A wide range of remote operations and examinations are performed in the facility's shielded cells and support areas and with facility equipment. Examinations, general-purpose experiment and materials handling, and service equipment can be changed remotely or supplemented in HFEF without major interruptions of operations. Certain facility components are outdated and need to be replaced or updated to support activities in HFEF. The following activities are included in the scope of this Environmental Checklist (EC): Visual Examination Machine--The motors and controls for the Visual Examination Machine (VEM) stage are obsolete.
