Nuclear technology leverages the energy stored within atomic nuclei to meet humanity’s major challenges. While most often associated with carbon-free electricity generation, nuclear energy also offers other useful applications which directly benefit society.
Nuclear reactors are designed to produce uranium and plutonium for nuclear weapon production and civilian electricity generation, testing materials for safety testing or creating medical isotopes, among other uses.
1. Power
Atomic facilities comprise approximately two deciles of the universal electrical yield, constituting it one of the peak wellsprings of carbon-impoverished vigor succeeding hydroelectric influence. Moreover, they furnish ample thermic energy exploited by manufactories for vitreous creation, concrete fabrication and metal refining courses as well as the refining courses themselves. What’s more, nuclear expertise is being enforced to decarbonize other divisions that primarily bank on fossil combustibles like conveyance (aerial, nautical, terrestrial).
Nuclear energy may be well known for providing low carbon electricity, yet many may underestimate its wider benefits in areas such as health, science, research, industry, water management, and the environment. Nuclear technologies like radioisotopes, reactor process heat and non-stationary power reactors play a pivotal role in providing services such as food and water security as well as public safety measures such as medical care or transportation systems – these aspects often go unsaid when people become unaware.
Nuclear power stations use uranium as fuel to generate energy by splitting nuclei of atoms apart, creating enormous quantities of steam which drives turbines and generators to generate electricity. Any remaining atoms can be recycled for future fuel production while any waste materials are carefully contained within large, refrigerated containers – this way there are no greenhouse gas emissions produced from nuclear energy as well as fluctuation of oil or gas prices that might otherwise have an effect.
Nuclear energy’s primary benefit lies in its ability to generate large amounts of energy with relatively limited fuel consumption, making it cost-effective for countries with limited resources and reliable, cost-effective sources of power. Nuclear technology also plays a crucial role in global defense applications from submarines to aircraft carriers.
Nuclear industry jobs span the globe and typically feature multiple nuclear power plants at most sites; each plant produces enough electricity for approximately 200,000 homes and typically takes between 40-60 years to reach full capacity, though regular safety inspections must take place in order to ensure safe operations.
Nuclear energy may present some risks, but nuclear energy remains an efficient and renewable form of energy that can help combat climate change by decreasing carbon emissions and producing less air pollution than coal or natural gas sources.
2. Agriculture
Nuclear technology plays an essential role in agriculture and food production – not only by producing electricity but also through plant mutation breeding with radiation; creating resilient crops more resistant to disease and insects without resorting to harmful pesticides, helping alleviate food shortages and poverty globally.
Nuclear technology can also help extend food products’ shelf lives and make them safer, by subjecting them to ionizing radiation which kills bacteria that spoilage their contents, making it unsafe for consumption. Irradiation is used by over half of restaurants and supermarkets worldwide – particularly those seeking to export produce; its application in raw meat exporting countries makes irradiation an indispensable solution; Cobalt-60 produced for food irradiation can only be produced at Canadian CANDU reactors.
Nuclear technology’s other uses in agriculture include using radiation to detect soil deficiencies, test quality fertilizers and enable scientists to better understand how plants take in nutrients from the ground. Such studies enable farmers to improve farming techniques such as knowing exactly how much fertilizer their crop needs or which brand of fertilizers would work best; additionally, understanding how plants utilize and absorb nutrients allows scientists to better predict climate change.
Radioisotopes and radiation play an essential part in medical diagnostics and therapy; one third of diagnoses and one fifth of therapeutic applications utilize nuclear medicine in developed nations. Studies of radioisotopes can also shed light on our environment and planet history – relative abundances of naturally-occurring radioisotopes can give geologists, archaeologists, hydrologists etc. an invaluable source of data for analysis.
As global population levels continue to expand, it becomes ever more critical that all available technologies and agricultural processes be utilized effectively. Over 800 million people in Africa and other developing nations suffer chronically undernutrition; IAEA works hard to supply nuclear technology to these areas so they may provide their citizens with adequate sustenance.
