"This telephone report is being made in accordance with 10 CFR 50.72(b)(3)(v) as a loss of safety function for a single train safety system. On August 23, 2011 at 1530 CDT, the clevis pin that connects the valve with the air operator was found not fully inserted on the Control Room HVAC Emergency Bypass System Inlet Valve, HV-AO-271 AV. This valve is normally closed and opens in response to a Group 6 isolation signal to align the Control Room Emergency Filtration System) (CREFS) to outside air. A retaining clip at one end of the pin was found to be missing, allowing the pin to partially back out of the clevis. The pin was found engaged with half of the clevis. This condition resulted in declaring CREFS inoperable at 15:30 CDT, and CNS entered LCO 3.7.4 Condition A which requires the CREF system to be restored to OPERABLE status in 7 days. The cause of the displaced clevis pin is under investigation."
The licensee has notified the NRC Resident Inspector.

"This notification is being made to retract Event Notification EN# 47195 which reported a loss of safety function for a single train safety system due to the unplanned inoperability of the Control Room Emergency Filtration System (CREFS). CREFS was declared inoperable on August 23, 2011 per LCO 3.7.4 due to finding a clevis pin not fully inserted on the valve operator for the Control Room HVAC Emergency Bypass System Inlet Valve IIV-AOV-271AV. This normally closed valve opens on a Primary Containment Group 6 Isolation signal to align CREFS to outside air. The retaining clip at one end of the pin was found missing which allowed the pin to partially back out of the clevis.
"Cooper Nuclear Station (CNS) recently completed its trouble shooting of the as-found condition of the pin and a subsequent evaluation of its ability to withstand seismic loading. CNS determined that CREFS would have been able to fulfill its safety function. The clevis pin was shown via testing to remain engaged when the valve was stroked. The seismic evaluation showed that the maximum seismic force is less than one-tenth of the estimated force required to remove the pin, and consequently it is not credible that the pin would have become disengaged in a seismic event. CREFS did not lose the ability to perform its safety function."
The NRC Resident Inspector has been notified.

| Event Text AGREEMENT STATE REPORT INVOLVING A LESS THAN PRESCRIBED DOSE ADMINISTRATION
The following information was received from the State of Texas via email:
"On September 13, 2011, the Agency was notified by the licensee that it had determined that a medical event had occurred at its facility. The licensee reported that on Friday, September 9, 2011, a patient had undergone a therapy procedure at approximately 3:00 p.m. which involved insertion of Yttrium-90 TheraSpheres into the liver. The patient's prescribed dose was to be 80 gray. Following the procedure, the technician took measurements, as part of the standard operating procedures, of the vial and other items associated with the treatment. The technician found that the dose rate was higher than would be expected if all of the contents of the vial had been delivered. The technician notified the medical physicist and they discussed the measurements. At approximately 6:00 p.m. they determined that an underdose had most likely occurred, but they were not yet sure it was a medical event. On Monday, September 12th, evaluation and measurements were conducted on the vial and dose calculations were completed. On Monday afternoon, it was determined that the patient had received a dose of 49 gray (22.3 millicuries administered), which is 39% less than the prescribed dose of 80 gray (37 millicuries). A meeting was arranged with the facility's Radiation Safety Officer on Tuesday, September 13th, at which time he was advised of the findings. Initial investigation by the licensee indicated some type of failure of the septum on the TheraSphere vial had occurred. The licensee will complete their investigation and submit a written report. An update to this report will be provided when new information is received."

| Event Text AGREEMENT STATE REPORT - FAILURE OF RADIOGRAPHY CAMERA LOCKING MECHANISM
The following information was received via e-mail:
"On September 7, 2011, the licensee discovered a failure of the locking mechanism of a QSA 880-Delta radiography exposure device. This is a 30-day notification event. Device: 880 Delta. S/N: D7822.
"During the installation of the 880 camera, it was discovered that the locking mechanism would not return to the 'Stored / Locked' position. While investigating the malfunction, it was determined that possibly one of the springs in the locking mechanism was bad. The manufacturer (QSA Global / Sentinel) was called and the malfunction was explained and it was requested that the camera be sent back for further investigation and correction of the malfunction.
"This camera did not have a radioactive source in it or attached to the drive cable at the time of the malfunction discovery. This is a brand new 880 Delta camera and has not had a radioactive source in it. The source to be installed in the camera is being stored in a 650L changer, serial number 2168 and secured in [the licensee's] radiography booth.
"The RSO was the only person in the radiography booth when the malfunction was discovered and no potential exposure occurred.
"Updates will be provided through NMED.
