After almost 40 years and billions of dollars, the American nuclear industry's bid to revive itself is falling flat.

The effort represents both the last and only chance for the industry to follow through on oft-repeated calls for an American renaissance — and it exacerbates efforts to cut greenhouse gas emissions.
