The Swedish nuclear regulator has recommended that the operators of four reactors that will shut earlier than planned - Oskarshamn units 1 and 2 and Ringhals 1 and 2 - should pay higher waste fees to ensure the country's nuclear waste fund is sufficient.
In southeastern Sweden, workers were forced to close one of the reactors at the Oskarshamn nudear power plant which supplies 10% of the country's power after a massive swarm of moon jellyfish dogged the cold water intake pipes that help regulate the reactor's temperature.
