| This material event contains a "Less than Cat 3 " level of radioactive material. | Event Text LOST TRITIUM EXIT SIGN
A tritium exit sign was mistakenly placed in general waste by an employee who was replacing the sign on 10/11/15. The employee reported the mistake on 10/13/15 and the licensee initiated attempts to locate the sign. The sign was determined to have been placed in a general waste container which had already been collected. The manufacture date of the sign was 2/2009 and at the time of the disposal the source was intact. The lost source material (0.426 TBq of Tritium as of 2/2009) is considered unrecoverable.
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.

"A planned surveillance was started on the Quad Cities Station Technical Support Center (TSC) ventilation air filtration system. The surveillance measures the flow rate through the air filtration unit and verifies the TSC is pressurized to ensure habitability requirements. The flow rate obtained was high, outside of acceptance criteria, and the surveillance was stopped pending resolution.
"If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing procedures. If TSC evacuation is warranted due to radiological conditions, the facility will be relocated in accordance with existing procedures.
"This event is reportable per 10CFR50.72(b)(3)(xiii) since the air filtration unit affects an emergency response facility.
"The NRC Resident Inspector has been notified."

"At 0348 CDT, while Point Beach Unit 2 was performing outage activities, it experienced a Main Power Transformer lockout and associated loss of busses (2A-01, 2A-02, 2B-01 and 2B-02). The loss of the two non-vital 4160 V buses resulted in actuation of the Unit 2 undervoltage logic which resulted in actuation of the Auxiliary Feedwater System. The Auxiliary Feedwater System functioned normally upon actuation.
"This condition was determined to be reportable per 10CFR50.72(b)(3)(iv)(A)(6), PWR auxiliary or emergency feedwater system actuation.
"This event did not affect the operating Unit 1.

| Event Text PART 21 REPORT - DEFECT ASSOCIATED WITH PRESSURIZER INSTRUMENTATION PIPING PENETRATION IN MODULE FOR VOGTLE UNIT 3
The following information was excerpted from an email received from CB&I:
"This letter provides a report in accordance with 10 CFR 21.21 pertaining to the identification of a defect associated with a structural module piping penetration for the Vogtle Unit 3 AP1000 project. The defect is associated with a Pressurizer instrumentation piping penetration in structural module CA01 for Vogtle Unit 3.
"This condition was previously identified by interim report letters dated July 1, 2015, and September 2, 2015.
"The discovery date of these deviations is based on the date of the associated CB&I Power Inspection Report (IR). That IR was initiated on May 5, 2015. Interim Part 21 reports dated July 1, 2015, and September 2, 2015, were submitted to the NRC that state the evaluation of this condition was expected to be completed by October 30, 2015. The interim reports were identified as Accession Nos. ML15254A043 and ML15201A130, and Log Nos. 2015-50-01 and 2015-50-00, on the NRC 'Part 21 Reports' website.
