INVALID EMERGENCY DIESEL GENERATOR ACTUATION DURING TESTING
"This is a verbal report in accordance with 10 CFR 50.73(a) (2)(iv)(A). It is not considered a Licensee Event Report. This event occurred with Unit 3 at 94 percent power while performing scheduled testing of the common accident signal logic. On March 6, 2002, at 2103 hours, an invalid signal caused the automatic actuation of the 3B Emergency Diesel Generator (EDG). The EDG functioned successfully, it was not required to tie to its respective 4kV shutdown board by design because the board was energized. The Reactor Protection System did not actuate. No other systems listed in 10CFR 50.73(a)(2)(iv)(B) were affected."
The licensee stated that the inadvertent actuation resulted from an insulator finger dislodging from an electrical contact during surveillance testing.
The licensee will notify the NRC Resident.

EXTREMITY OVEREXPOSURE
"[An individual] was observed by inspector Randy Erickson, Health Physicist with Region IV, dispensing radiopharmaceuticals that have caused an extremity exposure in excess of the limits allowed in 10 CFR 20.1201(a)(2)(ii).
"[The individual's] left hand index fingertip exposure is estimated at 700 R/yr. The assumptions for the dose estimate is based on the following calculation with the left hand index finger supporting a vial containing 100 mCi of Tc-99m so it does not fall out of its lead shielding. Page 94 of the article 'Fingertip and Whole Body Exposure to Nuclear Medicine Personnel' references fingertip exposure of 56 R/year based on 100 mCi vial of Tc-99m, 1000 draws/year at 6 seconds per draw. This scenario nearly matches the procedure followed by [the individual].
"40 draws/day x 6 seconds/draw x 6 days/week x 50 weeks/year = 20 hours/year
"Based on the article, 1.6 hrs/year exposure to the finger = 56 R. Therefore, 56 R/1.6 hrs x 20 hrs = 700 R.
"An NRC form 5 has been completed for [the individual] for calendar year 2001. His total effective dose equivalent and total organ dose equivalent, maximum organ does not exceed the limits in 10 CFR 20.1201(a)(1) and (2)(i)."
