  Tokamak power plants are studied with advanced and conservative design philosophies to identify the impacts on the resulting designs and to provide guidance to critical research needs. Incorporating updated physics understanding and using more sophisticated engineering and physics analysis, the tokamak configurations have developed a more credible basis compared with older studies. The advanced configuration assumes a self-cooled lead lithium blanket concept with SiC composite structural material with 00% thermal conversion efficiency. This plasma has a major radius of 0.00 m, a toroidal field of 0.0 T, a q₉₅ of 0.0, aᵦtotal
