Operators at the Susquehanna nuclear power plant in Pennsylvania recently performed a planned and controlled shutdown of the Unit 1 reactor to investigate the source of a foundation leak inside the containment structure around the reactor. The Unit 2 reactor is still operating at full power while the leak detection strategy is put into place.
"The leak does not affect the safety of the plant or the public," said Timothy Rausch, PPL's chief nuclear officer. "We made the prudent decision to shut down the unit while the leak is small and will return it to service after we make the needed repairs."
According to Fox Business, a nuclear reactor in Sweden was also shut down after an oil leak was discovered, causing a problem with a transformer. The leak led to the automatic shutdown of a turbine and stopped the reactor until repairs could be completed. Apparently a technical error led to the oil leak in the reactor.
