Nuclear energy generation in Texas
Texas may be known for its oil and wind, but nuclear quietly plays a critical role in the state’s energy mix. Two major nuclear facilities—South Texas Project (STP) in Matagorda County and Comanche Peak Nuclear Power Plant in Somervell County—provide over 4,000 megawatts of reliable, carbon-free electricity to the ERCOT grid.
The South Texas Project alone produces enough energy to power more than 2 million homes annually, with minimal emissions. Comanche Peak supports North and Central Texas with stable baseload generation, reducing pressure on fossil fuel plants during peak demand.
Beyond environmental benefits, Texas’s nuclear facilities provide thousands of high-paying jobs, stimulate local economies, and serve as anchors for energy resilience in a state frequently challenged by extreme weather and demand spikes.
Nuclear energy in medicine
Perhaps no sector has benefited more from nuclear technology than healthcare. Nuclear medicine uses radioactive isotopes to both diagnose and treat disease, offering powerful tools that traditional medicine cannot replicate.
Radiation therapy
Radiation therapy is one of the most effective cancer treatments available today. By directing high-energy radiation at tumors, oncologists can destroy malignant cells with precision while minimizing damage to surrounding healthy tissue. Techniques such as external beam radiation and brachytherapy have significantly improved survival rates for a range of cancers.
Diagnostic imaging
Advanced imaging technologies like PET (positron emission tomography) and SPECT (single-photon emission computed tomography) rely on radiotracers to provide detailed views of internal organs and tissues. These scans allow early detection of cardiovascular diseases, neurological conditions, and cancer—often before symptoms appear.
Medical sterilization
Gamma radiation is used to sterilize medical equipment, pharmaceuticals, and surgical supplies. Unlike traditional sterilization methods that rely on heat or chemicals, radiation sterilization is non-damaging and highly effective, ensuring product integrity and longer shelf life—critical for remote areas and emergency preparedness.
Industrial applications of nuclear energy
Nuclear technology enhances precision, safety, and performance across a wide range of industrial processes.
Industrial tracers
Radioisotopes serve as tracers in pipelines and manufacturing systems to monitor fluid dynamics, detect leaks, and optimize operations. This allows for predictive maintenance and improved safety in complex systems like refineries and chemical plants.
Inspection & instrumentation
Nuclear gauges and radiographic inspection tools are used to measure thickness, density, and composition in real time—vital in industries such as construction, automotive manufacturing, and aerospace. These non-destructive testing (NDT) methods ensure structural integrity without compromising the materials themselves.
Carbon dating
In geology and archaeology, radioactive isotopes such as carbon-14 are used to determine the age of artifacts and fossils. This scientific application of nuclear decay has helped researchers trace human history and environmental changes over millennia.
Nuclear-powered ships
Submarines, aircraft carriers, and icebreakers leverage nuclear propulsion systems for long-term, high-endurance operations. These vessels can operate for years without refueling, providing unmatched range and strategic mobility—especially important for defense, research, and Arctic operations.

This enables zero-carbon hydrogen fuel for fuel-cell electric vehicles (FCEVs), ammonia production, and industrial heating—creating synergy between nuclear power and future mobility solutions.
Food irradiation
Ionizing radiation is used to kill bacteria, parasites, and pests in food products, enhancing shelf life and reducing the need for chemical preservatives. Approved by the FDA and WHO, this method is increasingly used in the global food supply chain, particularly for spices, fruits, and meats.
Uses of nuclear energy in agriculture
Nuclear techniques contribute to sustainable farming practices, enhancing productivity while minimizing environmental impact.
Plant mutation breeding
Radiation is used to induce mutations in plants, accelerating natural selection to develop hardier, disease-resistant, or more nutritious crop varieties.
Fertilizer efficiency
Isotopic techniques track how nutrients move through soil and plants, allowing for optimization of fertilizer usage. This reduces waste and environmental runoff while improving yield.
Pest control
Sterile Insect Technique (SIT), which uses radiation to sterilize male insects, is an environmentally friendly pest control method. It helps combat pests like fruit flies and tsetse flies without the use of pesticides.
Material testing and process heat
Material testing
Radiographic testing with nuclear sources is a key quality assurance measure in industries like aerospace, automotive, and construction. It identifies defects and ensures compliance with safety standards.
