Swedish nuclear reactor back online after fire

A Swedish nuclear reactor fired up again on Monday after being shuttered since November when a transformer caught fire, officials said.

It remains unclear what caused the fire in the transformer, they added, which was located in a different building from the Ringhals 3 reactor. The southwestern Swedish plant was nonetheless closed for security reasons.

“There was a quick and fast fire. That’s one of the big reasons why it’s hard to figure out the exact cause,” said the plant’s spokesman, Anders Jorle.

“Lots of (surrounding) equipment … burned so it’s complicated to know.”

The plant’s closure generated daily losses of 10 million kronor.

Another plant, located north of Stockholm, was closed in July due to a power cut.

Sweden has 10 nuclear reactors, accounting for almost half of the country’s electricity production.
