MAIN STEAM LINE DRAIN CONTAINMENT ISOLATION VALVES MAY NOT ISOLATE
"Based on an engineering evaluation it appears that the inboard and outboard secondary containment isolation valves (total of 2 air operated valves) on the Main Steam Line drain system may not adequately close under all postulated conditions. This evaluation is based on 'worst case' assumptions for parameters such as air pressure to the valve actuator and maximum expected differential pressure across the valve. Both valves were declared inoperable and closed per the Tech Spec action statement at normal 100% power conditions."
The licensee will notify the NRC Resident Inspector.

AGREEMENT STATE REPORT OF STOLEN TROXLER GAUGE
A Troxler gauge was stolen from the back of a truck parked at the licensee's address sometime between 1700 EDT on 4/27/05 and 0800 EDT on 4/28/05. Bolt cutters were used to remove the Troxler which was locked. The State noted that the Troxler should not have been left in the truck overnight. The licensee will be contacting the Police.
The Troxler was a model 3440, Serial Number 15579, with an 8 millicurie Cs-137 and a 44 millicurie Am-241/Be source.
State Report number is 05-17
* * * UPDATE ON 12/16/2005 AT 10:30 FROM JEFFRIES TO ABRAMOVITZ * * *
The Troxler Moisture Density Gauge has been recovered. The thief was apprehended and as part of a plea agreement, on 12/14/2005, notified the Durham Public Defender of the location of the density gauge. The Troxler was found partially buried in the woods. It was not in its case but was protected from the elements by a vinyl container. The gauge was transported a few miles to the Troxler plant.
Notified the R1DO (Dimitridis), NMSS EO (Karas) and TAS (via E-mail).
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.

OFFSITE NOTIFICATION OF ONSITE FATALITY
"A vendor maintenance person died onsite from an apparent heart failure. The [death] did not appear to be directly job related. South Carolina OSHA will be notified. North Carolina, South Carolina, York County, Mecklenburg County, and Gaston County will be notified as a courtesy. The person was not contaminated and was transported offsite by ambulance."
The licensee has notified the NRC Resident Inspector.
