Attachment B OPERATIONS NARRATIVE Cooper Nuclear Station September 1982 The plant operated the month of September with only one unscheduled shutdown. On September 4, 1982, an electronic component in the "A" feedwater pump control system failed causing the "A" FW loop flow to drop to nearly zero flow. Reactor water level decreased to the trip level and the reactor scrammed. Although the "B" FW automatically increased its flow to compensate for the loss of the "A" FW loop flow, it was insufficient to prevent the reactor scram. The failed component in the FW control system was replaced and the plant was returned to operation.
