In the Picard era, Romulan warships are powered by captive singularities. What happens to them if the ship is destroyed?

Seriously, what happens?  Is there a sudden navigational hazard?  And what happens if the Romulan ship goes boom inside a solar system?

A natural quantum black hole is not stable due to Hawking radiation. The ones used in Romulan ships are artificially maintained, as soon as the mechanisms doing that are destroyed the black hole will evaporate (with an enormous release of energy in the process). It's not much different from a warp core breach on a Federation ship, though the explosion is much more consistent in its characteristics since an exploding Federation ship results in a turbulent mixture of matter and antimatter that has a more chaotic reaction curve.
