THE US AIR FORCE REPORTED 18 LOST/STOLEN LENSATIC COMPASSES.
In March, 2000 the Air Force recalled all lensatic compasses NSN 6605-00-151-5337 and Barksdale AF Base, La. inadvertently sent 17 of these compasses to the Defense Reutilization Management Organization (DRMO) in Texarkanna,Tx. DRMO has no record of receiving these 17 compasses from Barksdale AFB. Since this time, Barksdale base supply had collected 3 more of these compasses and as of 6/3/00 one has been identified as being missing. Each of these 18 missing compasses contain 120 millicuries or less of tritium. Barksdale base supply is conducting an intense search for these compasses.

REACTOR SCRAM FROM 100% POWER DUE TO TURBINE TRIP.
During normal reactor operation at 100% power a turbine trip occurred causing a reactor SCRAM. A reactor recirc pump trip initiated and functioned normally. Four SRVs and both bypass valves opened to initially control reactor pressure. No. 1 bypass valve remained open for subsequent pressure control. The reactor vessel level transient (164 to 198 inches) resulted in a low level (170 inches) Group 2, 3, and 4 isolations.
Subsequent to the reactor SCRAM, a Reactor Feed Pump and HPCI turbine high level trip occurred (HPCI was not running at this time) at 211 inches. Operator took action to restore reactor vessel level and restart the 'B' reactor feed pump.
The exact cause of the turbine trip is unknown at this time. An intermittent 125 VDC Div 1 ground occurred following the SCRAM which is also under investigation.
A reactor recirc pump could not be restarted due to a high temperature difference and a normal cooldown was initiated to mitigate concerns of thermal stratification.
All rods fully inserted and the condenser is being used as the heat sink.
The NRC Resident Inspector was notified.
