The following was received via facsimile:
"This is to notify the Nuclear Regulatory Commission, in accordance of the provisions of 10 CFR Part 21 of a potential deviation identified by Nutherm International, Inc.
"On June 26, 2012 one M470 Spring Return Kraus and Naimer (K&N) switch (part number CA10 USN892 - 600 FT1 S0C G211 S0 M470/D1A) failed at the Nutherm facility.
"The failed switch was returned to the manufacturer for failure analysis. On July 2, 2012 the manufacturer notified Nutherm that the specific failure mechanism was spring failure on the 'spring return.' The failure was traced to a spring manufacturer supplying the manufacturing facility between November 1, 2011 and June 29, 2012.
"Based on this information, M470 spring return switches manufactured during this time period have the potential for this spring failure.
"Nutherm has determined that the following site has received these switches from Nutherm and is affected: Farley Nuclear Plant."

The following was received via facsimile:
"This written final report is in response to Event/Accession Number ML121910334 reported by Nutherm International, Inc. There were a total of three (3) switches shipped to Southern Nuclear Operating Company, Farley Nuclear Plant affected by this issue. Southern Nuclear Operating Company, Farley Nuclear Plant was notified on July 2, 2012 of this issue and provided with the specific traceability numbers of all units. None of the units had been installed at the time of the notification.
"Southern Nuclear Operating Company returned all three units on July 5, 2012. The units were subsequently destroyed by Nutherm International, Inc.
"Corrective actions have been put in place to prevent recurrence of this issue. Corrective actions include additional testing of spring return switches of this model type."

"At approximately 1615 CDT on June 17, 2013, station personnel identified a potential unanalyzed condition based on the following:
"The 1998 design calculation for the carbon dioxide fire suppression system protecting the Relay Room is in part based on an unverified leakage rate for the enclosure. Recent testing and subsequent calculations have found the room leakage rate is higher than the leakage rate specified in the 1998 design calculation. As such, more carbon dioxide would be required to meet design requirements. The minimum required level for the system storage tank would not currently provide two shots of carbon dioxide (design requirement) to suppress a fire.
"The minimum required quantity in the tank would be sufficient to provide one shot of carbon dioxide to suppress a fire; however, since this doesn't meet the design requirement, a continuous fire watch was initiated."
The licensee notified the NRC Resident Inspector.
* * * RETRACTION ON 7/16/13 AT 1648 EDT FROM MARK LOOSBROCK TO DONG PARK * * *
"Further evaluation determined that the as-found configuration did not meet the minimum design requirements. However, the CO2 concentration was adequate to suppress a fire within the relay and cable spreading room."

The following information was obtained from the State of New Jersey via email:
"At approximately 1:30 p.m. [EDT] on Monday, July 8, 2013, the consulting health physicist for Hopewell Radiology Group called to inform the NJDEP's RMP [New Jersey Department of Environmental Protection Radioactive Materials Program] that a sealed vial source originally containing approximately 209 uCi of Cesium-137 on June 1, 2001, was found to be leaking. The source was manufactured by Eckert & Zeigler and has a serial number of 747-33-46.
"A routine semi-annual leak test of the source revealed the presence of 0.067 uCi of removable contamination, which exceeds the limit of 0.005 uCi.
"The source has been removed from service and is secured at the licensee's location. The licensee is arranging for appropriate disposal." |

On December 20, 2012, a patient was administered microspheres to treat the liver. On July 9, 2013 the administering facility learned that a biopsy identified microspheres in a slow healing gastric ulcer. The facility is assuming that the patient received a dose that exceeded the limits based on the presence of microspheres and the development of a gastric ulcer.
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. |

"At 1600 CDT on Sunday, July 14, 2013, the Dresden Nuclear Power Station (DNPS) Technical Support Center (TSC) emergency ventilation system will be removed from service for planned preventative maintenance activities on the TSC air handling unit and air compressor units. During the maintenance, the TSC ventilation will be shut down. The TSC air filtration fan and dampers will be non-functional, rendering the TSC HVAC accident mode non-functional. This maintenance is scheduled to minimize out of service time. The planned TSC ventilation outage is scheduled to be completed within 48 hours. Contingency plans are in place so that if an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing EP (Emergency Preparedness) procedures and checklists. If radiological or environmental conditions require TSC facility evacuation during ventilation system restoration, the Station Emergency Director will evacuate and relocate the TSC staff in accordance with station procedures.

"Scheduled maintenance of the Technical Support Center (TSC) / Operations Support Center (OSC) HVAC system for replacement of charcoal filters started at 0430 hours [PDT] on 7/16/13 and will last approximately 37 hours (estimated time from equipment tag out back to OPERABLE). During this time the TSC and OSC will not be available for use to support emergency response activities. Established compensatory measures direct Emergency Response Organization (ERO) members normally responding to either of these facilities to respond to alternate locations. No other emergency response facilities are impacted by the scheduled TSC / OSC Facilities HVAC maintenance work.
"This event is being reported as a loss of emergency preparedness capabilities in accordance with 10 CFR 50.72(b)(3)(xiii). The NRC Resident Inspector has been notified. A follow up notification will be made when HVAC maintenance to the TSC / OSC Facilities has been completed and operability of these EP Facilities has been restored." |

"This 60-day optional report as allowed by 10 CFR 50.73(a)(1), is being made under the reporting requirement in 10 CFR 50.73 (a)(2)(iv)(A) to describe an invalid actuation of a specified system, specifically the Nuclear Service Water (RN) system. This event had no impact on public health and safety.
"During work to replace a timer associated with an RN (Nuclear Service Water) level circuit, electrical adapters and jumpers were installed incorrectly, resulting in generation of an Emergency Low Pit Level signal. This resulted in an unplanned actuation for RN to realign its suction source from Lake Wylie (normal source) to the alternate source, the SNSWP (Standby Nuclear Service Water Pond). On 5/28/13, with both units at 100% power, a lo-lo level signal was received for A Train RN Pit, initiating the realignment to the SNSWP for both A and B trains. Prior to this event, both trains of RN were aligned to the SNSWP for maintenance.
"The lo-lo level signal did initiate a start of all available RN Pumps. Associated valves, including RN crossover valve, return header isolation valves and non-essential header isolation valves closed as expected. This separated RN trains A and B. This was a complete actuation for Train A and the system performed as designed for existing plant conditions. This event was entered into the site corrective action program for resolution."
The licensee will notify the NRC Resident Inspector, as well as, the State and local governments. |

The LCO was subsequently exited at 1830 hours when the temperature of SSW trended to below the TS limit.
"Under certain accident conditions the SSW system is required to provide cooling water to the Reactor Building Closed Cooling Water (RBCCW) system heat exchanger. When the inlet temperature to this supplied load exceeds the 75 [degrees] F limit established in the TS, the SSW system is declared inoperable until the temperature trends below this value. This condition existed for approximately 1-1/2 hours and the SSW system was declared operable and the LCO exited. A maximum temperature of 75.3 [degrees] F was recorded during this period.
"The SSW temperature is being closely monitored and trended on a continuous basis.
