Koodankulam Desalination: Looming Calamity for Gulf of Mannar
At the not yet commissioned Koodankulam nuclear power plants (KKNPP) there looms a serious threat from a chain reaction in the Gulf of Mannar that would happen even if a nuclear catastrophe never happened. That threat is a biological chain reaction, a biodiversity collapse.
For each nuclear power unit, four desalination (desal) units are required to supply the water. These behemoth wet-vacs suck in enormous quantities of seawater. However that is not all that is vacuumed into their voracious maws (maw = the opening into something felt to be insatiable). The essential base, the heart of the developmental stages of marine life and food chain, microscopic to tiny sea flora and fauna, including phytoplankton, zooplankton, fish eggs and larvae of myriad sea creatures, will be impinged, entrained and killed in large quantities in the desalination units.
Impingement
occurs when organisms are pulled into an intake pipe and trapped
against a fish screencovering
the intake, causing injury or death. Entrainment occurs when small
organisms pass through the fish screen and are actually taken into
the intake pipes. ...Continued
