Oak Ridge reactor shut down after relay line failure

OAK RIDGE, Tenn. (AP) - Operators have shut down the High Flux Isotope Reactor at the Oak Ridge National Laboratory after an electrical relay line failed.

The Knoxville News Sentinel reported on its Web site Monday night that the problem was detected at about 9 p.m. Saturday when control room operators got a warning light indicating a relay failure. A subsequent series of checks confirmed the problem.

The electrical line was replaced over the weekend, and restart testing was being done Monday.

Kelly Beierschmitt, director of nuclear operations at ORNL, said the electrical line was at least 20 years old and this probably caused the failure.

The research reactor was built in the 1960s.
