Biological recipient monitoring at the Ringhals nuclear power plant – fish and invasive species

• Fyke net surveys
• Sampling of fish fry and eggs with a bongo net
• Sampling with a modified Isaac Kidd net to document abundance of larger fish fry and adult fish
• Monitoring of invasive species in the recipient area
• Hydrographic observations

The first two reactors at Ringhals nuclear power plant was commissioned in 1974 and the second two began operating in June 1983.

The county administrative board has established a long-term program for monitoring the biological effects of the cooling water with fyke nets in two areas that are differently affected by the cooling water and also in a reference area.

Staff from Institute of Coastal Research at SLU Aqua also collects biological material from both land and sea for a radio ecology monitoring program under the responsibility of the Swedish Radiation Safety Authority (SSM).

The results from the biological recipient monitoring are reported annually. Every five years the results are reported in a more extensive and profound way.
