Finding

Title

Licensee-Identified Violation

Description

TS 6.7.1.a requires that written procedures be established and implemented per Regulatory guide 1.33. Procedure OS1036.01 was written pursuant to the above and requires that steam admission valve MS-V-394 be closed with the control switch in the auto position to align the A emergency feedwater (EFW) pump 37A for standby operation during plant operations at power. Contrary to the above, plant operators did not maintain EFW pump 37A operable during plant operation at full power on October 6, 2008, when the control switch for MS-V-394 was inadvertently moved to open during control board activities. The inadvertent operation of MS-V-394 caused steam generator blowdown to isolate. The operators entered the action statement for TS 3.7.1.2, restored EFW pump 37A to the required standby alignment, and restored steam generator blowdown. The finding was more than minor because the incorrect operation of EFW controls resulted in the unplanned inoperability of the A EFW system and impacted steam generator blowdown during plant operations. The finding had very low safety significance because it did not involve a loss of safety function or impact the safety function for a time greater than the allowed outage time in the TS. The inspectors determined that the violation was licensee-identified. The issue was entered into FPLEs CAP as CR 08-13779
