Security is not much of a concern. An attempt to seize the ship means you can failsafe the reactor and drop it to the bottom of the ocean. Pirates and lesser nation-states won't have the resources to recover it.

Then there would be a nuclear reactor sitting on the ocean floor for some unknown amount of time.

  But in the scheme of things, that’s fine. There are several nuclear subs and munitions at the bottom and there aren’t reports of terrible radiological effects.

    The lack of reports means very little.

      Nah, we all know that there are dozens of entities out there who would _love_ to publish the "Sunk US sub causing elevated radiation levels!" article. The incentive is high. So the absence of the report does mean something.

        ...and how are they going to collect evidence?

        Literally nobody cares.

Denial of service attacks on ocean shipping are a lot easier if every ship dumps the engine at the first sign of trouble.

  Unless you're actually boarded, why would you drop the reactor? The point is that a hypothetical commercial shipping reactor would have to be a self-contained, intrinsically safe design with no user-servicing - this is the sort of design pebble-bed reactors the general modular reactor concept points towards. The idea is that the reactor is mounted at the bottom of the hull, basically only provides electricity out as a "black box". It's not reachable by the crew from inside the ship, and gets a set of failsafe charges which cut it loose from the ship if it becomes unhappy about it's situation - i.e. if its GPS signal is cut for too long, if it strays from it's geofence boundary, or if someone tries to breach it's location in the ship. Even if you paid off the crew, they don't have control over the powerplant. Fairly obviously you wouldn't want to leave a reactor on the seafloor, but if it drops itself then like a blackbox it triggers a sonar beacon and whoever commissioned it (presumably a well-regulated US firm) would respond to collect it.

You've got to be kidding. Low paid commercial crews are subject to bribery, and often don't even keep a close watch for security threats. Plus no nation state will allow a nuclear powered merchant vessel into port if there's a risk of a damaged reactor getting dumped into their waters. It's just totally unrealistic, the kind of thing that only a programmer with zero time on the water would propose.
