Abstract
Assuming an emissivity of 0.9, the total area required for SNPS radiators was calculated. An SNPS producing 13,000 MW of electrical power at an overall thermal efficiency of 56% would reject about 10,000 MW of heat. If the radiator has a length three times its width, then the width of the radiator base may be calculated as a function of radiator temperature. There are two such radiators used with the power plant. The base of a 750 K radiator for a 13,000 MWe SNPS would measure 200 meters, and its length would be 600 meters. At 1000 K, these dimensions are cut almost in half.