3. Medical
Nuclear power plants produce most of the world’s low-carbon electricity supply. But their fission can also provide many other applications: medical diagnostic procedures and drug production; food sterilization; transport infrastructure development; water resources protection and environmental preservation are just a few more benefits that emanate from fission atoms.
Most people are familiar with the use of radiation and radioisotopes in medicine for diagnostic and therapy purposes, especially identification (identification) and treatment (therapy). Each year in developed nations one out of every 50 people undergo some form of diagnostic nuclear medicine procedure and production of diagnostic imaging radionuclides continues to increase rapidly.
Nuclear techniques play a pivotal role in fighting infectious and hereditary diseases. They can detect diseases as they move among species – for instance avian flu in Asia and Ebola in Africa – as well as aid diagnosis of human illnesses using tools like polymerase chain reaction that can detect cystic fibrosis, sickle cell anemia and various forms of cancer.
Hospitals rely on gamma radiation sterilization technology to disinfect medical products and equipment more quickly and affordably than heat sterilization methods, making this approach both more cost-effective and efficient than heat sterilization processes. This technology disinfects disposable syringes as well as gloves, stethoscopes and other forms of medical gear – like disposable syringes – which make hospital life simpler for their staff and patients.
Gamma radiation sterilization of food products is another highly-effective means of disinfecting raw foods, killing off harmful pathogens that threaten consumers’ health and protecting against any associated diseases. As the only practical method available to quickly sterilize both fresh and frozen food without significantly altering taste or nutritional value.
Radiation offers many useful applications; one such application involves creating hydrogen gas from water by using ionizing particles to produce it and convert it to fuel cells without emitting carbon-producing fossil fuel emissions. Hydrogen generated through clean renewable sources provides energy sources capable of powering cars, buses, boats and aircraft alike.
Radioisotopes have proven useful across a range of fields, from geology and archaeology to climate science. Their abundance in nature provides invaluable clues as to the source, movement and history of materials studied by geologists, anthropologists, hydrologists and archaeologists alike.
4. Space Exploration
Space exploration missions to Jupiter, Saturn, Pluto and beyond would be impossible or severely limited without nuclear technology; solar panels cannot generate enough energy at these distances and chemical rocket fuel is too heavy to transport across space. Cassini, Voyager, Spirit and Opportunity Mars rovers used a Radioisotope Thermal Generator (RTG), which uses heat from plutonium-238’s natural radioactive decay to generate electricity – creating hundreds of watts for decades of travel through space travel – to power their missions
Radioisotopes employ similar technology for medical imaging and sterilization purposes. Physicians utilize gamma radiation to visualize inside human bodies, using it to target cancerous cells while leaving healthy ones intact; hospitals use radiation sterilization techniques on items like syringes, surgical gloves and medical instruments – an increasingly important feature.
Nuclear technology has long been utilized for spaceflight. Nuclear propulsion provides initial rocket launches with propulsion; more recently it provides electricity to unmanned spacecraft and rovers; improves performance for space shuttles as well as successor vehicles such as Space Launch System/Orion vehicles, and even provides thrust for many commercial satellites.
Researchers are conducting extensive studies on nuclear fusion rockets that would use fission’s charged particles to power spacecraft propulsion and improve existing chemical rocket performance. If successful, such technology would enable people to reach destinations like Mars much quicker than it is currently feasible.
Nuclear technology offers great promise as an energy source for deep space missions by using small reactors on spacecraft to produce electricity and hydrogen fuel, with excess hydrogen burned off to generate additional electricity without producing pollution like fossil fuels would. NASA is exploring this type of technology through their Demonstration Rocket for Agile Cislunar Operations program known as DRACO; contract awardees including General Atomics and Blue Origin will conduct reactor design work to enable commercially available nuclear power systems for spacecraft by 2025.
