The Point Lepreau Nuclear Generating Station has reopened after a leak of a radioactive isotope earlier this month.
A release from N.B. Power says the station returned to operation on Sept. 26
The utility first became aware of a problem inside its reactor building on Sept. 10, when its monitoring system identified elevated levels of tritium.
Tritium is a radioactive isotope that occurs in the heavy water used to transfer heat from nuclear reactors.
Lepreau was shut down on Sept. 11, and a heavy water leak from a 3/8th-inch instrumentation line was confirmed on Sept. 14.
An N.B. Power fact sheet says the instrumentation line was chafing against structural steel, causing the leak of about 200 litres of heavy water.
