About this event

The presentation will cover the most recent ground investigations that have been undertaken at the Wylfa Newydd site in Anglesey, north Wales, where Horizon Nuclear Power are planning on building a new build nuclear power station. Since 2010 there have been six significant ground investigations for Wylfa Newydd, where approximately 450 boreholes have been drilled producing around 18,000m of rock core.

The talk will focus on the most recent detailed onshore and offshore investigations which were carried out in 2014 and 2016 respectively.

The presentation will discuss the local geology, the drilling, in situ testing and laboratory testing, together with the logging. It will go on to discuss the site-specific rock mass classification scheme that was developed as part of the geotechnical engineering design for the new build nuclear power station; with discussion on why a site-specific scheme was required, which input parameters were chosen and how the results could be viewed as part of a 3D model that assisted with fault correlation.
