AGREEMENT STATE REPORT - SOURCE DISCONNECT

The following was received from the State of Minnesota via email:

"At approximately 0815 CDT on Friday, 10/21/16, radiographers for Midwest Industrial X-Ray experienced a source disconnect while working on a project for Excel. The project was taking place outside of Waverly, MN, in a rural area. A 34 Ci source (serial number XF2112, model G60) of Ir-192 experienced a disconnect from a SPEC 150 exposure device. The RSO for Midwest Industrial X-Ray, was dispatched to the site and arrived at 1345 CDT on 10/21. Source retrieval was completed by 1445 CDT. Exposures were checked on all involved, with a maximum exposure of 3 mR. Midwest Industrial X-Ray is performing an analysis to determine the cause of the disconnect and will submit a written report within 30 days. More information from the Minnesota Department of Health is forthcoming."

AGREEMENT STATE REPORT - NUCLEAR GAUGE STUCK SHUTTER

The following was received from the State of Texas via email:

"On October 25, 2016, the Agency [Texas Department of State Health Services] was notified by the licensee that while preparing to leak test a VEGA Americas, Inc. model SH-F1 nuclear gauge the shutter on the gauge could not be fully closed. Open is the normal operating position of this gauge. The gauge contains a 60 millicurie (original activity) cesium-137 source. The gauge is on the third floor of a vessel and does not present a exposure hazard to workers or members of the general public. The licensee has contacted a service provider to repair the gauge. Additional information will be provided as it is received in accordance with SA-300."

SOURCE HOLDER STUCK SHUTTER

"At approximately 0700 EDT, October 25, 2016, the RSO [Radiation Safety Officer] and Assistant RSO attempted to open the shutter on source holder 10071961 (Hemlock identifier), while preforming routine maintenance. The shutter operation failed, the shutter is stuck in the closed position. There were no exposures as a result of the failed shutter operation. Operating the shutter was part of a routine preventative maintenance plan. The process is currently shut down, therefore this incident caused no loss of production. The source holder is located on site. Hemlock Semiconductor Operations is in contact with Vega Americas, the manufacturer."

SUPPLEMENTAL COOLING INOPERABLE DURING MOVEMENT OF DRY CASK STORAGE HI-TRACK TRANSFER CASK

This 24 hour report is being made as per 10CFR72.75.

"On October 31, 2016, at 1100 [CDT], the Supplemental Cooling System was secured to the Dry Cask Storage Hi-Track Transfer cask, as allowed by Dry Fuel Storage T.S. 3.1.4, in preparation for moving the Hi-Track transfer cask. At approximately 1500, after moving the Hi-Track into position for downloading including securing the cleats to the mating device, the next step in the procedure was to lower the Hi-Track. When lowering the Hi-Track, a crane overload condition occurred. With the crane, attached the Supplemental Cooling System can not be operated and has remained secured. The Supplemental Cooling System is classified as 'Important to Safety Category B' and is required to be utilized, as necessary, to maintain the peak fuel cladding temperature below the allowed limits. T.S. 3.1.4 allows the Supplemental cooling system to be secured for up to 7 hours during the Hi-Track transfer process and then followed by a 7 day allowed outage time. This is being reported based on 10CFR72.75 which states in part that a 24 hour Non-emergency notification is required if; 'An event in which important to safety equipment is disabled or fails to function as designed'.

"The Hi-Track is presently in a safe condition with supplemental cooling still secured."

The licensee has notified the NRC Resident Inspector.

ALERT DECLARED AT FARLEY UNIT 1 DUE TO AMMONIA EXCEEDING IDLH LEVELS IN THE AUXILIARY BUILDING

"At 1743 CDT on 11/1/16, readings were obtained that indicated ammonia above IDLH [Immediately Dangerous to Life and Health] values in the Unit 1 Auxiliary Building and an Alert was declared by the Emergency Director. The plant is stable with Unit 1 at 2% power. Unit 2 is at 100% power [and stable]. The site is currently investigating to determine the source and ventilate the area."

The licensee has informed the NRC Resident Inspector.

* * * UPDATE FROM BLAKE MITCHELL TO STEVEN VITTO ON 11/02/2016 AT 0443 EDT * * *

"The following is the Emergency Preparedness 8-hour report for the Plant Farley ALERT declaration. An ALERT was declared at 1743 CDT on November 1, 2016, based on Emergency Action Level (EAL) HA3 (Release of toxic, asphyxiant, or flammable gases within vital areas which jeopardizes operation of systems required to maintain safe operations or establish or maintain safe shutdown) due to an ammonia discharge into the Auxiliary Building. Farley Unit 1 was in Mode 2 at 2 percent power and Unit 2 was in Mode 1 at 100 percent power throughout the event.

"Actions completed during and leading up to termination from the event included walkdown of the area to locate the ammonia source, and isolating the ammonia source while atmospheric monitoring was performed in all affected and adjacent areas. Installation of additional ventilation fans was completed. This event has been entered into the Farley Corrective Action Program under Condition Report 10293519 (Ammonia levels in 100 Feet Radside).

"A review of the Alert classification has determined that the classification was timely and accurate. All required notifications were completed accurately and in a timely manner. The ERO [Emergency Response Organization] notification system functioned as expected and all emergency response facilities were activated in a timely manner. There were no missing or injured personnel during the event. There is no evidence of tampering or sabotage of plant equipment leading to this event."

At 2202 CDT on 11/1/2016, the ammonia source was identified as Valve N1P20V913. At 2228 CDT, the ammonia source was isolated. Final assessment of the Auxiliary Building showed that the ammonia levels were less than 5 ppm. It was determined that a deficiency in the valve component was the cause of the ammonia leak.

The Alert was terminated on 11/1/2016 at 2340 CDT.

The Licensee has notified the NRC Resident Inspector.
