"On October 9, 2018 at 2002 CDT the Control Room Emergency Ventilation Air Condition (CREV AC) system was in the process of being returned to service following maintenance.

During the return to service, the end bell on the CREV AC Condenser developed a significant leak requiring isolation.

No work was performed on the CREV AC Condenser during the work window.

"The CREV AC system maintains a habitable control room environment and ensures the operability of components in the control room emergency zone during accident conditions.

"This notification is being made in accordance with 10CFR50.72(b)(3)(v)(D), "Event or Condition That Could Have Prevented Fulfillment of a Safety Function " because the CREV system is a single train system required to mitigate the consequences of an accident."

The NRC Resident Inspector has been notified.
