Abstract/Summary

The British Geological Survey was commissioned by United Kingdom Nirex Limited (‘Nirex’) to manage the Off-Site Core Characterisation Programme (OSCCP) as part of its investigations into the Sellafield and Dounreay areas as possible sites for a deep repository for solid low and intermediate level radioactive waste. The OSCCP provides rock property data for geological interpretation, safety assessment, and design studies associated with the repository development. A broad range of geoscientific tests and analyses were performed on samples of core, and on pore-waters extracted from core, from Nirex’s deep drilling programme. In addition, the geological and geotechnical properties of the core were comprehensively logged. Interactive matching of core features and geophysical images allows the core to be orientated. The OSCCP draws on the expertise of geoscientists from many disciplines including stratigraphy, structural geology, mineralogy, petrology, sedimentology, biostratigraphy, hydrogeology, geochemistry, engineering geology, geotechnics, and geophysics. The broad scope of the programme was met by establishing liaison between a number of scientific consulting organisations. Work carried out under the OSCCP was controlled by Quality Assurance standards. A sample tracking database allows each sample to be identified along with its current location, sub-samples, and the tests to which it has been subjected. The Nirex core characterisation programme for the Sellafield and Dounreay sites was designed for a hard, fractured rock site. The methodologies used in the Nirex Programme are not necessarily directly applicable or relevant to site investigation in a soft rock/clay site such as Horonobe.
