Operational concerns: entrainment

The major issue of entrainment from an operational viewpoint is the need to reduce numbers of fish larvae and eggs which are killed. This may lead to constraints on pumping, or the imposition of seasonal outages.

Ongoing monitoring programs: Monitoring of entrainment, fish impingement (including salmon/trout smolts), water quality, and the causes and impacts of CW discharge foaming, at a number of UK power stations.
Entrainment sampling: We have designed and installed a fully automated and computer-controlled entrainment sampler, capable of sampling up to 25 litres/second in hourly units over a 24-hour period. The sampler has been used in evaluating fish egg, larvae and plankton entrainment in a UK nuclear station.
