Project details

Project title

Effect of rock alteration in the chemically disturbed zone (CDZ) of a geological disposal facility (GDF)

Supervisors

Dr Sam Shaw, Antoni Milodowski (British Geological Survey) and Professor Kath Morris (University of Manchester)

Funding

EPSRC through the Nuclear FiRST Doctoral Training Centre (Universities of Sheffield and Manchester)

Project outline

In proposed geological disposal facilities (GDFs) the presence of cementitious engineered barriers in the subsurface will create a chemically disturbed zone (CDZ) at the barrier-rock interface. In this CDZ the chemical composition of groundwater will be altered and its pH raised to 12-13. This will alter the surrounding rock, potentially altering the mobility of nuclear waste in the subsurface. This study aims to investigate the processes of whole rock alteration under CDZ conditions, characterise newly formed minerals and assess the evolution of the rock's chemical and physical transport properties.
