TEXAS AGREEMENT STATE REPORT - UNABLE TO RETRACT RADIOGRAPHY CAMERA SOURCE

The following information was obtained from the State of Texas via email:

"On February 5, 2014, the Agency [Texas Department of Health] received notice that on February 3, 2014, the licensee was unable to retract an 84.5 curie iridium-192 source. The camera and guide tube had fallen from a 22 inch pipe while in use. This caused damage to the guide tube near the camera. The source was retrieved according to license conditions. The retrieval employee received 9 millirem from the retrieval. No member of the public was exposed at rates above limit. The damaged equipment was retired from service and will be replaced. The camera was an INC IR-100 with serial number 7231 and the source had serial number 11337C. Additional information will be provided when it is received in accordance with SA-300."

AGREEMENT STATE REPORT - MALFUNCTIONING SOURCE SHUTTER FAILED TO CLOSE

The following information was received via facsimile from the State of Nebraska:

"The Nebraska Department of Health and Human Services was notified by a representative of the Omaha Public Power District that a Kay Ray fixed gauge Model Number 7080 source shutter failed to close. The device contains approximately 25.5 millicuries of Cesium-137. The gauge is mounted between two fly ash hoppers approximately 20 feet off of the floor. The source closure mechanism on the gauge is connected to a handle located at floor level by a flexible cable. The closure cable is secured so that when the floor handle is operated, the control cable slides inside of the sheath opening/closing the shutter. The shutter closure cable became loose where the sheath attaches to the source closure mechanism which prevented the shutter from closing. The licensee disconnected the lower part from the cable and the on/off handle. By holding on to the lower part of the sheath and sliding the internal cable, the licensee was able to close the shutter. No personnel were exposed to radiation during this event."

AGREEMENT STATE REPORT - TROXLER GAUGE STOLEN FROM TRUCK AT RESIDENCE

The State of Florida was notified at 0630 EST on 2/6/14, that the cab of a gauge user's truck was broken into and the case containing a Troxler Moisture-Density Gauge was stolen overnight at the gauge user's residence located in West Palm Beach, FL. The gauge, a model 3440, was properly stowed and locked in its case.

This gauge contained 5.7 mCi of Cs-137, and 39.1 mCi of Am-241:Be.

Local Law Enforcement is on-scene conducting an investigation.

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.

60 DAY OPTIONAL TELEPHONE NOTIFICATION OF INVALID PCIS SYSTEM ACTUATION


"This notification is being made in accordance with 10 CFR 50.73 (a)(2)(iv)(A) to provide information pertaining to an invalid Primary Containment Isolation System (PCIS) Group 3 actuation signal that affected containment valves in more than one system.

"On 12/15/2013, with the reactor at 100% power, invalid PCIS Group 3 actuation occurred from a momentary spike of the 'B' Refuel Floor radiation monitor which reached the instrument's high radiation trip set point. A radiation protection technician was dispatched to the refuel floor and dose rates in the vicinity of the 'B' radiation monitor detector were verified to be normal and below the alarm set points. The radiation monitor was verified to be indicating normal expected radiation levels. The detector and trip unit were replaced, a functional check and calibration of the radiation monitor was completed satisfactory and the instrument channel was returned to service. The issue has been entered into the station's corrective action program.

"Both trains of Standby Gas Treatment System started as designed and Reactor Building ventilation isolated as a result of the invalid PCIS actuation.

"The PCIS functioned successfully providing a complete Group 3 isolation. The PCIS Group 3 isolation involves the following systems:

"Drywell and Suppression Chamber Air and Vent: V16-19-6, 6A, 6B, 7, 7A, 7B, 8, 9, 10, 23
Containment Makeup: V-16-20-20, 22A, 22B
Containment Air Sampling: VG-23, 26, V109-76A, 76B
Containment Air Compressor Suction: V72-38A, 38B
Containment Air Dilution: VG-9A, 9B, 22A, 22B, NG-11A, 11B, 12A, 12B, 13A, 13B

"Since no actual high radiation condition existed which required the PCIS Group 3 isolation, and the actuation was not in response to actual plant conditions satisfying the requirements for isolation, this event has been classified as an invalid actuation.

"This event did not result in any adverse impact to the health and safety of the public.

"In accordance with 10 CFR 50.73(a)(1) a telephone notification is being made instead of submitting a written Licensee Event Report. The licensee has notified the NRC Resident Inspector."
