NUCLEAR REACTORS A nuclear reactor is a device to initiate and control a sustained nuclear chain reaction. Nuclear reactors are used at nuclear power plants for electricity generation and in propulsion of ships. Heat from nuclear fission is passed to a working fluid (water or gas)‚ which runs through turbines. These either drive a ship’s propellers or turn electrical generators. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are

Innovation and Technology 165 8 Innovation and Technology INTRODUCTION 8.1. Since Independence‚ India has endeavoured to bring economic and social change through science and technology. The effort has been both on upgrading the traditional skills to make them relevant and competitive and developing advanced capabilities in frontier areas of science and technology. The visionaries who led the growth of science and technology (S&T) in India were convinced that S&T could play an important

claim that nuclear weapons are vital shields for the planet. They claim that nuclear weapons are deterrents that prevent the world from breaking out in total war. Researchers are supporting this argument by declaring how nuclear weapons have been keeping peace. However‚ other researchers and scientists deny the effectiveness of nuclear weapons as deterrents and declare that nuclear weapons will lead the world into total devastation. Many people throughout the world state that nuclear weapons have

world without nuclear weapons would be less stable and more dangerous for all of us.” In the article “Get real: nuclear power is in your future” Allan Kupcis argues that nuclear power is a necessity to maintain “the backbone of any economy.” Thus‚ in our day to days living‚ we seem to ask ourselves about what is meant by the term "Nuclear Energy." Some will give the right concept of the nuclear energy but others will not. It all depends with the knowledge one has about the nuclear energy. In this

What is Nuclear Proliferation? Nuclear Proliferation is the spread of nuclear weapons‚ fissile material‚ and weapons-applicable nuclear technology and information‚ to nations which are not recognized as “Nuclear Weapon States” by the Treaty on the Nonproliferation of Nuclear Weapons; also known as Nuclear Proliferation Treaty or NPT. The purpose of the treaty was to help avoid the spread of nuclear weapons to those countries that have not been recognized as nuclear weapons states. NPT has

Nuclear World If a nuclear bomb was dropped on your city‚ how would you survive? The blast from the fission bomb on Hiroshima‚ which weighed 30 kilotons‚ was equivalent to 12‚500 tons of TNT. Now‚ if this was dropped right outside your house‚ there would be no way of survival. But‚ one megaton hydrogen bomb is said to have 80 times the explosive intensity of the fission bomb detonated in 1945. The destructive force of the hydrogen bomb is near unimaginable. But first‚ let’s take a

Nuclear Medicine Nuclear medicine has been around for more than 50 years now and stems from the discovery of x-rays and artificial radioactivity. In 1946‚ nuclear medicine made a monumental breakthrough when radioactive iodine led to the complete disappearance of cancer in a patient’s thyroid. Nuclear medicine became widely used in the 1950’s to measure the function of the thyroid‚ to diagnose thyroid disease‚ and for the treatment of patients with hyperthyroidism. By the 1970’s nuclear medicine
