ALERT DECLARED DUE TO INADVERTENT DISCHARGE OF CO2 INTO SWITCHGEAR ROOM
"At 1454 [EDT] an inadvertent discharge of CO2 occurred in the Division 3 switchgear room. The Control Building 261 foot (ground level) and below was evacuated. An ALERT emergency condition was declared at 1504 [EDT]. Emergency Response Facilities are being manned. NY State and Oswego County have been notified via the RECS line. Unit 1 was not affected. No personnel were injured. Unit 2 remains at full power. Cause is under investigation."
The licensee notified the NRC Resident Inspector.
* * * UPDATE FROM SKINNER TO HUFFMAN AT 23:46 EDT ON 9/19/07 * * *
The licensee terminated the ALERT at 2147 EDT on 9/19/07 base on restoration of free access in the control building and isolation of CO2 fire protection discharge systems in Unit 2. All the CO2 discharge systems were manually isolated because the licensee could not conclusively determine the cause of the fault that led to the initial inadvertent actuation. The licensee has established compensatory fire protection actions. Trouble shooting into the cause of the event continues. The licensee has notified the State and local authorities of the event termination. The NRC Resident Inspector has also been notified.
Regional and HQ NRC management have been notified including R1(Dapas), NRR (Dyer), IRD (McDermott), R1DO (Krohn), and NRR EO (McGinty). Notifications to external agencies initially notified of the event were made by the HOO.

OFFSITE NOTIFICATION OF UNKNOWN DISCHARGE AND 24 HOUR REPORT PER APPENDIX B OF OPERATING LICENSE
"[The information below concerns a] September 19, 2007 NPDES Reportable Occurrence verbiage/Notification to the Ohio Environmental Protection Agency. This notification was made on September 20, 2007.
"Time of discharge is unknown. Cloudy water was discovered in 'Major Stream' diversion (also referred to as 'Red Mill Run') at approximately 1525 hours on September 19, 2007.
"The amount of discharge is unknown. At the time of discovery, approximately 10 to 15 gallons of water, per minute, were observed discharging from the storm drain. On September 20, 2007, the observed discharge from the storm drain was approximately 1 to 2 gallons of water per minute.
"The pH of the stream was 11.2 standard units (SU) at 1650 hours on September 19, 2007 with white powdery deposition on the stream bed. At 1000 hours on September 20, 2007, a sample taken for pH indicated 8.48 SU.
"A number of small stressed fish were observed at time of discovery, along with approximately 5 to 10 small dead fish. No frogs, crayfish, or other local aquatic life forms were observed to have been negatively impacted.
"Initial analysis of the sediment from the stream bed indicated the main constituents were inorganic calcium & oxygen (possible materials include but not limited to calcium oxide, calcium carbonate, calcium hydroxide).
"The source of the high pH and white sediment is unknown at this time and an investigation is in progress.
"The affected area [has been inspected] and recommendations for clean-up remediation [provided]. The recommendations are currently being evaluated."
"This event is being reported in accordance with Appendix B to the Operating License (The Environmental Protection Plan) which requires reporting of any occurrence of an unusual or important event that indicates or could result in significant environmental impact causally related to plant operation (An example includes 'fish kills').
"This event is also being reported in accordance with 10CFR50.72(b)(2)(xi). 'Any event or situation, related to the health and safety of the public or on-site personnel, or protection of the environment, for which a news release is planned or notification to other government agencies has been or will be made. Such an event may include an on-site facility or inadvertent release of radioactively contaminated materials'."
The NRC Resident Inspector and applicable State authorities have been notified.

PART-21 DRY CASK CANISTER DOCUMENTATION LOST
"TN identified and documented in Supplier Finding Report 2007-111 that our fabricator, GE-Hitachi Nuclear Energy Americas (GHNEA), had provided inadequate fabrication records resulting in a nonconforming condition relative to the possibility of undocumented Temporary Weld Attachments (TWAs) to the confinement boundary of a loaded NUHOMS 32PTH Dry Shielded Canister (DSC) at Surry Power Station.
"This condition involves a lack of documentation for use of qualified welders, approved welding procedures, approved weld filler material and compatible TWA base material, as well as a lack of the required liquid penetrant surface examination report subsequent to TWA removal. Such documentation is required per Article NB-4435 of the ASME B&PV Code Section III, which is a design feature embedded in the Technical Specifications for the NUHOMS HD license.
"Based on the preliminary evaluation, it is concluded the subject DSC is capable of performing its design functions involving the structural integrity of the confinement boundary, heat removal, shielding and criticality control associated with the safe storage of spent nuclear fuel."
Four DSCs were shipped (three to Surry and one to North Anna) with insufficient documentation. The documentation for one of the Surry canisters was subsequently found. Of the remaining three DSCs, one at Surry, was loaded with spent fuel.
* * * UPDATE FROM TRANSNUCLEAR (NEIDER) TO HUFFMAN AT 1537 EST ON 12/20/07 * * *
As of 1530 EST on 12/19/07, the licensee determined that a second Dry Shielded Canister (DSC) shipped to Surry that is loaded with spent fuel has undocumented Temporary Weld Attachments (TWAs). The original report above noted that only one DSC (serial # DOM-32PTH-001-C) with TWAs had been loaded with spent fuel at Surry. The licensee had believed that documentation for another one of the loaded DSCs had been subsequently found. Upon further review, Transnuclear has determined that Surry DSC, Serial# DOM-32PTH-003-C (loaded with spent fuel), has other undocumented TWAs that were not initially recognized.
Furthermore, two additional DSCs were shipped to Surry that have undocumented TWAs. Specifically, a total of six casks have been shipped with the undocumented TWAs of which five were sent to Surry and one to North Anna. Two of the five at Surry have been loaded with spent fuel. A hold has been place on the three remaining empty DSCs at Surry and one empty DSC at North Anna. In addition, all DSCs still at the licensee's fabricators with possible undocumented TWAs have also been placed on hold. Based on this new information, the licensee is expanding the scope of its initial report.
R2DO (Shaeffer) and R1DO (Henderson) notified. In addition, NMSS (Pstrak), FSME EO (Mohseni) and Part 21 coordinators (Hodge and Thorpe) have been notified.
