Predicting extreme weather and sea level for nuclear power plant safety – PREDICT

The safety management over the life cycle of a nuclear power plant requires probability estimates of exceptional weather and sea level conditions in the current and future climate. The main objective of PREDICT is to develop and maintain research expertise and methods needed for assessing probabilities of occurrence of safety-relevant single and compound extreme weather and marine events, both in the range of 0–15 days ahead and in decadal time scales of recent past and future climatic changes. The expected results include improved probability estimates for intense coastal snowfall, coastal flooding risks and compounding extreme events, such as heavy rain and high sea level.

Figure: Simultaneously occurring two or more external events, such as high wind speed and high sea level, may cause more severe consequences than single incidents alone.
