In-cell element laser profilometer at the hot fuel examination facility

A laser element profilometer has been installed in cell at the Hot Fuel Examination Facility/North (HFEF/N) at Argonne National Laboratory-Idaho. The profilometer can measure any diameter in the range from 2.5 to 25 mm (0.100 to 1.000 in.) with an accuracy of +-0.0025 mm (+- 0.0001 in.). The profilometer operates in conjunction with the HFEF/N element handling system and provides visual readout and digital and analog output of the diametral data.
