"This is a non-emergency eight hour notification in accordance with 10 CFR 50.72(b)(3)(iv)(A), for an automatic actuation of the 3A Emergency Diesel Generator (EDG).
"On 11/18/15 at approximately 0326 [EST] a loss of power was experienced on the 3A 4KV Bus. The redundant 3B 4KV bus did not experience a loss of power. All systems operated as expected following the loss of power with the 3A EDG automatically sequencing onto the 3A 4KV bus and the load sequencer loading as designed. At the time of the actuation, Unit 3 was in a refueling outage in MODE 5. Investigation into the cause of the loss of power is in progress. There was no impact on Unit 4 operation during this time."
The NRC Resident Inspector has been informed.

The licensee is retracting the original notification of a valid actuation and has re-categorized this as a 60-day optional report based on the following:
"This 60-day telephone notification is being made under the reporting requirements specified by 10 CFR 50.73(a)(2)(iv)(A) and 10 CFR 50.73(a)(1) to describe an invalid actuation of the 3A EDG. The 3A EDG start resulted from an unexpected actuation of the 3A load sequencer during setup activities for the 3A Engineered Safeguards Integrated Test (ESIT) loss of offsite power (LOOP) sequence.
"On November 18, 2015, at approximately 0330 EST with Unit 3 in Mode 5 during a refueling outage, an unexpected LOOP occurred on the 3A 4160 V bus. At the time, an Instrument and Control (I&C) specialist was working in sequencer cabinet 3C23A verifying proper placement of flags in preparation for the installation of a local test switch that would be used to initiate the 3A ESIT LOOP signal. The 3A EDG started and functioned as designed. Initial troubleshooting determined that there were no actual plant conditions or parameters (e.g., undervoltage, degraded voltage, manual initiation) involved in the actuation.
"The root cause investigation revealed that individuals working in the room near the open cabinet did not have their mobile phones in airplane mode as required and two computer tablets being used adjacent to the sequencer cabinet were not in airplane mode as required prior to entering the 3A sequencer room. The cause of the actuation was determined to be an unintended human interaction in the form of electromagnetic or radio frequency interference at the proximity of the 3C23A cabinet.
"The licensee notified the NRC Resident Inspector."

The following information was provided by the State of Texas via email:
"On January 12, 2016, the Agency [Texas Department of State Health Services] received notice that on January 11, 2016, a radiography source could not be retracted to the shielded position. The camera was an 880D with a 99.8 curie Iridium-192 source. An extension to the guide tube had not been connected, and the drive cable slipped the gears of the crank assembly. The drive cable and crank assembly were reassembled and the source was returned to the shielded position. No overexposures resulted from this event. Additional information will be provided as it is received in accordance with SA-300."

| Event Text MEDICAL EVENT - PATIENT RECEIVED DOSE GREATER THAN PRESCRIBED
In preparation for lymphoscintigraphy, a patient was injected with 2.4 mCi of unfiltered technetium sulfur colloid (Tc-99) instead of the prescribed dose of 0.5 to 1.0 mCi.
The Radiation Safety Officer and Hospital Medical Physicist were notified. The patient's primary physician was also notified. No adverse effects to the patient are expected.
This event was caused by the administering technologist's failure to double check the dose given to the patient. The technologist has been counseled.
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. |

"It was discovered on 1/18/16, that an accumulation of uranium oxide existed that indicated a degradation of an IROFS [Item Relied On For Safety] in the dry scrap recycle furnace off-gas system. Approximately 42 kg of uranium oxide powder was removed from the favorable geometry off-gas dropout. The degraded IROFS resulted in a failure to meet performance requirements in the event of a fire. The dry scrap recycle operation had been shut down on 1/14/16 and was not in operation at the time.
"Additional controls on combustibles, geometry and moderation remained intact and at no time was an unsafe condition present.
"Additional corrective actions, extent of condition, and extent of cause are being investigated.
"This event is being communicated to meet the reporting requirements of 10CFR70, Appendix A(b)(2)."

"On January 19, 2016, while reviewing outage data, plant staff recognized that anomalous data collected in October, 2015, for the 21 Auxiliary Feed Pump time response loop resulted in an unanalyzed condition. Preliminary investigation has revealed that the condition most likely existed since April 20, 2015, when maintenance activities were performed on the auxiliary feedwater pump discharge pressure transmitter. Consequently, there were multiple instances when one of the other auxiliary feedwater pumps was removed from service, thus creating a condition which did not meet the accident analysis assumptions for auxiliary feedwater flow initial response.
"This event is being reported under the requirements of 10 CFR 50.72(b)(3)(ii)(B) as 'the nuclear power plant being in an unanalyzed condition that significantly degrades plant safety.' This condition was corrected on November 20, 2015."
The auxiliary feedwater pump discharge pressure transmitter instrument isolation valve was inadvertently left closed after the April 20, 2015 maintenance.
The licensee has notified the NRC Resident Inspector and will notify the State of New Jersey, State of Delaware, and the local township. |

"At 0400 CST on Wednesday, January 20, 2016, the Dresden Nuclear Power Station (DNPS) Technical Support Center (TSC) emergency ventilation system will be removed from service for planned maintenance activities. 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 in approximately 43 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 Emergency Planning (EP) procedures and checklists. If radiological or environmental conditions require TSC facility evacuation during ventilation system restoration; the Station Emergency Director will relocate the TSC staff in accordance with station procedures.
"The NRC Resident Inspector has been notified." | |
