Event Notification Report for July 01, 2014

OFFSITE ALERT AND NOTIFICATION SYSTEM FAILURE

"At approximately 0715 (CDT) on 7/1/2014, during the daily morning test, Braidwood Generating Station experienced Offsite Alert and Notification System (ANS) failure of sirens BD10 and BD13 due to a loss of power to the sirens. Loss of power to the sirens was due to the adverse weather conditions experienced on the evening of 6/30/2014. Siren BD10 provides coverage for 20% of Braidwood's Emergency Planning Zone (EPZ) population and siren BD13 provides coverage for 14.1% of the Braidwood EPZ population.

"This event is being reported in accordance with 10CFR50.72(b)(3)(viii) for 'any event that results in a major loss of emergency assessment capability, offsite response capability, or offsite communications capability (e.g., significant portion of control room indication, Emergency Notification System, or offsite notification system).' The failure of the sirens resulted in the loss of the capability to alert a large segment of the population in the EPZ (~34%) for more than 1 hour. Per NEI 13-01, Rev 0, a large segment of the population in the EPZ should be taken to mean
approximately 25% of the total EPZ population.

"Immediate actions taken included placing a portable generator online to restore siren BD10 at 1015 CDT on 7/1/2014. ComEd is currently in the area attempting to restore normal power. Proposed long term corrective actions including an upgrade to the sirens to contain a battery backup are being evaluated.

"The licensee has notified the NRC Resident Inspector. The county emergency managers (for Will County - [for siren] BD10 and Grundy County - [for siren] BD13) are aware of the siren outage and the requirements to initiate mobile route alerting (FEMA approved backup) if required."

* * * UPDATE FROM MURTAZA ABBAS TO DANIEL MILLS AT 1756 EDT ON 07/02/2014 * * *

"Siren BD10 was restored to functional on 7/1/2014 at 1130 CDT.
"Siren BD13 was restored to functional on 7/2/2014 at 1145 CDT.

"The NRC Resident Inspector has been notified of this ENS update."

FAILURE OF AIR OPERATED SOURCE CALIBRATOR

"On July 1, 2014, at approximately 1500 EDT, as a result of an investigation into a report that the electronics associated with the air operated source controller of a J. L. Shepherd Model 149 Neutron Calibrator was not working properly, it was concluded that the electronics for the air operated source controller had failed. The failure would have allowed the source to be withdrawn without the electronic circuit being energized. The original source contained 8.5 Ci of Pu-Be. The calibrator is designed to expose a neutron source on a signal from a control circuit using air to withdraw the source. In this event, source withdrawal was initiated when air was aligned without the control circuit being energized; the air was immediately isolated preventing the source from being withdrawn. The calibrator has been removed from service due to the control circuit failure. The source is in the safe position, tagged and locked with the air line disabled. This failure did not result in any personnel exposure.

"This is reportable under 10 CFR 70.50(b)(2) since the circuit is required by design to be operable when the calibrator is used. The cause of the failure has not been determined at this time.

"The affected calibrator is not part of any installed plant equipment and has no impact on plant operation."

The licensee has notified the NRC Resident Inspector.

The licensee will notify the New York Public Service Commission.

AGREEMENT STATE REPORT - TROXLER MOISTURE/DENSITY GAUGE RUN OVER BY BULLDOZER

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

"On July 2, 2014, the CRSO [Corporate Radiation Safety Officer], for Terracon Consultants (TCI) notified LDEQ [Louisiana Department of Environmental Quality] that a moisture density gauge being used at one of their projects was run over by a bulldozer.

"The source was left unattended when a bulldozer ran over the gauge and damaged the housing. They are conducting an investigation to determine the cause of the incident. It appears that it was human error.

"The sources were leak tested and TCI is waiting for the results of the test. The unit was surveyed and it appears the sources were not leaking. Results will be forwarded to NMED as an update when the information is obtained.

"All equipment involved is isolated and is not a threat to the public. There is no threat to TCI personnel and it appears to be safe.

"The damaged gauge was a Troxler, Model 3430, S/N 26346, loaded with 8 mCi of Cs-137 and 40 mCi of Am-241/Be. The gauge housing was damaged, but there was no indication the radioactive sources were compromised or leaking. The sources were isolated and leak tested."

AGREEMENT STATE REPORT - MISSING TRITIUM EXIT SIGNS

The following was received from the State of Nebraska via facsimile:

"During the annual inventory certification cycle for Pacific Ethanol Aurora West, the licensee discovered two missing tritium signs. These signs were originally shipped March 3, 2011 with 11.5 curies of material. Current approximate activity calculated as of 12/29/2015 is 8.77 curies. Pacific Ethanol Aurora West shut down for an estimated 18 months between 2012 and 2014. It is assumed these signs went missing at this time."

The missing exit signs are Isolite SLX-60 with serial numbers 435489 and 435495.

Item number: NE150003

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.
