TOXIC GARDENING

​

The act of gardening is simultaneously a form of destruction and creation. 'Toxic Gardening' encases highly radioactive ecosystems, eradicating it in the most extreme manor to protect the surrounding environment. Hotspots range from the size of a small structure to an entire forest, this is a consequence of the radiations dispersal via wind and water, as well as a lack of recording during the Soviet’s decontamination process.

​

CONTAINMENT

​

The Hotspot is bulldozed and compacted. Then, using the same principles of other Near-Surface Nuclear Disposal Facilities, the radiation is contained using a series of protective layers; including intrusion barriers, membranes and clay linings. The designs resists erosion, which would risk exposing the geology.

​

Burying the waste above ground height creates a permanent change to the landscape's topography; creating a signal for future generation to the location of the radiation. 

​

LONG-TERM ADVANTAGES - PROTECTION/CREATION

​

To compensate for the loss of the cooling pond's ecosystem, the top surface of the mound will be used to create a shallow wetland. Using water pumped from the river and drains back in when the water reaches above 50cms. A mixture of local submergent, emergent and floating vegetation will be introduced to encourage a rich biodiversity. 

KEY WORDS - Containment, Ecological Stimulation

ISSUE - Radioactive Hotspots

Key - Site Location (Highlighted White Area)

Note: The Exclusion Zone has a unknown number of other Hotspots due to a lack of fully radioactive mappings. Therefore other than the known Hotspots in close proximity to the Nuclear Reactor there could be any number more, ranging in scale from micro to macro.
