"The Auxiliary Feedwater System was inoperable due to elevated hotwell temperatures from 1720 to 1739 EDT on 6/30/13. At no time was there a risk to the health and safety of the public. The elevated hotwell temperatures resulted from the loss of multiple cooling tower fans due to a lightning strike.
"Cooling tower fans and hotwell temperatures have been restored. Power was slightly reduced solely to maintain condenser vacuum until cooling tower fans were restored."
At Catawba, the hotwell is a credited water supply for the auxiliary feedwater system. The unit is currently in a power ascension back to 100%. No other plant equipment was affected by the lightning strike.
The licensee will be notifying the state warning points in both North and South Carolina and local warning points in Gaston, York, and Mecklenburg counties. They have notified the NRC Resident Inspector.
* * * RETRACTION FROM TOM GARRISON TO VINCE KLCO ON 8/4/13 AT 0357 EDT * * *
"Catawba Nuclear Station is retracting EN #49161 based on completion of evaluation of auxiliary feedwater system operability. The engineering department performed this evaluation using existing plant conditions during the event to verify existing safety analyses remain bounding and conservative. The evaluation concluded that sufficient volume of secondary condensate was available below the required temperature from the Upper Surge Tanks (USTs), in combination with the hotwell inventory as normally aligned, for the auxiliary feedwater system to remain operable during this event. This condition is not reportable under 10CFR50.72(b)(3)(v)(B)."
The licensee will notify the NRC Resident Inspector, State and Counties.

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text MISSING TROXLER MOISTURE DENSITY GAUGE
The Radiation Safety Officer (RSO) at the Idaho Transportation Department discovered a Troxler 3440 moisture density gauge missing when it was believed to be in lock-up and a wipe test was to be performed on July 18, 2013. The Idaho Transportation Department searched all the projects and alerted everyone in the district that the gauge was missing. After a week, the gauge could not be located.
Gauge Information: Troxler Model 3440, Serial # 26155
Sources: Americium-241/Beryllium, 40 millicuries; Cesium-137, 8 millicuries
* * * UPDATE FROM DIANNA HOFFECKER TO VINCE KLCO ON 7/26/13 AT 1307 EDT * * *
The gauge has been found and is in the possession of the licensee. Notified R4DO (Allen), FSME Events Resource, ILTAB and Canada..
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.

| Event Text EXTERNAL RADIATION LEVELS ON SHIPMENT EXCEEDED 2MR/HR LIMIT FOR UNMONITORED EXPOSURES
"The conditions for reporting under the requirements of 10 CFR 20.1906(d) have been met. QWI 14.1.10, Classification & Notification Criteria for Unusual Incidents Radiation Protection section - for shipments, bases reporting requirements on receipt of a shipment with radiation or contamination levels in excess of 10 CFR 20.1906(d). This requirement was exceeded and an NRC report is required. The truck cab sleeping area (normally occupied space) dose rate of 5.4 mrem/hr is greater than the allowable limit of 2.0 mrem/hr. The carrier drivers (2) state that they do not have dosimetry.
"Immediate actions that have been taken:
- The area was secured.
- Confirmatory measurements were taken.
- Digital photographs have been taken.
- The shipper has been notified.
- A review of the associated regulations was performed.
- The carrier has been notified.
- The truck has been unloaded and released."
The shipment contained Am241/Be sources sent from QSA Global in Burlington, MA for use in refurbishing sources, typically well-logging. The estimated departure time/date was 0800 EDT on 07/31/13 with estimated arrival time/date of 0800 EDT on 08/01/13. The driver team consisted of two (2) individuals during the 24-hour transit time. The shipment was off-loaded and secured following the receipt rad survey.
The licensee notified the shipper, the carrier, the Commonwealth of Virginia and informed the NRC Resident Inspector. |

"[On August 3, 2013, at 0520 CDT], Farley Unit 1 declared an ALERT emergency based on [EAL] HA3, 'Release of Toxic, Asphyxiant, or Flammable Gas'. This was due to a tagout of the CO2 Fire Protection System, which resulted in an unexpected discharge of CO2 on the Unit 1 Radiation Side of the Auxiliary Building. The 100 foot elevation level on Unit 1 had an oxygen concentration below the required amount. CO2 has been isolated at the source tank in order to terminated the leak. No personnel have been affected. There is no radiation release in progress. ERDS has been activated."
The licensee is assembling a team to enter the affected area and verify oxygen levels are within allowable limits in order to terminate the ALERT emergency.
The licensee has notified the NRC Resident Inspector and the State and local organizations.
Notified DHS SWO, DOE, FEMA, HHS, DHS NICC, USDA, EPA, FDA and NuclearSSA via email.
* * * UPDATE FROM JONATHAN MCCORY TO STEVE SANDIN AT 1215 EDT ON 08/03/13 * * *
Farley Unit 1 terminated from the ALERT at 1110 CDT on 8/3/13. Oxygen levels are acceptable in all areas of the plant. The CO2 tank has been isolated and is stable at 68%. Plant conditions are stable and improving and all necessary compensatory measures are in place.
The licensee has notified the NRC Resident Inspector and applicable state and local authorities.

| Event Text CONTAMINATION FOUND IN PROCESS BUILDING
"While Health Physics (HP) technicians were checking radiological control wrapping in the Uncomplicated Handling (UH) waste storage area on the ground floor of the C-337 Process Building, contamination was discovered on the floor around some valve subassemblies. A Contamination Area (CA) was set up to establish contamination boundaries. Due to the contamination spread, access requirements for the area will be increased for more than 24 hours. Decontamination efforts are underway but will not be completed within 24 hours from the time that radiological controls were increased.
"This event is reportable as a 24 hour event in accordance with 10 CFR 76.120(c)(1)(i) 'An unplanned contamination event that: requires access to the contaminated area, by workers or the public, to be restricted for more than 24 hours by imposing additional radiological controls or by prohibiting entry into the area'.
"The NRC Resident Inspector has been notified of this event.

An interim report was made, as required per 10CFR21.21 (a)(2), of a deviation identified by AMEC Environment & Infrastructure, Inc. The CTLGroup, a supplier of AMEC, did not initially provide all the traceable calibration information required for all the chemicals used in performance of procured tests in regard to laboratory test data of screening tests for constituents related to Safety Class C concrete and grout. An evaluation is underway, but could not be completed within 60 days of discovery. AMEC anticipates that the evaluation will be completed within two weeks of this correspondence, August 17, 2013.
Affected plants;
Vogtle Units 3 & 4 Safety Class C Concrete and Grout and VC Summer Units 2 & 3 Safety Class C Concrete and Grout.
