60-DAY OPTIONAL TELEPHONIC NOTIFICATION OF INVALID SPECIFIED SYSTEM ACTUATION
"In accordance with 10CFR50.73(a)(2)(iv)(A), this telephone notification reports an invalid actuation of the Unit 2 train B (2B) Emergency Diesel Generator (DG) undervoltage auxiliary relay on October 19, 2012 at 2324 hours. At the time of he event, Unit 2 was in Mode 6, Refueling. The 2B DG was undergoing the completion of a monthly surveillance and was operating in parallel with the offsite power, when the 2B DG changed from the test mode to the emergency mode. The offsite feed to the bus (ACB 2422) tripped, and the 2B DG load increased to carry the bus. Proper operation of the 2B DG was verified, and expected train equipment loaded and functioned successfully. The potential cause is attributed to a spurious actuation of the undervoltage auxiliary relay. This condition was entered into the corrective action program.
"The licensee notified the NRC Resident Inspector and the Illinois Emergency Management Agency Resident Inspector."

AGREEMENT STATE REPORT- CONTAMINATION EVENT
The following information was received by facsimile:
"DRH [Tennessee Division of Radiological Health] was notified on 10/19/12 by the licensee that preliminary analytical results of a 30-gallon waste container of tritium contaminated waste oil and absorbents indicate approximately 8,600 curies of tritium. The container was manifested by the generator (SRS) [Savannah River Site] as containing 14.9 curies. Post sampling of this container, DSSI [Diversified Scientific Services, Inc.] had a controlled but elevated level of tritium contamination in the process room; this room is under negative ventilation. The room has been decontaminated back to normal processing levels. Contents of the container have been overpacked and placed in a safe state, [and] not a source of tritium contamination to the air or surface."
