Abstract

Recent regulatory Best Available Technology (BAT) guidance in England and Wales supports the use of fish recovery and return (FRR) systems at thermal power station cooling water intakes as part of fish protection measures. New guidance on eel (Anguilla anguilla) screening to meet the latest regulatory requirements also proposes possible modification of existing travelling band and cup screens at raw-water pumping stations for FRR as a means of eel screening. While FRR technology has been available for many years, its use and operational experience are still quite limited, and there are few existing examples that would meet current BAT guidance. Operators trying to introduce FRR are having to push the boundaries of existing knowledge to meet BAT standards. Some of the issues are explored and solutions discussed. Keywords: band screen, drum screen, power station, fish recovery and return, FRR, best practice.
