Vermont Yankee nuclear power plant in Vernon, VT, is in the process of restarting after officials detected a leak Sunday.
With the reactor starting up, Vermont Yankee official expect the plant to reconnect to the grid on Wednesday or Thursday.
The plant shut down Sunday after workers spotted a leak of radioactive water during routine surveillance.
Technicians found the leak came from a welded-over section of pipe in the feed water system, a closed loop that feeds water to the reactor.
Technicians fixed a leaking plug on the feedwater discharge pipe that caused the shutdown of the plant Sunday night, a spokesman said.
The plug, leaking about 60 drops of radioactive water a minute, was part of a port used during the initial construction of the plant in 1972 and performed radiography on the pipe and check on the integrity of the welds, Vermont Yankee spokesman said.
In January 2009, officials found a similar leak in a smaller pipe in the feedwater system.
While the plant was in cold shutdown, plant personnel also made repairs to the drain line of a High-Pressure Coolant Injection system drain line that had a pinhole leak discovered in late October, the spokesman said.
The U.S. Nuclear Regulatory Commission said the leak posed no danger to the public.
