Aux Feed Pump mini-recirc issue It has been determined that the AFP mini recirc flow orifice is susceptible to plugging if Service Water was used as the suction source to the pump and all running pumps could plug at the same time. Also it cannot be determined that the same would not happen if the CSTs were the suction source. For the AFPs to be considered operable the mini recirc cannot be relied on to provide minimum flow. Anytime the pump is running a minimum forward flow must be maintained. If this flow cannot be maintained then the pump shall be secured until the flow requirements can again be reestablished. Temporary Information tags, containing the minimum flow requirements, have been placed on the boards where aux feed pump flow is read Follow up short term actions also include changing all pertinent procedures to address this issue
