"Notification of a possible medical event per 10 CFR 35.3045 - a brachytherapy procedure in which the administered dose may differ from the prescribed dose by more than 0.5 gray to an organ and the total dose delivered may differ from the prescribed dose by twenty percent or more.
"Permittee: VA Medical Center, Philadelphia, PA
"Event: The event occurred on May 5, 2008, and was discovered on May 15, 2008.
"Description: A permanent implant prostate brachytherapy procedure was performed on May 5, 2008, using I-125 seeds. Seeds of a lower apparent activity than intended were mistakenly ordered and implanted. A CT scan of the patient was performed on May 6, 2008, and a postplan was performed on May 15, 2008. The D90 dose, calculated from the postplan, was less than eighty percent of the prescribed dose. Postplans based on CT scans performed approximately one month after an implant, when swelling from the procedure has partially resolved, are believed to provide more accurate assessment of dose to the prostate. It is intended to obtain another CT scan and postplan at about this time to better assess the prostate dose. The permittee intends to make a determination at that time regarding whether a medical event did occur. The permittee will complete a causal analysis and implement procedural changes to prevent a recurrence before any additional brachytherapy procedures are performed.
"Effect on Patients: The VA is continuing to evaluate this event. At this time, adverse effects to the patient are not expected.
"Patient notification: The permittee is ensuring that the referring physicians and patients were notified.
"Licensee will notify the NRC Project Manager, Cassandra Frasier, of NRC Region III."
* * * UPDATE ON 6/06/08 AT 18:16 EDT FROM LEIDHOLT TO HUFFMAN * * *
"This is an amendment to NRC Event Number 44219 and is a notification of possible medical events per 10 CFR 35.3045.
"The VHA National Health Physics Program notified the NRC Operations Center on May 16, 2008, of a possible medical event at the VA Medical Center, Philadelphia, Pennsylvania, involving transperineal permanent seed implant prostate brachytherapy.
The VHA National Health Physics Program initiated a reactive inspection on May 28, 2008. As part of this reactive inspection, the medical center was requested to review additional brachytherapy procedures.
Based on a review of other brachytherapy procedures performed between February 1, 2007, and May 31, 2008, the medical center identified an additional four brachytherapy procedures that may be medical events because the D90 doses, determined from post-implant CT scans, were more than 20 percent less than the prescribed doses. The procedures are still under evaluation and a final determination has not been made.
VHA is continuing to evaluate these possible medical events. At this time, adverse effects to the patients are not expected.
If these patient procedures are determined to be medical events, the medical center will ensure that the referring physicians and patients are notified.
VHA has notified NRC, Region III (NRC Project Manager, Cassandra Frasier).
R1DO (Henderson), R3D(Pelke), and FSME (Chang) notified.
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. |

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text LOUISIANA AGREEMENT STATE REPORT - LOST WELL LOGGING TOOL
"[On the morning of May 29, 2008], a Pulsed Neutron Generator (Source #183619) belonging to Baker Hughes Oilfield Operations, Inc. dba Baker Atlas, containing approximately 900 millicuries of Tritium (H-3) was lost into the waters of the Mississippi River. The events were as follows:
"A commercial hotshot carrying two complete Pulsed Neutron Tools was dispatched to the Hilcorp dock in Cocodrie, La., from the Baker Atlas facility in Broussard, La. at approximately 3 A.M. this morning [5/29/08].
"The tools arrived at the Hilcorp dock at approximately 5 A.M.. The shipment was verified by the Hilcorp dock dispatcher and loaded onto a Hilcorp contracted Crew Boat. Note: there were no Baker Atlas employees included in the transport of this shipment. The Baker Atlas crew was already at the rig when this equipment was ordered.
"The shipment arrived at Hilcorp S/L 3090 #7, in the Little Pass field at approximately 7 A.M.. At arrival, the Hilcorp company representative noted that the aluminum tubes containing the Baker atlas downhole tools were not strapped down and were extended over the rail of the boat.
"The Hilcorp representative alerted the Baker Atlas crew, who conducted an inventory of the equipment and found that one tube containing both the upper section and lower section [containing the 900 milliCurie H-3 source] of a Pulsed Neutron Generator Tool was missing.
"The Hilcorp representative dispatched the crew boat back to the dock to conduct a visual search of the route and dock, but nothing was found. Due to the weight and density of the equipment, it is most likely that the tube (and tools in it) sank to the bottom of the river. Note: the rig is approximately 20 nautical miles from the dock.
"The customer (Hilcorp) has accepted financial responsibility for this loss and does not believe that a search for the missing equipment would be cost effective."
The State of Louisiana considers this event closed.
Louisiana DEQ Event Report ID: LA0800011
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
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.
Although IAEA categorization of this event is typically based on device type, the staff has been made aware of the actual activity of the source, and after calculation determines that it is a Less than Cat 3 event.
Note: the value assigned by device type "Category 3" is different than the calculated value "Less than Cat 3" |

