The gauge was | | discovered in a pad-locked transport container at a construction site | | (approximately 180th and Harrison) in Omaha, Nebraska. Thiel Geotech is | | licensed to use/hold similar gauges, and representatives of Thiel Geotech | | transported the gauge to their office in order to secure it. | | | | The State reported that the gauge (model CPN-131, serial number MD00105439) | | contained a maximum of 50 millicuries of americium-241/beryllium and a | | maximum of 10 millicuries of cesium-137. At the request of the State, Thiel | | Geotech broke through the padlock to check the gauge and to perform surveys. | | There was no observable damage, and the survey results were normal. The | | State was able to identify the owner of the gauge fairly soon via an | | ownership label and the serial number. | | | | At approximately 1239 CDT on 07/23/02, Geotechnical Services, Inc., notified | | the Nebraska Division of Radioactive Materials of the loss of the same | | gauge. Geotechnical Services, Inc., also notified local law enforcement. | | | | The Nebraska Division of Radioactive Materials has had several conversations | | with both companies and has also been in contact with local law enforcement. | | The State requested Thiel Geotech to hold the gauge pending the State's | | investigation, which is currently planned for tomorrow. | | | | (Call the NRC operations officer for a Nebraska Division of Radioactive | | Materials contact telephone number.) | +------------------------------------------------------------------------------+ . !!!!!!!!!

Following the | | surgery, the technician discovered that only 7 instead of 8 of the original | | 110 seeds delivered to the OR [Operating Room] were remaining. A survey of | | the area was unable to locate the missing seed [338 millicuries]. The RSO | | believes that either the missing seed was inadvertently washed down the OR | | sink drain during cleanup or that 103 instead of 102 seeds prescribed were | | implanted. The licensee will submit a written report within 30 days. | +------------------------------------------------------------------------------+ . +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 39098 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: SUSQUEHANNA REGION: 1 |NOTIFICATION DATE: 07/27/2002| | UNIT: [1] [2] [] STATE: PA |NOTIFICATION TIME: 01:04[EDT]| | RXTYPE: [1] GE-4,[2] GE-4 |EVENT DATE: 07/26/2002| +------------------------------------------------+EVENT TIME: 21:24[EDT]| | NRC NOTIFIED BY: DAVID T.

Site Engineering and the vendor have been contacted to provide | | guidance on the affect of the argon gas on the Storage System. Temperature | | monitoring is in progress to detect any changes in the loaded canister until | | a final determination can be made. Because of the reduction in the thermal | | conductivity of the argon/helium mixture, this defect is believed to | | represent a potential significant reduction in the effectiveness of the | | spent fuel confinement system and is reportable under 10 CFR 72.75(b)(2) and | | 10 CFR 72.75(b)(3)." | | | | The NRC Resident Inspector has been notified. | +------------------------------------------------------------------------------+ . +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 39099 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: SUMMER REGION: 2 |NOTIFICATION DATE: 07/27/2002| | UNIT: [1] [] [] STATE: SC |NOTIFICATION TIME: 13:36[EDT]| | RXTYPE: [1] W-3-LP |EVENT DATE: 07/27/2002| +------------------------------------------------+EVENT TIME: 01:10[EDT]| | NRC NOTIFIED BY: JIM TURKETT |LAST UPDATE DATE: 07/27/2002| | HQ OPS OFFICER: FANGIE JONES +-----------------------------+ +------------------------------------------------+PERSON ORGANIZATION | |EMERGENCY CLASS: NON EMERGENCY |MARK LESSER R2 | |10 CFR SECTION: | | |NINF INFORMATION ONLY | | | | | | | | | | | +-----+----------+-------+--------+-----------------+--------+-----------------+ |UNIT |SCRAM CODE|RX CRIT|INIT PWR| INIT RX MODE |CURR PWR| CURR RX MODE | +-----+----------+-------+--------+-----------------+--------+-----------------+ |1 N Y 100 Power Operation |100 Power Operation | | | | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | INFORMATION CALL THAT INVOLVES LOCAL AUTHORITIES AND POSSIBLE MEDIA | | ATTENTION | | | | The licensee's security personnel discovered a stub end of a hand rolled | | cigarette of questionable material in the room above diesel generator 'A.' | | It appeared old and had no odor.
