The circumstances surrounding this LER are documented in Inspection Report 05000266/2018004; 05000301/2018004, Results Section 1R20, Outage Activities, (ADAMS No. ML19022A242). This LER is closed.

INSPECTION RESULTS

Observation 71152 The inspectors reviewed condition reports associated with the licensees transition to NFPA 805, Performance-Based Standard for Fire Protection for Light Water Reactor Electric Generating Plants. Specifically, the inspectors reviewed the licensees identification and resolution of various problems that had been identified after the licensee implemented NFPA 805 in February 2017. Examples of documented problems included required procedure changes that were not implemented prior to NFPA 805 transition, incorrect fire barrier categorization, and control cables incorrectly categorized as instrument cables.

Generally, the inspectors found that the licensees corrective actions were appropriate to correct the issues once they were identified; however, the inspectors determined gaps existed in the licensees NFPA 805 transition process and many of the issue could have been identified prior to NFPA 805 implementation.

EXIT MEETINGS AND DEBRIEFS

The inspectors verified no proprietary information was retained or documented in this report.

• On April 3, 2019, the inspector presented the quarterly integrated inspection results to Mr. R. Craven and other members of the licensee staff.
