POINT LEPREAU, NB – NB Power says the Point Lepreau nuclear power plant released low levels of water containing a chemical used in its steam generators into the Bay of Fundy.

The utility says the release of hydrazine occurred Sunday from a valve located on the non-nuclear side of the station which contains light water.

NB Power says the release was contained and subsequent testing on Monday showed the chemical had dissipated to levels below detection.

The company says the release was below federally recommended guidelines that determine “impacts on marine life or ecological systems.”


Hydrazine is used to remove the oxygen from the water in the plant’s steam generators protecting the tubes from corrosion.

NB Power says it is continuing to monitor the spill area and has reported the incident to the Canadian Coast Guard and the provincial Environment Department.
