Thanks. That helps with my original question - how portable will this be? If it just needs a very small nuclear reactor with a tiny amount of fuel, then they should be able to have a power source "that generates 25 megawatts" and can "fire 10 times a minute through a barrel capable of lasting 1,000 rounds" on a ship. But what about a truck? Having a weapon with a 125 mile range isn't necessarily all that great if it is too big and heavy to get within 125 miles of most of the things you want to shoot at.
