A sensitivity study for the search for the charged lepton flavor violating process at the Super
-Charm Facility is performed with a fast simulation. With the expected performance of the current detector design and an integrated luminosity of
corresponding to one-year of data taking, the sensitivity on the branching fraction (BF) of
is estimated to be at the level of
. The sensitivity under different detector performances are also studied. With ideal performance, the BF could be probed to be
at 90% confidence level. The sensitivity is expected to scale with the square root of the luminosity, therefore with a total luminosity of
corresponding to ten-year of data taking, the sensitivity could reach
, which is about one order of magnitude improvement upon the current best upper limit.
