PERSON RECEIVED GREATER THAN 50 REM TO THE SKIN
THIS EVENT AS FAXED IN
NEN Life Sciences Product's called to report an event which resulted in one person receiving greater than 50 rem to the skin.
On December 4, 2000, at approximately 1530 hours, an NEN Life Sciences employee was transferring remotely 3.5 curies in 3 ml of Yttrium-90 in a vial from it's shielded dispensing container back to storage in a hot cell. During the transfer the cap fell off, allowing the vial to fall from the remote handling device and causing the material to be splashed onto the employee. The employee immediately contacted on site Radiation Safety Officer, who decontaminated the employee and had the employee shower.
Initial dose estimate for the highest effected area is 230 rads to the skin of the chin. A preliminary bioassay indicates an uptake of less than 1 microcurie; more bioassays will be taken.

BORON FOUND ON REACTOR HEAD THERMOCOUPLE NOZZLE.
On November 25, 2000, at approximately 1500 hours, during a routine visual inspection, engineering identified a small amount (about 1 cup) of boron accumulation at the interface between the outside of the reactor vessel head and an unused reactor head thermocouple nozzle. The source of the boron could not be concluded. Unit 1 has eight unused thermocouple nozzles that were used during original startup. Oconee Units 2 and 3 do not have these nozzles.
On December 4, 2000, at 2025 hours, a preliminary review of the eddy current test results from the subject unused thermocouple nozzle indicated that the source of the observed boron was most likely from a degraded pressure boundary associated with this thermocouple nozzle. In addition, a video inspection of the reactor head revealed trace amounts of boron around three (3) additional thermocouple nozzles and one (1) control rod drive nozzle. Leakage of this magnitude would not typically be detectable during operation.
A failure investigation team has been formed to evaluate this condition.
The NRC Resident Inspector was notified of this event by the licensee.

STOLEN ASSOCIATED SOILS ENGINEERING, INC, MOISTURE DENSITY GAUGE
The following text is a portion of a facsimile received from the State of California, Department of Health Services, Radiologic Health Branch:
"A CPN Moisture/Density gauge, model MC1 DR, S/N MD 01005909, was picked up from the office [in Long Beach, CA] on 12/03/00. It was locked down in the back of the truck of the gauge user [...]. The gauge was stolen between 2100 [PST] on 12/03/00 and 0530 [PST] on 12/04/00 from [the user's] trailer [park located in ...] Orange, CA [...]."
It was reported that the licensee notified the local Police Department and that the gauge contained an unknown quantity of americium-241/beryllium.
(Call the NRC operations officer for contact information.)
