Palisades Steam Leak Radioactive

The steam that leaked from a drain valve at Palisades Nuclear Power Plant near South Haven, MI, Sunday contained low levels of radiation.

Workers were able to contain the leak in an auxiliary building and it did not impact other equipment. The Nuclear Regulatory Commission (NRC) has no immediate safety concerns with the issue, said Viktoria Mitlyng, NRC’s senior public affairs officer in Illinois.

“The steam leak contained very low levels of tritium at concentrations far below the regulatory limit,” Mitlyng said. “The steam leak condensed, remained in the auxiliary building and will be treated as radioactive liquid waste. The leak stopped as pressure was reduced in the main steam system during plant cool down.”

The plant will remain shut down while workers make the repairs. New Orleans-based Entergy Corp. owns the plant.

In September 2011, very low levels of the radioactive isotope tritium released into the atmosphere after a breaker fault in the plant’s electrical system caused a shutdown. The tritium from that release dissipated in the atmosphere.
