"In preparation for quarterly valve testing, the High Pressure Coolant Injection system was declared inoperable and the technical specification required actions were implemented. The system was available for on-line risk. During the testing, the inboard steam isolation valve was stroked closed and reopened and operated properly. The valve was reclosed to continue with valve testing. When an attempt was made to reopen the inboard isolation valve, the valve failed to indicate full open.
"The system remained inoperable due to the valve malfunction. Therefore, the condition is being reported in accordance with 10 CFR 50.72 (b)(3)(v)(D) as a condition that at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to mitigate the consequences of an accident.
"Maintenance activities are currently in progress to restore the system to the operable status."
The licensee entered a 14-day Limiting Condition of Operation per Technical Specification 3.5.1.
The licensee notified the NRC Resident Inspector.

"On September 15, 2010, the NRC Operation Center was notified of Event Number 46253 that described a failure of the High Pressure Coolant Injection (HPCI) system inboard steam isolation valve to fully reopen using the Main Control Room (MCR) control switch.
"At the time, it was not readily apparent that the system was capable of performing its intended safety function. Therefore, the condition was reported in accordance with 10 CFR 50.72 (b)(3)(v)(D) as a condition that at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to mitigate the consequences of an accident.
"Troubleshooting identified that a contact in the control switch circuit had malfunctioned. This contact is bypassed during an initiation signal. Therefore the valve would have opened fully in the event the HPCI system received an initiation signal.
"In light of these findings, the HPCI function was not impaired as a result of the contact malfunction and would have been capable of performing its safety function. Therefore, the notification associated with Event Number 46253 is being retracted."
The NRC Resident Inspector has been notified.
R3DO (Dave Passehl) has been notified. |

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE REPORT - UNPLANNED EXPLOSION DAMAGING MIXTURE OF 400 MILLICURIES OF CARBON 14
This information was emailed from the state as follows:
During a routine health and safety inspection, the [state] inspector learned that an explosion had occurred at the facility on December 3, 2009. An Authorized User was quenching a mixture containing 400 milliCuries of Carbon-14 at the time of the explosion. The individual showered and was taken to the emergency room. The individual had several bioassays done prior to returning to work. The licensee decontaminated the area of concern within the lab. Iowa Item Number: IA100005
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf
This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source |

| Event Text AGREEMENT STATE - RADIOGRAPHY SOURCE FAILED TO RETRACT
"On October 4, 2010, the Arkansas Radiation Control Program was notified by Team Industrial Services, Arkansas license number ARK-0344-03320, involving the failure of a radiography source to retract into the camera. The radiography crew involved in this incident was based in Sulphur, Louisiana.
"On October 3, 2010, radiography work was being conducted in Fulton, Arkansas using a rented SPEC-300 Camera, serial number 017, containing a 27 Curie SPEC G-70 source, serial number GE2503, both manufactured by Source Production and Equipment Company. The source was last leak tested on 10/1/2010. A J-Tube manufactured by QSA, owned by the licensee, was also employed in the radiography work.
"The source was cranked out of the SPEC-300 and the radiographer was unable to retract the source back into the camera. The radiography crew contacted the RSO and the crew attempted to safely straighten out the guide tube. After realigning the guide tube, the source was retracted into the camera.
"After the source was determined to be safely stored in the camera, the crew returned to the office to determine the cause of the inability to retract the source. SPEC was also notified.
"At this time, no overexposures have been reported by the licensee.
"The Radiation Control Program is awaiting a written report on the incident from the licensee."

| Event Text LOCKING MECHANISM MALFUNCTION ON RADIOGRAPHY CAMERA
On October 9, the radiography crew working the Kuparuk Oil Field on the North Slope of Alaska experienced a malfunction of the locking system on an INC IR-100 exposure device.
After completing radiography activities, the source was cranked in and the camera was surveyed per the proper procedure. There were no abnormal readings observed during the survey and the key was turned to the lock position. When the crank assembly was removed it was noted that the pigtail was not fully seated.
The 2 mR/Hr boundary was reconfirmed and the Radiation Safety Supervisor was notified. A trained radiographer came to the site and removed the locking system and cleaned it. The locking system was successfully reinstalled. The camera has been returned to service.

"On October 11, 2010 in preparation for maintenance, the 'A' Reactor Protection System Bus was being transferred from the normal to the reserve power supply. As a part of the transfer, a half scram is expected. During the transfer a [full] reactor scram occurred. All rods inserted to their full-in positions.
"Following the reactor scram, all systems operated as expected. Reactor vessel inventory is being maintained by the Condensate / Feedwater system.
"Following the scram, the Unit 2/3 Emergency Diesel Generator auto started due to the transfer of the Auxiliary Power system.
"Currently the cause of the full Reactor Protection System [scram] is unknown. Troubleshooting is in progress to determine the malfunction.
"This condition is being reported pursuant to 10 CFR 50.72(b)(2)(iv)(B), Any event or condition that results in actuation of the reactor protection system (RPS) when the reactor is critical."
The auto-start of the EDG was expected as a result of the 'A' RPS bus transfer and has been secured and placed back in standby. Decay heat is being discharged to the condenser. The Unit is in a normal shutdown electrical line-up. The scram had no impact on Unit 2. The licensee characterized the scram as uncomplicated.

"On October 11, 2010 at 1305 CDT it was identified that the analysis of record for the Technical Specification 3.3.5.1, Table 3.3.5.1-1 function 1e and 2e, Reactor Steam Dome Pressure Permissive-Bypass timer (Pump Permissive) did not reflect current plant conditions. Specifically, the analysis was not updated to account for any increase in plant licensed power and a change to the RWCU (Reactor Water Cleanup System) isolation for enhanced ability to isolate RWCU on a line break on critical crack. The allowable value for these function is greater than or equal to 18 minutes and less than or equal to 22 minutes.
"All equipment associated with emergency core cooling function are unaffected. Discussion with General Electric indicates that a margin exists to accommodate the higher power level. Additionally, the changes to the RWCU isolation logic added leak detection instruments that will isolate RWCU earlier for the majority of pipe leaks. This discovery is being reported as an unanalyzed condition solely due to the lack of a formal analysis of current plant conditions."
