East Nusa Tenggara (NTT) is an area with many islands. low rainfall intensity makes NTT especially Sabu Raijua as one of the areas with minimal water, especially clean water. Likewise with electricity that has not been sufficient. High-Temperature Gas Reactor (HTGR) is a type of reactor that produces not only electricity but also could be used for cogeneration applications, such as desalination of seawater. In this research, calculation of reactor design performed by Standard Thermal Reactor Analysis Code (SRAC) code and using Japanese Evaluated Nuclear Data Library (JENDL) 4.0 as nuclear data library. Meanwhile, seawater desalination was analyzed using the Desalination Economic Evaluation Program (DEEP) code. The reactor was designed to produced 150 MWt power while seawater desalination used Multi-Effect Desalination (MED) method. As a result, this reactor design can meet electricity demand in the Sabu Raijua region. Also, seawater desalination yields 110000 cubic meters per day which are meet the needs of clean water.
