"This report documents a condition in which WBN [Watts Bar Nuclear] Unit 1 met the criteria to declare a NOUE [Notification of Unusual Event] based on RCS [Reactor Coolant System] unidentified leakage. Prior to declaration, the event was terminated thus no declaration was made. This event is reportable within one hour as an acceptable alternative to reporting in accordance with 10CFR50.72(a)(1)(i) - declaration of any of the emergency classes specified in the licensees approved emergency plan.
"During tagout installation in support of planned maintenance on the cation bed flush valve (1-FLV-62-921) in the CVCS/Letdown system, isolation boundary valve leakage of approximately 80 gpm was present for approximately three minutes. The leakage was terminated by reclosing opened vent (1-VTV-62-917) and drain valves (1-DRV-62-920). Cation Bed Inlet (l-ISV-62-915) and Outlet (1-ISV-62-916) and all other boundary valve isolations were verified to be in the correct, closed position per the tagout instructions. This RCS leakage was directed to the Tritiated Drain Collector Tank, thus all leakage was contained within plant systems and no radiological releases resulted. A work order will be initiated to troubleshoot and repair the faulty isolation valve.
"This amount of leakage is in excess of the amount specified in WBN Emergency Plans for declaration of an NOUE based on >10 gpm unidentified leakage per EAL 2.5. Prior to declaration, the event was terminated, thus no declaration was made."
The State of Tennessee and the NRC Resident Inspector has been notified.
* * * RETRACTION ON 9/15/2009 AT 1113 FROM WES DANIEL TO MARK ABRAMOVITZ * * *
"Event Notice 45331 reported a condition in which WBN Unit 1 conservatively determined it met the criteria to declare a NOUE based on RCS unidentified leakage. Prior to declaration, the event was terminated thus no declaration was made.
"Based upon further review and discussion with others in the industry, the NOUE criterion cited, EAL 2.5, applies to specific sources of excessive RCS leakage. The source of the leakage discussed in the event has been confirmed as CVCS leakage, not RCS leakage. An action to clarify the basis and scope of this EAL is being pursued within TVA's Corrective Action Program. Therefore, Event Notice 45331 is being retracted.
"The NRC resident has been notified."

| Event Text AGREEMENT STATE REPORT - CONTAMINATED PHARMACY SHIPMENT PACKAGE
'[A] contaminated package [was] received at Mission Hospital from Cardinal Health - Asheville. The RSO [Radiation Safety Officer] of Mission Hospital received a shipment of Tc-99 unit doses from Cardinal Health pharmacy. The exterior of the box was contaminated to [approximately] 180,000 dpm/100 [square centimeters].
"Upon determination of the contamination, Mission Hospital contacted Cardinal Health pharmacy and they came and picked up the box.
"Mission Hospital did not open the box.
"After the box was picked up, a small spot of contamination was found on the absorbent paper that the box had been placed on. Mission Hospital removed the paper, which removed the contamination, and placed it as waste into their decay-in-storage area. This level exceeds the reportability limit of 22,000 dpm/100 [square centimeters] of 15A NCAC [North Carolina Administrative Code] 11.1627; which references 10 CFR 71.87; which references 49 CFR 173.443.
"15A NCAC 11.1627(d) requires an immediate notification to the [North Carolina Radiation Protection Section] Agency."

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE REPORT - LOST TRITIUM EXIT SIGNS
On 9/11/09 at 1246, the State of California was notified by Boeing that 15 tritium exit signs could not be accounted for in their Long Beach, CA location. The signs were manufactured by Safety Light Corporation and the serial numbers are as follows: 387873, 387874, 387875, 392809, 392810, 392811, 392812, 392813, 392814, 392815, 392816, 392817, 392818, 392819, 392820. The original activity of these signs is typically 11.5 Curies each.
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.
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 | |
