3.1 Components
The SHLM MI4 source holder housing is a lead-filled, welded steel shell fitted with
an internal stainless steel cable assembly that functions as a carrier for source
capsules. The physical size determines the amount of lead each series model
contains for shielding. The dash numbers following the model number are
assigned to differentiate between the models with different amounts of shielding. A
“4” has the most shielding and a “1” has the least shielding. The source holder
design can use a point source in density and/or level measurement. The source
holder design can also use multiple point sources for level measurement.
The source carrier(s) is attached to a stainless steel cable and can have up to four
cables mounted in the cabinet to guide into the drywell. In all cases, the source
carrier(s) is inserted into the vessel well and returned to the source holder for
storage, where the sources can be locked in the OFF position.
