AGREEMENT STATE REPORT - INTERNAL LEAD SHIELDING OF GAUGE SOURCE HOLDERS MELTED

The following information was received via facsimile:

"The Alabama Office of Radiation Control received a call at 0820 CDT on 3/25/13 from Dr. Michael Hensley of RSO Services (AL license No. 1482), a gauge service company. He had been contacted by IIG, MinWool, LLC in Phenix City, AL (AL license No. 986) to assist them with an issue. The licensee melts rock in a cupola to make insulation. The cupola has two Ohmart Model SR-A devices, one at the top and one at the bottom of the cupola, each containing a 100 mCi Cesium-137 source. The cupola was superheated to about 3,500 degrees Fahrenheit above the operating limits for the Model SR-A devices. It is believed the lead shielding in the devices liquefied, but because the source holders are sealed, the lead was contained inside the devices and did not leak out.

"Dr. Hensley surveyed the devices and found a maximum reading of 2.5 mR/hr at 12 inches from the back of the device which was located at the top of the cupola. This is lower than the design maximum exposure of 4.8 mR/hr with a 100 mCi source per the SSDR. The shutters on both devices were still operable, and were closed and locked. Dr. Hensley will remove the devices and prepare them for shipment to Ohmart."

ONE EMERGENCY WARNING SIREN ENERGIZED FOR A SHORT TIME

"At 2245 [EDT] on 3/27/2013, Surry Power Station (SPS) Operations Department received a report from Virginia State Emergency Operations Center (VEOC) that a concerned citizen had called James City County (JCC) law enforcement to report that an Early Warning System (EWS) siren, #62 in James City County NW side of Route 682, was sounding. VEOC reported JCC police received call at 2240 [EDT] from a concerned citizen that an EWS siren was sounding. SPS Security contacted JCC police and subsequently reported that JCC police responded approximately 10 minutes later to the site of the siren, but the siren was no longer sounding. Maintenance will investigate in the morning. All plant conditions/parameters are normal and no releases to the environment have occurred.

"The site NRC Resident Inspectors have been notified.

"This notification is being transmitted due to notification of other Government Agencies in accordance with 10CFR50.72(b)(2)(xi)."

The licensee also notified the state and local governments.

* * * UPDATE FROM JASON SWEATMAN TO STEVE SANDIN ON 4/2/2013 AT 1710 HOURS * * *

"This report is being retracted based upon the following:

"On 3/28/13, an activation verification test was performed. The results of the test indicated EWS siren #62 did not activate. In addition, when a siren activates, the battery voltage decreases. A review of the battery voltage trend for siren #62 found no such decrease, verifying no activation occurred. Maintenance staff reported to the siren location and confirmed the siren did not activate. They also found no indication of tampering or intrusion. Three local homeowners were interviewed and stated they did not hear any siren activation.

"By all available indications, EWS siren #62 was functional and did not activate on 03/27/13.

"NRC Site Resident Inspectors have been notified of the retraction."

Notified R2DO (McCoy).

OFFSITE NOTIFICATION DUE TO ELECTRICAL FAULT IN SWITCHYARD RESULTING IN PERSONNEL INJURIES

"At 1707 CDT on 4/2/13 an arc flash occurred at the 'B' safeguards transformer (XMDV24) in the plant switchyard at Callaway. At the time of the flash, ground straps were being placed on the 'B' safeguards transformer which had been removed from service for maintenance. The event resulted in a loss of power to areas/buildings outside the power block. There was no impact to equipment and systems in the plant.

"Four workers were injured or affected by the flash. The extent of the electrical-related injuries has not been determined. However, based on reports from the scene, all of the workers were conscious and walked away from the scene. One person was transported by helicopter and two by ambulance to a local hospital. The fourth person experienced only a minor injury.

"The hazard has been isolated and investigation of the cause is in progress.

"Notifications of this event are planned to be made to OSHA and the Missouri Public Service Commission."

The licensee notified the NRC Resident Inspector.
