"Duke Energy McGuire Nuclear Station (McGuire) has determined there is evidence of a departure from technical requirements, a Deviation, associated with Joslyn Clark overload heater element Part Number (PIN) 2455. This part was procured in accordance with the Duke Energy Commercial Grade Program (CGP) and dedicated for use in safety related applications. Three of 18 overload heater elements, purchased as a lot, had insufficient top weld material. One failed in-service during a post maintenance test, the second and third failed during a visual and mechanical inspection. An extent of condition review inspected over 500 similar J~slyn Clark overload heater elements. No other inventory was found with a top weld issue.
"These overload heater elements are used in motor starters for the Emergency Diesel Generator (EDG) ventilation fans. This condition was discovered during post maintenance testing of the 2A EOG on July 27, 2016. None of the suspect overload heater elements were installed in Operable EOG ventilation fan motor starters. The dedicated overload heater elements, from this lot, were not transferred or sold to any third party customers. Specialty Product Technologies, manufacturer of the Joslyn Clark overload heater elements, has been notified of the deviation and is investigating their welding process.
"The Evaluation of the deviation determined that a Substantial Safety Hazard would have been created if the overload heater elements were installed and left uncorrected.
