Finding

Title

Failure to Provide Adequate Lubrication for Drywell Fan Coil Units

Description

The inspectors reviewed a self-revealed finding for the licensees failure to implement Work Order 5060136 during maintenance on the drywell fan coil units. Specifically, on October 26, 2016, during bearing replacement work on drywell fan coil, unit D, maintenance personnel failed to properly reinstall auto-lubricator injection connectors after removing the interferences per the work order instructions. This error resulted in the failure of drywell fan coil, unit D, due to inadequate bearing lubrication, and ultimately led to a downpower and reactor shutdown.
