Does the plan rely on future drop-in modular reactors?

Is the battleship plan banking on future modular-reactor production that can supply drop-in units?

Not in the current proposal described here, although the reply leaves that possibility open over a longer period.

The reply does not treat a future drop-in modular-reactor supply chain as a present assumption of the battleship plan. It allows that the industrial picture could change over a longer period, without giving a timetable or identifying a selected modular design.
