VIRGINIA AGREEMENT STATE REPORT - DOSE RECEIVED BY PATIENT GREATER THAN PRESCRIBED

The following information was obtained from the State of Virginia via fax:

"On August 7, 2011, the licensee's RSO received notification of an incident. A patient was treated for bronchial/trachea carcinoma using temporary brachytherapy employing a HDR delivery system. Subsequent to treatment, it was realized that dwell positions were misrepresented on the approved treatment plan. Reconstruction of the applicator position led to the conclusion that dose to organs or tissue other than the treatment site received more than 50 Rem and more than 50% of the expected dose. Licensee notified Virginia Department of Health on August 17, 2011. Referring physician was notified on August 17, 2011. Physician is meeting with patient on August 19, 2011. Licensee indicated organs at risk and health effects to patient are under development."

Virginia Report ID: VA-11-08

* * * UPDATE AT 1458 EDT ON 09/02/11 FROM MIKE WELLING TO S. SANDIN * * *

The following update was received from the State of Virginia via email:

"On August 31st the licensee report was received. The report indicated the cause was human error during data loading into the delivery system. An error was received and in order to clear the error the source position spacing was changed. The report detailed the licensee's dose calculations to the surrounding organs and tissue. The estimated maximum amount received by the larynx was 2.332 Gy which was 581% over the expected dose of 0.42 Gy.

"A subsequent licensee response on September 1st detailed the dose to the lungs. The dose to the lungs did not differ between expected and delivered.

"The patient has had two follow up visits and shows no adverse effects. A positive tumor effect was observed by the referring physician."

Notified R1DO (DiPaolo) and FSME (Hsueh).

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.

AGREEMENT STATE - LOST GADOLINIUM CAMERA SOURCES

The following report was received via facsimile.

"The (New Jersey) (Bureau of Emergency Response) BER received a call from the (Radiation Safety Officer) RSO at Trinitas Hospital at 1500 (EDT) on Monday August 29, 2011. This past Friday, while performing an inventory of their sealed sources, it was discovered that two (Gadolinium) Gd-153 camera sources were missing. These sources were dated March 2002, with an initial activity of 250 mCi apiece. (The half-life of Gd-153 is 241 days, therefore each source had decayed to ~0.01 mCi). The RSO stated that these sources were never used on the camera, and had been in storage since 2002. During the last routine inventory (July 2011) the sources were accounted for. Friday's inventory was being conducted as a result of a recent cleanup of the storage area. The RSO indicated that hospital staff conducted thorough searches of the hospital on Friday, as well as over the weekend, but have not found the sources. It was also indicated that the chief nuclear medicine technologist, who was involved in the cleanup, is currently overseas until September 7. When he returns, the RSO will discuss with him to see if he has knowledge of the location of these sources."

The search and investigation is still ongoing.

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. 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

24-HOUR REPORT DUE TO FAILURE OF A GAMMA MONITORING SYSTEM

"On 8/28/11 at 0920 hrs. PDT, electrical storms in the area caused power surges. The site backup power generators activated as designed. However, it was later discovered that a gamma monitor associated with the waste water treatment process was damaged. When the gamma monitoring system failed, the system interlocks shut the system down as designed. The system has remained down since that time and will remain down until repaired.

"This report is being made per the requirements of 10 CFR 70, Appendix A(b)(4), (24-hr. report criteria), 'Any natural phenomenon that has affected the availability or reliability of one or more Items Relied On For Safety (IROFS)'.

"An updated report with additional timeline information will be provided as the information becomes available.

"SAFETY SIGNIFICANCE OF EVENTS: Low. The waste water treatment system was shut down as designed.

"POTENTIAL CRITICALITY PATHWAYS INVOLVED: The only potential pathway is gradual accumulation of uranium in the waste water treatment equipment over an extended period of time.

"CONTROLLED PARAMETERS: Concentration is controlled. Maximum concentration in the equipment is estimated to be less than 1.5 grams of uranium per liter based on gamma monitor reading when the system shut down.

"ESTIMATED AMOUNT/ENRICHMENT, FORM OF LICENSED MATERIAL: Facility is licensed for 5 wt% U-235. Normal system clean out results in about 120 grams of uranium. A minimum critical mass assuming spherical geometry is [much greater than normal system content].

"CORRECTIVE ACTIONS: System automatically shut down as designed and will remain down until the equipment is repaired and returned to service.

* * * UPDATE AT 1214 EDT ON 09/02/11 FROM CALVIN MANNING TO S. SANDIN * * *

The following information was received via email:

"At approximately 0920 local time, 8/28/2011 and closely associated in time with both a thunderstorm and a test of various internal backup power generators, an operator at the Waste Water Treatment (WWT) facility noticed that the gamma monitors on two sand filters had ceased to function correctly. Apparently as an immediate result of this failure to function, the associated flows to the sand filters shut down automatically (normal fail-safe shutdown). The system has remained down since that time and will remain down until the gamma monitoring system is repaired.

