| MEDICAL EVENT |
| |
| At 1300 CDT on 7/9/03, an underadministration of Yttrium-90 (Y-90) occurred |
| at the University of Wisconsin Hospital in Madison, WI. A patient being |
| treated for secondary liver cancer was to receive a dose of approximately 50 |
| millicuries of Y-90. The dose was delivered using a SIRTECH (Selective |
| Radiation Implantation) to pulse microspheres of Y-90 from a vial into the |
| liver via a needle and catheter. |
| |
| During the procedure, the SIRTECH did not develop enough pressure to deliver |
| the entire dose to the patient, and only about 8 percent of the Y-90 was |
| delivered to the patient (between 3-4 millicuries). The remainder of the |
| Y-90 microspheres were contained within the vial. |
| |
| There was no adverse affect on the patient due to this underadministration, |
| and the licensee is still investigating how to prevent a re-currence. The |
| patient was notified of the underadministration. |
| |
| * * * RETRACTION AT 0615 EDT ON 07/17/03 FROM BRESELL TO GOTT * * * |
| |
| The licensee determined that the technician had misinterpreted the |
| measurement of the Y-90 administered to the patient and determined that the |
| correct amount of Y-90 was administered. Because the correct amount of Y-90 |
| was administered, the licensee is retracting the event. The licensee |
| discussed this with Deborah Piskura, NRC Region III. |

| Notified R3DO (Riemer) and NMSS EO (Pierson) |

| UNDECLARED UNUSUAL EVENT |
| |
| At 0501 CDT on 07/17/03 the shift manager determined that a condition |
| existed for 10 minutes the previous evening which met the emergency plan |
| criteria but no emergency was declared. The basis for the emergency class |
| no longer existed at the time of discovery. Upon discovery he notified the |
| NRC Operations Center and the NRC Resident Inspector. |

| 24-HOUR NRC 91-01 BULLETIN NOTIFICATION INVOLVING LOSS OF CRITICALITY |
| CONTROL |
| |
| The following is a portion of text from a fax submitted by the licensee: |
| |
| "Pump-Out to UNBSS Without Sample Results. |
| "Reason for Notification: An operator pumped out a batch from the clean |
| dissolver to the uranyl nitrate bulk storage tank prior to receiving the |
| required sample results for grams U-235 per liter, percent free acid, and |
| pH. |
| |
| "Double Contingency Protection: Double contingency protection for the bulk |
| storage tank is based on concentration control. Concentration control is |
| based upon maintaining uranyl nitrate that is pumped to the tanks at less |
| than 5 grams U-235/liter. The pH is maintained at a value of less than 2 to |
| ensure that the uranyl nitrate stays in solution. The percent free acid is |
| maintained at greater than 4 percent to ensure that the uranyl nitrate stays |
| in solution and depresses the freezing temperature of the solution to |
| prevent concentration by freezing. |
| |
| "It has been determined that less than previously documented double |
| contingency protection remained for the system and that greater than a safe |
| mass was involved., but a sufficient number of controls that were lost were |
| restored within 4 hours. In accordance with Westinghouse Operating License |
| (SNM-1107), paragraph 3.7.3 (c.5b), this event satisfies the criteria for a |
| 24-hour notification. |
| |
| "As Found Condition: See 'Reason for Notification' above. |
| |
| "Summary of Activity: (1) Pump outs to the bulk storage tanks were |
| stopped, (2) Samples for grams U-235/liter, pH, and %free acid were taken to |
| ensure the tanks were in specification, (3) Before the end of the shift, |
| sample results for grants U-235/liter, pH, and %free acid were determined to |
| be acceptable. |
| |
| "Conclusions: (1) Loss of double contingency protection occurred, (2) |
| Greater than a safe mass was involved, (3) At no time was the health or |
| safety to any employee or member of the public in jeopardy. No exposure to |
| hazardous material was involved, (4) The Incident Review Committee (IRC) |
| determined that this is a safety significant incident in accordance with |
| governing procedures, (5) Notification was the result of an event, not a |
| deficient NCS analysis, (6) A causal analysis will be performed." |
| |
| The licensee attributes the cause of this incident to personnel error. The |
| licensee will inform both NRC Region 2 and the NRC Headquarters PM. |
