CONTROL ROOM AREA RADIATION MONITOR FAILED LOW
"At 0950 CST on December 3, 2014, R-1 Control Room Area Radiation Monitor failed low and was taken out of service. This monitor has no redundant monitor that will allow timely classification of two Emergency Action Levels (EALs) - NUE (Notification of Unusual Event) and Alert classifications - when out of service. This results in a Loss of Emergency Assessment Capability while R-1 is out of service. This is a reportable condition in accordance with 10 CFR 50.72(b)(3)(xiii).
"Control Room readings were normal as evidenced on R-1 prior to its failure. Compensatory measures have been established with a Portable Area Monitor installed in the Control Room adjacent to R-1. Corrective maintenance is in progress and will continue until the monitor is returned to service.
"The health and safety of the public was not affected by this issue.
"The licensee has notified the NRC Resident Inspector."

AUTOMATIC REACTOR TRIP DUE TO TURBINE TRIP
"An unexpected main turbine trip causing a reactor trip occurred on 12/03/2014 [at 0022 CST] with the plant operating in Mode 1 at 100 percent power. As part of the plant design, an expected, valid actuation of the Auxiliary Feedwater System occurred in response to the reactor trip. As part of the Auxiliary Feedwater actuation, the 'B' Motor Driven Auxiliary Feedwater Pump to 'D' Steam Generator throttle valve did not throttle as expected and was manually isolated. All other systems functioned normally in response to the plant conditions. The plant is currently stable in Mode 3 at 0 percent power. Safety related buses are receiving normal off-site power and the grid is currently stable.
"The NRC Resident Inspector was notified."
All control rods fully inserted on the reactor trip. Steam generator levels are being maintained by the AFW system and decay heat is being removed by the main condenser. No primary or secondary safety relief valves lifted during the transient.

LOST STATIC ELIMINATOR
"Dassault Falcon Jet Wilmington Corp. has lost a leased piece of equipment that contains radioactive materials. The tool in question is an air blow gun leased from NRD, LLC. The blow gun model number is P-2021-1000, Serial number A2JT781 and was on lease number 055641 shipped on 12/03/2013. The blow gun [contains] 1.7 mCi (61 MBq) [of Po-210].
"The tool was used to remove static from aircraft interior windows and also to remove static from interior wood paneling between decorative finish coats. It was used primarily in the cabinet department of the company for the purposes described above. The tool was believed to last be used in June of 2014.
"Since discovering the tool was lost, every effort has been made to locate it by posting lost tool messages throughout the company and searching all tool storage locations and employee tool boxes. To prevent this from happening again, the company has placed tools like this into our inventory tool control program where employees will be required to sign out tools and return them after jobs are complete."
The tool was in use at the company's New Castle, DE facility.
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.
