AGREEMENT STATE REPORT - TWO NUCLEAR GAUGES FOUND AT METAL RECYCLING FACILITY

The following report was received from the State of Colorado Radioactive Material Unit via facsimile:

"This memo is to serve as a preliminary report for an incident concerning fixed nuclear gauges which were discovered at a Colorado scrap yard which is not licensed for that type of material. The Department [State of Colorado] was notified on December 28, 2011 that two gauges were identified at Rocky Mountain Recycling in Commerce City, Colorado. The initial notification indicated that they were both TN 5100 gauges [subsequently determined to be TN 5200 gauges] with an original activity of 20 mCi in 1986.

"Rocky Mountain Recycling currently has a Colorado provisional radioactive materials license (Colo. 9016-01) and is licensed for six sections of scrap pipe which are contaminated with NORM in the form of pipe scale. For normal operations, Rocky Mountain Recycling does not possess a radioactive materials license.

"The Department responded to Rocky Mountain Recycling on December 29, 2011. Two fixed gauges were at that location, both TN Technologies model 5200 gauges with serial numbers B1130 and B1131. Both gauges contain Cs-137 (verified using an ldentiFinder). Gauge B1130 contains 20 mCi as of December, 1986 and gauge B1131 contains 20 mCi as of October, 1986. The gauges were being stored in a steel drum away from public access. A wipe test was taken in the field on the drum prior to opening and no contamination appeared to be present. Wipe tests were also taken on the shutters of both gauges and no contamination appeared to be present. Both gauges appeared to be in good shape, there was some rust and weathering on the outside of the source housing but otherwise the source housing and shielding appeared to be in working condition.

"The gauges were found without a lock to keep the shutter in the closed position. One gauge (B1131) was found with the shutter partially opened. Gauge B1130 could not have the shutter completely opened due to the steel mounting frame being bent. Both shutters could be manipulated by hand. Rocky Mountain Recycling provided padlocks to lock the shutter in the closed position for both gauges.

"Dose rate measurements were taken around the shielding of the gauges. On contact, both gauges measured approximately 2.5 mRem/hour. With the shutter open, the highest reading in the beam of gauge B1130 was approximately 60 mRem/hour on contact, 15-20 mRem/hour at approximately 1 foot, and 3-3.5 mRem/hour at approximately 1 meter. With the shutter open, the highest reading in the beam of gauge B1131 was approximately 70 mRem/hour on contact, 10 mRem/hour at approximately 1 foot, and 1.5 mRem/hour at approximately 1 meter.

"Around the drum the gauges were stored in, the highest reading on contact was 1.5 mRem/hour, the highest reading at one foot was 0.3 mRem/hour, and the highest reading at 1 meter was 0.08 mRem/hour."

AGREEMENT STATE REPORT - IODINE-125 BRACHYTHERAPY SEED MISSING FROM TRANSPORTATION PACKAGE

The following report was received by telephone from the State of Nevada.

A representative of the State of Nevada Radiation Control Program was notified by a call from Cardinal Health and Summerlin Hospital in Las Vegas NV concerning a missing I-125 brachytherapy seed. Summerlin Hospital on or about 12/21/11 transferred 33 Iodine-125 brachytherapy seeds to Cardinal Health for shipment back to Bard Brachytherapy in Illinois. The 33 Iodine-125 seed shipment was packaged and sent by Cardinal Health to Bard via commercial carrier on or about 12/21/11. Upon receipt of the seeds by Bard, the top of the shipping pig was discovered to not be completely sealed. Some of the seeds were outside the pig but within the shipping package. After all the seeds were inventoried, a total of 32 seeds were received by Bard. At this time, one of the seeds appears to be unaccounted for. The missing I-125 seed had an activity of 0.23 milliCuries at the time of shipment. The half-life of Iodine-125 is approximately 60 days.

Bard has surveyed the local carrier that transported the shipment to its facility. It has also surveyed the regional facility of the shipping carrier. Cardinal Health and Summerlin are still attempting to confirm the original inventory of seeds was 33.

The State of Nevada is continuing its investigation of the missing seed.


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.

UNAVAILABILITY OF TECHNICAL SUPPORT CENTER VENTILATION DUE TO SCHEDULED MAINTENANCE

"At 0400 EST on Tuesday, January 3, 2012, the Cook Nuclear Plant (CNP) Technical Support Center (TSC) air conditioning and charcoal filtration systems will be removed from service for scheduled maintenance.

"Under certain accident conditions the TSC may become unavailable due to the inability of the air conditioning and charcoal filtration systems to maintain a habitable atmosphere. Compensatory measures exist to relocate TSC personnel to the unaffected unit's control room if necessary.

"TSC ventilation system maintenance is scheduled to be completed by 1500 EST on Tuesday, January 3, 2012.

"The licensee has notified the NRC Resident Inspector."


* * * UPDATE FROM BEN HUFFMAN TO DONALD NORWOOD AT 1645 EST ON 1/3/12 * * *

"The TSC ventilation system maintenance was completed satisfactorily and the system was restored to service at 1644 EST on 1/3/12."

The licensee notified the NRC Resident Inspector. Notified R3DO (Valos).

PART 21 REPORT - DEFECTIVE 48 VOLT DC SAFETY RELATED POWER SUPPLIES

The following was received via fax:

"ATC Nuclear has identified a design defect associated with power supplies provided through ATC Nuclear, Schenectady, NY. The defect was identified during Failure Mode Analysis following return of one of the units from the customer. The 48 VDC Power Supplies, PIN DA265A1879P00/ST were provided as safety related components to Entergy's Pilgrim Station under Purchase Orders 10240621, 10282296 and 10308991. Entergy's Pilgrim Station is currently the only station in possession of these items. The failures are exhibited as a spurious overvoltage shutdown condition when power is applied or a spurious overvoltage shutdown condition if the overvoltage circuit becomes contaminated with particulate or other material. The design defect is related to the specific silicon control rectifier used in the over voltage protection circuit. An extent of condition review is ongoing to determine if other power supplies provided under these three purchase orders are affected. Currently none of the other power supplies provided have exhibited this condition.

"The affected serial numbers are: 90922-1, 90922-2, 90922-3, 91013-1, 91013-2, 91013-3 under purchase orders 10240621 and 10282296.

"The affected serial numbers are: 110512-1, 110512-2, 110512-3, 110512-4, 110512-5 under purchase orders 10308991.

"ATC does not have sufficient information to evaluate the safety significance of the defect because the quantities and locations of the power supplies currently in use is not known.

"Information Contact: Ray Chalifoux ATC Nuclear (865) 384-0124."
