Event Notification Report for August 06, 2015

NON-FUNCTIONAL EMERGENCY SIRENS

"At 1200 CDT, on August 6th, 2015, during the monthly test of Emergency Plan sirens in Saint Charles Parish (county), all sirens failed to actuate when required. There are a total 73 sirens of which 37 sirens are in Saint Charles Parish, which covers approximately 49 percent of the total population within the Waterford 3 10-mile emergency planning zone. The siren vendor is currently investigating to repair the issue.

"Waterford 3 still maintains 100 percent backup notification capabilities.

"The Saint John the Baptist Parish Sirens remain fully operational.

"The Saint Charles Parish Emergency Manager has been notified.

"This event did not result in any adverse impact to the health and safety of the public. The Waterford 3 and Saint Charles Parish Emergency Response Plans include back-up processes to provide warning to affected areas, if required, in the event of the loss of sirens."

The NRC Resident Inspector has been notified.

TECHNICAL SUPPORT CENTER NON-FUNCTIONAL

"Technical Support Center (TSC) Air Conditioning [AC] unit is out of service. Due to expected high temperatures in the upcoming days, there exists the potential for the TSC to become nonfunctional. This could result in a reduction in Emergency Plan Response Capability. The Alternate TSC is available for use in the event of an emergency and would be staffed and activated using existing EP (Emergency Preparedness) procedures and checklists."

The licensee has notified the NRC Resident Inspector.

* * * UPDATE FROM P.C. MOORE TO STEVEN VITTO ON 08/17/2015 AT 1010 [EDT] * * *

"As of 0700 [CDT], 8/17/15, the TSC is fully functional, the HVAC system has been restored to 100 percent capacity.

"NRC Resident Inspector has been notified."

R4DO (HAGAR) has been notified.

PART 21 REPORT - NOTIFICATION OF DEVIATION REGARDING HK CIRCUIT BREAKER PIVOT PIN

The following summary was excerpted from a facsimile received from ABB:

"This letter provides notification of a failure to comply with specifications associated with a pivot pin, part number 193610B00, used in HK circuit breakers. This pin is used as the pivot point for the arcing contacts. Information is provided as specified in 10CFR21 paragraph 21.21(d)(4).

"Notifying individual: Jay Lavrinc, Vice President & General Manager, ABB (Medium Voltage Service), 2300 Mechanicsville Road, Florence, SC 29501, phone number: (843) 413-4727

"Identification of the Subject component: ABB part number 193610B00 pivot pin. This pivot in is used on new legacy HK circuit breakers and during HK breaker refurbishments. The pivot pin is also available as a component item, as part of HK breaker refurbishment kits, and as part of upper terminal contact assemblies.

"Nature of the deviation: During a breaker refurbishment at the ABB Florence facility, it was noted that a pivot pin cracked at the threads during installation. The peening operation performed on the threaded end of the pivot pin caused cracking due to brittle failure. Laboratory testing revealed that this particular pivot pin was made from an incorrect material. This pivot pin was purchased in April of 2015 and parts from this batch were used between 14 April and 28 May of 2015. There have been no field failures reported at this time.

"Corrective actions include:
a. Removed all remaining pivot pins from stock. (Action complete)
b. Contact primary vendor to investigate cause and correct on future orders. (Action Complete)
c. Added material verification to our Critical Characteristic cards for future orders. (Action Complete)
d. Upgrade of ABB's spectrometer to analyze this silicon bronze material on all future shipments. (Action Complete)
e. Obtained and tested, via qualified laboratory, a batch of pivot pins to supply to customers. (Action Complete)
f. Notification of the potential existence of this deviation to affected customers (Action to be completed the week of 10 August 2015)

"Affected Customers: Dominion (Surry Power Station); DTE Energy (Enrico Fermi Power Plant 2); Exelon Corporation (Limerick Generating Station); TVA (Sequoyah Nuclear Plant)

"Recommendations: If the part was installed in a breaker or assembly and the threaded end did not show signs of failure or fracture at installation, it is not considered to be part of the suspect population. ABB recommends that these pivot pins be visually inspected at the next convenient maintenance cycle. If the pivot pin is in their inventory as a component item or in a kit and was shipped in the time interval of the suspect material, it should be returned to ABB for replacement."

AGREEMENT STATE REPORT - LOST TRITIUM TARGET SIGHTS

The following report was received by the State of California via email:

"On August 12, 2015, [the licensee's], Alternate Radiation Safety Officer, contacted the [State of California Radiologic Health Branch] Brea Radioactive Materials office to report lost Tritium [target sight] sources. After receipt at the [licensee] facility, 18 sources were no longer accountable in the inventory process. [The licensee] noted that, sometime between August 6 and August 10, the loss was discovered by one of the [licensee's] authorized users while performing an inventory of sources in the shipment to ensure that the proper number of sources were received. The lost sources were SRB Technologies, Inc. model AR Tritium [target sights] generally licensed sealed sources (these sources do not have serial numbers) with 0.8 Curies of tritium, for a total of 14.4 Curies.

"After the missing sources were discovered, SRB Technologies was contacted to determine the number of sources that were supposed to be contained in the package. When SRB Technologies personnel notified [licensee] that the package contained 36 sources, as listed in the included packing slip, [licensee] personnel conducted a search of the facility to find the sources. When the search did not find the missing sources, it was determined that the missing sources were likely to have been thrown away with the packaging in their trash bin, which had already been emptied on the morning of August 7, 2015. The Irvine facility of Waste Management was contacted to determine if it was possible to search the trash bin, but they were told that was not possible and the trash was most likely to have been dumped in a landfill. Once the investigation into the loss of sources was completed on August 12, 2015, the licensee determined the sources to be lost, most likely in a landfill. After the determination that the source were lost was made, [the licensee] then contacted the [State of California] Brea Office to make the official report."

California 5010 Number: 081215

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.
