No, the Sultanate of Oman does not possess any operational nuclear power plants, atomic energy reactors, or active nuclear fuel cycle facilities within its national borders. The country relies primarily on natural gas and oil-fired thermal plants for its domestic power and water desalination needs, alongside a growing portfolio of utility-scale solar energy investments. While government energy planners continuously review long-term technological roadmaps, no commercial nuclear reactors have been constructed or integrated into the Omani national electrical grid to date.
