Also a cable does not seem practical for communication. The ice may be more than a 100km thick. If the cable was only 1cm thick, which is quite thin for something in usch an extreme environment, you would already need 8m3 storage space, just for cable. That quickly becomes impractical.

Crake for communication a wire would bring problems as you say. What they could do, is drop radio beacons at certain distances along the way down which could then relay the signal back up the surface. Or maybe use really longwave radio signals which might be able to penetrate the ice, though could only carry very low bandwidth.

I also very much doubt a probe, even if it leaks, would damage the environment much, only very locally. Europa should have a vast ocean and Uranium doesn't dissolve that quickly. The oceans of Europa might contain some uranium already, just like Earth's ocean at 3 parts per billion (or 10^13 kg (2 × 10^13 lb) total). That's 10 with 13 zeroes.

And about contaminating another planet. You should know that the Jupiter system already has an extraordinarily intense radiation due to the strong magnetic field. Furthermore a reactor might help in heating and sterilizing the probe to remove any Earth life, which might be a far bigger threat to the alien life if it's there.
