TRANSPORTING OFF-SITE OF AN INJURED AND POTENTIALLY CONTAMINATED INDIVIDUAL
At 0025 EST, on 02/19/12, a Williams contractor (carpenter) slipped in a puddle of water and fell backwards striking his head and back on the floor of the Turbine building. At 0030 EST, the Shift Manager requested on-site First Responders to report to the scene of the accident. The individual was assessed by Williams safety personnel and SNC First Responders and then packaged for long spine immobilization. At 0101 EST the Shift manager requested Appling County 911 to transport the injured and potentially contaminated individual to Appling County Hospital for evaluation. At 0307 EST, the injured individual was surveyed and found not to be contaminated.
The licensee will be notifying the NRC Resident Inspector.

The licensee is retracting this report based on the following:
"This notification of retraction is being made based on additional information provided by the Health Physics personnel that accompanied the individual to the hospital. Surveys were taken of the individual and clothing and there was no contamination present. Based on the unknown status of individual and clothing upon leaving the site, a notification was initially made as potentially contaminated. Based on the final information obtained at the hospital of no contamination present, the transport of this injured individual to the local hospital does not meet the reporting requirements of 10CFR50.72(b)(3)(xii) and is being retracted. The injured individual was assessed by medical staff and was released back to work without restrictions."
The licensee informed the NRC Resident Inspector. Notified R2DO (Desai).

MANUAL REACTOR SCRAM DURING SHUTDOWN DUE TO LOWERING REACTOR VESSEL WATER LEVEL (RVWL)
"On 2/19/2012 at 1904 hrs [CST] the reactor was manually scrammed from approximately 23% core thermal power due to lowering reactor water level. All control rods fully inserted and all systems actuated and operated as designed. The Reactor Core Isolation Cooling System was manually initiated to assist in level control. No safety relief valves actuated. Reactor level and pressure are currently being controlled within normal bands. Group 2 and 3 RHR Isolation signals were received, however no valve movement occurred since the affected valves are normally closed.
"This event is reportable under 10CFR50.72(b)(2)(iv)(B) for the reactor trip and 50.72(b)(iv)(A) for the manual start of the core isolation cooling system."
The lowest Reactor Vessel Water Level [RVWL] observed was -38 inches WR [Wide Range]. RVWL was restored by placing the "A" Reactor Feed Pump [RFP] in service. The "B" RFP which had been operating was secured for troubleshooting. The Unit was in the process of shutting down for its scheduled Refueling Outage #18.
The NRC Resident Inspector was in the control room at the time of the transient.
