Since only <strong>U-235 is fissile<\/strong>, it must be <strong>enriched<\/strong> for use in reactors and weapons.<\/li>\n<li><strong>Nuclear power reactors<\/strong> require uranium with <strong>3-20% U-235<\/strong>, while <strong>nuclear weapons<\/strong> need <strong>90% enrichment<\/strong>.<\/li>\n<li><strong>Iran\u2019s uranium enrichment program<\/strong> has drawn global attention, with thousands of <strong>advanced centrifuges<\/strong> being deployed.<\/li>\n<\/ul>\n<h2>What is a Centrifuge?<\/h2>\n<ul>\n<li>A <strong>centrifuge<\/strong> is a device that separates substances based on <strong>density<\/strong> using <strong>centrifugal force<\/strong>.<\/li>\n<li>Used extensively in <strong>scientific research, medical applications<\/strong>, and <strong>nuclear technology<\/strong>.<\/li>\n<\/ul>\n<h2>How Centrifuges Work in Uranium Enrichment<\/h2>\n<ul>\n<li><strong>Uranium conversion<\/strong>: Uranium is converted into <strong>uranium hexafluoride (UF\u2086)<\/strong> gas.<\/li>\n<li><strong>Centrifugation process<\/strong>: UF\u2086 gas is introduced into <strong>high-speed centrifuges<\/strong> spinning at <strong>50,000 RPM (revolutions per minute)<\/strong>.\n<ul>\n<li><strong>Heavier U-238 isotopes move outward<\/strong>, while <strong>lighter U-235 isotopes concentrate towards the center<\/strong>.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Gradual Enrichment<\/strong>: The U-235-rich fraction is transferred to <strong>additional centrifuges<\/strong> to increase purity further.\n<ul>\n<li>Over multiple <strong>separation stages<\/strong>, uranium is enriched to the desired levels.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h3>Key Components of a Centrifuge<\/h3>\n<ul>\n<li><strong>Rotor<\/strong>: The spinning component that creates centrifugal force.<\/li>\n<li><strong>Chamber<\/strong>: Holds the uranium gas for separation.<\/li>\n<li><strong>Material<\/strong>: Typically made of <strong>carbon fiber<\/strong> or other lightweight yet strong materials to withstand high speeds.<\/li>\n<\/ul>\n<h2>Centrifuge FAQs<\/h2>\n<p><strong>Q1.<\/strong> What is a centrifuge?<br \/>\n<strong>Ans.<\/strong> A centrifuge is a device that uses rotational force to separate components of a mixture based on density.<\/p>\n<p><strong>Q2. <\/strong>What are the uses of centrifuges?<br \/>\n<strong>Ans.<\/strong> They are used in medical labs, industrial processing, nuclear enrichment, and space research.<\/p>\n<p><strong>Q3. <\/strong>How are centrifuges used in nuclear technology?<br \/>\n<strong>Ans.<\/strong> They enrich uranium by separating uranium-235 from uranium-238 for nuclear reactors or weapons.<\/p>\n<p><strong>Q4. <\/strong>What is the difference between gas and ultracentrifuges?<br \/>\n<strong>Ans.<\/strong> Gas centrifuges are used for nuclear enrichment, while ultracentrifuges are used for high-speed separation in biological and chemical research.<\/p>\n<p><strong>Source: <\/strong><a
