntroductionCronology Impacts & Consequences LessonsOn 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 MWTAt 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. The Concequenses and Impacts of Chernobyl Accident AbstractIntroductionCronology Impacts & Consequences Lessons At 01:19 the operator tries raise the pressure and waterlevel using a pump feeder. At 01.19,30 a water level required in the steam drum isreached, but operators continue to add water feeder. At 01.22,30 operators see parameters on the reactorsystem monitor. The data show that the operator mustshutdown reactor in a situation automatic shutdownmechanism is not such work. But what happensoperators continue to experiment.nextBy : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University 7. The Concequenses and Impacts of Chernobyl AccidentAbstractIntroductionCronology Impacts & Consequences Lessons At trial 01.23,04 begins again with the 200 MWT, and main steamflow valve to the turbine number 8 is turned off. After a while then the reactor power raises fast but it solate to shutdown reactors because alarm was sounded. Emergency system is not able to cope with theseconditions, Less than a second after the first explosion asecond explosion followed immediately caused by entry ofair into the terrace which causes the fuel and someelements react with oxygen and burn awesome. next By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University 8. The Concequenses and Impacts of Chernobyl AccidentAbstractIntroductionCronology 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, economyEnvironmentPositive By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University 9. The Concequenses and Impacts of Chernobyl AccidentAbstractIntroductionCronology Impacts & Consequences Lessons In total some 200,0000 people are believed to have been relocated as a result of the accident. nextHealthy Social, economyEnvironmentPositive By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University 10. The Concequenses and Impacts of Chernobyl AccidentAbstractIntroductionCronology Impacts & Consequences Lessons Three categories of populations who are exposed radiation caused bythe 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 contaminatednext3. Residents who live in the area contaminated but not evacuated.Healthy Social, economyEnvironmentPositive By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University 11. The Concequenses and Impacts of Chernobyl AccidentAbstractIntroductionCronology Impacts & Consequences LessonsRadioactive elements which were emitted into the environment : Iodine, strontium and caesium. Strontium-90 and Caesium-137 Strontium ,iodin, caesiumnext Healthy Social, economyEnvironmentPositive By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University 12. The Concequenses and Impacts of Chernobyl AccidentAbstractIntroductionCronology Impacts & Consequences LessonsArea 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, economyEnvironmentPositive By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University 13. The Concequenses and Impacts of Chernobyl AccidentAbstractIntroduction 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.HealthSocial EconomyEnvironmentPositiveBy : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University 14. The Concequenses and Impacts of Chernobyl AccidentAbstractIntroductionCronologyImpacts & Consequences Lessons LeukemiaAn 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). nextHealthSocial EconomyEnvironmentPositiveBy : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University 15. The Concequenses and Impacts of Chernobyl AccidentAbstractIntroduction Cronology Impacts & ConsequencesLessons 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. nextHealthSocial EconomyEnvironmentPositiveBy : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University 16. The Concequenses and Impacts of Chernobyl AccidentAbstractIntroduction Cronology Impacts & ConsequencesLessons Non-Cancer and Non-Thyroid health effects Cataracts Cardiovascular diseases Cryptogenic biomarkers and their significance Immunological system effects Heritable effects, birth defects and childrens health Mental, Psychological and central nervous system effects Estimation of mortality attribute to the Chernobyl accident. Medical programmers and medical monitoring (screening).Health Social EconomyEnvironment Positive By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University 17. The Concequenses and Impacts of Chernobyl AccidentAbstractIntroductionCronology 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 costHealthSocial, Economy EnvironmentPositive By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University 18. The Concequenses and Impacts of Chernobyl AccidentAbstractIntroductionCronology Impacts & ConsequencesLessons The town becomes a ghost town, no one live there. They move to save placeIn agriculture site, the level of radioactivity of agriculturalplants and plant-consuming animals was dominated bysurface deposits of radio nuclidesRadioactive material contaminated the aquatic systems andabsorbed to the soil. Its affect the creature in that aquaticsystem.HealthSocial, EconomyEnvironmentPositive By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University 19. The Concequenses and Impacts of Chernobyl AccidentAbstractIntroductionCronology 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 ofaccidents 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.HealthSocial, EconomyEnvironmentPositive By : Group Seven, Nuclear Engineering, Faculty of Engineering, Gadjah Mada University 20. The Concequenses and Impacts of Chernobyl AccidentAbstractIntroductionCronology Impacts & Consequences LessonsReview from the case above, nuclear accident in Chernobyl, has implicit senses: DO Professionally Be CarefulPrepare solution of any Possibility Determining minimum distance from the reactor to publicplace.
