The Natural Hazards Review project will develop a framework and best practice approach to characterise natural hazards and seek to improve methodologies where current approaches are inefficient. This is to improve energy system infrastructure design and the project is intended to share knowledge of natural hazards across sectors. The project will be completed in three stages. Phase one will focus on a gap analysis. Phase two will look at developing a series of improved methodologies from the gaps identified in phase one, and phase three will demonstrate how to apply these methodologies. Finally, phase 3 will develop a “how to” guide for use by project engineers.
This case study illustrates the appropriate use of the derived methodology for Trawsfynydd, Wales. Trawsfynydd is located in North Wales and is the site of a nuclear energy plant (currently being decommissioned). The site was chosen as representative of an inland site. This document introduces the location and a demonstration of the hazard characterisation methodologies for:
Seismic, geological and volcanic hazards including ash deposition
