You still need a one meter thick blanket of lithium to capture the neutrons from the D-T reaction (and to generate more Tritium) so you are looking at modular 5

You still need a one meter thick blanket of lithium to capture the neutrons from the D-T reaction (and to generate more Tritium) so you are looking at modular 500MW reactors, although locating multiple reactors on the same site makes sense for fueling and maintenance purposes.
