AGREEMENT STATE REPORT - SOURCE RETRACTION FAILURE

The following was received from the State of Texas via email:

"On June 3, 2013, the Agency [State of Texas] was notified by the licensee that on June 3, 2013, a medical event had occurred. The licensee reported a source retraction failure with a Novoste Beta-Cath intravascular brachytherapy system containing a 45.1 mCi strontium - 90 source. When the treatment was completed, upon source retraction, the source got stuck in another area of the blood vessel roughly 5 cm away from the treatment site for 1 minute.

"The unintended absorbed dose to that area of the vessel is in the range of 5-6 Gy. The source open in air time was roughly 3 seconds from being retracted from the patient before being secured in a bail out box. Personnel exposure issues or concerns are not expected, however, dosimeters will be assessed. A technical representative was notified and during the next several days will inspect the system and assist in packaging the system for return shipment back to the manufacturer. Additional information will be provided as it is received in accordance with SA-300."

Texas Incident #: I-9088

A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.

UNIT 1 AUTOMATIC REACTOR TRIP DUE TO THE LOSS OF A START-UP TRANSFORMER

"This is a report of an automatic RPS actuation and automatic ESF actuation per 10CFR50.72(b)(2)(iv)(B) and 10CFR50.72(b)(3)(iv)(A). Additionally, this is to report intentions for a press release per 10CFR50.72(b)(2)(xi).

"At 2105 CDT on 6/11/13, Farley Unit 1 experienced an automatic reactor trip from 100% power. The initiating event was the loss of the 1B Start up Transformer which resulted in de-energization of the B-Train ESF 4KV buses and the 1B and 1C Reactor Coolant Pump Buses. The 1B Emergency Diesel Generator auto started and tied to the B-Train 4KV Emergency buses.

"Both MDAFW (Motor Driven Auxiliary Feedwater) Pumps and the TDAFW (Turbine Driven Auxiliary Feedwater) Pump auto-started and are supplying AFW flow to the steam generators. Decay heat removal is via the steam dumps to the main condenser.

"The cause of the loss of the 1B Start-up Transformer is unknown and is currently under investigation. All other systems functioned as expected in response to the loss of the 1B Start-up Transformer and reactor trip.

"The NRC Senior Resident Inspector has been notified.

"A press release is planned."

All control rods fully inserted. There is no impact on Unit 2. Currently the licensee does not plan to restart the 1B and 1C Reactor Coolant Pumps. Pressurizer spray has been isolated from the 1B loop per procedure. Main Condenser vacuum is adequate for decay heat removal.
