TRISO-X Small Modular Reactor Siting Studies
Project Highlights
- Four SMRs to replace existing energy and steam assets nearing end of life.
- SMRs expected to reduce carbon emissions by approximately 440,000 metric tons annually.
- U.S. Department of Energy named Dow a subawardee under X-energy’s Advanced Reactor Demonstration Program.
Project Description
The Dow Seadrift project in Long Mott, Texas, is expected to provide the industrial manufacturing site with safe, reliable, zero-carbon-emissions for power and steam as existing energy and steam assets near the end of their lifespan. The project is expected to reduce the Seadrift Site’s emissions by approximately 440,000 metric tons of carbon dioxide equivalent annually.
Dow’s Seadrift Site covers 4,700 acres and manufactures more than four million pounds of materials a year for food packaging and preservation, footwear, wire and cable insulation, solar cell membranes, and packaging for medical and pharmaceutical products.
Project Scope
X-energy is developing the Xe-100 SMR with Sargent & Lundy providing site selection, environmental and licensing, including the required environmental report and safety analysis report to support the license application submitted to the U.S. Nuclear Regulatory Commission (NRC). The project team is also providing quality assurance and 3D plant model expertise.
Each unit of the “four pack” SMR is designed to produce approximately 80 megawatts of electric power. Sargent & Lundy has or is performing siting studies for four Xe-100 implementations, including at Washington Nuclear Project (WNP-1) and at the Dow Seadrift Operations in Texas.
For the Seadrift project, Sargent & Lundy is preparing the Environmental Report for the site as well as the preliminary safety analysis report as part of the Chapter 2 scope to support the submittal of the 10CFR Part 50 Construction Permit application to the NRC. Construction on the four-reactor project is expected to be completed in 2030.
