| This material event contains a "Category 3 " level of radioactive material. | Event Text AGREEMENT STATE REPORT - IRIDIUM 192 SOURCE LOST DURING SHIPMENT
The following was received from Florida via email:
"On 2 June 2015, an Ir-192 source was shipped via common carrier from Sand Lake Cancer Center in Orlando, Florida to Alpha-Omega Services [AOS] in Vinton, Louisiana. The common carrier states on the travel history that the source was unable to be shipped and was returning to the shipper. There is no date or time for the actual return, and no signature on file (as required). A representative from Elekta reported the 4.7Ci Ir-192 source missing on 17 February 2016 after receiving the information from Sand Lake. Sand Lake and AOS have been in contact between themselves and the common carrier and were unable to locate the source. [The Elekta representative] has already reported this incident to Georgia and is currently trying to get in touch with the common carrier RSO."
Florida incident #: FL16-032
* * * UPDATE PROVIDED BY KELLIE ANDERSON TO JEFF ROTTON AT 1136 EST ON 02/19/2016 * * *
The following information was provided via email:
Alpha-Omega Services reported to the State of Florida that the source has been located and it is in the Alpha-Omega Services offices in Vinton, LA where the source was being shipped to originally. I seems that it was an administrative error that caused the source to be reported as missing. The State of Florida considers incident # FL16-032 to be closed.
Notified the R1DO (Dentel), R4DO (Vasquez), and NMSS Events Notification Group via email.
THIS MATERIAL EVENT CONTAINS A "CATEGORY 3" LEVEL OF RADIOACTIVE MATERIAL
Category 3 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for some hours. It could possibly - although it is unlikely - be fatal to be close to this amount of unshielded radioactive material for a period of days to weeks. These sources are typically used in practices such as fixed industrial gauges involving high activity sources (for example: level gauges, dredger gauges, conveyor gauges and spinning pipe gauges) and well logging.

"On January 6, 2016. at approximately 1514 EST, with Fermi 2 in Mode 1 operating at 100 percent reactor thermal power, the East and West Turbine Bypass Valves (TBVs) automatically opened for 3 minutes and 32 seconds in response to the number one High Pressure Turbine Stop Valve (TSV) drifting from full open to 25% open. Reactor power was subsequently lowered to 91.0 percent reactor thermal power and the bypass valves closed.
"Per Technical Specification Bases 3.3.1.1, TBVs must remain shut while reactor thermal power is at or above 29.5 percent to consider the TSV closure and Turbine Control Valve (TCV) fast closure Reactor Protection System (RPS) functions operable. The condition was recognized at the time of the event and the RPS functions were not declared inoperable since the functions were verified to remain enabled.
"Since the RPS functions were not declared inoperable, Fermi 2 did not report this event within 8 hours of occurrence. However, after further evaluation, it was determined that this event met the reporting criterion. Accordingly, this event is being reported pursuant to 10 CFR 50.72(b)(3)(v)(A).
"The licensee informed the NRC Resident Inspector."
The cause of the High Pressure Turbine Stop Valve drifting was due to an actuator malfunction that has since been corrected.
This event was determined to be reportable at 1200 EST on 02/24/16. See EN #51756 for a similar event that occurred on 02/21/16. |

"On February 21, 2015, at approximately 0030 EST, with Fermi 2 in Mode 1 operating at 100 percent reactor thermal power, the West Turbine Bypass Valve (TBV) automatically opened in response to the number two High Pressure Turbine Stop Valve (TSV) cycling from full open to closed and then to 22 percent open. Reactor power was subsequently lowered to 91.5 percent reactor thermal power and the bypass valve closed.
"Per Technical Specification Bases 3.3.1.1, TBVs must remain shut while reactor thermal power is at or above 29.5 percent to consider the TSV closure and Turbine Control Valve (TCV) fast closure Reactor Protection System (RPS) functions operable. The condition was recognized at the time of the event and the RPS functions were declared inoperable. The Limiting Condition for Operation was exited at 0031 EST following TBV closure.
"Since the RPS functions were verified to remain enabled, Fermi 2 did not report this event within 8 hours of occurrence. However, this event was subsequently determined to meet the reporting criterion and is being reported pursuant to 10 CFR 50.72(b)(3)(v)(A).
"The licensee informed the NRC Resident Inspector."
The cause of the High Pressure Turbine Stop Valve cycling was due to a communication card failure that has since been corrected.
This event was determined to be reportable at 1200 EST on 02/24/16. See EN #51755 for a similar event that occurred on 01/06/16. | |
