AGREEMENT STATE REPORT - SOURCE RECEIVED WITH EXTERNAL CONTAMINATION

The State reported that QSA Global received a radioactive source shipment that had external contamination on the source (but internal to the shipping container) and evidence of leakage. The source originated from Westex Company of Oxnard, California. The source was an old Amersham source Model T-2-T, S/N C778 containing an estimated 7.1 curies of Cobalt-60. The source was sent to QSA for disposal. It had been in long-term storage at the Westex facility.

When the shipment arrived at QSA, it was receipt inspected and found to be clean on the outside of the Type B shipping package. When the package was opened and interior swipes taken, surface contamination was discovered on the source exterior. The highest swiped reading obtained was about 1.17 microCuries of Co-60.

QSA does not believe that any contamination ever existed exterior to the package during transport or preparation of shipment at the originator's site. The source has been stored in the container at Westex without use or removal from the container for decades. QSA Global has been in contact with Westex about the contamination and Westex confirmed no contamination at their facility.

QSA plans on disposing of the source.

AGREEMENT STATE REPORT - NUCLEAR DENSITY GAUGE DAMAGED WHEN STRUCK BY VEHICLE

The following information was received via facsimile:

"A nuclear gauge, Troxler Laboratories 4640 Thin Lift density gauge, Serial No. 1997, Nuclide CS-137, GBq 0.296, mCi 8, was damaged in a construction zone hit-and-run accident. The RSO for a construction company was carrying the thin lift gauge to his truck when he was struck by a female driver in a grey sedan. The RSO, who was approximately 10 feet inside the coned area of the construction control zone, was able to move his body at the last minute and did not sustain major injuries. The gauge was destroyed but the source remained intact in the damaged housing. The RSO and the Nevada Highway Patrol [NHP] conducted radiation surveys.

"NHP contacted Radiation Control Program 30 minutes after notified. The licensee reported to RCP within 3 hours.

"The damaged gauge has been leak tested and is stored at the licensee's facility pending instruction from Troxler on shipping for disposal."

The State of Nevada has not yet assigned a state event number.

HIGH DOSE RATE AFTERLOADER STUCK / EXPOSED SOURCE

On 9/20/10, the licensee was having scheduled maintenance work performed on a Varian High Dose Rate (HDR) afterloader. A source exchange was also scheduled to be performed. During the source exchange, the source became "stuck, partially exposed, not fully shielded in the shield" of the HDR machine and became inoperable. The licensee believes this to be due to personnel error on the part of the service technician. The service technician then vacated the room.

Varian was called and said they would dispatch personnel to the hospital on 9/21/10. Security was notified of the radiation safety problem. The door to the room was secured. The door to the room was posted with hazard warning tape, with a do not enter sign, and with a high radiation area sign. The department was also locked down.

Varian personnel arrived on-site on 9/21/10. Varian service personnel secured the source back in the machine. Radiation levels in the room then returned to normal background readings. The source wire was found kinked and shipped out today. The hospital is scheduled to receive a new source and have it installed tomorrow.

Service personnel were wearing "active monitors" and received only a few milli-rem during the repair operation. It is not known at this time how much dose the first service technician received.

AUTOMATIC REACTOR TRIP

"At 2017 [EDT] on 9/21/10, Turkey Point Unit 4 spuriously tripped. The cause of the reactor trip is currently under investigation.

"At the time of the trip, reactor power was 100%. Auxiliary feedwater [AFW] was automatically initiated when steam generator levels lowered below the actuation setpoint. Steam generator levels are now stable at their normal Mode 3 band and auxiliary feedwater is secured.

"Unit 4 has been stabilized in Mode 3 on normal off-site power.

"This event is reportable per 10 CFR 50.72(b)(2)(iv)(B) - actuation of the reactor protection system with the reactor critical and 10 CFR 50.72(b)(3)(iv)(A) - valid actuation of an ESF system (AFW)."

All control rods inserted into the core. Decay heat is being removed through the steam dumps to atmosphere. There was no activation of PORVs or SRVs. The reactor is at shutdown NOP and NOT. The reactor trip response was uncomplicated and there was no impact on Unit 3.

The licensee notified the NRC Resident Inspector.
