Jellyfish force nuclear plant shutdown in Sweden

It wasn’t a tsunami but it had the same effect: A huge cluster of jellyfish forced one of the world’s largest nuclear reactors to shut down — a phenomenon that marine biologists say could become more common.

Operators of the Oskarshamn nuclear plant in southeastern Sweden had to scramble reactor number three on Sunday after tonnes of jellyfish clogged the pipes that bring in cool water to the plant’s turbines.

By Tuesday, the pipes had been cleaned of the jellyfish and engineers were preparing to restart the reactor, which at 1,400 megawatts of output is the largest boiling-water reactor in the world, said Anders Osterberg, a spokesman for OKG, the plant operator.

All three Oskharshamn reactors are boiling-water types, the same technology at Japan’s Fukushima Daiichi plant that suffered a catastrophic failure in 2011 after a tsunami breached the facility’s walls and flooded its equipment.

Jellyfish are not a new problem for nuclear power plants. Last year the California-based Diablo Canyon facility had to shut its reactor two after gobs of sea salp — a gelatinous, jellyfish-like organism — clogged intake pipes. In 2005, the first unit at Oskarshamn was temporarily turned off due to a sudden jellyfish influx.
