Säilytunneli

Säilytunneli, which translates to "storage tunnel" in English, refers to an underground excavation designed for the long-term storage of various materials. These tunnels are typically constructed in stable geological formations, such as solid rock, to ensure the integrity and security of their contents. The primary purpose of a säilytunneli is to provide a protected and environmentally controlled space for items that require preservation or safekeeping.

The most common application of säilytunneli technology is for the disposal and storage of low- and intermediate-level radioactive waste. In this context, the tunnels are excavated deep underground to isolate the waste from the biosphere, minimizing the risk of environmental contamination. The geological stability of the rock provides a natural barrier, and the controlled environment within the tunnel prevents water ingress and other factors that could degrade the waste containers.

Beyond radioactive waste, säilytunneli can also be utilized for storing other sensitive materials, such as historical artifacts, valuable documents, or even perishable goods that require consistent cool temperatures. The subsurface location offers protection from surface-level threats like extreme weather, seismic activity, and potential human interference. The design and construction of a säilytunneli involve rigorous planning and engineering to guarantee long-term safety and containment.
