| DISCOVERY OF A BRACYTHERAPY MISADMINISTRATION INVOLVING A LEAKING IODINE-125 |
| SOURCE AT THE UNIVERSITY OF PENNSYLVANIA IN PHILADELPHIA |
| |
| At approximately 1000 on 05/04/01, the licensee administered a prostate |
| implant involving the 94 iodine-125 seeds on the order of about 1/2 |
| millicurie per seed. (It is currently believed that the intended dosage for |
| the patient was approximately 47 millicuries. The licensee reported that |
| the intended dose is received from decay of the seeds which remain in the |
| patient after treatment.) |
| |
| Surveys were performed after the administration, and one of the implant |
| needles had readings that were higher than expected. At that time, it was |
| assumed that a source was stuck in the applicable needle (a more likely |
| scenario). However, at approximately 1630, removable contamination (due to |
| a leaking source) was discovered on the applicable needle. It is currently |
| believed that one of the seeds may have been damaged during the needle |
| loading process, and that the damaged seed was implanted into the patient |
| during treatment administration. |
| |
| At this time, there is only complication that is expected as a result of the |
| leaking iodine-125 source. It was reported that the activity from the |
| leaking source could get into the blood steam and that the thyroid would |
| filter the radio-iodine. Therefore, the patient may receive an unintended |
| thyroid dose. |
| |
| The authorized user was notified, and the patient was informed. The patient |
| was also prescribed Lugols solution (a potassium iodide solution) to |
| minimize the unintended iodine-125 thyroid uptake from the leaking seed. |
| Initial estimates indicate a thyroid activity measurement of 73 nanocuries |
| (calculated based on normal thyroid turnover) to give a dose of about 320 |
| milleRem over the period that it will take for the iodine-125 to decay. |
| |
| The licensee plans to notify the referring physician. |
| |
| (Call the NRC operations officer for a licensee contact telephone number.) |

| MAIN TURBINE STOP VALVE FAILED TO CLOSE DURING TESTING |
| |
| The #4 main turbine stop valve failed to close during the performance of |
| turbine valve testing procedure. Failure of the turbine valve to close |
| affects the turbine stop valve closure scram function of both A&B reactor |
| protection trip systems. Reactor power is currently being reduced to less |
| than 45% power which is required when the minimum conditions for the turbine |
| stop valve closure scram function are not satisfied. The licensee believes |
| the cause of the problem is probably due to a bad solenoid valve. |
| |
| The NRC Resident Inspector will be notified. |
