STRONTIUM-90 PRESSURE INDICATORS MISSING DURING AN ANNUAL INVENTORY
"While conducting the Annual Radioactive Inventory [of pressure indicators], a discrepancy was noted in the on-hand balance of the subject NIIN (National Item Identification Number). The current electronic inventory balance was 138 ea, but a physical check of the location could only locate 136 for a shortage of 2 ea. An initial search of the Radioactive Materiel Storage Area did not locate the item. The Service Provider and Continuing Government Activity personnel will begin a review of all transaction since the last reconciled inventory in an attempt to identify potential transaction errors.
"The pressure indicator in its shipping container is authorized to ship as an expected package with an external dose rate of less than 0.5 mrem /hr on contact."
The pressure indicators contained 500 microcuries of Sr-90.
* * * RETRACTION FROM D. COLLINS TO E. SIMPSON ON 11/02/09 AT 1336 EST * * *
The inventory items that were previously thought to be lost or stolen were subsequently located during a more comprehensive search of the warehouse.
"A number of potential process weaknesses lead to the initial report of the inventory discrepancy. While available, handheld Radiofrequency transmitters were not used for all transactions, causing delay in inventory balance updates (issues and re-warehousing not immediately accounted for), [and] similar packaging were found to contain either one or two items per packaging.
"DDC Inventory Control [licensee] canceled the current electronic inventory, processed all open transactions and ran an updated inventory. Physical inventory and verification of serial numbers accounted for all sources identified in electronic inventory system.
"Hand-held Radiofrequency devices will be used in the future for all inventory transactions to alleviate delay in transaction processing. Also, items were repackaged to ensure that only one device was in each package."
Notified R1DO (Barkley), R4DO (Hay), FSME EO (White) and Mexico via fax.
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. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf
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 is it being categorized as a less than Category 3 source

MANUAL REACTOR SCRAM DUE TO REACTOR RECIRCULATION PUMP TRIP
"On October 16, 2009 at 0048 a manual reactor scram was inserted at the Perry Nuclear Plant.
"The plant was conducting a planned shutdown due to the Division 2 Emergency Service Water inoperability. While shifting reactor recirculation pumps to slow speed the 'A' pump failed to transfer and tripped off. Following stabilization from this event a manual reactor scram was inserted from approximately 30% power. This was different from the initial planned shutdown sequence.
"Following the scram all systems operated as expected. The plant is stable in Mode 3. The plant will transition to Mode 4 in accordance with Technical Specification 3.7.1 (Emergency Service Water Inoperability) required actions."
All control rods fully inserted and the plant electrical power is in a normal line-up.
The licensee notified the NRC Resident Inspector.
