Features, Events, and Processes (FEP) are terms used in the fields of
radioactive waste management,
carbon capture and storage, and
hydraulic fracturing to define relevant scenarios for safety assessment studies. [1] For a radioactive waste repository, features would include the characteristics of the site, such as the type of
soil or
geological formation the repository is to be built on or under. Events would include things that may or will occur in the future, like, e.g.,
glaciations,
droughts,
earthquakes, or formation of
faults. Processes are things that are ongoing, such as the
erosion or
subsidence of the landform where the site is located on, or near.
Several catalogues of FEP's are publicly available, a.o., this one elaborated for the
NEAClay Club dealing with the disposal of radioactive waste in deep
clay formations,[2][3]
and those compiled for deep crystalline rocks (
granite) by
Svensk Kärnbränslehantering AB,
SKB, the Swedish Nuclear Fuel and Waste Management Company.[4][5][6]
