| Event Text MEDICAL EVENT INVOLVING A DOSE THAT IS DIFFERENT THAN PRESCRIBED
The patient was undergoing brachytherapy treatment of the prostate. After 6 seeds were implanted, the procedure was aborted because of concerns in placing additional needles into the patient. The prescribed dose was 145 Gy. However, only 6 of 88 prescribed seeds were implanted. Each seed total activity is 0.288 mCi of I-125.
Family members were notified of the aborted procedure.
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.
* * * UPDATE FROM ROBERT TURCO TO JOHN KNOKE AT 1643 EDT ON 5/22/09 * * *
This event is being retracted because the physician made a choice to terminate the brachytherapy treatment of the prostate to the patient. The physician then rewrote the procedure to the patient to limit the prescribed number of seeds to 6. Having 6 seeds implanted into the patient the prescribed dose was now met under the new directive.

| Event Text AGREEMENT STATE REPORT - SHUTTER ON GAUGE INOPERATIVE
"On March 21, 2009, at 1050 AM, the Agency [Texas Department of Health] received a report from the licensee that while performing the biannual test on a Ronan Engineering nuclear gauge, model # SA-1, containing an original activity of 100 millicuries (calculated current activity of 75 millicuries) of Cesium (Cs) - 137, the shutter failed to close. The gauge is installed on the side of a vessel approximately 50 feet above ground and is used for level detection. A dose rate measurement taken at the gauge indicated 0.03 millirem per hour, and poses no risk of radiation exposure to their workers. The manufacturer has been contacted to provide corrective maintenance on the shutter."

"At approximately 1904 on 05/27/09, Sequoyah Unit 2 received an Automatic Reactor trip on Power Range High Neutron Rate Reactor Trip. The automatic trip occurred during severe weather and lightning onsite. ESF functions initiated as designed including Aux Feed Water auto-start and automatic Feedwater isolation. All control rods fully inserted. The plant is currently being maintained in Mode 3 at approximately 547 degrees F 2235 PSIG. Decay heat is being removed by the Auxiliary Feedwater system and Steam Dump valves.
"The cause of the Power Range Neutron Flux High Rate Reactor Trip is not known at this time and investigation is ongoing.
"Unit 1 remains at 100% power".
No relief or safety valves lifted. The electrical lineup is normal and the 2B Diesel Generator is tagged out for maintenance.
