Existing practice of nuclear desalination cogeneration incurs loss plant power generation because it competes for live steam with turbine. Such is completely avoided the design proposed in present study. The called GTHTR300 based on a high-temperature gas reactor rated at 600 MWt. Gas turbine used to replace as generator. converts about half reactor's thermal electricity while rejecting balance sensible waste heat be utilized multistage flash (MSF) seawater desalination. A new MSF process scheme and optimized efficiently match source. increments load recovery section number steps opposed keeping constant traditional process. As increases, more utilized, top brine temperature peak water production increased. Both tend increase yield. Operating similar stages, shown produce 45% than operating over same range. result, yields 56,000 m3/d generates 280 MWe efficiency without cogeneration. Copyright © 2012 John Wiley & Sons, Ltd.
