The | | #2 Emergency Diesel Generator had previously been removed from service for | | maintenance activities. Upon discovery that the #1 Emergency Diesel | | Generator was inoperable, action was immediately initiated to restore the #1 | | Emergency Diesel Generator to Operable status. These actions were completed | | and the #1 Emergency Diesel Generator was restored to Operable status at | | 1830 hrs on 02/18/02. | | | | "The #1 Diesel Generator was rendered inoperable at 1406 hrs on 02/14/02. | | During the period of inoperability, the licensee conducted core alterations | | including core reload during the ongoing ninth refueling outage. During the | | affected period, there were no challenges to the offsite power sources, and | | core cooling was maintained. Investigation into this event is ongoing. | | | | "This event is being reported under 10CFR50.72(v)(A) and 10CFR50.72(v)(B) as | | a loss of Safe Shutdown Capability, and RHR Capability, respectively. There | | were no radiological releases associated with this event," | | | | The licensee intends to notify the NRC Resident Inspector. | +------------------------------------------------------------------------------+ !!!!!!!!!

On sending the active sources to the target | | area, a fluid leak occurred which slowed the movement of the seeds into the | | target vessel/position (Left Anterior Descending Artery). Not able to see | | the active seeds on the fluoroscopy monitors, a decision to have the active | | seeds returned to the holding device was made. A total time of 17 seconds | | elapsed from the time of delivery until the active seeds were returned to | | the holding device. | | | | On close inspection of the treatment catheter/device, one of the sealing | | O-rings was found to be ruptured. This was the ultimate cause of the fluid | | leak and consequently the slow movement of the active seeds to the target | | position. | | | | With a dose rate of 0.095 Gy/s at 2 mm, the artery wall along the | | approximately 1 m track over which the source traveled out and back for its | | 17 sec would be calculated as: | | | | Speed equals 2 * (100 cm)/17 s = 11.8 cm/s | | | | Time wall was exposed to the 4 cm source = 4 cm / 11.8 cm/s = 0.34 s, but | | this time is doubled since it is exposed coming and going, to 0.68 s. | | | | Dose to the wall = 0.68 s * 0.095 Gy/s = 0.0646 Gy = 6.5 rads. | | | | The normal dose to the wall (assuming an 8 s round trip) would be 3.0 rads. | | | | A new catheter was tested with the non-active device and the treatment was | | continued. The treatment was timed, checked for the return of the active | | sources and surveyed the patient/room post treatment. No problems were | | encountered with the new treatment catheter. | | | | * * * UPDATE 1745EST ON 2/19/02 FROM ABDUL BEN-ZIKRI TO S. SANDIN VIA E-MAIL | | * * * | | | | The following is a portion of an e-mail received at hoo1@nrc.gov: | | | | "I am retracting my event report (Event # 38708). I took a conservative | | action and reported this event based on preliminary written information. | | | | "Our Hospital staff followed all standard operating & emergency procedures, | | and retracted the source when they realized that they did not arrive to the | | area of clinical interest as indicated in the report below. Based on the | | investigation analysis, we conclude that there was no misadministration to | | report." | | | | Notified R3DO(Jorgensen) and NMSS(Brach). | | . | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Other Nuclear Material |Event Number: 38709 | +------------------------------------------------------------------------------+ *** NOT FOR PUBLIC DISTRIBUTION *** +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | REP ORG: PRINCETON UNIVERSITY |NOTIFICATION DATE: 02/19/2002| |LICENSEE: PRINCETON UNIVERSITY |NOTIFICATION TIME: 11:35[EST]| | CITY: PRINCETON REGION: 1 |EVENT DATE: 01/23/2002| | COUNTY: STATE: NJ |EVENT TIME: [EST]| |LICENSE#: 290518524 AGREEMENT: N |LAST UPDATE DATE: 02/19/2002| | DOCKET: |+----------------------------+ | |PERSON ORGANIZATION | | |MICHAEL MODES R1 | | |JOHN HICKEY NMSS | +------------------------------------------------+ | | NRC NOTIFIED BY: SUE DUPRE | | | HQ OPS OFFICER: FANGIE JONES | | +------------------------------------------------+ | |EMERGENCY CLASS: NON EMERGENCY | | |10 CFR SECTION: | | |BAB2 20.2201(a)(1)(ii) LOST/STOLEN LNM>10X | | | | | | | | | | | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | MISSING RAT CARCASSES CONTAMINATED WITH TRITIUM | | | | On 1/23/02 the Radiation Safety Officer was informed that 15 rat carcasses | | contaminated with 14 mCi of tritium were missing from the freezer. This was | | discovered on 1/21/02 when a scheduled pickup for disposal was made and the | | 2 bags of rat carcasses were not located. A thorough search of the | | laboratories and freezers was made. It is believed that the 2 bags were | | mistakenly picked up on 11/7/01 when a scheduled pickup for disposal of | | non-contaminated rat carcasses was made. The 2 bags were last seen in | | October when the bags were placed in the freezer. | | | | New procedures have been put in place to prevent this event from being | | repeated. A written report will be submitted within 30 days. | +------------------------------------------------------------------------------+
