AGREEMENT STATE REPORT - UNCONTROLLED CONTAMINATION EVENT

On April 13, 2010, a student at the Georgia Institute of Technology (the licensee), under the supervision of an authorized user, was conducting an electroplating experiment, using Ni-63, under a fume hood in one of the licensee's RAM (Radioactive Material) rooms. During the experiment, the student noticed fumes outside the hood and ceased the experiment. She took a swipe outside the hood and found no contamination.

On April 14, the licensee's Radiation Safety Officer took swipes of the room and found 22,000 DPM of contamination on the fume hood lip, 11,000 DPM on the RAM room floor, 1,200 DPM on a public hallway floor outside the RAM room, and contamination in an adjacent RAM room. All areas have been cordoned off to control access and cleanup is in progress.

It is unknown whether the student had any uptake, was overexposed, or was contaminated during the event.

AGREEMENT STATE REPORT - LOST BRACHYTHERAPY SEEDS

The following information was received from the State of Florida Bureau of Radiation Control via facsimile:

"Licensee discovered 51 I-125 brachytherapy seeds missing on 13 April 2010. Initial notification to the state was on 16 April 2010, after working hours, to the [State of Florida] duty officer. A search of the premises and outside garbage containers was performed [with negative results]. The search is still on going. Investigation [of this incident has been] assigned to [the State of Florida Bureau of Radiation Control] Miami Office."

Florida Incident #: FL10-056

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.

HIGH FAILURE RATE OF NORMALLY ENERGIZED ELECTRO-PNEUMATIC TIME DELAY RELAYS

The following was received via facsimile:

"Waterford 3 has observed a higher than expected failure rate of normally energized Tyco model E7024PB electro-pneumatic time delay relays produced since 2007. Seven of the eight failures were observed on 2007 or newer date code relays and one was observed on a 2004 date code relay. Waterford 3 had 33 Tyco model E7024PB time delay relays installed in the plant. The Agastat E7000 series timing relay consists of two basic operating types, On-Delay and Off-Delay. The On-Delay models provide a delay period of contact re-positioning on energization and no time delay upon de-energization. The Off-Delay models provide a delay period of contact re-positioning on de-energization and no time delay upon energization. These relays may be ordered with various electrical characteristics suitable for use specific to each application. The early-in-life failures have been observed on Tyco model E7024PB relays designed as an Off-Delay, 4 pole double throw, 125 VDC operating coil, with a time delay range of 0.5 to 5 seconds.

"All failed relays were replaced. Post failure bench testing at Waterford 3, Tyco, or independent Failure Analysis has not consistently repeated the failures."

See EN #44684 for Part 21 reported by Tyco Electronics.

Event Text

ANTICIPATED LOSS OF RADIOACTIVE MATERIAL

The licensee reported that two cementing densometers were aboard the Deep Water Horizon Oil Rig when the oil rig caught fire on the evening of April 20, 2010. The oil rig is located in Federal waters in the Gulf of Mexico (Mississippi Canyon Block 252). At the time of the report, the oil rig was sinking in 4000 feet of water.

The two gauges on the oil rig were as follows:
1. Device 10SD, Device S/N: V32785, Source S/N: DA071, Isotope Products Model No. A-3906, Isotope: Cs-137, Current Activity: 8.3 mCi
2. Device 10SD, Device S/N: W25980, Source S/N: XA923, Gammatron Model No. GTGHP, Isotope: Cs-137, Current Activity: 8.2 mCi

When brought onto the oil rig, both devices were high integrity sources inside a tungsten cavity, and further contained in steel. The licensee had no information whether or not the sources were compromised as a result of oil rig fire and sinking.

Based on the depth of the water where the oil rig is sinking, the licensee does not anticipate that the devices will be recoverable.

The licensee notified the Region IV office of the incident.

This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore, it is being categorized as a less than Category 3 source

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.
