[en] Developments in investigations of dual purpose nuclear power plant features for Egypt were conducted with the aim of assessing the potentialities of such a plant and its suitability to the Egyptian conditions. High points of the results showed the capital cost to be 500 to 600 PoundKwe, the fuel cost to be 2 to 4 mills/Kwh, and the total generating cost to be 12 to 15 mills/Kwh. Steam temperature to desalination was 140 C. The optimum Mwe to Mgd ratio was close to 2.0. Energy cost was 63 C/Mbtu. Desalination plant initial cost was 1000 Pound/K ga, output ratio 13.1, load factor 85% leading to water cost of 90 c/K gal. Preliminary features for a 400 Mwe-250MGD-PWR plant with MSF-LT evaporator coupled were outlined. (author)
