Satellite image of the reactor and surrounding area in April 2009. The Chernobyl Nuclear Power Plant Zone of Alienation, [a] also called the 30-Kilometre Zone or simply The Zone, [5]: p.2–5 [b] was established shortly after the 1986 Chernobyl disaster in the Ukrainian SSR of the Soviet Union.
Containment happens when barriers, known as firebreaks, get in the way of a fire’s forward momentum. Sometimes those barriers are natural, like rivers or terrain without burnable fuel.
The heavy case is secured with tamper-resistant bolts to deter unauthorized opening of the case. The International Electrotechnical Commission publishes the 60079 series of standards [ 2 ] which defines a system for classification of locations, as well as categorizing and testing of equipment designed for use in hazardous locations, known as ...
Containment systems for nuclear power reactors are distinguished by size, shape, materials used, and suppression systems. The kind of containment used is determined by the type of reactor, generation of the reactor, and the specific plant needs. Suppression systems are critical to safety analysis and greatly affect the size of containment.
The Chernobyl Nuclear Power Plant sarcophagus or Shelter Structure (Ukrainian: Об'єкт "Укриття") is a massive steel and concrete structure covering the nuclear reactor number 4 building of the Chernobyl Nuclear Power Plant.
A hazard map is a map that highlights areas that are affected by or are vulnerable to a particular hazard. They are typically created for natural hazards , such as earthquakes , volcanoes , landslides , flooding and tsunamis .
The word confinement is used rather than the traditional containment to emphasize the difference between the containment of radioactive gases—the primary focus of most reactor containment buildings—and the confinement of solid radioactive waste, which is the primary purpose of the New Safe Confinement.

Environmental remediation is the cleanup of hazardous substances dealing with the removal, treatment and containment of pollution or contaminants from environmental media such as soil, groundwater, sediment. [1] Remediation may be required by regulations before development of land revitalization projects.
