POTENTIAL OVEREXPOSURE AS RECORDED IN PERSONAL DOSIMETER
This is a preliminary report of a potential reportable event under 10 CFR 20.2203(2)(i). Nuclear Technologist dosimeter readings values for the month of February 2003 were reported by the NVLAP-accredited dosimeter company at 7877 mrem DDE. The Hospital does not have any other technologists, physicists or physicians with dosimeter readings above ALARA-1 levels for the month of February 200. The Licensee reported that there has been no unusual sources or amounts of activity present within their facility which could explain only one individual receiving 100 times their "normal" range occupational exposure in a single month.
The Licensee is making preparations to conduct experiments in conjunction with the dosimeter company to duplicate the unusual exposure pattern and will complete and file a final report.

MANUAL REACTOR TRIP DUE TO LOSS OF CONDENSER VACUUM
"At 1603 EST, PSL [Plant Saint Lucie] Unit 2 was manually tripped due to increasing condenser backpressure (loss of vacuum). The manual trip is considered an RPS [Reactor Protection System] actuation. The plant was stabilized in Mode 3. Auxiliary Feedwater actuation occurred due to reduced steam generator level, as expected. The 2A and 2B AFW [Auxiliary Feedwater] pumps started and supplied feedwater to the 2A and 2B S/Gs [steam generators]. The 2C (steam driven AFW pump tripped. This was not expected. The 2C AFW pump has been reset for operation, but was not tested."
The reactor was shutdown with all control rods fully inserted, the unit is currently stable in mode 3 with the main feedwater pumps supplying cooling to the steam generators. With the exception of the 2C steam driven AFW pump, all other electrical power sources and decay heat removal systems functioned as required. This incident had no impact on Unit 1 which remains at full power.
The Licensee notified the NRC Resident Inspector.

MEDICAL EVENT INVOLVING ADMINISTRATION OF LESS THAN PRESCRIBED DOSE
A physician prescribed a dose for an outpatient therapy at 25 millicuries of Iodine 131. After completion of the treatment it was determined that the patient actually received an exposure of 18.1 or 27.6% less than the prescribed dose. The empty vials of Iodine 131 were re-assayed and 6.4 millicuries of Iodine 131 apparently remained adhered to the glass vial. The adherence of Iodine to the vial is being assessed by the Licensee and NRC Region 3. The patient was notified of this incident by the attending physician and the patient will return for administration of the remaining dose.
