GNF-A Written Follow-up Report - Fire System Impairment

Dear Sir or Madam:
In accordance with 10 CFR 70.74(b), Global Nuclear Fuel-Americas, LLC (GNF-A) hereby submits a written follow-up report for Event Notification 54297 which was provided to NRC on September 27, 2019 (Reference 2).
Event 54297 As discussed in the initial event report, GNF-A reported a fire system impairment to the New Hanover County (NHC) Deputy Fire Marshall. Consistent with 10 CFR 70, Appendix A(c), a concurrent report was provided to NRC and is included as Attachment 1 to this letter.
Additional information is provided as follows:
Event Details and Safety Significance At 1939 (EDT) on September 26, 2019, the New Hanover County Deputy Fire Marshall was notified per State code requirements that a portion of the fire alarm system in the Fuel Manufacturing Operation (FMO) building was not operating as intended. Compensatory measures were enacted. Because the New Hanover County Deputy Fire Marshall was notified, a concurrent notification to the NRC Operations Center was made at 1339 on September 27, 2019 per 1 O CFR 70, Appendix A(c). There was no degradation of an item relied on for safety (IROFS) or failure to meet performance requirements.
Probable Cause of Event An investigation determined that several of the alarm system terminal strips had corroded connectors that would not allow the signal from the alarm supervisory system to pass to other areas.
US NRC M190206 November 26, 2019 Page2 Short Term Corrective Action
- 1) The affected terminal connectors were replaced, and the system was restored to service at approximately 1723 EDT on September 27th, 2019. The NHC Deputy Fire Marshal was notified of the return to service at 1739.
Longer Term Corrective Action
- 1) A biennial preventative maintenance routine has been developed to periodically check alarm system terminal connectors for corrosion.
Completed October 8, 2019 If you have any questions regarding this matter, please contact me at (910) 819-5950.
Sincerely, i~f!2~
