| This material event contains a "Less than Cat 3 " level of radioactive material. | Event Text AGREEMENT STATE REPORT - FIXED GAUGE WITH SEALED RADIOACTIVE SOURCE RECOVERED AT A SCRAPYARD
The following information was received from the Ohio Department of Health (ODH) via email:
"A load of scrap metal set off the radiation detectors at a scrapyard in Cleveland, Ohio at approximately 0940 EDT on 8/2/16. A Department of Transportation exemption was issued and the scrap was returned to the supplier, Cleveland Wire, also located in Cleveland. The load was sorted by Cleveland Wire staff and a 'C-arm' fixed gauge was discovered.
"ODH investigators arrived at the Cleveland Wire site on 8/3/16 and surveyed the gauge. Highest readings were determined to be 4 mR/hour on contact at the point where the source would be located inside the device, indicating that a source was present and the shutter was closed. Smear wipes taken indicated no removable contamination present. Further investigation showed that a tag was still affixed to the device, indicating the isotope (Sr-90), activity (70 mCi) and assay date (June, 1976). The radiation readings and identifying information are in keeping with what would be expected upon review of the Sealed Source & Device (SS&D) registration for the device. The device is currently in secure storage on site at Cleveland Wire, awaiting plans for transfer or disposal.
"The ODH investigators at Cleveland Wire also learned that the device had been received from an industrial equipment reseller, HDR Industrial Surplus, located in Euclid, Ohio. Another ODH inspector was dispatched to that location on 8/3/16 to survey the facility, check for additional items that might contain radioactive materials, and to determine if the original owner/consignor could be located. No radiation levels were detected above background at the Euclid location, and no other items containing radioactive materials appeared to be present.
"Research and investigation is ongoing to attempt to determine the owner of the device.

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.

| Event Text AGREEMENT STATE REPORT - DEFECTIVE SHUTTER ON FIXED GAUGE
The following was received from the North Carolina Department of Health and Human Services via email:
"General Licensee discovered a defective shutter on one of its fixed gauges while performing leak tests. The shutter was discovered as being completely removed and the gauge remains in the open (source exposed) position. Per the licensee, during its previous leak test in May 2016, the shutter was intact on the gauge at that time. From the time of the previous leak test to present it is unknown how long the shutter was removed from the gauge. Per the licensee, the gauge is positioned with the radiation exposure pointing downward toward its product line where density measurements are determined.
"Currently, the licensee's operations are continuous and the gauge remains in the open position during operations to support business output.
"Discussions with the licensee were held concerning potential radiation exposures to members of the public and its employees. It was determined that due to the design of the licensee's manufacturing process it would be incredibly difficult for anyone to safely come within the immediate vicinity of the gauge with the defective shutter. An entire shut down of the licensee's manufacturing process would have to occur for anyone to gain any safe method of access to the defective gauge, in which the licensee stated, has not occurred since the most recent leak test when the defective gauge was discovered.
"This in an ongoing investigation and more details will be forthcoming."

| This material event contains a "Less than Cat 3 " level of radioactive material. | Event Text AGREEMENT STATE REPORT - LOST MOISTURE DENSITY GAUGE
The following report was received from the State of Texas via email:
"On August 6, 2016, the Agency [Texas Department of State Health Services] was contacted by the licensee's radiation safety officer (RSO) who reported one of their crews had lost a Troxler model 3440 moisture density gauge. The gauge contains an 8 millicurie cesium-137 and a 40 millicurie americium-241 source. The crew had returned to their office in Dallas and when they went to get the gauge to place it in storage they realized the gauge had been left on the tailgate of the truck and was no longer there. The RSO was notified and both the crew and the RSO drove the 20 mile route used by the technicians returning to the office in an attempt to find the gauge, but the gauge was not located. The RSO stated the cesium source was located in the fully shielded position, but the operating rod was not locked. Local Law Enforcement in the area where the gauge was being used was notified of the lost gauge. The gauge does have a label on it identifying the licensee and listing the licensee's contact number. This number is to an answering service. Additional information will be provided as it is received in accordance with SA-300.
"Local law enforcement has been notified."

The following was received from State of Texas via email:
"On August 10, 2016, the Agency [Texas Department of State Health Services] was notified by the licensee that it had recovered the missing gauge. The licensee's radiation safety officer (RSO) stated they found the gauge listed on Craig's List web site and contacted the seller. The RSO stated they paid the seller a reward and gained custody of the gauge at 1445 hours on August 10, 2016. The RSO stated the gauge was not damaged and the cesium source was still fully shielded. The RSO stated he was sending the gauge to a service company for inspection. Additional information will be provided in accordance with SA-300."

"On August 13, 2016 at 0330 EDT, Watts Bar Nuclear Plant Unit 2 (WBN2) was being stabilized following a pre-planned reactor trip. Both motor driven auxiliary feed water pumps and the turbine driven auxiliary feed water pump (TDAFW pump) were in operation maintaining steam generator water level 6 - 50 percent in accordance with the Reactor Trip Response Procedure.
"At 0333 EDT the TDAFW pump was secured by procedure and steam generator water level lowered to the Low Low Alarm setpoint (17 percent). The trip time delay at 0 percent power is three (3) minutes. At 0336 EDT, the TDAFW pump automatically started with steam generator water levels less than the Low Low alarm setpoint (lowest level reached was 15 percent).
"Steam generator water level was restored to the normal shutdown control band (38 percent).
"Unit 1 remains in Mode 1 at 85 percent.
"Unit 2 is stable in Mode 3 with normal shutdown power alignment. The reactor coolant system is being cooled down to 400 degrees F for a planned maintenance period, with decay heat removal via the Main Condenser Steam dumps and the AFW system.
"This event is being reported pursuant to 10 CFR 50.72(b)(3)(iv)(A).

Prairie Island Unit 1 declared an Unusual Event at 2359 CDT on 8/13/2016 based on Reactor Coolant System (RCS) identified leakage being greater than 25 gpm. The RCS leakage was 40 gpm for three (3) minutes. The RCS leakage was stopped when letdown flow was isolated. Minimum charging flow has been established and Excess Letdown was placed in service. Prairie Island Unit 1 is currently stable and continues to operate at 100 percent power. There was no impact on Prairie Island Unit 2.
"CV-31339 (Letdown Line Containment Isolation Valve) failed closed. VC-26-1 (Regenerative Heat Exchanger Letdown Line Outlet Relief to Pressurizer Relief Tank [PRT]) lifted with 40 gallons per minute to the PRT for three (3) Minutes. Operators entered procedure 1C12.1 AOP3, Loss of Letdown Flow to VCT. Letdown was isolated per 1C12.1 AOP3, relief valve VC-26-1 reseated and leakage to the PRT stopped. Charging flow was reduced to one (1) charging pump at minimum speed (16 GPM). Excess letdown was placed in service to maintain pressurizer level between 32 - 34 percent. The cause for CV-31339 closing has not yet been determined.
"The NRC Resident Inspector has been notified."
