Shutdown
The reactor operated successfully until 1992 when an unplanned power spike caused an automatic shutdown. During the shut down an investigation revealed a tritium contaminated cooling water leak at which time the department of energy had the fuel rods removed and placed the reactor in permanent safe shut down mode and scheduled for decontamination and decommissioning. The OWR was fully decommissioned in 1994 and demolished in 2003. The demolition project was completed under budget and ahead of schedule.
