Criticality accident
A criticality accident is an accident that involves the release of a large amount of radiation in a short period of time. This can occur when fissile material, such as uranium or plutonium, is brought together in a way that causes a chain reaction. Criticality accidents are rare, but they can have devastating consequences.
- The Tokaimura nuclear accident: In 1999, a criticality accident occurred at the Tokaimura nuclear power plant in Japan. The accident occurred when workers were processing uranium fuel for a nuclear reactor. The workers accidentally brought together too much uranium in one place, which caused a chain reaction. The accident released a large amount of radiation into the environment and three workers were killed.
- The Chernobyl nuclear disaster: In 1986, a criticality accident occurred at the Chernobyl nuclear power plant in Ukraine. The accident occurred during a safety test, when workers disabled some of the safety systems in the reactor. This caused the reactor to become unstable and eventually explode. The Chernobyl disaster released a large amount of radiation into the environment and caused the deaths of 31 people. It is considered to be the worst nuclear accident in history.
Criticality accidents are a serious hazard associated with the use of nuclear energy. It is important to have strict safety protocols in place to prevent these accidents from happening. The Tokaimura and Chernobyl accidents are examples of what can happen when safety protocols are not followed.
