Title	Penetration Room Filtration Boundary Inoperable
Event Description	This notification is being made as required by 10 CFR 50.72(b)(3)(v) due to both trains of Penetration Room Filtration [PRF] being inoperable due to an inoperable PRF Boundary. At 0920 [CDT] on 6/2/2017, a gap was discovered between an electrical penetration room ceiling and the containment wall where seismic gap material was noted to be missing. The gap was subsequently closed and PRF testing completed sat. The condition was exited at 1345 [CDT]. The licensee notified the NRC Resident Inspector. * * RETRACTION ON 7/25/17 AT 1725 EDT FROM MATT STANLEY TO DONG PARK * * * On 6/2/17 at 1707 CDT Farley Nuclear Plant notified the NRC Operations Center of an entry into Technical Specification 3.7.12 Condition B for Unit 1 loss of two trains of Penetration Room Filtration (PRF). At 0920 [CDT] on 6/2/2017, a gap had been discovered between an electrical penetration and containment where seismic gap material was noted to be missing. The report was made pursuant to 10 CFR 50.72(b)(3)(v) under Event Notification 52785. Upon further engineering review and satisfactory testing to support operability, Farley has determined that the configuration did not meet the criteria for a condition that could have prevented fulfillment of a safety function, and is retracting the notification. The NRC Resident Inspector has been notified. Notified R2DO (Blamey).
