Why pick 200MW as the standard power station size for your study. New Nuclear/Coal/Oil Builds will usually be in the order of 1GW to 2GW per plant and often 2 such plants on the same site. It does not seem to make economic sense to build smaller units.

The reference I found for nuclear costs was $/kWh, without variation for size of plant. Thus, it didn't seem relevant to consider a larger plant. Do you have another references that indicates how larger installations affect construction cost?

*Nuclear*
Calculation:
  $1500/kw * 200,000kw = $300,000,000
Nuclear overnight construction costs ranged from US$ 1000/kW in
Czech Republic to $2500/kW in Japan, and averaged $1500/kW. Coal
plants were costed at $1000-1500/kW, gas plants $500-1000/kW and
wind capacity $1000-1500/kW.
