  1. Chernobyl By Alyssandra Chavez & Francisco Penaloza

  2. Before Explosion

  3. After Explosion

  4. LOCATION OF cHERNOBYL • About 110 ten kilometres north of Kiev, near Belarus border. • Populationof about 49,000

  5. LOCATION OF CHERNOBYL

  6. what the nuclear plant was used for • to create fuel more rapidly and more efficiently  by using the RBMK 1000

  7. the rbmk 1000

  8. how the RBMK 1000 works • The RBMK-1000 is a Soviet-designed and built graphite moderated pressure tube type reactor and uses uranium dioxide fuel.  • The core itself is about 7 m high and about 12 m in diameter.  • The power output of this reactor is 3200 MW thermal, or 1000 MWe  • Various safety systems, such as an emergency core cooling system, were incorporated into the reactor design.

  9. what happened?! • April 26 started off with the crew at Reactor 4 preparing for testing how the long turbines would contribute to a supply of power to the main circulating pumps • While doing this, the automatic shutdown mechanisms were disabled • By the time that the operator moved to shutdown the reactor, the reactor was in an extremely unstable condition.

  10. WHAT HAPPENED?! • The hot liquid mixing with the cool water caused a fragmentation and increased in pressure which cause the cover plate to be partially detached • Intense steam generation then spread  throughout the whole core (fed by water dumped into the core due to the rupture of the emergency cooling circuit) causing a steam explosion and releasing fission products to the atmosphere. • Shortly afterwards there was another explosion

  11. WHAT HAPPENED?! • The fire was so intense that the glowing reactor could be seen from space

  12. consequences! • high levels of UV radiation were released into atmosphere • increased rates of thyroid cancer to individuals exposed to the radiation • 31 deaths • 49, 360 people evacuated

  13. consequences! :O • not liveable for another 20,000 years • has to be inspected for radiation leaks • Efforts to contain the contamination and prevent a greater catastrophe involved more than 500,000 workers and cost 18 billion rubles

  14. CHERNOBYL TODAY • some people refused to leave • persons younger than 18 are not allowed there • people can obtain tourists passes • workers are only allowed in for limited hours every month • nature took over town

  15. chernobyl today This is the monument to the rescuers of the city who were the first who came to the accident site. Every year in April, 26 thousands of people come to the monument
