Wylfa Power Station - rock mass classification and engineering seismology, London

About this event

Extensive ground investigations have taken place at the Wylfa Newydd site in Anglesey, north Wales, where Horizon Nuclear Power are planning a new build nuclear power station. Since 2010 there have been six significant ground investigations, with approximately 450 boreholes being drilled that produced around 18,000m of rock core.

The first part of the presentation will focus on the most recent detailed onshore and offshore investigations carried out in 2014 and 2016 respectively, discussing the local geology, drilling, logging and testing, including how and why a site-specific rock mass classification scheme was developed as part of the geotechnical engineering design.

This will be followed by a discussion concentrating on the engineering seismology aspects of the site and discuss the Probabilistic Site Hazard Assessment involved for a nuclear new build site.
