Abstract
This study aims to investigate the mechanisms of jellyfish and seaweed ingress that could cause problems to the smooth operations of power plants located on coastline when their cooling water inlets are exposed to these kinds of attacks. Ingress events may lead to clogging of the filters and result in a shutdown of the power plant. Jellyfish are presenting a particular problem with an increase in populations observed globally due to warmer coastal waters, over-fishing and pollution. The ingress mechanisms and conditions are still poorly understood and difficult to predict numerically. The ingress mechanisms are being investigated through numerical modelling of hydrodynamics around the east coast of Scotland near to Dunbar. Torness power station, located in the study area, has been subjected to jellyfish ingress resulting in a controlled temporary shutdown of the two power station units, at a considerable cost to the operators. This project aims to provide an understanding of ingress mechanisms by numerical modelling of the hydrodynamics and the assessment of the conditions that govern the transport of growth of the marine life.
Highlights
Validation of the hydrodynamic model concerning the coastal area around the power station
How can we predict the ingress mechanisms in the future and prevent temporary shutdowns ?
The Torness nuclear power station, located along the Eastern coast of Scotland, over the last years several has been subject to partial or complete shutdowns caused by the ingress of different types of drifters, algae, seaweed and jellyfish, into the water intake
Summary
The Torness nuclear power station, located along the Eastern coast of Scotland, over the last years several has been subject to partial or complete shutdowns caused by the ingress of different types of drifters, algae, seaweed and jellyfish, into the water intake. Validation of the hydrodynamic model concerning the coastal area around the power station. How can we predict the ingress mechanisms in the future and prevent temporary shutdowns ? These ingress events resulted in the clogging of the filtering drums, which filter the seawater, and disrupted the cooling water supply for the power station.
