Event Notification Report for June 13, 2016

FITNESS-FOR-DUTY

A non-licensed employee supervisor had a confirmed positive for alcohol during a random fitness-for-duty test. The employee's access to the plant has been denied.

The licensee has notified the NRC Resident Inspector.

ALERT SIRENS FAILED TO ROTATE

"At 1845 CDT on June 13, 2016, TVA Corporate Emergency Preparedness notified the Shift Manager at Browns Ferry Nuclear Plant that eight of the BFN [Browns Ferry Nuclear] Alert & Notification Sirens (19, 39, 55, 59, 60, 61, 69, 95) failed to rotate. The sirens were activated at 0915 CDT. Post sounding siren feedback indicated thirteen sirens that failed to rotate. BFN EP [Emergency Preparedness] Senior Instrument Mechanics were dispatched to inspect the thirteen sirens and determined, through field inspections that only eight sirens would not rotate. The field inspection was completed and communicated to Corporate Emergency Preparedness at 1733 CDT.

"Per NPG-SPP-03.5.1, the affected sirens which were lost affect 25.1 percent of the Emergency Planning Zone (EPZ) population and the sirens are not expected to be returned to service within 24 hours. Per NPG-SPP-03.5.1, a Loss of Alert and Notification System Capability exists when there is an unplanned or planned loss of primary Alert and Notification System (ANS) equipment for greater than one hour resulting in a loss of capability to alert 25 percent or more of the total Emergency Planning Zone (EPZ) population and either the Federal Emergency Management Agency (FEMA) approved backup alerting method cannot be implemented for the area affected by the lost primary ANS equipment OR the primary ANS equipment is not expected to be returned to service within 24 hours.

"TVA Corporate Emergency Preparedness is redirecting a team from Watts Bar Nuclear Plant to commence repairs on Wednesday 6/15/2016.

"This 8 hour notification is being made per the reporting requirements specified by 10 CFR 50.72(b)(3)xiii.

"The NRC Resident Inspector has been notified.

"This event has been entered in the Corrective Action Program."

* * * EVENT RETRACTION FROM MARK MOEBES TO RICHARD SMITH AT 0538 EDT ON 7/08/2016 * * *

"The licensee is retracting this event notification.

"Upon further evaluation using siren modeling software, back-up route alerting was deemed unnecessary since the overlap from neighboring sirens provided the required minimum siren coverage over all populated areas within the EPZ. The TVA siren system provides significant acoustic overlap that is not completely accounted for in the population factors used to initially determine the impacted population for the purposes of reportability. During the event, BFN remained capable of providing adequate siren coverage, and the loss of ANS equipment impacted less than 25 percent of the population within the EPZ. Therefore, this was not a reportable event.

"The NRC Resident Inspector has been notified."

AGREEMENT STATE REPORT - MEDICAL EVENT

"On Monday June 13, 2016, the licensee's radiation safety officer contacted the Agency [Illinois Emergency Management Agency] to advise that a seed localization procedure utilizing a radioactive source was not going to be completed as planned. An I-125 seed had been implanted on June 9, 2016 to mark an area of the breast for subsequent examination and surgical explantation on June 13, 2016. However, the patient experienced a stroke during the interim days and the planned surgery for explantation aborted. Given the patient's condition it was determined that the risk associated with surgery to the patient was greater than the risk associated with not performing the seed retrieval. Initial estimates of the effective whole body dose are 3.7 Rem and dose to the breast 73 Rad. No permanent functional damage to the organ/tissue is expected as a result of the inability to remove the source. If the patient's condition improves and the opportunity arises, the seed may still be explanted at a much later date."

IL Item Number: IL16004

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.

AGREEMENT STATE REPORT - FOUND RADIOACTIVE SCRAP METAL

This was reported from the State of Alabama via facsimile:

"On June 13, 2016, the Radiation Safety Officer for Nucor Steel in Decatur, Alabama notified the Alabama Office of Radiation Control in regards to a piece discovered in scrap metal received via railcar. The piece appears to be a retaining ring approximately the diameter of a dime. The piece is reading over 5,000 mRad/hr at contact using a Ludlum model 15 survey meter. The piece has been secured in a building within the site boundary and away from employees. The licensee is continuing to research where and when the piece arrived onsite. The [Alabama] Office of Radiation Control plans to meet with site personnel on June 16, 2016. As of today, [6/14/16] 1235 CDT, this incident remains open until further investigation can be completed."

Alabama Incident # 16-23

* * * UPDATE AT 1131 EDT ON 06/17/16 FROM MYRON K. RILEY TO S. SANDIN VIA FAX * * *

"On June 16, 2016, [representatives from the Alabama] Office of Radiation Control visited the site to conduct measurements and spectrum analysis. The retaining ring read 13.5 mR/hr at contact, 3.6 mR/hr at one foot, and 0.5 mR/hr at three feet with a Fluke 451P #2644, calibrated 12/10/15. Spectrum analysis using a Thermo IdentiFINDER revealed the isotope to be Co-56. This was confirmed through the Joint Analysis Center Collaborative Information System.

"As of today [06/17/16], 1025 CDT, this incident remains open until disposal options have been completed."
