The conceptual design of a fog-cooled light watermoderated reactor using quality at inlet was re-evaluated with particular emphasis on the influence of coolant density changes on reactivity at startup and shutdown. Although this design calls for steam recirculation equipment, it offers cost advantages over dual cycle boiling water reactors, such as Dresden and SENN by virtue of a lower steam void coefficient, which permits the use of a single direct cycle. When compared to more advanced boiling waters using a single direct cycle, the fog- cooled plant using quality inlet is not expected to be competitive. An alternate design, using saturated or slightly subcooled water at core inlet and mass velocities sufficiently high to yield fog flow conditions over a large portion of the coolant channels, promises to result in cost savings over single direct-cycle boiling water reactors of 0.15--0.30 mills/ kwh. These savings are the result of improved voiding characteristics, permitting higher exit qualities and reduced water recirculation rates. (auth)
