Dedication of emergency diesel generators` control air subsystem
In the spring of 1993, the need to upgrade Seabrook Station`s emergency diesel generators` (EDGs`) control air system from nonsafety related to safety related was identified. This need was identified as a result of questions raised by the US Nuclear Regulatory Commission, which was conducting an Electrical Distribution Safety Functional Inspection at Seabrook at that time. The specific reason for the reassignment of safety classification was recognition that failure of the control air supply to the EDGs` jacket cooling water temperature control valves could cause overcooling of the EDGs, which potentially could result in EDG failure during long-term operation. This paper addresses how the installed control air system was upgraded to safety related using Seabrook`s Commercial Grade Dedication (CGD) Program and how, by using the dedication skills obtained over the past few years, it was done at minimal cost.
