So we’re not stuck with a 1 meter water jacket? How thick of a borated polyethylene jacket would be required to match the water’s shielding properties? I know this won’t scale down to a car, but this could open a lot of bus and truck applications if the bulk is ~25% to 50% of the current water jacket.
Trucks have more flexibility in weight distribution. But really high-energy-density batteries will probably be available long before special FoFus for vehicles! Consider how much in-place generation there is to handle, first.
