| ENS 52658 | 3 April 2017 14:45:00 | 10 CFR 20.1906(d)(2) 10 CFR 20.1906(d)(1) | Exclusive Use Transport Vehicle Exceeded Contact Dose Rates | This is being reported under 10CFR20.1906(d)(1,2). At 1045 hours (EDT), the SSES (Susquehanna Steam Electric Station) Radwaste shipper was notified by the RP (Radiation Protection) shipping technician performing a receipt survey of an open transport vehicle shipped exclusive use carrying an empty radwaste liner exceeded the 10CFR71.47(b)(1) vehicle contact dose rates of 200 mR/hr. Per NDAP-QA-0720 (Nuclear Department Administrative Procedure) Attachment E, contaminated /radioactive shipments this is a 1 hour notification for exceeding the radiological receipt survey requirements of 200 mR/hr at any point on the outer surface of the vehicle. The vehicle was from Energy Solutions. The licensee will be using the vehicle to transport radwaste from the facility. The licensee has notified the Pennsylvania Emergency Management Agency and the NRC Resident Inspector. | ||
| ENS 48178 | 7 August 2012 21:34:00 | 10 CFR 20.1906(d)(1) | Dry Fuel Storage Transfer Trailer Detected with Removable Contamination | On Aug 7, 2012 at 1734 EDT, PPL Susquehanna personnel were in the process of releasing the Dry Fuel Storage Transfer Trailer from the Unit 1 Reactor Building 101 rail bay and detected removable contamination on the trailer. PPL Susquehanna Health Physics personnel identified removable surface contamination up to 30,000 dpm/100 sq cm on the transfer trailer. Gamma spectroscopy performed on smears identified the presence of Cs-137. No other radionuclides were identified on any of the analyzed smears. Cs-137, by itself, is not a nuclide characteristic to Susquehanna due to Susquehanna's high fuel integrity performance. In addition, no loose surface alpha contamination was identified. The area around the trailer, located in the 101 bay, has been posted and controlled as a contaminated area. Decontamination of the transfer trailer is in progress. Onsite surveys of areas that were occupied by the transfer trailer, indicate no removable surface contamination. In addition, no Susquehanna personnel contamination events have been attributed to the contamination found on the transfer trailer. Although the receipt of this transfer trailer was not identified as an incoming radioactive shipment to Susquehanna from its' supplier, this event is immediately reportable to the NRC Operations Center in accordance with 10 CFR 20.1906(d), since the Department of Transportation acceptance limits identified in 49 CFR 173.433 for this type of container are 22,000 DPM/100 sq. cm and PPL Health Physics personnel identified removable radioactive surface contamination in excess of the limits of 10 CFR 71.87(i) which refer to the DOT limits of 49 CFR 173.433. The final delivery carrier and NRC Senior Resident Inspector have been notified." The licensee will be notifying the Commonwealth of Pennsylvania. | ||
| ENS 43918 | 18 January 2008 22:03:00 | 10 CFR 20.1906(d)(2) 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Offsite Notification Due to Receipt of Package That Exceeded Allowable Contact Dose Rate | At 1703 EST on 1/18/2008, Susquehanna LLC personnel became aware that a shipment received from GE Hitachi Nuclear Energy exceeded the allowable limit of 200 mr/hr contact dose rate. The external radiation limit of 200 mrem/hr was exceeded on one of the two boxes comprising the shipment. The limit per NDAP-QA-0648 is 200 mrem/hr on contact for a shipment type for a transport vehicle which is not designated exclusive use. The actual value was determined to be 350 mrem/hr, therefore reportable per the requirements of 10CFR20.1906(d)(2). The NRC Resident Inspector and the Shipper (GE Hitachi Nuclear Energy) were notified. The transport vehicle left Wilmington NC on 1/17/2008 at 1435 and was received by SSES (Susquehanna Steam Electric Station) on 1/18/2008 at 0800. There was no surface contamination noted on the shipment. The original survey completed prior to shipment noted the highest on contact dose rate was 170 mr/hr. This item is reportable under 50.72(b)(2)(xi) for offsite notification of an event of public interest. The boxes contained various pieces of equipment that GE uses to support refueling. The licensee has notified the NRC Resident Inspector and will be notifying the Pennsylvania Emergency Management Agency. | ||
| ENS 42824 | 1 September 2006 15:15:00 | 10 CFR 20.1906(d)(2) | Shipment Exernal Radiation Levels in Excess of Limits | At 1115 EDT on 9/01/2006, Susquehanna LLC personnel became aware that a shipment received from another site exceeded the 10CFR71.47(b)(2) limit of 200 mr/hr contact dose rate. Contact dose rates on the bottom of the shipment are 820 mr/hr, and therefore reportable per the requirements of 10CFR20.1906(d)(2). There is no identified surface contamination on the shipment, and the shipment only exceeded the dose rate limit on the bottom once it was lifted off the transport trailer. Doses under the trailer prior to lifting the shipment did not exceed the limit The transport company and the originating site have been notified. The transport vehicle left the Vermont Yankee facility on 8/31/06 and was received by SSES on 9/1/06 at 0805." . . . The driver has been contacted by the transport company. The vehicle made two stops during transport. The first was at the first rest stop traveling west on the Massachusetts Turnpike. The second was at the first rest stop on I-87 south after exiting I-90. No one to the knowledge of the driver came in contact with the shipment. The driver arrived at Susquehanna on 8/31/06 at 2045, and slept in the truck. The driver was wearing dosimetry (TLD). The licensee will notify State of Pennsylvania Emergency Management and has notified the NRC Resident Inspector. |
