With upcoming (continuum) surveys of high-resolution radio telescopes,detection rates of fast radio bursts (FRBs) might approach $10^5$ per sky perday by future extremely large observatories, such as the possible extension ofthe Square Kilometer Array (SKA) to a phase 2 array. Depending on the redshiftdistribution of FRBs and using the repeating FRB121102 as a model, we calculatea detection rate of multiply-imaged FRBs with their multiply-imaged hostscaused by the distribution of galaxy-cluster scale gravitational lenses of theorder of $10^{-4}$ per square degree per year for a minimum total flux of thehost of 10 $\mu$Jy at 1.4 GHz for SKA phase 2. Our comparison of estimateddetection rates for quasars, supernovae, gamma ray bursts, and FRBs shows thatmultiple images of FRBs could be more numerous than those of gamma ray burstsand supernovae and as numerous as multiple images of quasars. Time delaysbetween the multiple images of an FRB break degeneracies in model-based andmodel-independent lens reconstructions as other time-varying sources do, yetwithout a microlensing bias as FRBs are more point-like and have shorterduration times. We estimate the relative imprecision of FRB time-delaymeasurements to be $10^{-10}$ for time delays on the order of 100 days forgalaxy-cluster scale lenses, yielding more precise (local) lens properties thantime delays from the other time-varying sources. Using the lens modellingsoftware Grale, we show the increase in accuracy and precision of thereconstructed scaled surface mass density map of a simulated cluster-scale lenswhen adding time delays for one set of multiple images to the set ofobservational constraints.
