The disposal of waste, including nuclear waste (from the nuclear power industry and other nuclear applications) and carbon dioxide (to reduce carbon dioxide emissions and associated greenhouse warming) constitutes one of the major environmental technical challenges of the 21st Century. One way to address this challenge is to construct subsurface geological repositories in which this waste can be stored over long-term (>millennia) timescales. In this network (GeoRepNet), we are developing a three-year collaborative network to investigate and prioritise the major challenges involved in the design, construction and maintenance of geological repositories.

GeoRepNet is funded by the Science and Technology Facilities Council (STFC).

The network is comprised by six workpackages that address the geophysical, geochemical and biological challenges of establishing and operating geological repositories and investigate methods of monitoring geological repositories. The technical focus of the network, addressed by a dedicated workpackage, examines the cross-transfer of technology from the space and astronomical communities into geological repository monitoring, for example miniaturised in-situ instruments designed for planetary exploration and spectroscopic methods of monitoring repository atmospheres to detect leakage of wastes.

Our overall aim is to advance the identification, prioritisation and provision of solutions to establishing and maintaining geological repositories.
