LEPREAU, N.B. - Radioactive heavy water has spilled at the Point Lepreau nuclear power plant in New Brunswick.
Kathleen Duguay, a spokeswoman for NB Power, says the spill occurred Tuesday evening in the reactor building.
Duguay didn't know the exact amount of water spilled, but she said it was "minute."
She says no one was hurt.
The spill occurred as the reactor's moderator system was being filled with heavy water as part of NB Power's plan to restart the generating station, which has been undergoing a lengthy and expensive refit.
Duguay says the spill was detected by radiation monitoring equipment and the reactor was evacuated immediately.
Duguay says workers in the area were wearing protective suits at the time and were not exposed.
She says the spill was cleaned up soon afterwards.
The cause of the accident wasn't known.
