nuclear reactor works on the principal of nuclear fusion and fission
answer:✨✨Principle : A nuclear reactor works on the principle of achieving controlled chain reaction in natural Uranium 238U enriched with 235U, consequently generating large amounts of heat. A nuclear reactor consists of (1) Fuel (2) Moderator (3) Control rods (4) Radiation shielding (5) Coolant. 1.✨✨
In a nuclear power reactor, material that may undergo nuclear fission is used in a controlled manner to produce a steady supply of heat. Uranium containing a low enrichment of uranium 235 (U-235) – typically below 5% – is the most common material, although a much higher enrichment of U-235, or plutonium 239 can be used with slightly different principles.
Fission of U-235 produces two lighter elements and heat, together with either two or three neutrons containing high energy. The fission process involves splitting the nuclei of atoms using neutrons. A “controlled” chain reaction is said to occur when the number of neutrons used to bombard U-235 atoms remains constant over time.
Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago. Their long occupation, initially in varying forms of isolation as hunter-gatherers, has made the region highly diverse, second only to Africa in human genetic diversity. Settled life emerged on the subcontinent in the western margins of the Indus river basin 9,000 years ago, evolving gradually into the Indus Valley Civilisation of the third millennium BCE. By 1200 BCE, an archaic form of Sanskrit, an Indo-European language, had diffused into India from the northwest, unfolding as the language of the Rigveda, and recording the dawning of Hinduism in India. The Dravidian languages of India were supplanted in the northern and western regions. By 400 BCE, stratification and exclusion by caste had emerged within Hinduism, and Buddhism and Jainism had arisen, proclaiming social orders unlinked to heredity. Early political consolidations gave rise to the loose-knit Maurya and Gupta Empires based in the Ganges Basin. Their collective era was suffused with wide-ranging creativity, but also marked by the declining status of women, and the incorporation of untouchability into an organised system of belief.[g] In South India, the Middle kingdoms exported Dravidian-languages scripts and religious cultures to the kingdoms of Southeast Asia
Nuclear fission creates heat. The main job of a reactor is to house and control nuclear fission—a process where atoms split and release energy. Reactors use uranium for nuclear fuel. ... The heat created by fission turns the water into steam, which spins a turbine to produce carbon-free electricity.