"This plant condition was brought to the attention of the HRR EHS&L staff on Tuesday 8/30/2011 at 0800 by an engineer responsible for the gamma monitoring system who was soliciting potential options to restore the system to service.

"At 0901 local time AREVA's HRR EHS&L notified the NRC Operation's Center of this condition per the requirements of 10CFR70 Appendix A criterion (b) (4) (24 hour report) which requires reporting of any natural phenomenon that has or may have affected the intended safety function or availability or reliability of one or more items relied on for safety.

"Safety Significance of Event: The safety significance of this event is low. The feed and discharge to and from the waste water treatment sand filters were shut down as designed when the gamma detectors failed.

"Potential Nuclear Criticality Pathways Involved: The only potential pathway is for gradual build up / accumulation of uranium in the WWT equipment over an extended period of time (many years).

"Controlled Parameters (Mass, Moderation, Geometry, Concentration, Etc.): Uranium concentration is controlled. The maximum concentration of uranium in the equipment is estimated to be less than 1.5 g U/L based on gamma monitor readings just prior to the system being shut down.

"Estimated Amount, Enrichment, Form of License material (Includes process limit and % worst case critical mass): The facility is licensed for 5 wt.% U-235. Normal system clean out results in about 120 grams of uranium. A minimum critical mass of uranium at 5 wt.% U-235 assuming spherical geometry is about 38,000 grams.

"Nuclear Criticality Safety Control(s) or Control System(s) and description of the failures or deficiencies: No control system failures occurred.

"Corrective Actions to Restore Safety Systems and When Each Was Implemented: The system automatically shut down as designed and will remain down until the equipment is repaired, functionally tested, and returned to service."

AGREEMENT STATE REPORT INVOLVING A FIXED NUCLEAR GAUGE SHUTTER THAT FAILED TO CLOSE

The following information was received from the State of Illinois via email:

"Late yesterday the Agency's [Illinois Emergency Management] W. Chicago office received a call from PDV Midwest Refining (IL-01603), 135th St and New Ave., Lemont, IL 60439. The caller reported that while his crew was performing routine shutter checks of fixed gauges in his area of the plant, a shutter failed to close. The vessel the gauge was on was in use as part of a sulfur unit and needed to remain in operation with the gauge 'on-line', so no other immediate action was taken other than to advise all shift supervisors of the gauge's status and to avoid performing any work in the area.

"This morning, the radiation safety officer was contacted for additional information and instructions regarding necessary actions on their part. The RSO advised that the gauge was an Ohmart model SH-F1-45, containing 15 milliCi of Cs-137 as of April 2002. It was one of two gauges on that vessel. The other gauge which was lower on the vessel showed no difficulties in its operation. However, he noted that a similar problem had occurred in the past with the same model gauge on a parallel sulfur unit in the same physical position. At that time, field notes prepared by the manufacturer's representative who inspected the device indicated that some corrosion was present on the device. Both vessels and thus all four gauges are exposed to the full range of seasonal cycles of weather. All site staff have been made aware of the gauge condition and to ensure all 'lock out - tag out' practices are in effect in the area to preclude any work on the vessel until such time the manufacturer's rep has repaired the device or removed it from the vessel.

"The radiation safety officer was advised of the need to file a written report within 30 days in keeping with Illinois regulations.

INTAKE STRUCTURE FIRE SUPPRESSION SYSTEM FAILED SURVEILLANCE TEST

"During intake structure fire suppression sprinkler system surveillance testing, Operations identified that a portion of the sprinkler system was not able to pass flow. A 14-day fire protection system impairment was entered and a continuous compensatory fire watch with backup suppression was stationed prior to removing the system from service for testing. Upon failure of the surveillance test, the impairment remained in effect and the continuous fire watch remained stationed pending investigation/repair by Maintenance. On 9/2/2011 at approximately 1600 [CDT], Mechanical Maintenance personnel informed Operations that the sprinkler suppression piping was found to be fouled and not capable of passing flow. The intake sprinkler system is relied upon in part to satisfy an exemption for the station to 10CFR50 Appendix R, Section III.G.2.B concerning separation of components in the intake structure. Based upon the intake sprinkler system being non-functional, this condition is being reported under 10CFR50.72(b)(3)(ii)(B) as an unanalyzed condition affecting plant safety systems."

TECHNICAL SPECIFICATION REQUIRED SHUTDOWN DUE TO "A" TRAIN SERVICE WATER LEAK

A leak in the "A" train of the service water system was identified on August 17, 2011. The leak is in the auxiliary building at the minus 5' elevation and the water is being collected in the waste drain tank. At 1530 on September 3, 2011, the leak was quantified as being less than 15 gpm and the service water system was declared inoperable in accordance with Technical Specification (TS) 3.7.4.1 for the Service Water System and the Technical Requirements Manual 3.4.10 for Structural Integrity. The leak is on a 10" flange between two bolt holes in a welded area of the flange. Maintenance has been able to reduce the leakage to approximately 3 gpm.

The plant is in a 72 hour Tech Spec and is making preparations to shutdown to mode 5 for repairs.

The licensee notified the NRC Resident Inspector and will notify state and local authorities.
