the Chernobyl accident

1. CHERNOBYL The worst nuclear accident in history APRIL 26, 1986 [Igor Kostin/Laski Diffusion] The Chernobyl nuclear power plant May 1986, a few weeks after the disaster, Retrieved 24 August 2025

2. LESSON LEARNT 1.The importance of safety 2.the global-teamwork solution to this disaster 3. The promotion of the scientific researches

3. The importance of safety “Chernobyl is a reminder that safety is not optional — it is the foundation of every scientific and industrial activity.”

4. the global-teamwork solution to this disaster

5. the global-teamwork solution to this disaster IAEA introduced new global safety standards. Cross-border monitoring systems established after Chernobyl. International research on radiation health effects and nuclear safety. Post-Chernobyl agreements strengthened safety culture worldwide.

6. The promotion of the scientific researches Reactor Type In the past, The Chernobyl use RBMK reactor, and it doesn’t have containment structure. Currently, we use PWR reactor , more stable design with strong containment structures.

7. The promotion of the scientific researches Safety Systems In the past, the safety system was insufficient. Workers and devices worked without even any protection. No containment, explosion released massive radioactive material. Currently, we use Multiple active and passive safety systems, Containment and emergency measures greatly reduce radioactive release even in severe accidents.
