Event Notification Report for April 22, 2014

AGREEMENT STATE REPORT - LOST AND FOUND MOISTURE DENSITY GAUGE

The following was received from the State of Arizona via email:

"The Agency [State of Arizona] was informed by the Licensee at approximately 2:45 PM [MDT], April 22, 2014 that at approximately 2:00 PM a worker had lost a Campbell-Pacific Model MC-1, SN MD41007631 moisture density gauge off a pickup truck. The worker forgot to close the tailgate. The gauge contained 10 millicuries of Cesium 137 and 50 millicuries of Americium 241. At approximately 3:15 PM, the Mesa Fire Department reported they had possession of a gauge found on a freeway near the work site.

"A review of the situation confirmed that this was the lost source by the Licensee. The Agency [State of Arizona] has released the gauge to the Licensee for leak testing.

"The NRC, FBI and Governor's Offices are being notified of this event.

"The Agency continues to investigate this event."

First Notice: 14-008

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.

OFFSITE NOTIFICATION DUE TO DECEASED MIGRATORY BIRD FOUND ON PLANT PROPERTY

"Monticello Nuclear Generating Plant personnel discovered the remains of a deceased migratory bird on plant property. The cause of death was not immediately apparent, no work was ongoing in the vicinity at the time the bird was found. Notifications to the Minnesota Department of Natural Resources and the Division of Fish and Wildlife will be made for this discovery. This event is being reported per 10CFR50.72(b)(2)(xi)."

The NRC Resident Inspector will be informed.

AGREEMENT STATE REPORT - RADIOGRAPHY SOURCE HANG-UP

The following was received from the State of Kansas via fax:

"Today [on] 4/22/14, [the] x-ray radiography crew had a source hang-up, at the NCRA plant in McPherson, Kansas, at approximately 0930 CDT. [The] radiography crew performed their operational and emergency procedures very well. A 35 curie Ir-192 source hung up in the source guide tube. [The crew] made the necessary adjustments to their boundaries, kept watch over them, allowed no one to enter, notified [the crew supervisor] and the Kansas RSO. They re-adjusted the crankouts and pulled them to straighten out the cranks and guide tube, and were able to retract the source into the device with one attempt, and were successful. There was no disconnect or anyone exposed to radiation levels above regulatory limits.

"Notification of the incident was given to the plant safety coordinators at the time of the incident, and they remained at distance to avoid exposure, the full time of the incident lasted approximately 10-15 minutes from the initial determination of a stuck source to retraction of the source into the device."

Three monitored IRISNDT staff were onsite and they watched over the boundaries while the retraction was completed. After the incident, all IRISNDT staff read their Instadose film badges and got readings from their personal dosimeters ranging from 1.2 to 3.8 mRem.

Kansas incident # KS140007

AGREEMENT STATE REPORT - LOST TRITIUM EXIT SIGNS

The following information was obtained from the State of New Jersey via facsimile:

"TCNJ [The College of New Jersey] reported the loss of up to 63 radioluminescent exit signs. The signs had been removed from a building slated for demolition and were stored until proper disposal could be arranged. Each Safety Light corporation sign contained between 278 and 851 GBq of H-3. TCNJ was not sure of the actual total of signs possessed by them. They believe that a box containing up to 51 signs was accidentally picked up on 1/8/14 by a contractor removing electronic waste."

EMERGENCY DIESEL GENERATOR INVALID ACTUATION

"This report describes an invalid actuation of the Unit 2, Train A (2-01) Emergency Diesel Generator (EDG) that occurred on April 22, 2014. This report is being made in accordance with 10CFR50.73(a)(2)(iv)(A). 10CFR50.73(a)(1) states, in part, 'In the case of an invalid actuation reported under 10CFR50.73(a)(2)(iv), other than actuation of the Reactor Protection System (RPS) when the reactor is critical, the licensee may, at its option, provide a telephone notification to the NRC Operations Center within 60 days after discovery of the event instead of submitting a written LER.'

"On April 22, 2014, Comanche Peak Nuclear Power Plant Unit 2 was in Mode 5 during the 14th refueling outage. At approximately 0830 CDT, while performing a lockout test on EDG 2-01, the Reactor Operator made a place keeping error that resulted in EDG 2-01 starting and rolling up to approximately 300 RPM. The start signal should have been blocked as part of the test. However, a step was skipped due to a place keeping error and this resulted in an inadvertent start of EDG 2-01 during the performance of a subsequent step.

"The specific train and system that actuated was the Unit 2, Train A, Emergency Diesel Generator. During the inadvertent EDG start the system started and functioned correctly, and the EDG only reached 300 RPM before it was shut down.

"The licensee has notified the NRC Resident Inspector."
