AGREEMENT STATE REPORT - SOURCE NOT ATTACHED TO SOURCE ROD
"On June 6, 2002 at 4:30 p.m. the Arkansas Department of Health was notified by Albemarle Corporation in Magnolia, Arkansas that a fixed density gauge source had been damaged. Albemarle has Arkansas Radioactive Material License ARK-717-BP-11-99. The device is a Ronan Engineering Company Model SA-15 containing two 5 millicuries sources of Cesium-137. The device was locked out on June 3, 2002. On June 6, 2002 while the source housing was being adjusted it was noted that the source rod was in a different configuration. Radiation surveys were performed and it appeared that one of the 5 millicuries sources was not attached to the source rod. The immediate area was secured and access has been restricted. Albemarle has contacted a consultant to assist in retrieval and packaging of the source for return to the manufacturer.
"The Department has sent two inspectors to the facility to investigate and assess the Incident on June 7, 2002. It appears that there may have been personnel radiation exposure due to this incident. This incident is under investigation."

GENERAL LICENSE CESIUM-137 SOURCE COULD NOT BE ACCOUNTED FOR
BJ Services, an oil field service company, determined that a general licensed source could not be located. The source, 250 mCi Cs-137 sealed in special form manufactured circa 1984, was installed in a Kay Ray Model 7063 instrument, S/N 28820, used for slurry density measurements. The last recorded location was Rock Springs, WY, on September 8, 1990 for a leak test. The instrument was then owned by Western Company which was acquired by BJ Services in 1995. BJ Services has discussed this incident with R4(Donovan) and will continue their investigation.

REACTOR TRIP CAUSED BY TURBINE TRIP
The reactor tripped due to a turbine trip due to a main generator trip caused by a high vibration on the main generator primary water pump shaft. All systems functioned properly. The plant is stable in Mode 3 with steam generator level being maintained with auxiliary feedwater (started automatically on low steam generator level) and excess heat being removed via the steam bypassed to the main condenser.
Primary water pump vibration trip is a 2 out of 2 channel coincidence. There was no indication of high vibration on the plant recorder. At the time of the trip, an investigation was ongoing on one of the channels that was in alarm. An investigation continues into the sensors and circuits associated with the high vibration trip. The plant will remain in Mode 3 until the problem is identified and corrected.
The licensee notified the NRC Resident Inspector.
