Sellafield Ltd incident report - Building Evacuation – February 25, 2024

A recent trip on a Sellafield substation resulted in a number of buildings within the Low Active Effluent Management Group (LAEMG) area losing power.

As a direct result of the trip, affected buildings in the area were subsequently shut down and building emergencies declared. A roll call took place across the affected building with all personnel accounted for.

After confirming the extent of the power loss, steps were then taken to monitor plants until the power was restored. Once power was restored, monitoring of the affected plants confirmed that there were no issues.
