| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text 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 |

| Event Text AGREEMENT STATE - MOISTURE DENSITY GAUGE DAMAGED AT CONSTRUCTION SITE
The following was received from the state via fax:
"The SC [South Carolina] Department of Health and Environmental Control (SCDHEC) was notified Tuesday, October 27, 2009 at 2:10 p.m. that a Humboldt Model 5001 portable moisture density gauge had been damaged on a job site in North Charleston, SC. The gauge contained 11 milliCurie maximum of Cesium 137 and 44 milliCuries maximum of Americium 241/Be. [The] F&ME employee notified the department (SCDHEC) that a gauge technician had been in the process of performing a standardization test with the gauge when it was hit by a motor grader. [The company representative] was present at the job site when the event occurred. [The company representative] informed SCDHEC that the area had been secured with both the gauge and motor grader within the perimeter. [The company representative] was advised to maintain surveillance of the gauge until SCDHEC personnel could respond.
"Once on site, SCDHEC personnel determined there was no release of radioactive material and that the Cesium 137 source was still in the locked position. The gauge was placed in its storage container and secured. The licensee informed SCDHEC that he would transport the damaged gauge back to the home office in Columbia, SC that same evening and secure it until the manufacturer could be contacted on Wednesday, October 28, 2009. The licensee would then follow the manufacturer's instructions for the disposition of the device. As more information is available, this notice will be updated. The licensee was advised that a written report detailing this event must be submitted to the department (SCDHEC) within 30 days. The event is open and pending further investigation by the licensee and the department (SCDHEC). Updates will be made through the NMED (Nuclear Materials Event Database) system." |

"On 11/2/09 at 0712 shutdown cooling (SDC) was lost on Dresden Unit 2 when a recirculation loop temperature element (2-0260-13B) failed upscale. Unit 2 was in the process of initial cooldown for entry into a refueling outage. Recirculation loop temperature was approximately 224 degrees F based on alternate indications. The circuitry was jumpered out and SDC was restarted at 0748. The Recirculation loop temperature was at 260 degrees F upon restart. At 0835, the reactor entered Mode 4 (i.e., Recirculation loop temperature less than or equal to 212 degrees F and Mode Switch in Shutdown). This event is reportable under 10CFR 50.72(b)(3)(v)(B). This event is being reported based on lessons learned from industry experience and is undergoing further review.
"The licensee notified NRC Resident Inspector." |

"At 2242 on November 2, 2009 Indian Point Unit 2 reactor tripped from 100% due to a turbine trip. The turbine tripped due to a generator lockout relay actuation. The investigation into the relay actuation is ongoing. All systems responded as expected. Auxiliary feed water is providing steam generator feed and levels are being maintained. No steam safeties opened and no coolant system relief or safety valves actuated. The reactor plant is in mode 3 and stable. Unit 3 was unaffected and remains at 100%."
The trip was characterized as uncomplicated. All rods fully inserted and stabilized at the normal mode 3 no-load Tave and pressure. The shutdown electrical lineup is normal and the unit was not in any significant LCOs at the time of the trip. The licensee stated that they were not performing any maintenance or surveillances at the time of the trip. Initial investigation has not revealed any obvious generator electrical system issues but a detailed investigation is ongoing.
The licensee has notified State and local authorities and the NRC Resident Inspector. | |
