Generalised methodology FEPS

Example – waste repository

Features – waste, surface water, ground water, soil

types, rock types, atmosphere, plants, humans, engineered barriers

Events – earthquake, flood, fire, intrusion Processes – leaching, groundwater flow, surface

flow, erosion, resuspension, transfer to plants, irrigation

Characteristic matrix – waste repository – uncovered waste

Example – Gela

Features – waste, surface water, ground water, soil types,

rock types, atmosphere, plants, humans, engineered barriers

Events – earthquake, flood, fire, intrusion Processes – leaching, groundwater flow, surface flow,

erosion, resuspension, transfer to plants, irrigation

Specific features:

Retaining wall around the site – penetrates about 3 m into the

underlying clay

Leachate is returned from the downstream sampling wells to the top

• f the stack

Kevala - existing situation

(563.240m2)

Inactive site

Application to Kevala

Single source compartment needs to be expanded Have to allow for transfers (via water) between

source compartments

Transfer of fluid to and from the ocean

Example – stack discharge

Features – stack, stack filters, atmosphere, soil,

plants, humans,...

Events – filter breakdown Processes – advection, convection, diffusion, dry

deposition, wet deposition, leaching,.....
