Alert

Due to a lapse in appropriations, the NRC has ceased normal operations. However, excepted and exempted activities necessary to maintain critical health and safety functions—as well as essential progress on designated critical activities, including those specified in Executive Order 14300—will continue, consistent with the OMB-Approved NRC Lapse Plan.

SAFETY PARAMETER DISPLAY SYSTEM (SPDS) REMOVED FROM SERVICE FOR COMPUTER UPGRADE

"On 05/29/2007 at 08:08 am CDT, the Wolf Creek Nuclear Plant Information System (NPIS) was removed from service for a planned computer system upgrade. The system upgrade will result in the SPDS and Emergency Response Data System (ERDS) being inoperable for approximately three weeks.

"Wolf Creek Nuclear Operating Corporation is making this ENS notification pursuant to the criteria of 10 CFR 50.72(b)(3)(xiii). There is no other loss of emergency assessment capability concurrent with the removal of the NPIS from service. Plant personnel entered the appropriate Off-Normal procedure and will obtain local readings for the equipment that is normally monitored by SPDS and NPIS during the plant computer upgrade.

"The Senior NRC Resident has been briefed on this evolution and the planned return to service of the system."

* * * UPDATE FROM LANE TO SNYDER AT 1802 EDT ON 6/11/07 * * *

"On 06/09/07 at 18:46 CDT, the Wolf Creek Nuclear Plant Information System (NPIS) was returned to service following the computer upgrade. This restored the Safety Parameter Display System (SPDS) to OPERABLE and made the Emergency Response Data System (ERDS) available for use. The ERDS system will not be considered OPERABLE until testing has been performed with the NRC to confirm proper data transmissions.

"Some data points and processes are still being tested prior to being returned to service."

The licensee notified the NRC Resident Inspector. Notified R4DO (M. Hay).

* * * UPDATE FROM JIM KURAS TO JOE O'HARA AT 1633 EDT ON 6/13/07 * * *

"On 6/13/07 at 14:57 CDT (ERDS) testing with the NRC completed satisfactory to confirm proper data transmission."

The licensee notified the NRC Resident Inspector. Notified R4DO(Hay).

ALABAMA AGREEMENT STATE REPORT - A GEORGIA LICENSED MOISTURE DENSITY WAS DAMAGED IN ALABAMA

This event was received via facsimile from the State of Alabama

"SUBJECT: Alabama Incident 07-25 - Damage to Instrotek Model 3500 Moisture Density Gauge.

"On the morning of June 11, 2007 at approximately 8:05 am CDT, the Alabama Office of Radiation Control received a phone call from a representative of the Georgia Department of Natural Resources advising the Agency that a moisture density gauge containing radioactive material had been run over by a dozer at a temporary job site in Phenix City, Alabama. The gauge was an Instrotek model 3500, serial number 583 containing 10 millicuries of Cs -137 and 40 millicuries of Am-241:Be. The licensee, Building and Earth Sciences of Columbus, Georgia notified the Georgia Department of Natural Resources at the time the incident occurred. Upon notification, the writer called the licensee's technician at the site to check the status of the incident. According to the licensee, the sources were in the shielded position and the area was restricted. The licensee's Radiation Safety Officer arrived at the scene and surveyed the area, the dozer and the gauge. Radiation levels around the gauge were found to be within the normal range. The gauge was placed in the transport container and returned to the licensee's facility and a leak test was performed. Leak test results are pending. Building and Earth Sciences is authorized to possess and use radioactive material under their Georgia Radioactive Material License No. GA. 1136-1.

"This is all the information that this Agency has at this time and is current as of 3:00 pm CDT, June 11, 2007."

NOTIFICATIONS MADE FOR DETECTION OF TRITIUM IN ONSITE WATER SAMPLES

"On May 8, 2007, measurable levels of tritium were identified in two manholes (i.e., MW-5 and MW-6) that route cable to a nearby meteorological tower. The manholes are located within the boundaries of the site owner controlled area. The manholes are also in close proximity to the Storm Drain Stabilization Pond (SDSP). The SDSP is an area of approximately 64 acres consisting of a non-lined perimeter dike of approximately 12 to 15 feet in height. The site storm drain system collects in the storm drain collector basin and is then pumped to the SDSP. The storm drain collector basin receives overflow from the Turbine Building air-wash system, which contains very small amounts of tritium. By plant design, the tritiated water of the SDSP is then pumped into the intake canal during monitored, controlled releases, compliant with all permits and regulations.

"As a result of ongoing investigations to determine the source and potential migration path of the tritium, an increased environmental sampling program was initiated. On June 13, 2007, tritium levels in excess of Nuclear Energy Institute (NEI) voluntary reporting criteria were confirmed to be present in new onsite shallow groundwater wells.

"Immediate corrective actions taken were to perform additional sampling of areas surrounding the stabilization pond and [to reconfigure] the Turbine Building air-wash system. The reconfiguration of the turbine building airwash system will be done to eliminate the designed pathway of water to the storm drain collection basin and to the storm drain stabilization pond.

"Additional corrective actions include installation of additional monitoring wells at various locations to determine groundwater flow and checking for the presence of tritium.

"There is no indication that tritium has migrated into drinking water sources and all offsite monitoring has resulted in non-detectable levels of tritium. It is believed that the likely source of the tritiated water is seepage from the SDSP. The following agencies will be updated on the status of the onsite tritium samples and informed of the pending press release: State Officials, City of Southport, Brunswick County, NEI, INPO, and ANI."

The Licensee notified the NRC Resident inspector.