The following information was received from the State of California Radiologic Health Branch [RHB] via email:
"On Tuesday, June 3, 2008, RHB was notified by NRC Region IV of an incident involving a California licensee. A package had been shipped by the California licensee to an Illinois licensee. The package should have contained 23 iodine-125 seeds used for brachytherapy, with activities of approximately 0.425 millicuries each. Upon receipt, the outer package was undamaged, but was reading 460 millirem/hour on contact. When the package was opened, the inner shielded container was open and some of the seeds were out of the shielded container, and at the bottom of the shipping container. The IL licensee could only account for 19 of the 23 seeds. They notified the IL radiation control program, and contacted [the carrier]. The IL licensee has surveyed the delivery truck, and the loading dock. They are in the process of surveying the [carrier's] terminal at Chicago's O'Hare airport. The California licensee that made the shipment is a small surgical center. Based on the information from IL, the package was not prepared for shipment in accordance with the instructions provided by the IL licensee, and vibrations during the shipment appear to have caused the shielded container to open during the shipment, releasing some of the seeds. RHB will be investigating the root cause of this incident and corrective actions with the California licensee."
CA Incident Number 5010-060308
* * * UPDATE FROM BARBARA HAMRICK TO HOWIE CROUCH VIA EMAIL ON 6/3/08 @ 1626 HRS. EDT * * *
"As of 1:02 pm PDT, we [RHB] received notification from the IL radiation control program that their licensee found the four missing I-125 seeds at the licensed facility in IL, among other packages received that morning. All seeds are now accounted for. California will continue to investigate the root cause of this incident."

"On 6/04/08 at 0257, the High Pressure Coolant Injection (HPCI) system was declared inoperable. The HPCI pump was placed in service to evaluate HPCI pump start performance. The HPCI pump tripped on low suction pressure when started. An Event Response Team is assembled to investigate the cause of the low suction trip of HPCI.
"Loss of the HPCI system is reportable under 10 CFR 50.72(b)(3)(v) as loss of a single train safety system required to mitigate the consequences of an accident. No additional Emergency Core Cooling Systems or Safety Related equipment was inoperable during this time period."

The licensee notified the NRC Resident Inspector.
* * * RETRACTION ON 6/6/08 AT 1933 EST FROM LITKETT TO HUFFMAN * * *
"The purpose of this notification is to retract a previous report made on 6/04/08 at 0758 (EN# 44263). The High Pressure Coolant Injection (HPCI) system was declared inoperable. The HPCI pump was placed in service to evaluate HPCI pump start performance. The HPCI pump received a momentary low suction pressure trip signal in the test configuration alignment.
"Since the initial report, failure mode cause technical evaluation has determined that the HPCI was always able to satisfy its design safety function. Additional instrumentation was added and data collected from seven HPCI test runs was analyzed. As evidenced by the successful completion of its IST test and the detailed review of multiple HPCI runs, the HPCI system was always able to perform its design function because:
--- HPCI restarted on its own with no operator action.
--- HPCI would meet its injection time requirements.
--- Required flows and required pressures were reached on all HPCI runs .
"Therefore HPCI was never inoperable.
"The NRC resident has been informed of the retraction."

"Below are the responses to questions BWXT received from [a reporter] at the News & Advance of Lynchburg, VA, regarding the closure of the Barnwell Facility in South Carolina.
"Q: I understand that the Nuclear Regulatory Commission has announced new guidelines for the storage of low-level radioactive material since the disposal site in Barnwell, S.C. plans to close. Does B&W ever use the Barnwell Facility for any disposal needs, or will that facility's closure affect B&W operations here in any way? If so, I'd like to discuss those potential effects and perhaps write an article about the issue."
"A: Annually, the B&W Lynchburg facility generates approximately 15 to 20 cubic feet of Class B and C waste, which was disposed of at the Barnwell site in South Carolina. However, the Lynchburg facility has not been significantly impacted by Barnwell's closure."

"During the performance of stator water low flow testing a turbine trip and subsequent Reactor trip occurred on low cooling flow to the main generator rectifier. An Automatic Emergency Feedwater actuation signal occurred on low steam generator level due to unit trip. This is an expected actuation for a turbine/reactor trip from 100% power. The Engineered Safety Function Actuation operated as designed.
"On the Unit trip, the main feedwater pumps exhibited large rpm oscillations. Operators tripped one of the non-safety related main feed pumps, and placed the second in manual which stabilized the main feedwater system. When conditions allowed, operators placed the operating main feed pump in automatic control."
All rods fully inserted successfully. All emergency systems operated as required. No PORV's or Safety valves lifted during this event. Auxiliary Feedwater system is available, but not in use at this time. RCPs are in operation transferring decay heat to steam generators. Main steam is being directed to main condenser via bypass.

"On Thursday June 5, 2008 at 2356 MST Palo Verde Nuclear Station Unit 1 initiated a normal reactor shutdown to comply with condition C of Technical Specification (TS) LCO 3.5.1 and to facilitate a weld repair on a nitrogen leak found on the Safety Injection Tank (SIT) 1A vent line.
"LCO 3.5.1 requires that all four SITs be operable in Modes 1 and 2. On June 5, 2008, at 0225 hours MST, Unit 1 entered Condition B which provides allowance for one SIT to be inoperable for a 24 hour period. The SIT will not be restored to operable status within the TS required 24 hour period, therefore, Condition C will be applicable at 0225 MST on June 6 2008. Condition C requires shutdown to Mode 3 in six hours and to reduce pressurizer pressure to less than 1837 psia within 12 hours.
"On June 06 at 0148 hours MST, Unit 1 was manually tripped from approximately 20% power. The shutdown did not result in a release of radioactivity to the environment and did not adversely affect the safe operation of the plant or health and safety of the public. The primary plant is being stabilized in Mode 3 in forced circulation with both steam generators used for heat removal. Unit 1 is stable at normal operating temperature and pressure in Mode 3."
