At 1410, a health physics technician noticed smoke in the refueling cavity. Upon investigation, it was noted that a temporary lighting power cord had electrically shorted. The power source was isolated at 1420. The electrical short had ignited a small patch of strippable coating that was applied to the cavity floor for contamination control. The resulting flames were extinguished with demineralized water at 1430. A NUE was declared at 1432 in accordance with licensee procedure EPP-001, Activation and Implementation of Emergency Plan. The area was monitored to ensure that there were no further issues and the NUE was downgraded at 1517. | At 1410, a health physics technician noticed smoke in the refueling cavity.
