Nirex Rock Cores And Core Samples From Deep Boreholes.

During the period from 1989 to 1997, Nirex undertook extensive geological investigations at sites near Sellafield, in Cumbria, and Dounreay, in Caithness, to examine whether or not they were suitable locations for a deep repository for radioactive waste. At Sellafield, thirty deep boreholes, and a further thirty-five shallow boreholes, were drilled. The majority of the deep boreholes were drilled to obtain continuous core and some 18.7km of rock core arose from the investigations. Two deep boreholes were drilled at Dounreay, totalling 2,286 metres of drilling. Again, much of the drilling was to obtain continuous core. In most of the boreholes a suite of data acquisition techniques were used, including: continuous coring, geophysical wireline logging, hydraulic testing, sampling and analysis of groundwaters. Mineralogical data were acquired by detailed core observation, petrographic analysis, fluid inclusion analysis and stable and radiogenic isotope studies. Testing on samples from the rock cores was undertaken to determine petrological, mineralogical, hydrogeological, geophysical and geotechnical parameters. The ownership of NIREX (Nuclear Industry Radioactive Waste Executive) was transferred from the nuclear industry to the UK Government departments DEFRA and DTI in April 2005, and then to the UK's Nuclear Decommissioning Authority (NDA) in November 2006.

Access constraints: Other restrictions

Other constraints: NIREX granted the British Geological Survey a licence to use and to allow third parties to use the data for bona fide academic or educational purposes. Commercial organisations wishing to use the data should, in the first place, apply to The Nuclear Decommissioning Authority (NDA) for access to the archives, this can be done through BGS, contact Richard Shaw. A fee may be payable to the British Geological Survey for access to the data.

Supplemental Information: Nearly all of cores and samples from the Nirex deep boreholes are held by the BGS. All cores were re-packaged from their original core boxes into cardboard boxes for transfer to BGS. All original drillers depth identifers, core run numbers etc have been maintained.
