Superheating steam in the boiling water reactor is desirable because it avoids excessive wetness and improves ating can be incorprated in nuclear plants either by the addition of a separate oil-fired superheater or by nuclear methods. Evaluation studies indicats that the cost of power from a large nuclear plant using internal nuclear superheat will be less than the equivalent saturated steam plant. The Pathfinder, or Controlled Recirculation Boiling Reactor, is an experimental unit on a commercial scale. With a net output of 62 Mw, it is the largest nuclear-superheat unit of the BWR type under construction. Forced recirculation of the coolant enables accurate control by coolant volume variation and increases the general efficiency of the plant. Core design is complex and consists, in effect, of two concentrically located separate cores. Diagrams of the reactor vessel, core, and plant are included. Based on Pathfinder design data, a target plant with an output of 330 Mw was designed. A simp1ified flow diagram for this project, with nuclear superheater and reheater, is included. (M.C.G.)
