The proposed Long Mott Generating Station would be the first grid-scale advanced nuclear reactor deployed to serve an industrial site in North America.
Dow and X- energy, a developer of small modular nuclear reactors, introduced on May 18 the finishing of the U.S. Nuclear Regulatory Commission (NRC)’s environmental assessment for Dow’s proposed advanced nuclear project in Seadrift, Texas. The evaluation of no big effect moves ahead the construction allow application filed by Dow and X-energy.
The proposed Long Mott Generating Station is being evolved via Dow’s entirely owned subsidiary, Long Mott Energy, under the U.S. Department of Energy’s Advanced Reactor Demonstration Program. As per the declaration, the center would deliver both electricity and high-temperature industrial steam to Dow’s UCC Seadrift Operations, helping manufacturing of more than 4 billion pounds of materials per year. Once finish, the station is anticipated to be the primary grid-scale advanced nuclear reactor deployed to serve an industrial site in North America, stated Dow.
The NRC finished its environmental overview in under one year, as per the declaration. The evaluation analyzed ability effects to air quality, water resources and local species habitats. The companies stated that the overview advantages from X-energy’s pre-licensing work on its XE-100 small modular reactor design and a complete allow application.
“This is a major milestone for the Long Mott Energy venture, and we admire the acknowledge and efficient way wherein the NRC performed its evaluation,” Edward Stones, business vice president, Energy & Climate, Dow, stated in a declaration. “We are another step closer to expanding access to secure, clean, dependable, cost-competitive nuclear energy in the U.S.”
“There aren’t no shortcuts in nuclear safety. Every efficiency must be earned, and it starts with a complete, high-quality application and technology formed to be intrinsically safe,” added Dragan Popovic, chief global operating officer at X-energy.
X-energy’s XE-100 is an 80-megawatt high-temperature gas-cooled reactor that uses of helium as a coolant, which stays nonradioactive during operation. As per to the company, the layout’s minimal water necessities remove major aquatic ecosystem effects and decrease site disruption during construction.
In a separate announcement issued the same day, Dow released its Coolant Care Network, a service model designed to assist data center operators manage direct-to-chip liquid cooling systems using Dow’s heat shift fluids. As per the company, the network links data center operators with permitted service provider and qualified laboratories, with Dow presenting centralized data analysis, technical guidance and escalation support.
The release reportedly displays increasing demand for liquid cooling solutions as data centers expand to assist artificial intelligence and high-performance computing workloads.
The data center cooling market has attracted major attention from chemical manufacturers. As Chemical Processing reported in August 2025, the heat transfer fluid market is projected to attain $5.4 billion through 2029, with immersion cooling using a lot of the growth. Companies including Perstorp, Shell and Chemours have released new products and partnerships focusing on both single-phase and two-phase immersion cooling applications for high-density computing installations.
