I did of course skip over most of the other issues with a sinking ship, but the focus on the issues of having a polywell on a ship.

I would imagine there would be a "scram" system, so that on a ship in such a situation the engineer would hit a big red button and the magnets would be dumped into a resistor bank and the chamber flooded with air or perhaps an inert gas. With nothing of serious energy present after that, any radioisotopes would stay in the structure of the vacuum chamber, and not be any concern.

I don't know where the 0.2 % energy out as neutrons came from. My understanding is that it is more in the neighborhood of ~ 0.00001% or less (~ 1 part per ~ 40,000,000) Gamma radiation may be ~ 0.1 to 0.01%. [EDIT- referring to a P-B11 reactor]

The major concerns would be those related to the cooling fluid- possible steam , liquid nitrogen or helium. Failure of the superconductors might result in an explosion- similar to what happened to the LHC- destructive to the reactor- but little if any damage outside the engine room or vacuum vessel itself. The borane pressurized tanks might be toxic if ruptured, but the quantity should be tiny (~ 1 millionth of the equivalent diesel fuel quantity).

I suspect hot water/ steam concerns may be the major concern. There would be somewhere around 10-100 MW of waste/ process steam to deal with (or at least hot water).

In short, the concerns would probably be less than a conventionally fueled steam engine but more than a diesel or jet turbine power plant. Pollution concerns would be minimal, much less than concerns with thousands of tons of diesel fuel leaks in a conventional power plant.
Radiation concerns would be nearly nonexistent with a P-B11 reactor. With a D-D reactor, induced radiation would be mostly associated with solid structures, and would decay to small values within a few weeks, and almost completely decay within 100 years. Even with D-D Polywells the radiation concerns are very much less than with a fission reactor. There are no actinides decay chains that cause lingering heat problems or long term high level radiation concerns.

I like the p-B11 resonance peak at 50 KV acceleration. In2 years we'll know.

The development of atomic power, though it could confer unimaginable blessings on mankind, is something that is dreaded by the owners of coal mines and oil wells. (Hazlitt)
