Doctoral thesis: waste heat from nuclear power plants increases eutrophication in the Baltic Sea
Changes to marine flora and fauna at cooling water discharge areas resemble those caused by climate change
Jorma Keskitalo, Helsingin Sanomat Finland’s commercial nuclear reactors in Loviisa and Olkiluoto produce electricity to the national grid to the tune of more than 2,500 megawatts.
This nevertheless equals a mere third of the total energy turned out by the reactors.
Two thirds of the generated energy ends up in the sea as waste heat.
The brackish water from the Baltic Sea that is used to cool down the nuclear power plants warms up in the condensers of the installations by 10-13 degrees Celsius.
