I assume you have to "slow down" ~107,000 kmph to fall into the sun, how much do you have to "speed up" to escape?

  ~11 km/s to escape the sun, ~30 km/s to fall into it. Escaping is easier.

    Just getting into the sun isnt enough. The sun's outer layers are not very dense. A blob of uranium might survive long enough to come out the other side, at least on the initial few orbits.

      I don't think we have to be very precise. It doesn't really matter if a blob of uranium orbits the sun for a few thousand years.

        In that case, why get it into the sun at all? Just put it into an orbit that doesn't intersect Earth.
