AGREEMENT STATE REPORT - REPORT OF LEAKING SEALED SOURCE

The following information was received by e-mail:

"On Tuesday May 11, 2010, the licensee discovered during a routine leak test that a Ni-63 source in a Shimadzu GC-14A gas chromatograph was leaking, presenting 0.0142 microCi. The source was identified as an NRD model N-100, serial number 616355, with an original activity of 9.98 mCi on 3/23/03 and a current activity of 9.50 mCi.

"A second leak test confirmed that this was not a false positive. Surveys of the instrument and area presented no evidence that contamination had spread.

"The device containing the Ni-63 source was removed from service and taken to the licensee's radioactive waste storage facility."

AGREEMENT STATE REPORT - LOST TRITIUM EXIT SIGN

The following was received from the State of Oklahoma via e-mail:

"On May 14, 2010, Oklahoma Department of Environmental Quality (ODEQ) received telephone notification from American Airlines Maintenance and Engineering Center (AA) that they had lost one (1) tritium (H-3) radioluminescent exit sign containing a maximum total of 3.5 Ci of H-3. At this time, no further information is available; however, updates will be made to NMED as ODEQ receives updates from AA."

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

TECHNICAL SUPPORT CENTER NONFUNCTIONAL

"At 1530 on May 14th, 2010, Three Mile Islands Technical Support Center (TSC) ventilation, filtration and climate control system was identified as nonfunctional. Site emergency implementation procedures provide direction for performance of TSC functions in alternate locations. This failure affects the ability of the TSC ventilation to maintain adequate radiological habitability in the event of an emergency with an airborne radiological release. All other capabilities of the TSC are unaffected by this emergent condition. This condition is considered a major loss of emergency assessment capability and is reportable under 10CFR50.72(b)(3)(xiii)."

The NRC Resident Inspector has been notified.

* * * UPDATE FROM JEFF GOLDMAN TO JOE O'HARA AT 1934 ON 5/18/10 * * *

The TSC ventilation system has been repaired and is fully functional as of 1100 on May 15, 2010.

The NRC Resident Inspector has been notified.

Notified R1DO(Miller).
