A helically coiled steam generator design has been found to provide many advantages when considering the requirements of a liquid-metal reactor (LMR) power plant. A few of these advantages are a smaller number of longer, larger-diameter, thicker-walled tubes; fewer tube-to-tubesheet welds; better accommodation of thermal expansion; compact heat transfer geometry; and the mitigation of departure from nucleate boiling (DNB) effects. Therefore, this type of steam generator was chosen as the reference design for the Advanced Liquid-Metal Reactor (ALMR) project. This design is a vertically oriented, helical coil, sodium-to-water counter-cross-flow shell and tube heat exchanger with water on the tube side. The SASSYS LMR accident analysis computer code has been improved over the last several years by the addition of a number of new component models, one of which is for the steam generator. In addition to this straight-tube model, a new model now treats helically coiled tubes in the steam generator. Both models are available to calculate once-through as well as recirculation-type designs.
