AUTOMATIC SCRAM FOLLOWING MAIN TURBINE TRIP DURING SURVEILLANCE TESTING
"Unit 2 was operating at 80% Reactor Power, 937 Mwe. LOS-RP-M5, Turbine Control Valve Surveillance was in progress. An Automatic Main Turbine Trip and Reactor Scram occurred at 0618. Initial investigation indicates the cause of the Main Turbine Trip was High Vibration and Electro Hydraulic Controls (EHC) Master Turbine Trip.
"All systems operated as designed, there were no ECCS actuations. The lowest Reactor Water Level was minus 10 inches and recovered to the normal band. Reactor Pressure responded normally. No Safety Relief Valves Actuated. All Control Rods fully inserted.
"2A and 2C Circulating Water Pumps tripped during the Electrical Bus transfer following the Main Turbine Trip. This is suspected to be caused by electrical perturbation on the system but will be further investigated."
The licensee informed the NRC resident inspector.

TROXLER GAUGE STOLEN FROM COMPANY TRUCK AT RESIDENCE
Sometime between 0200-0930 hours on 5/27 a company truck was broken into removing a Troxler gauge and it's case. The gauge was properly stowed and it's case attached to the truck bed using a chain and lock. The truck was parked overnight at the residence of the employee at 402 Lochmoor Drive in Temperance, MI. The stolen Troxler is a model 3401B, S/N 13442, whose last measured activity on 4/30/01 was 5.6 mCi Cs-137 and 39 mCi Am-241/Be. The Monroe County Sheriffs Department in Temperance, MI and Ohio Department of Health were both notified. The licensee plans on issuing a press release.
****UPDATE ON 04/22/02 AT 1647 ET BY ALLEN TAKEN BY MACKINNON****
The above mentioned gauge was recovered this morning by the City of Bryan Local Emergency Management Agency. The gauge was found this morning in a ditch along side a highway still in its yellow case by some children. The source handle of the gauge was still locked and the only thing wrong was that the lock to the case had been broken off. The children that had found the gauge in its case called 911 and it was recovered by local law enforcement agency and given to the City of Bryan local Emergency Management Agency. The licensee was notified and picked up the gauge this morning. The gauge was leak tested and was found to be in perfect condition. R3DO (Jacobson) & NMSS EO (Wayne Hodges) notified.
