| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE REPORT - MISSING TRITIUM EXIT SIGN
The licensee notified the state of California that on 8/5/2011 they had discovered one of its tritium exit signs missing. The licensee is investigating. The sign contained approximately 20 curies of H-3.
* * * RETRACTION BY GENE FORRER TO VINCE KLCO ON 10/25/11 AT 1801 EDT * * *
Following a licensee review of inventory, the missing tritium exit sign was discovered. Therefore, the event is being retracted.
Notified the R4DO (Haire), FSME EO(Chang), ILTAB via email and Mexico via fax.
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 |

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text LOSS OF CONTROL OF AN I-125 BRACHYTHERAPY SEED
On October 10, 2011, North Carolina Radiation Protection (NCRP) received a call from the Radiation Safety Officer (RSO) at Marion L. Shepard Cancer Center in Washington, NC, informing them that on September 26, 2011, while working with I-125 brachytherapy seeds for calibration, they had discovered the loss of one of the seeds. The lost seed was a 0.346 mCi brachytherapy seed that had been received on September 23, 2011. According to the RSO, they had made every effort to locate the seed but could not find it. At that time, it was believed that the seed must have gone behind an un-movable counter in the hot lab at the hospital nuclear medicine department. The well counter they use is kept at the cancer center and taken to the hospital's nuclear medicine department when needed to assay the seeds.
According to North Carolina section .1645 of the rules, this amount did not require immediate phone notification but does require notification within 30 days by phone and a written report within 30 days of the phone notification.
On October 19, 2011, NCRP received a call from the State of Wisconsin to notify them that a licensee at the University of Wisconsin had received a well counter from NC that contained a brachytherapy seed.
It has not been the policy of the Cancer Center licensee to survey a well counter prior to shipment, since it should not contain any radioactive material, but in the future, well counters will be surveyed. The well counter belonging to the licensee was sent to Wisconsin for calibration and will be shipped back to the Marion L Shepard Cancer Center.
No personnel exposures occurred during this event.

| Event Text AGREEMENT STATE REPORT - MOISTURE DENSITY GAUGE STRUCK BY VEHICLE AT CONSTRUCTION SITE
The following was received from the state via fax:
"The on-duty State Response Coordinator (SRC) for the Wisconsin Department of Health Services (DHS) received a phone call at approximately 3:30 am that a moisture density gauge had been struck by a motor vehicle. The incident occurred at a road construction site near 1221 Northport Drive, Madison, WI. The gauge was in use with the operator in contact with it, when a car veered out of traffic into the construction lane. The operator was forced to jump out of the path of the vehicle, leaving the gauge. The vehicle struck the gauge, shattering the housing. The source rod with the Cesium-137 source detached from the housing. The Americium/Beryllium source remained within the housing. The SRC and licensee's RSO responded to the scene to supervise source recovery.
"The Cesium source was leak tested in-situ and determined to be intact. Surveys were performed in the affected area, with no contamination detected. A portion of the housing designed to hold the retracted Cesium source rod was found partially intact. The Cesium source was placed within the cavity and securely taped. The housing assembly was placed in the transport container for transport back to a licensed service provider for assistance with disposal.
"The driver who struck the gauge has yet to be located by the police. The licensee will be submitting a 30 day written report concerning this event."

"At 1534 on 10/25/11 Site Engineering and Licensing reported the following to the Operations Department:
"The following deficiency was identified during reviews for NFPA 805 Transition: Cable 1B11 (#12 awg - Fire Area Route 16, 17) from the shunt in the 250 VDC Battery Board 1 (0-BDDD-280-0001) compartment #1, to the control room ammeter 1-EI-57-38 mounted on Control Room Panel 1-9-8, is not fused or otherwise protected against an electrical fault. The 250 VDC Battery 1 is an un-grounded DC system. However, in a scenario where the 250 VDC Battery Board system negative becomes grounded at the same time the ammeter cable 1B11 has a fault to ground, the cable may not be protected and the cable could auto-ignite anywhere along the cables length from the ground fault location back to the battery source. For example, in a Fire Area 16 (Control Bay) scenario, these ground faults could result in a fire being spread from Fire Area 16 to Fire Area 17 (Battery Board 1). Fuses should be added to protect these cable conductors.
"A similar condition exists for the remote ammeters on Unit Battery Board 2 (Cable 2B11 - Fire Area Route 16, 18), Unit Battery Board 3 (Cable 3B11 - Fire Area Route 16, 19), Unit Battery Board 4 (Cable 2B4018 - Fire Area Route 16, 26), Unit Battery Board 5 (Cable 1B383 - Fire Area Route 16, 26), and Unit Battery Board 6 (Cable 3B336 - Fire Area Route 16, 26).
"This condition is reportable as an 8 hour notification to the NRC IAW 10CFR 50.72(b)(3)(ii)(B), 'Any event or condition that results in the nuclear power plant being in an unanalyzed condition that significantly degrades plant safety.'
"This is also reportable as 60 day written report IAW 10CFR 50.73(a)(2)(ii)(B).
"Fire watch compensatory measures are in place for the Fire Areas of concern. Ref. FPIP#09-1920
"The NRC resident has been notified of this event.
"This event was entered into the licensee's Corrective Action Program as PER# 452185." | |
