The investigation into the extent of the potential noncompliance continues including whether associated elements of 10 CFR 26.63 are in compliance. Safety related construction activities will be suspended pending resolution and completion of corrective actions.
Southern Nuclear Operating Company (SNC) is providing this notification under the provisions of 10 CFR26.719(b)(4)."

The licensee will notify the Public Service Commission of Georgia and the NRC Construction Inspection Staff.

MATERIAL CONTROL AND ACCOUNTABILITY (MC&A) ALARM ACTUATION

"10 CFR 74.57(f)(2) requires notification within 24 hours that an MC&A alarm resolution procedure has been initiated. Because the alarm investigation has been initiated, this notification is being made. There is no indication that a material loss has occurred. "

Material processing operations related to this alarm have been suspended.

The NRC Resident Inspector has been notified.

* * * UPDATE FROM RANDY SHACKELFORD TO DONG PARK AT 1509 EDT ON 7/6/10 * * *

The investigation from the MC&A alarm resolution procedure has been successfully completed. No material loss occurred, and the alarm was caused by the material being held up in the process.

Notified R2DO (Widmann), NMSS EO (Pstrak), and Fuels OUO Group via email.

AGREEMENT STATE REPORT - STOLEN TROXLER MOISTURE DENSITY GAUGE

"[The State of Florida] received [a] report from company's RSO at 1030 hrs today that a soil moisture density gauge and case were stolen yesterday July 1st at 1830 hrs from a truck parked in a lot near the MIC Earlington Heights jobsite in Miami. FL. Thief or thieves apparently used bolt cutters or other device to cut chain used to secure transportation locked box which contained said gauge, then took both transportation box and gauge. Miami-Dade police were contacted (case# PD 100701276792). The licensee will offer a reward for information helping in the recovery. The incident was assigned to the Miami Inspection office for investigation. This office will take no further action on this incident."

The Troxler gauge (Model 3440; S/N 23094) contained 40 mCi AmBe and 8 mCi Cs-137.

Florida Incident Number: FL10-079

THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

ONSITE LEAK FROM CONDENSATE STORE TANK RESULTING IN LOCALIZED TRITIUM CONTAMINATION

"This notification is being made pursuant to 10 CFR 50.72(b)(2)(xi) due to the notification of the Illinois Emergency Management Agency (IEMA) and the Illinois Environmental Protection Agency (IEPA) of an unpermitted release of radionuclides at LaSalle County Station. This notification was made at 0903 on July 1, 2010. A news release is planned, which is also reportable under 10 CFR 50.72(b)(2)(xi), this notification satisfies the additional reporting requirement.

"On June 30, 2010, a small leak of radioactive water from the Unit 1 Cycled Condensate Storage (CY) Tank to the ground was confirmed by analysis of water from an adjacent groundwater test well. The IEMA / IEPA require notification when a release to soil, groundwater or surface water results in tritium concentrations of 200 pCi/I or more outside the licensee controlled area, or contains tritium at quantities of 0.002 Curies or more on-site. Positive groundwater test well sample result was obtained at 1800 on June 30, 2010 from the well adjacent to the Cycled Condensate Storage Tank. Samples found a tritium concentration of 715,000 pCi/I, with a confirmatory sample result of 696,000 pCi/I. The concentration of tritium in the sampled well makes it likely that the release is in excess of 0.002 Curies.

"Based on sampling data obtained to date, the tritium in the groundwater is confined to Exelon property and poses no threat to public safety. The Station continues to track this issue by monitoring groundwater test wells. Plans to repair the leak in the Unit 1 CY tank are in progress."

The licensee has notified the NRC Resident Inspector and State authorities. The licensee also plans to notify authorities and will be issuing a press release.

AGREEMENT STATE REPORT - STUCK GAUGE SHUTTERS

The following information was provided by the State of Mississippi via e-mail:

"During inspection and review of licensee's gauge service reports, two gauges were discovered to have stuck shutters. Both gauges are Ronan models SA1-F37. Ronan service engineering was called in to repair gauges and determined that on gauge serial # 9473GG, the bottom bushing was found frozen to the shutter shaft. On gauge serial # M4122, the roll pin was broken and the shutter handle was rotated 45 degrees out of alignment. Both gauges were repaired.

Both gauges had a Cs-137 source. Gauge #M4122 was 5 millicuries and gauge #9473GG was 200 millicuries.
