We present a feasibility study for passive sounding of Uranian icy moonsusing Uranian Kilometric Radio (UKR) emissions in the 100 - 900 kHz band. Weprovide a summary description of the observation geometry, the UKRcharacteristics, and estimate the sensitivity for an instrument analogous tothe Cassini Radio Plasma Wave Science (RPWS) but with a modified receiverdigitizer and signal processing chain. We show that the concept has thepotential to directly and unambiguously detect cold oceans within Uraniansatellites and provide strong constraints on the interior structure in thepresence of warm or no oceans. As part of a geophysical payload, the conceptcould therefore have a key role in the detection of oceans within the Uraniansatellites. The main limitation of the concept is coherence losses attributedto the extended source size of the UKR and dependence on the illuminationgeometry. These factors represent constraints on the tour design of a futureUranus mission in terms of flyby altitudes and encounter timing.
