A nuclear reactor at Brown's Ferry in Alabama had to be shut down because the river water used for cooling was too hot! This is the first time this has happened in the USA.
With daytime temperatures the hottest they have been in at least 20 years, the TVA is being forced to buy energy on the open market thus raising prices for its customers.
