| STATE LICENSEE REPORTED THAT THREE OF TEN I-125 SEEDS WERE LOST IN THE
SEWER |
| DRAIN |
| |
| At 2:30pm on June 13, 2002 the radiation safety officer (RSO) for City of |
| Hope National Medical Center reported that during the course of an |
| iodine-125 prostate permanent implant procedure, three of the ten seeds were |
| lost down the autoclave sink located in the operating room. |
| |
| The initial report from the preliminary investigation was that the operating |
| room technician wanted to wash off the three seeds prior to autoclaving |
| them. They were not going to be used in the procedure. During this process |
| they ended up being washed down the drain of the autoclave sink. Although |
| this occurred at approximately 5:00pm on June 12, 2002, the RSO was not |
| notified until approximately noon on June 13, 2002. They requested the RSO |
| investigate the reason(s) for the delay in reporting the incident. The |
| activity of the iodine -125 seeds was 0.344 mCi each (for a total of 1.032 |
| mCi) at 5:00pm on June 12, 2002. At noon on June 13, 2002 the activity was |
| 0.340 mCi (for a total of 1.02 mCi). |
| |
| On June 14, 2002 a request was made to remove the sink trap and piping in an |
| effort to locate the seeds. At approximately 10:00am it was reported that |
| the seeds were not located, even with the use of a NaI probe and visual |
| examination. This information was forwarded to ICE Supervisor for reporting |
| to the NRC. |

| POTENTIAL FOR HOT-SHORT CAUSING THE RWST TO DRAIN |
| |
| "On 6/7/02, Wolf Creek Nuclear Operation Corporation notified Callaway Plant |
| of a potential hot short issue involving the possibility to drain the |
| Refueling Water Storage Tank to the containment recirculation sump during a |
| fire. Initial evaluations indicate a potential for this issue to be |
| applicable to Callaway Plant. |
| |
| "The issue discovered was that control cables for 2 redundant motor operated |
| valves are routed in the same electrical raceway. The 2 valves are on the |
| same electrical separation group, but are redundant in their function of |
| conserving water inventory in the RWST. Further investigation determined |
| that the other electrical separation group has the same configuration. The |
| licensee has implemented an hourly fire watch as a compensatory action. |
| Engineering analyses are being conducted to determine if further |
| modifications are necessary. Appropriate changes or compensations will be |
| instituted into the corrective action system as identified." |
| |
| The licensee informed the NRC Resident Inspection. |
