AUTOMATIC REACTOR TRIP DUE TO HIGH REACTOR COOLANT SYSTEM PRESSURIZER PRESSURE
"At 0823 hours on August 8, 2012, Arkansas Nuclear One, Unit 2 (ANO-2) experienced an automatic reactor trip. The reactor automatically tripped due to High Reactor Coolant System Pressurizer Pressure that was caused by a Main Turbine trip due to high condenser back pressure from a degraded vacuum condition. The Reactor Protection System (RPS) performed as designed in response to the High Reactor Coolant System Pressurizer Pressure condition resulting in automatic shutdown of the reactor from approximately 100 percent power. All Control Element Assemblies (CEAs) fully inserted on the trip. The Emergency Feedwater Actuation System (EFAS) actuated for the 'A' Steam Generator only due to level trending slightly below the setpoint. The plant has transitioned to supplying the steam generators using the Auxiliary Feedwater (AFW) system.
"The unit is currently in Mode 3 and implementing the transient response process. The investigation into the cause of the trip is ongoing and the local NRC Resident Inspectors have been notified."
The unit is in a normal electrical lineup, and the decay heat is being removed by the main condenser via the turbine bypass valves.
The State Department of Health was notified and ANO-2 will be issuing a press release.

LOSS OF EMERGENCY ASSESSMENT CAPABILITY
"At 1350 PDT on 08-08-2012, during the performance of an annual surveillance, power supply ARM-E/S-603A was discovered to have out of tolerance voltage readings. ARM-E/S-603A was declared non-functional. This resulted in a loss of the ability to monitor and quantify radiological conditions in multiple areas of the reactor building, due to the loss of ARM-RIS-1 through 10 (Area Radiation Monitor Radiation Indicating Switches 1 through 10).
"The loss of ability to monitor and quantify radiological conditions in multiple areas of the reactor building represents a major loss of emergency assessment capability per 10 CFR 50.72(b)(3)(xiii). As directed by station procedures, compensatory measures have been enacted to have Health Physics personnel tour the affected areas once per shift to document and trend the radiological conditions. ARM-RIS-1 and 4 thru 10 are used for EAL determinations.
"ARM-E/S-603A was returned to service at 1524 PDT on 08/08/2012."
The licensee has notified the NRC Resident Inspector.

AGREEMENT STATE REPORT - IMPROPER DISPOSAL OF TRITIUM EXIT SIGNS
The following information was received from the State of New Hampshire:
"On August 8, 2012, a [Bed Bath and Beyond Vice President] called to report the loss of seventeen tritium exit signs. After taking the signs down, they were stored for Shaw Environmental to package and ship them for disposal. While being stored, they were mistakenly taken by another contractor as part of the waste from light bulb removal. This removal was viewed on videotape after Shaw Environmental reported that the box of signs was missing from the storage area.
"[The Bed Bath and Beyond VP] contacted RL Carriers (the removal contractor) to find out where they send the waste for disposal. The location was Waste Management in South Carolina. [The Bed Bath and Beyond VP] contacted Waste Management and was told that they had not received any exit signs but if they had, they would have sent them to Synergy Recycling in North Carolina. When contacted, Synergy Recycling stated that they had not received any exit signs.
"The serial numbers for the 17 Tritium Exit Signs that cannot be located are listed below. The Manufacturer is Safety Light, model SLK-60.
301364 - 301367
301370 - 301376
301381
303792
303794 - 303797"
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.
