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.

Related phenomena; seismicity
Lightning strikes on or near nuclear and other types of power stations have a wide range of potential impacts. Overvoltage protection devices would be operated, and transformers can be damaged. These impacts can disrupt the supply of stable offsite power required by the power station. Electrical and electronic control equipment could also be affected. This volume describes the phenomenon, its detetion and modelling, risks and mitigations.
