Contrasted to the prior art, the present invention presents a path for the cycle steam having the fewest possible changes in direction to minimize parasite pressure losses. This invention accommodates proportioning the flow areas of the moisture separator—reheater(s) assembly to optimize performance of extracting the maximum energy from the cycle steam and in view of the economics of first cost and operating cost. The reheater tubes are straight, not U-tubed, and sloped towards the reheat steam condensate discharge. It utilizes an internal baffle in the reheating steam manifold, features which would mitigate tube binding, steam distribution to the tube bundles, flow oscillations, etc. which are expensive and difficult to alleviate.
