Dow's proposed advanced small modular reactor (SMR) project, developed by Long Mott Energy LLC, aims to provide clean and reliable power to Dow's Union Carbide Corporation Seadrift Operations site. This initiative, supported by the US Department of Energy's Advanced Reactor Demonstration Programme, seeks to replace aging energy assets with the Xe-100 advanced SMR, which boasts enhanced safety features and a strong safety profile demonstrated through extensive pre-application engagements with the Nuclear Regulatory Commission (NRC).

Once the construction permit is obtained, which may take up to 30 months, Dow plans to initiate construction, contingent on meeting financial targets. The Long Mott Generating Station is expected to be the first grid-scale advanced nuclear reactor serving an industrial site in North America, capable of producing significant baseload power and reducing emissions by approximately 440,000 tonnes of carbon dioxide equivalent annually. This project aligns with broader goals to expand nuclear energy capacity, as evidenced by Dow's recent commitment to tripling global nuclear capacity by 2050.
