OSLO, July 30 (Reuters) -
* Sweden’s Ringhals-2 nuclear reactor has been taken offline due to high water temperatures, operator Vattenfall said on Monday
* Ongoing warm weather in Sweden means that seawater has reached 25 degrees Celsius over the the last few days, Vattenfall said in a statement
* To maintain cooling capacity in the Ringhals nuclear plant, seawater is used to cool different systems and components
* “When the water gets warmer, its cooling effect reduces and in order to maintain the cooling capacity needed for different systems, we need to now take Ringhals 2 out of operation,” said Sven-Anders Andersson, production manager at Ringhals.
* The 865-megawatt (MW) pressurized water reactor is one of the four reactors at the plant. Ringhals-3 and 4 reactors are still online. Ringhals-1 is due to undergo annual planned maintenance. (Reporting by Lefteris Karagiannopoulos; writing by Nina Chestney)
